Supply ammo: 2

Sectoid

Sectoids are the weakest and the most fragile aliens - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Sectoids are the weakest and the most fragile aliens. They use laser pistols which cause rather little damage. They are very fragile for all types of attacks, especially when you aim at head. Their only advantage is mobility: they climb very skillfully and run between covers.

Sectoids alone aren't a threat, so they are used as a cannon fodder. It means, that you can eliminate them whenever you like.

Outsider

Outsider is the most common enemy in the game, They use rapid firing but very inaccurate Laser SMG and can throw grenades - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Outsider is the most common enemy in the game, They use rapid firing but very inaccurate Laser SMG and can throw grenades. They are medium endure against normal weapons, but grenades and sniper shots eliminate them quickly (like also ability Critical Strike). They like to hide behind covers, but usually some part of them sticks out, so they are an easy target. But you can't underestimate them: numerous, they can be dangerous, especially while supported by Muton, Dron or Shield Commander.

Drone

Drones are flying devices which can cause rather significant damage with missiles - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Drones are flying devices which can cause rather significant damage with missiles. But their biggest asset is an ability of healing: that's why they are a high priority target in every battle. Luckily, they are very fragile: one Critical Strike or series from any machine gun eliminates them. The only difficulty is their side: they are very small and because of that difficult to hit.

Shield Commander

Shield Commander is incredibly annoying unit - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Shield Commander is incredibly annoying unit. It can shield allies with special regenerating shields. That's why, this enemy is a high priority target: enemies augmented with shields are much more challenging, so you can't let that happen.

Unfortunately, a Shield Commander is a difficult enemy himself. Eliminating him requires concentrated fire of all team (he also has a shield). Luckily, he is not very mobile and causes small damage, so you can surround him. The best is to use grenades against him.

Muton

Muton is a very tough enemy: he has strong armor and very high amount of HP - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Muton is a very tough enemy: he has strong armor and very high amount of HP. He uses special alien's shotgun, Scatter Laser, which causes huge damage for short distance. Approaching him agents have to be careful about his fists: when he is enraged, he hits the ground causing a small Pulse Wave which causes a lot of chaos.

The most important while fighting Muton is not to get too close to him and fire at him constantly. He is very slow, but you can additionally decrease his mobility with proper abilities, mines or grenades. This is the very best possible tactic.

Sectopod

Sectopod is an advanced alien vehicle which has incredible firepower and deadly area attack (stomp made when agents are too close to it) - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Sectopod is an advanced alien vehicle which has incredible firepower and deadly area attack (stomp made when agents are too close to it). It's heavily armored and surprisingly mobile. Walking him around has no sense, because this machine rotates very quickly.

There is a way to eliminate a Sectopod - you have to break the glass on its "head" and then kill a pilot. The machine will fall down and explode in spectacular way.

Heavy Sectopod has more HP than his weaker brother and uses powerful cannon.

Gunship

Gunship is a flying vehicle used by aliens and present in Doctor mission, where it plays a role of boss - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Gunship is a flying vehicle used by aliens and present in Doctor mission, where it plays a role of boss. It fires laser beams which can quickly kill Bureau agents. It hovers and changes position a lot: so you have to change your positions also and look for covers.

A key to win with this flying fortress is a normal, oldschool firing: all members of squad should focus on fighting. What is surprising, the best weapon to use in this fight is a sniper rifle causing huge damage. Use this opportunity and load the machine with bullets.

Elite Outsider

This enemy is called elite for a reason - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

This enemy is called elite for a reason. He has more HP than his weaker kinsmen, fires more accurate and causes more damage. For this isn't enough, he has also regenerating shield and upgrades which allows him for hand-to-hand combat. So, you have to keep Elite Outsider at bay and fire at him constantly: first eliminate his shield and then himself. And very important is to not give him any free time, because he'll regenerate shields and return on the battlefield.

Silacoid

Silacoids are small, nasty creatures which hide in dark corners of the map (like shafts) and then immediately jumps out at squads members - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Silacoids are small, nasty creatures which hide in dark corners of the map (like shafts) and then immediately jumps out at squad's members. They cause huge damage in direct fights and are very mobile. Luckily, they die from any hit so you can eliminate them very easily. Carter can't hurt his teammates (there is no friendly fire in this game), so he can fire at the enemies which are on allies.

Rocket Sniper

Rocket Snipers are really pain in the ass - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Rocket Snipers are really pain in the ass. They hide in the far corners of map, aim agents and then fire series of deadly rockets. Their projectiles are so powerful, that they can crush the cover and kill people behind it. Luckily, they always reveal their position before shooting: they use laser sight, which helps in finding them. So it's good idea to have a sniper rifle or recon with ability Critical Strike to get rid off the danger immediately.

Advanced Drone

Upgraded Drone, like its weaker version, causes lot of damage on medium distance - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Upgraded Drone, like its weaker version, causes lot of damage on medium distance. What is more, it can lift agents what makes them additionally fragile and make impossible to do anything. It has also a lot of HP, so it's not an easy target.

In spite of all, one longer series from machine gun or concentrated fire of all squad is enough to eliminate this device.

Titan

Titan is a powerful boss met in mission Signal from Beyond - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Titan is a powerful boss met in mission Signal from Beyond. He has powerful laser cannon which destroys every target and covers. He flies around on the battlefield, so there is no safe zone. A key to win is to change covers constantly and fire at him with blaster launcher. His weak spot is a middle ring: if you hit there, damage is multiplied.

Tech Commander

Tech Commander is an upgraded and more dangerous version of Shield Commander - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Tech Commander is an upgraded and more dangerous version of Shield Commander. He can not only protect allies with shields but also create Turrets, repair machines and make big covers. He deals little damage but has really powerful abilities. Because of that he becomes your priority target during encounters: you have to destroy his shields ASAP and then eliminate (one Critical Strike isn't enough for that).

Sniper Elite

This alien is a regular sniper - he deals huge damage from long distance and misses very rarely - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

This alien is a regular sniper - he deals huge damage from long distance and misses very rarely. Luckily, you can spot him with laser sight.

As he uses advanced shield, you can't kill him with a single headshot. You need at least two hits sniper rifle or longer series of machine gun. When the shields are down, he is very fragile, you can kill him even with standard pistol.

Phantom / Elite Phantom

The main asset of this alien is an improbable speed and ability to camouflage: he can flank humans easily and deals huge damage on short distance - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

The main asset of this alien is an improbable speed and ability to camouflage: he can flank humans easily and deals huge damage on short distance. He is rather dangerous and difficult to spot during the encounter. Luckily, he has small number of HP, so few good shots and he is eliminated. You have to consider this and eliminate nearby Phantoms relatively quickly: you'll lose little of time and save your people from death.

Phantoms have two version: normal and elite. The only difference is that the latter ones have personal shields.

Axis

Axis has strong shields, can teleport, fires accurately and deadly and, also, has a powerful area attack dealing huge damage to the whole squad - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Axis has strong shields, can teleport, fires accurately and deadly and, also, has a powerful area attack dealing huge damage to the whole squad. During fighting him, you shouldn't use abilities affecting small area because this alien will avoid them easily grenades also (unless he has already use teleportation - it has a several seconds of cooldown). The better idea is to summon Silacoid, supported by a Drone (Carter's abilities) and firing at him constantly by agent Weaver. Simultaneously, you can't forget about healing the squad and keeping an alien at bay.

Elite Muton

Mutons are powerful enemies, but their Elite leaders are far more challenging - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Mutons are powerful enemies, but their Elite leaders are far more challenging. They have not only more HP, better armor and more effective weapons but also several deadly abilities. First of them is a long jump, which causes a destroying shock wave when he hits the ground. Another one is a possibility of creating Plasma Field: the same like the commandos can. If it's not enough, Elite Muton deals also huge damage at short distance.

A tactic use for encountering normal Mutons (stopping an enemy and usage of area attacks) won't work because an enemy is too mobile. So you have to change your pAxistions, run away and summon allies like Silacoid or Drone (Carter's abilities). Important is firing at the enemy all the time and destroying his armor. Useful will be Blaster Launcher and ability called Weaken, used by support agents.

Mu'ut Jeen / Psion Commander

This psion is a kind of a boss, which you can meet during Operation Hawkeye - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

This psion is a kind of a boss, which you can meet during Operation Hawkeye. He can clone himself and stun Carter's companions during a direct fight, preferring grenades firing from Plasma Assault Cannon and melee fighting. He has strong shields but not so many HP. He is insensible for Taunt and Lift what makes him unpleasant enemy - especially, that he eliminates human shields rather easily.

Defeat him in a conventional way: fire, fire, fire until he dies. The important thing is to not stop assaulting because he will regenerate. When the psion dies, his clone dies also.

Minion Commander

This enemy is a real pain in the neck - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

This enemy is a real pain in the neck. He has strong shield, deals a lot of damage, can throw grenades and is very good at melee fighting. But those aren't his main features: he is a summoner. If you don't eliminate him quickly enough, he'll summon a group of Drones and several Silacoids. This makes him even more dangerous than the remaining leaders, so you have to kill him as the first one, no matter what.

Scout

Powerful alien infantryman with endure shields and an accurate Plasma Assault Cannon can also throw grenades and teleport where he wants to - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Powerful alien infantryman with endure shields and an accurate Plasma Assault Cannon can also throw grenades and teleport where he wants to. Also, he deals big damage in melee fight and is rather quick. One of the most challenging enemies in the game almost without weak points. The only effective way of fighting him is Lifting him with proper ability of Carter and firing him down quickly. It is so because this enemy will avoid all area attacks and conventional attacks will take him down very slowly.

This type of enemy may become a very strong support during further battles. It's a good idea to hypnotize them (ability: Mind Control) and use on the battlefield.

Infiltrator

You meet Infiltrator two times: during your first visit in the base and in the mission The Last War - Enemies - The Bureau: XCOM Declassified - Game Guide and Walkthrough

You meet Infiltrator two times: during your first visit in the base and in the mission The Last War. During the first time, he can summon Sectoids, has strong shields and fires with short but deadly series. During the second encounter, the situation changes: he is as tough as he was, but this time he can summon Drones and teleport. But alone he is not that tough, so you should take him down without problems.

There are five classes in the game, every with specific abilities. Carter gets an access to agent selection immediately after visiting the base (look at: Missions: Welcome to XCOM) and from now on, he decides about the members of the squad.

Here you can recruit agents. - Classes and abilities - The Bureau: XCOM Declassified - Game Guide and WalkthroughHere you can recruit agents.

Computer in the Ready Room allows you to hire new agents and modify the hired ones. You can have maximum three people in the squad (including Carter), so you have to choose very wisely. The worst situation is when your teammates have similar abilities: they are not very unique/universal and falls badly against untypical enemies (e.g. armored, flying or hidden behind covers). There is no optimal/best squad - choice depends on your personal preferences and playstyle. But in the one of following chapters you'll see a proposition of combination which seems to be very effective (according to guide's author).

Varied squad is a base. - Classes and abilities - The Bureau: XCOM Declassified - Game Guide and WalkthroughVaried squad is a base.

Carter has a special, unique class, unavailable for others. The rest of Bureau agents is divided onto four classes:

  • Support;
  • Recon;
  • Engineer;
  • Commando.

Every of them has also six smaller subclasses, which decide about first passive skill (look at: following chapters of guide).

Newbies wont have a chance against advanced enemies. - Classes and abilities - The Bureau: XCOM Declassified - Game Guide and WalkthroughNewbies won't have a chance against advanced enemies.

Every hero is very important on the battlefield and you have to care about them. It's even more important because you can't change chosen agents within the mission: such an option appears only when you play at two lowest difficulty levels.

Remember also, that Carter and his friends gain experience during the game, what gives them new abilities and (not always) more HP. It means, that veterans are much better than freshly recruited newbies.

Carter is unique. - Agent Carter - Classes and abilities - The Bureau: XCOM Declassified - Game Guide and WalkthroughCarter is unique.

Agent Carter is a very specific hero, without any particular class, but with many useful abilities. He is the only one in team who can heal allies, and he also uses grenades very well. With levels, he gain specific skills which can decide about the result of the battle. Death of Carter ends mission, so you have to care primarily about him.

Carter can use all types of weapons, what makes him very universal.

Engineers provide you with technical support. - Engineer - Classes and abilities - The Bureau: XCOM Declassified - Game Guide and WalkthroughEngineers provide you with technical support.

Engineers specialize in setting up useful devices on battlefield: they can set up mines and create advanced XCOM cannons which deal huge damage and are endure. Those agents don't fit into direct fight, because they deal minimum damage and use shotguns efficient only for short distances. Mines also aren't too useful as aliens routes are difficult to predict. So, as you can see, the main asset of an engineer is an ability to set up cannons.

Commandos is specialized in taking damage. - Commandos - Classes and abilities - The Bureau: XCOM Declassified - Game Guide and WalkthroughCommandos is specialized in taking damage.

Commandos is an agent who has to take enemy fire at him, what makes him very similar to tanks in MMO games or MOBAs. He uses rifles and causes a lot of damage for short and medium distance, but he rarely kills anyone. he's useful for luring enemies out from behind covers (Taunt) and shows his true value on higher levels: then a commandos can eliminate all groups of enemies with Plasma Field.

Commandos divide on six subclasses. Every of them provides you with different bonus:

Engineers become useful at the end of the game. - Suggested Squad - Classes and abilities - The Bureau: XCOM Declassified - Game Guide and WalkthroughEngineers become useful at the end of the game.

There is no optimal set of squad members in this game: their skills complement one another in such a way that every combination seems to be interesting. The only thing you should avoid is to have two identical agents, e.g. two commandos or engineers in one squad. Such team isn't to flexible and universal. You will meet very different enemies in the game, so the number of options that you have, should be rather wide.

Below you can find a set which seems to be the most effective and offering the biggest number of tactical options. It doesn't mean that this is the only one right: the game is made for you to made experiments. So the hints below should be treated rather like suggestions.

Critical Strike is super. - Suggested Squad - Classes and abilities - The Bureau: XCOM Declassified - Game Guide and WalkthroughCritical Strike is super.

Team without a recon isn't a team. This agent is perfect for all types of enemies and his Critical Strike let him eliminate immediately Silacoids, Sectoids, Drones and Outsiders. On the third level you also gets a useful ability, Diversion, thanks to which he can drag enemies out from Carter and his squad. He also gets Fire Mission, the most powerful ability in the game, which allows you to eliminate whole groups of enemies. This combination is deadly, but has one drawback: recon is easy to kill, so you have to keep him away from the direct battle. To do so, the best choice is to have a commandos.

Plasma Field is better than a grenade. - Suggested Squad - Classes and abilities - The Bureau: XCOM Declassified - Game Guide and WalkthroughPlasma Field is better than a grenade.

The main role of commandos is to keep aliens away from recon and Carter. He has a lot of HP and is tougher than the two of them. He doesn't deal a lot of damage, but he has two very useful abilities: Taunt and Plasma Field. The first one lets you lure out enemies from behind covers and the other one eliminates whole groups of enemies. This combination is especially deadly, when Carter has sniper rifle or blaster launcher. Thanks to that he can eliminate even the strongest enemies taunted by commandos.

Fire Mission wins all. - Suggested Squad - Classes and abilities - The Bureau: XCOM Declassified - Game Guide and WalkthroughFire Mission wins all.

Combination with recon and commandos seems to be the most effective also because other classes don't offer too much at the first levels of experience. The best ability of engineer, Laser Turret is available not before the fourth level, what happens very late in the game. Support agents are focused on defence so they increase survivality of the team but don't deal any damage.

The remarks below don't cross out engineers and support agents from any squad, but combination recon + commandos seems to be most profitable.

Beginning is an introduction to the game mechanics. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughBeginning is an introduction to the game mechanics.

Game begins with tutorial. After a cut scene look around in Carter's room. Using keys to move, walk around and look at the suitcase. In this moment, the hero will see that he has lost his cargo. You can exit the location by the door opposite to the window.

Finding covers is essential. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughFinding covers is essential.

Go to the corridor and turn behind the corner. When you see an alien ship, sprint to the wall and hide under the parapet. Carter bends automatically when you press sprint button. Soldier you meet here is killed by aliens - you can't do anything.

Jumping between covers helps you avoid troubles. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughJumping between covers helps you avoid troubles.

Crawl right, avoid aliens' bullets. When you get to uncovered part of the wall, jump to the next wall (press sprint button and direction in which you want go).

You can jump over small obstacles. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughYou can jump over small obstacles.

Glue out of the wall and walk to the door. Keep to the left side of room and jump over fallen cupboard. Go downstairs and through few rooms until you get to the exit. On your way you find no enemies, so you can look around. But there are no interactive objects.

USA are in fire. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughUSA are in fire.

Go left, pass burning airplane. Use its wings as a cover and prepare for the first battle. In front of you, you will see few Sectoids, the weakest and the most fragile type of enemies. Aim at them and kill.

Headshot usually solves all problems. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughHeadshot usually solves all problems.

When you kill the first pair, few more appears. Then, lean out from behind the cover and fire at their heads. Remember that the best moment to shot them down is when they're reloading.

90s smartphone. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and Walkthrough90s smartphone.

When the aliens are dead, enter the building in front of you. You meet there agent Nils and use radio (lies on the table, screen above). When the conversation is over, leave the room using the exit on left.

First collectible. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughFirst collectible.

Go upstairs and look around. On the desk next to the agent Nils you find first collectible in the game: photo of laboratory entrance.

Aliens arent fooling around. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAliens aren't fooling around.

Go through door secured by your companion and exit the building. Head for the closest building and go upstairs. Now, the sudden explosion separates you from agent Nils

Rifle is better than a pistol. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughRifle is better than a pistol.

Enter the storehouse and pick up M14 Rifle, dropped by a dead soldier. Thanks to that you can eliminate bigger groups of aliens in shorter time. Remember to use short series, because recoil decreases accuracy of Carter.

Enemies can hide - their heads stick out. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughEnemies can hide - their heads stick out.

Press button which opens door to hangar and hide behind crates. When agent Nils runs into the room below, open the window and help your companion. In front of you, a small squad of Sectoids appear - you shouldn't have too much problems with them. As you're on the high ground, you can fire at enemies hiding behind covers.

Here, the enemies are immortal. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughHere, the enemies are immortal.

When the danger is done, go through door on left and meet with agent Nils. Move forward, go through the flooded room and jump into the burning hole. A bit later you find two aliens torment a fighter pilot: but you can't help him, move on. Pass them and follow the only possible path.

Leaning out in this moment would be a suicide. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughLeaning out in this moment would be a suicide.

American tanks, which you will see, will be quickly destroyed by an alien ship - you can't do anything about it either. So approach them and hide behind a cover on left. You will be fired at by Gun Turret. And you can't handle it by yourself.

Flanking enemies is crucial. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughFlanking enemies is crucial.

Move to the focus mode and order agent Nils to walk the enemy around from right. From the available option choose Move and use proper keys to place him, just behind a Turret. It's shown on the screen above.

Critical Strike is one of the best snipers abilities. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughCritical Strike is one of the best sniper's abilities.

When Carter's ally is on the position, choose his ability Critical Strike and aim at a Turret. As it was damaged, one shot is enough. Notice that agent Nils obtained a solid bonus to damage because of flanking the enemy.

You can also eliminate enemies in 0other way. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughYou can also eliminate enemies in 0other way.

When the enemy fortification is blow up, another enemies will appear: Sectoids. But you don't have to worry: positioning of Carter and agent Nils works for you, so elimination shouldn't be a problem. After that, pick up rifles and pistols and then enter the building in front of you. There you'll find few additional weapons and ammo pack.

Mysterious hole isnt made by human. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughMysterious hole isn't made by human.

Go through the main hall of building, picking up everything you want and then jump out through the hole in the wall. When the street in front of Carter explodes, approach the crater and look at it. Then, head for the hangar in front of you.

Enemies are not prepared for an attack. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughEnemies are not prepared for an attack.

Run into it and hide behind a fork-lift truck picking up grenades from it (screen above). Order Nils to hide behind crates on left. In front of you, you see three enemies: two Sectoids and an Outsider. Use Critical Strike of Nils and kill the new enemy. This choice has a sense: Outsider is a primary target as he has a lot more HP than his weaker companions. Luckily, a good eye of your ally is enough for quick and effortless elimination of enemy.

Shotgun is useful for short distances. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughShotgun is useful for short distances.

When you kill all enemies, look around carefully in this room. You'll find few additional grenades and rifles. Look also to the room on right and search crates at the elevator, you find there two M1897 Shotguns. But remember, that Carter can use only two types of guns at once.

Remark! Combination rifle plus shotgun seems to be an optimum, as the first one is good for a medium distance, while the other one for short distance. Pistol is very weak, don't regret it.

Fire Mission is one of the most powerful abilities in the game. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughFire Mission is one of the most powerful abilities in the game.

When you press elevator button, two Outsiders enter the hangar. Eliminate them as you like and prepare for a longer battle. After a while, a Drop Pod, few more Outsiders and a Drone appear in the chamber. This fight you can play in two ways: by conventional fire, killing enemies one after another or with Fire Mission ability owned by agent Nils. The second option is more profitable as you can kill enemies and eliminate the device from which they are coming out at once.

If you chose the more difficult option, begin from killing a Drone which can heal allies. That will spare you a lot of problems.

Letter was left at the screens. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughLetter was left at the screens.

When the danger is eliminated, enter the elevator and ride down. Go to the room in front of you and, in room with screens, find a letter, another collectible. In the nearby corridor you can find more ammo and swap any weapon for a pistol (not recommended).

Rather untypical place for this item. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughRather untypical place for this item.

Moving forward, you get to a room with world map and a projector. On the table with the device, you can find a photo which shows weird symbols. If you are curious, you can approach the displayed picture and talk about it with agent Nils.

More symbols. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughMore symbols.

Enter the shed with TV and two bodies. On the small table you find another photo. When you stop enjoying this view, exit the room by the door on left. Then, follow the only possible path through next corridors and finally meet up with Faulke. Following events will come in the same way independently from your choices.

Choices in this conversation dont have any influence. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughChoices in this conversation don't have any influence.

When you finish the conversation, your boss sends you to the other part of base. Notice, that you get another man in your squad: agent Kinney, an engineer. He specializes in setting up traps and frightening aliens, what is a useful combination.

XCOM Turret is very helpful in small rooms. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughXCOM Turret is very helpful in small rooms.

Move forward, along the corridor. When you get to the staircase, look on the floor above where you find a rifle. Then go to the very bottom and prepare to the battle. In the laboratory, you find several Outsiders and Sectoids, who can be challenging. An optimal way of destroying them is to set up XCOM Turret in the middle of the room (use an ability of agent Kinney). It should be enough, but enemy may try to walk you from the right flank. In this case, use a grenade or Critical Strike.

Alien invasion isnt a good moment for writing letters. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAlien invasion isn't a good moment for writing letters.

After this fight, look around. On right you find a shotgun, on left a mysterious aliens' artifact (unfortunately, you can't pick it up, only talk about it). By the way - you can look under the column next to the exit from the room, you find there another letter.

Hidden enemies can be smoked out with grenades. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughHidden enemies can be smoked out with grenades.

When you exit the room, move forward until you find two Outsiders hiding behind a crate (you can see them in focus mode, screen above). The best way to eliminate is to throw a grenade. Notice also that just next to it you can find a ammo pack, grenades and a rifle.

Kinney can set up a Turret while hiding behind a cover. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughKinney can set up a Turret while hiding behind a cover.

Follow the only possible path until you get to the room with aliens and enemy Turret. The best thing to do is to send agent Nils on the back of the room and place him behind a cover - as a sniper, he doesn't have to be close to enemies. Kinney's task should be setting up Turret XCOM just before the alien barricade to nail them down and keep them in one place. In this moment, let them taste a grenade and then eliminate they automatic rifle. Remainings may be defeated by agent Nils, who almost always makes a hit. This way of fighting is the optimal one.

Another letter on the desk. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAnother letter on the desk.

After replenishing ammo and grenades (plenty of them in the room) you can approach a part of bomb and talk about it with companions. Finally, go to the exit and move on. Pass an alien device and enter the location from where you hear weird sounds. Kill a Sectoid inside and pick up a letter from the desk. Then, look into the cupboard at the door and pick up another note. Go through door and watch a cut scene.

Choices dont matter. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughChoices don't matter.

During this conversation, you don't have to care: your dialogue choices don't matter at all here. You can freely move on to another confrontation. On your way, you find several Sectoids and Outsiders, who can be easily flanked from both sides. It's a good idea to set up a XCOM Turret in the middle of the room and use grenades if there is a need.

Remember: grenades may bounce from obstacles and return to you. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughRemember: grenades may bounce from obstacles and return to you.

Replenish supplies after a battle and then launch a train in front of you. Watch a cut scene and prepare for a change of scenery. Make yourself comfortable in the new location and pick up everything you think will be useful. In a moment, you'll fight an overnumbering troops of enemies.

Sniper rifle - it will be your best friend. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSniper rifle - it will be your best friend.

Walk on the platform on the top and pick up sniper rifle. Sniper rifle is one of the best and most useful weapon in this game: it allows for the long distance fight (and this is how the battle takes place, mostly) and deals a lot of damage. So, this weapon will be an invaluable help during combats whatever your playstyle is. As the second weapon, I recommend M14 Rifle because it's very universal. This set seems to be good at this stage of the game.

Enemies will appear after a radio talk. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughEnemies will appear after a radio talk.

When you equip enough, approach radio and contact the base. After that, Drop Pods with Outsiders and Sectoids appear in front of you. You can eliminate them with companions' abilities: Laser Turret or Fire Mission. Conventional way of eliminating them is a bit problematic but thanks to flanking bonus you should make it.

Good Fire Mission ends battle immediately. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughGood Fire Mission ends battle immediately.

Another wave appears when the first one is eliminated - this one is a bit stronger, but still defeatable. Crucial is to not let any squad member to go to the bottom of platform, because it's a pure suicide. Notice, that enemies spread after landing and try to go upstairs using the left side: so you can mines this area. An alternate option is to use grenades or sniper rifle.

Enemies appear after launching a computer. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughEnemies appear after launching a computer.

When it's done, approach the computer in the middle of location and then launch testing sequence. There is over a minute to an explosion: you have to withstand allies to this moment.

Escape is the only way to a victory here. - Chapter I: Invasion! - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughEscape is the only way to a victory here.

Enter the helicopter field and replenish ammo (nearby you find another sniper rifle and bag with bullets). Tell Kinney to set up a Turret at only stairs leading up and then prepare for a battle. In front of you the indestructible Drop Pods appear with unlimited numbers of enemies: Outsiders and Drones. You can't win this fight, so fire at enemies until the help arrives. When the chopper flies to you run to it, run!

Remark! If you don't make it on time, the bomb will kill Carter!

Welcome to the Bureau! - Base Visit I: Welcome to XCOM - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughWelcome to the Bureau!

Beginning sequence is not interactive, agent Carter has a tour around the Bureau. Only after a longer moment you regain control.

Agent DaSilva - one of the best agents of Bureau. - Base Visit I: Welcome to XCOM - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAgent DaSilva - one of the best agents of Bureau.

Your first interactive action here is a conversation with agent Nico DaSilva. Choices made in this conversation won't affect anything in the future, so you can play it as you like.

Bureau agents like to know with who theyre working. - Base Visit I: Welcome to XCOM - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughBureau agents like to know with who they're working.

If you're interested in the past of your newly gained friend, you can look into his files on your desk (your own files are on the DaSilva's desk, on the opposite).

When you exit the room, another cut scene triggers. After that, another conversation with DaSilva, during which you can talk about radio. If you do so, you begin an Investigation: Radio Interference (otherwise, the mission begins automatically a moment later).

Listening to the records let you understand the storyline better. - Base Visit I: Welcome to XCOM - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughListening to the records let you understand the storyline better.

Independently on your action with radio, you'll have to meet Faulke in his office. To do so, leave Carter's office and go upstairs (stairs on the left side of the room with a display). But before you talk with your chef, listen to recordings - one can be found in the office, the other one in opposite room. By the way you can also read a note from the Faulke's secretary desk. You don't have to bother with collectibles if you don't want to - they don't affect the storyline.

Agents dont waste time. - Base Visit I: Welcome to XCOM - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAgents don't waste time.

After a conversation with Faulke (during which you have no important decision to make) you have to meet with DaSilva. Go on the lower floor of the base and walk through door with two guards. Then turn right and enter a big room with soldiers. By the way you can listen to recordings, read a letter in the corner and watch a photo at the table with maps. When it's done, approach the computer in the middle of the room and choose two new agents to your squad (look at chapter: Classes and Abilities).

There is always something to do in Bureau. - Base Visit I: Welcome to XCOM - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThere is always something to do in Bureau.

When you walk off from the computer, you get a message from agent Nils - he tells you that something bad is happening in the mortuary. Exit this room using the door on left and then head for an elevator at the end of corridor. You'll be moved to a hangar with helicopter. On the right you see files on the pile of cartons: you can look at them if you want.

The alien had no problems in getting to the base. - Base Visit I: Welcome to XCOM - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThe alien had no problems in getting to the base.

Turn left and enter the mortuary. Being in the vestibule, read a medical note hanging on the cupboard with medicines (left side of room). Then prepare for a storyline twist and fight because the next room is a picture of disaster. Follow the blood trails until you get to the body of agent Nils. In this moment you find an alien Infiltrator and the battle begins.

Infiltrator is your main target. - Base Visit I: Welcome to XCOM - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughInfiltrator is your main target.

Infiltrator is an advanced enemy. He can summon Sectoids, throw grenades and deal big damage. He has also a regenerating shield. She can't be affected with Taunt, so commandos tactic is a failure. The best way to fight is to conduct a massive fire and throw grenades. You shouldn't bothered with summoned Sectoids, they'll appear as long as their commander lives. The most important is to eliminate the main target ASAP and don't let his shield to regenerate.

You can practice on the Firing Range. - Base Visit I: Welcome to XCOM - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughYou can practice on the Firing Range.

Return to Faulke and report. On your way you can talk with agent DaSilva at the helicopter, Web in the ready room, new agent on the Firing Range and Percy in Hiring Room. None of this conversation matters: you can make them, but you don't have to. Notice also a note attached at the door to Firing Range.

Dr Dresner has unpleasant past. - Base Visit I: Welcome to XCOM - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughDr Dresner has unpleasant past.

On your way to Faulke, you'll be accosted by doctor Heinrich Dresner, who gives you a weird device. It's a good moment to make a detour and search freshly unlocked locations. First, turn right and look for a note next to the cartons nearby Operations. Then go through Disinfection Room and enter the doctor's laboratory. There, you find four more notes and you can talk with Krut and doctor Dresner. It doesn't have meaning for a storyline, but you should know the history better, right?

You have no choice for now on - there is only one mission. - Base Visit I: Welcome to XCOM - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughYou have no choice for now on - there is only one mission.

When all those things are done, enter the Operations and meet Faulke. Then approach the computer in the middle of the room and launch another mission - The Doctor (others are unavailable). You'll return to the Bureau only after finishing it so make sure, that you've done all necessary things. It's important, because after every missions new collectibles and dialogue options appear and the base changes. So if you don't do something now, you won't have a chance for making it later.

Radio message sounds like a mantra. - Investigation: Radio Interference - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughRadio message sounds like a mantra.

First Investigation is rather simple: when you wake up, talk to DaSilva about radio standing at the end of the desk. Approach the device and launch it. You'll hear a weird announcement, containing numbers and name of the month. Carter will write this down on the piece of the paper next to the radio.

Correct combination is : 250, north, 892. - Investigation: Radio Interference - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughCorrect combination is : 250, north, 892.

Go to the communication opposite to your room. Talk with officer Chulsky and talk her about a weird signal in radio. Then give her correct coordinates, which are: 250, north, 892. Congratulations, you have saved few humans against aliens!

Does the mysterious deer have something in common with alien invasion? - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughDoes the mysterious deer have something in common with alien invasion?

Mission begins peacefully. During first few minutes you won't meet up with aliens, so you can explore the area. But there isn't much of a walking: you can go forward along the only path, because other passages are blocked. So move forward until you get to the barricade. Then, turn right and enter a coffee shop.

Aliens change people into mindless zombies. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAliens change people into mindless zombies.

Inside you find a man infected by aliens. When the cut scene ends, listen to recordings next to the sick one, you'll know something more. Then exit the building through door behind you and look at the destroyed bus. Follow the only possible path until you get to the other bus. Turn right and enter destroyed building. Be ready as the battle is about to begin.

Shield Commander is a challenging enemy. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughShield Commander is a challenging enemy.

Few Sectoids and Outsiders with a single Shield Commander appears in front of you. The last one is your priority target, because he can protect his allies with shield. The easiest way to eliminate him is to use Taunt, commandos' ability. When enemy goes out from his cover, fire at him and throw grenades.

If you don't have a commandos, use recon's Critical Strike and massacre enemy with our firepower. This might be difficult due to enemy's shield which regenerates and because alien doesn't tend to conduct a direct fight.

X stand for location of an alien and explosive barrel - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and Walkthrough

X stand for location of an alien and explosive barrel.

The second wave appears when you clean up the first one - with several more Outsiders and two Drones. As the latter ones can heal allies, you have to eliminate them as first. Luckily, they are very fragile so one Critical Strike or short rifle series is enough to take them down.

Notice also an Outsider-sniper hiding on the roof: you can smoke him out by firing at the explosive barrel (screen above).

Location and range of mines can be seen in focus mode. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughLocation and range of mines can be seen in focus mode.

When the battle ends, collect ammo (you find sniper rifle, shotgun and three ammo packs in cars in front of you) and then disarm nearby mines. You can do it in very simple way by firing at them. When it's done, go forward until you get to closed door in front of anti-aircraft cannon. Order one of companions to open door and prepare for another attack. In the meantime, remember to choose a skill for agent Carte - he has surely leveled up.

Lifted enemies are helpless. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughLifted enemies are helpless.

Enemies will again attack in two waves: in the first one with several Outsiders, in the second one more Outsiders and single Shield Commander. Killing the latter one should be much easier than the previous time: use Lift (new Carter's ability) on him and then fire down.

Turn off alien machine and let chopper get to you. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughTurn off alien machine and let chopper get to you.

When all enemies are down, go through the freshly open door and turn off anti-aircraft cannon. Then go through the fortification and enter the bank. There you meet few more zombies, you can't talk with them. Pass them and go downstairs to the cellar.

You can help civilians, but you wont get anything for it. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughYou can help civilians, but you won't get anything for it.

There you meet a group of survivors. You can promise them help or not: when the mission ends you won't get any information about them, so you can tell that there are no consequences. Make your choice and enter the vault to pick up ammo and leave the building.

Resupply Stations are rare - use them if you can. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughResupply Stations are rare - use them if you can.

Go through the yard and then through barber. In front of you, you'll see a Resupply Station in which you can change agents, replenish ammo and change weapons or equipment. You can also look into the library on left, but there is nothing more than a shotgun.

First aliens can be killed within a second. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughFirst aliens can be killed within a second.

Jump into breach in front of Resupply Station and go to its very end. Doing so, you'll surprise three wandering Outsiders. When they're dead, you'll see two Drones, one Shield Commander few more Outsiders. You should kill them in the order above.

Drones should be killed with Critical Strike or massive fire, while Shield Commander is a piece of cake after using Lift.

Muton is a very tough enemy. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughMuton is a very tough enemy.

Move on and replenish ammo in front of the park: there you'll have to take a difficult battle with enemies. Besides standard Outsiders and Sectoids you'll face also a new enemy: Muton. This heavy armored alien has a lot of HP, deals a lot of damage on short distance (he uses alien shotguns) and can perform powerful AOE attacks. He is very dangerous on a short distance, so you have to keep him at bay and fire, fire, fire. Very useful is Lift, which slows down enemies and let you kill him easier. You can also use grenades and mines (if you have an engineer in the squad) like also Critical Strike. Finish off remaining enemies in random way, Muton is your main target and danger.

Assistants presence in destroyed building is a bit confusing. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAssistant's presence in destroyed building is a bit confusing.

Enter the university when the fight ends and find an assistant of doctor Weir. After this conversation, you can look at two photos on the blackboard and listen to recordings left on the cupboard (you can also look at doctor's documents). Then leave the room by door on right. Doing so, you find the first alien weapon which you can use: Scatter Laser. As every shotgun, it's perfect for short range but nothing more. Have said that, Laser isn't too useful.

Full assault isnt a good idea. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughFull assault isn't a good idea.

After a short walk, you get to another square full of aliens. There is a team of Outsiders and Sectoids, who don't suspect an attack: elimination of the first few shouldn't be a problem. But the problem is a fact, that there is a Turret a bit later, which can immediately eliminate Carter's men. So your optimal tactic seems to hide behind obstacles/covers and eliminate enemies one after another with short series or sniper shots. When weaker enemies are down, you can focus on the Turret.

At this stage of the game, none of squad members can deal enough damage to it. So the best way is to distract the machine with one of agents and make Carter run Turret around and eliminate it as it rotate very slowly. You can also use grenades but they will be needed later.

After replenishing ammo, go through the gate on right and prepare for a really difficult encounter - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and Walkthrough

After replenishing ammo, go through the gate on right and prepare for a really difficult encounter. In front of Carter and his squad a really Sectopod will appear. This is an advanced alien machine with heavy armor and huge firepower. Sniper weapon doesn't hurt this device, so you have to change it for something more useful (on the right side of this location you can find shotgun and Scatter Laser). Eliminate the machine ASAP or coming Outsider and Sectoids will surround and kill you.

The optimal tactic during fighting Sectopod is usage of grenades, firing at nearby explosive barrels and conduct short range fire (but enemy rotates quickly and stomps, so don't get too close). But, above all, destroy an armor on vehicle's "head" - when the glass breaks, alien inside is an easy target. You can also Lift this machine and fire at its back panels which are weaker.

Schematics let you upgrade your squad. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSchematics let you upgrade your squad.

When the fight is done, collect ammo and go through the gate in front of you: you can return to sniper rifle and throw out short distance weapon. Move forward until you get to Resupply Station and Backpack Schematic. The last one gives you very useful upgrade: Sharpshooter Pack (increases damage of headshots). Equip team with new tools and move on.

Critical Strike is perfect for Drone elimination. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughCritical Strike is perfect for Drone elimination.

When you get through few more locations, you get to a larger alien construction. There you find few Outsiders, which you can fire down without any troubles (notice also explosive barrels). Turret is far away enough, to not have any impact for this encounter.

Unfortunately, when you eliminate the first group of enemies, Shield Commander and three Drones (with more Outsiders) will appear on the battlefield. Your priority is, of course, Shield Commander - you have to lift him quickly and eliminate. Then take care of Drones, which will heal themselves. Luckily, recon can eliminate them rapidly with Critical Strike. If you don't have one in your squad, fire at them constantly and distract them: when you use Taunt, alien stops healing allies and will attack commandos. When all Drones are done, walk around the Turret from right eliminating all Outsiders on your way.

There is no ammo in next location. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThere is no ammo in next location.

After fight, collect ammo. Unfortunately, most of nearby ammo packs suit only Scatter Laser. Because of that, conventional weapon without many bullets is slightly less useful right now. During the next fight you have to think about getting more ammo. So, you have to go through few more locations and collect ammo at laboratory entrance. Watch cut scene with doctor Weir and prepare for difficult battle.

Sniper rifle is surprisingly effective. - Chapter II: The Doctor - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSniper rifle is surprisingly effective.

Carter will have to stand the whole army of Outsiders supported by single Shield Commander. What is worse, there is even a flying fortress: Gunship. Gigantic machine has a turret and deadly rockets. Those enemies force you to become very mobile: if Carter and his companions won't shift positions quick enough, the alien ship will fly them from behind and eliminate. So you have to constantly change positions and hide behind covers.

What is interesting is a fact, that the thing which deals the biggest damage to alien ship is sniper rifle and Critical Strike of recon. Use it as an asset, replenishing ammo in the meantime from the containers in the middle of the map.

When battle ends, the mission ends. You can return to the base.

The second visit in the base is very simple thing: when you finish talking to agent Weaver, you have walk to computer in Operations and choose another mission. But it'd be a waste of opportunity, as there is a lot of collectibles to find and talks to make in here now.

Seems like DaSilva is family-bond. - Base Visit II - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSeems like DaSilva is family-bond.

First collectibles can be found in Carter's office - on agent DaSilva's desk you find two photos: one of his son, and the other of some New Mexico city.

Signallers are well informed. - Base Visit II - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSignallers are well informed.

When you enter communication room, you can talk with officer Chulsky. She tells you by the way that there is a pile of files, which you can look through.

Notes will tell you interesting things. - Base Visit II - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughNotes will tell you interesting things.

In Operations turn right. On the table between computers you find few additional notes and a talkative Krut a bit further. You can also accost agent Weaver if you want, but she isn't a pleasant interlocutor.

Recordings are about Infiltrator interrogation. - Base Visit II - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughRecordings are about Infiltrator interrogation.

The two last collectibles are in Faulke's office. In the corner you find recordings, and a photo of weird device on the table.

Illusion of freedom makes you feel good. - Base Visit II - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughIllusion of freedom makes you feel good.

When collectibles and talks are done, approach the computer in Operations. This time you can choose between two missions: Guardian and Grifter. Order of making them doesn't matter.

Hay is bulletproof, you can hide behind it. - Operation: Guardian - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughHay is bulletproof, you can hide behind it.

This mission begins calmly, but it changes quickly. When you pass few first streets, you get to the truck with hay: in front of it you see a farm occupied by aliens. In this area you find two Outsiders and one Elite Outsider; first ones are easy, but their commander can be challenging. First, weaken his shields with massive fire and then eliminate with a perfect shot (one headshot from a sniper rifle should be enough). Finish the fight quickly, because enemies will start using grenades.

Shield defends against additional damage from headshots. - Operation: Guardian - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughShield defends against additional damage from headshots.

When the first group is done, defeat the second one. It consists of two Drones, several Outsiders and one Elite Outsider. You should eliminate them in order listed above. Drones can heal allies, so they are your priority and Outsiders are relatively easy to kill, so you can finish them off quickly. Soften the leader and then eliminate with some strong weapon.

Puppet opens Secret Door. - Operation: Guardian - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughPuppet opens Secret Door.

When the battle ends, approach the barn's door. Move aside doll, which is on the cupboard what opens the secret passage. It's shown on the screen above.

Someone nice left schematic on the top of computer. - Operation: Guardian - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSomeone nice left schematic on the top of computer.

When you enter the room, approach the main computer. You find Schematic which slows down bleeding. When you get it, launch the rocket system (press and hold interaction key) and prepare for a surprise: you have just armed the nuclear warhead instead of disarming it! s

Silacoids are dangerous only for the short range. - Operation: Guardian - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSilacoids are dangerous only for the short range.

Go out through the opposite door and upstairs. Eliminate two Silacoids which will attack Carter and his squad nearby the next shed (one series should be enough). Pick up ammo from box next to the tractor and go forward until you reach another group of aliens.

Muton is the toughest enemy in this encounter. - Operation: Guardian - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughMuton is the toughest enemy in this encounter.

Besides few Outsiders you'll have to kill also one Elite Outsider. The latter one can be annoyed by commandos' Taunt and then quickly eliminated. But when you kill most of enemies, a Muton will arrive. He is challenging during fight for a short distance and you should keep him at bay. You should make use of grenades, mines (engineer stuff) and commandos' Pulse Wave. Recon can deal heavy damage with Critical Strike, but remember that only cooperation of whole squad will give you win.

Collect supplies (on left you find two grenades and ammo) and move on - Operation: Guardian - Walkthrough - The Bureau: XCOM Declassified - Game Guide and Walkthrough

Collect supplies (on left you find two grenades and ammo) and move on. Killed Muton should have dropped Scatter Laser which you can pick up if you run out of conventional bullets. After all go to the big shed in front of you and - like previous time - move aside a doll. When you get into control room, search soldiers and then launch computer. This time it won't work also.

Serious snipers. - Operation: Guardian - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSerious snipers.

Exit the room and read letter from the shelf on the left. Move forward and prepare for battle: you run into a group of Outsiders, supported by one Elite Outsider and two Rocket Snipers. The last ones are extremely dangerous. Their missiles can throw you out from behind a cover and kill at once. That's why you should focus at them always. The easiest way to kill them is to use a sniper weapon or Critical Strike (luckily, they're not that tough).Then, you can eliminate remaining enemies like in previous battles.

Better hide when Sectopod arrives. - Operation: Guardian - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughBetter hide when Sectopod arrives.

Collect all ammo you can: in a moment, you begin extremely difficult battle. When you only approach the alien device, more Outsiders, Elite Outsiders, single Shield Commander and finally also a Sectopod and two Drones will arrive. There is no one good plan for this battle: first of all, you have to use abilities, heal and save ammo. The most important is to eliminate quickly weaker enemies and Drones before they repair Sectopod.

When the glass breaks, you can kill the pilot. - Operation: Guardian - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughWhen the glass breaks, you can kill the pilot.

Shield Commander is your primary target: if you let him live, he shields Drones which will protect Sectopod. The last one is rather easy to eliminate when you break its front armor (then it's enough to fire at pilot's head). If you run out of ammo during this encounter, approach one of killed Outsiders - some of them leave Laser SMG with perfect fire rate and medium fire power.

Warhead will wait for you. - Operation: Guardian - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughWarhead will wait for you.

When the battle ends, go through the gate and enter the shed with the last one computer. When Barnes gives you coordinates, reprogram system (hold and press E). Congratulations, you have just saved millions of beings!

Remark! Name of this paragraph is identical like one of the previous ones. It's not a mistake, it's a consequence of the game's structure (saves are preserved with particular names). Wanting to describe the game faithfully, we couldn't change the game's setting. Apologies for this little confusion.

Things have changed in the Bureau. - Base Visit II (2) - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThings have changed in the Bureau.

When you return from the previous mission (Guardian or Grifter) you obtain an access to further parts of the base and get few more targets. All collectibles described in Base Visit II are on its places but there are few more also in the new locations. But before you look for them, you should report Faulke' who can be find in engineer room. To get there, exit Operations and turn left following the corridor.

Carters boss works on few cases at once. - Base Visit II (2) - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughCarter's boss works on few cases at once.

Talk to the Faulke when you get to him. He gives you an extraordinary task: you have to interrogate Infiltrator, which you have captured. But before you do, look to the room on right. Inside you find an interesting note about a new Bureau's vehicle and recording of its first tests.

Documents, documents everywhere. - Base Visit II (2) - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughDocuments, documents everywhere.

Exit the room and go to the laboratorial part of the Bureau. There, you find a lot of notes and two more recordings. Their exact localization is included in the proper chapters, there are too many of them to describe it here.

You have to reach an Infiltrator, who is at the very end of laboratory, on right - Base Visit II (2) - Walkthrough - The Bureau: XCOM Declassified - Game Guide and Walkthrough

You have to reach an Inflitrator, who is at the very end of laboratory, on right. Notice, that you can talk earlier to doctor Dresner in his laboratory and then make an additional Investigation. When you make it (or ignore), you're ready for interrogation.

If you fire at the alien, you enrage Faulke. - Base Visit II (2) - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughIf you fire at the alien, you enrage Faulke.

During interrogation you can play easy (upper dialogue options) or aggressive (bottom dialogue options). Whatever you choose, you get information you need which is an instruction of infiltration the main alien base. But your approach will influence Infiltrator's and Faulke's attitude toward Carter - you'll impress both if you choose the average path (upper option, bottom option and then upper option again).

The choice is lesser than you can imagine. - Base Visit II (2) - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThe choice is lesser than you can imagine.

After interrogation, return to Faulke and then approach computer in Operations. There you get an access to few more missions.

Notice that Guardian and Grifer are secondary missions: you don't have to make them if you don't want to (but it's profitable). Notice also that you get an access to distract mission: Gearing Up, Recovering Leaders and Nanotechnology (the last one is available only when you completed Investigation Find Missing Silacoids!).

Remember also that you main goal is a mission Signal from Beyond which pushes the storyline further.

Doctor Dresner can be found in his laboratory. - Investigation: Find Missing Silacoid - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughDoctor Dresner can be found in his laboratory.

When you finish Guardian or Grifter and return to the Bureau, you get an access to new locations. When you finish talking with Faulke (look: Base Visit II part 2) go to the laboratory behind a disinfection zone. Go through the room with big container of Elerium and then look to the laboratory of doctor Dresner (on right). Meet the scientist and obtain a mission. He'll appear here only if you've met him earlier in the main laboratory room.

Just follow the trace. - Investigation: Find Missing Silacoid - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughJust follow the trace.

Two Silacoids run away from the laboratory and you have to find them. You can look up for traces in Focus mode (screen above). Follow the trace and you get to the disinfection room. There you'll be attacked by one of creatures. Kill it quickly.

There is always a bathroom in game with aliens. - Investigation: Find Missing Silacoid - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThere is always a bathroom in game with aliens.

Trace of the other alien takes you to the bathroom on left from Operations. When you get inside, Silacoid will escape to the ventilation shaft and Carter won't kill him. That means, that the investigation isn't over.

Silacoids explode in very spectacular way. - Investigation: Find Missing Silacoid - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSilacoids explode in very spectacular way.

Following the alien trace gives no result, he has split. Luckily, there is a way to get him into the trap. Enter the Operations and turn left, going upstairs on the first floor. Going through the door you notice room full of mucus. Reload and prepare for a battle: few Silacoids will attack a soldier who is hidden in the corner. This gives you an opportunity for fight.

Look also at the note lying on the desk.

Reward isnt typical but profitable. - Investigation: Find Missing Silacoid - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughReward isn't typical but profitable.

When the mission is done, return to doctor Dresner. He gives you a new distract mission: Nanotechnology. To choose it, return to Operations and use computer.

There is a sniper on right. - Operation: Grifter - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThere is a sniper on right.

When the mission begins, go forward and try to get as close to the enemy position as you can. On the farm you find several Sectoids, one Outsider and one Rocket Sniper (marked on the screen above with "X"). You should eliminate the sniper first, as he has the biggest fire power in this set (one shot from sniper rifle should be enough). Remaining enemies shouldn't be a problem, but this is - unfortunately - only a recon group. And you'll get to know that really quickly - when Carter eliminates all aliens, several more Outsiders and a Drone appear on the battlefield. Your priority is, of course, the flying thing, because it can heal allies. So get rid of him first and then eliminate the rest of dangers (mobility is a key, aliens have a lot of grenades!).

Enter of the Silacoid isnt subtle. - Operation: Grifter - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughEnter of the Silacoid isn't subtle.

When you kill all enemies and collect ammo (from the cars) head for the shed. Inside, turn left and enter the small room where you kill Silacoid. Notice also, that there are two types of weapon on the floor: shotgun and Laser Pistol. You can pick them up if you want.

The difficult part begins further on. - Operation: Grifter - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThe difficult part begins further on.

Go through the shed (killing another Silacoid on your way) and exit through the door on the backs. Look to the Resupply Station on the shore and go to the river. Follow its current and you get to the locations shown on the screen above. Jump down and kill two approaching Silacoids. Then, use a footbridge which was abandoned by those monsters. This takes you to the further part of the location.

Look for Schematics. - Operation: Grifter - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughLook for Schematics.

Go forward until you get to the ruined wagon. Look inside and pick up Gunner Pack Schematic, which decreases amount of obtained damage and increases capacity of clips. Then kill another Silacoid, who will try to attack you from behind.

Drones appear rather surprisingly. - Operation: Grifter - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughDrones appear rather surprisingly.

When you move on, you get in between trains. Here, you find three wandering Outsiders, which you can take down easily (they're not expecting an attack). When it's done, three Drones and few more Outsiders will get out from the wagon on right. Eliminate the first ones quickly with Critical Strike or with sea of bullets. Notice that Carter's squad mobility is very limited in here: there is a plenty of deadly mines around. If you have to avoid enemy grenades, shoot at the mine first and then try to tumble.

Killing Muton may take a while. - Operation: Grifter - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughKilling Muton may take a while.

When you go through the wagon from which Drones and Outsiders emerged, you'll notice artifact sought by the Bureau. Unfortunately, it will be stolen by the alien which cannot be stopped (he is immortal). What's left, is a powerful Muton on the battlefield. Use grenades, mines (if you have an engineer), Diversion (recon) and bullets to eliminate this threat. Probably, you'll use a majority of your supplies in this fight, but you can replenish it thanks to packs in the nearby wagons.

Forcing enemy to move through train is a perfect tactic. - Operation: Grifter - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughForcing enemy to move through train is a perfect tactic.

Notice, that enemy is supported by an Advanced Drone, who has nasty ability which lifts Carter's companions. Eliminate him first, otherwise the battle will last forever.

If this encounter is difficult, you can play game of a cat and mouse. Muton is so big, that he can't move between cartons on left. As he is forced to move every time through the wagon, he is an easy and not mobile target. Use it, setting up mines or throwing grenades.

Here comes your goal. - Operation: Grifter - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughHere comes your goal.

When the fight ends, go through the carrier in front of you and pick up artifact. In this moment the mission ends.

Its only a prologue to real carnage. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughIt's only a prologue to real carnage.

When the missions begins, go forward and jump over the barricade. Run up to cover made by police and kill three enemies- an Outsider and two Sectoids. When enemies are dead, you'll see far away a Drop Pod, from which several more Outsiders will run out. Move between covers and avoid grenades killing enemies. This shouldn't be difficult, but watch out for Rocket Sniper, who will appear on right.

Getting too close to enemy wont end up well. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughGetting too close to enemy won't end up well.

When you defeat the second assault group, the third one emerges on right (parking lot). It consists of several Sectoids and Outsiders, supported by single Elite Outsider. You'll use lot of ammo surely, so collect it currently; between vehicles and covers you can find a whole store of weapons and bullets. Kill enemies how you like, using all possible abilities (especially Diversion, dragging enemies out from Carter, is useful). When you fight an Elite unit, destroy its shield (with some rapid firing weapon) and then finish off with something (like Critical Strike or sniper rifle).

An alien? Here? - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAn alien? Here?

Enter the car showroom on left side of parking lot and look around. On the counter you find and in the room on right you can find notes. Move forward in corridor - remember to turn left and enter a small room. You find there some interesting recordings to listen.

1 - button, 2 - schematics. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and Walkthrough1 - button, 2 - schematics.

Move forward, going through the room with cars. When you get next to the exit, turn around about 180 degrees. On the lift you can see a useful schematics. So, lower the lift using a button on right (screen above) and pick up schematics. This one increases range of abilities and amount of damage dealt. What is more, it enhances also character's defence.

They come to the rescue. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThey come to the rescue.

Move forward until cut scene with sieged agent DaSilva triggers. Help him fight aliens: between you is a small squad of Sectoids and Outsiders. Don't use special ability of DaSilva (explosives detonation) as you will have a better opportunity for it in a while.

Without DaSilvas traps, you wont win it. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughWithout DaSilva's traps, you won't win it.

When you talk with infected DaSilva, new enemies will appear on the battlefield- Outsiders, Sectoids, Silacoids, and even a Laser Turret and a Shield Commander. With such an amount of enemies, you have almost no chance so you have to play dirty. When enemies approach any of DaSilva's Traps, marked with blue in the Focus mode, trigger explosives in the selected area (screen above). This eliminates most of aliens and you can take care about the rest of them in ordinary way. Doing this, use special abilities of your squad like Critical Strike, Diversion (recon), Taunt, Pulse Wave (commandos), Disrupt (support) and Carter's abilities (especially Heal, Lift and Silacoid).

Muton is problematic, as always. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughMuton is problematic, as always.

When you kill all enemies, the last one arrives: powerful Muton. Try to lure him in between traps (using Diversion, or squad members) and then blow out with DaSilva's ability. If it's not enough, fire at him and throw grenades. Every effective solution is a good one.

When you choose the lower option, DaSilva dies! - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughWhen you choose the lower option, DaSilva dies!

When the battle ends, look around. On the parking lot you find plenty of weapons, grenades and ammo. When you pick those things up, enter the building where agent DaSilva is hiding. Read notes from one of rooms and then listen to the recording lying on one of desks. Then, meet with an agent and talk about the current situation. During this dialogue, you can make a storyline choice: upper option (screen above) let you take infected DaSilva to the Bureau, where scientists will take care of him. On the other hand, if you let him blow himself up with aliens inside of him (bottom option), you'll never see him again. Choice is your.

Resupply Stations give you a moment of rest. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughResupply Stations give you a moment of rest.

Look inside DaSilva's bedroom (on the left) before you leave the hideout. You find there interesting documents. You can also notice a photo of your goal, attached to the kitchen wall. Look closely at that.

When the collectibles are done, go out. Carter and his squad can use Resupply Station, in which you can swap weapons and resupply ammo. Use it wisely, because further part of this mission is a real challenge.

Turning left, you get more resources and collectibles. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughTurning left, you get more resources and collectibles.

Turn right and approach a small puddle. Next to it, you should notice a tombstone and an attached note. Read it and move forward. When the terraforming machines appear, turn left and go to the locations shown on the screen above. Turn left and approach the body of the child lying under the treehouse. Next to it, you find another note. Then, turn back and head for alien's computer, killing a Sectoid on your way. On the alien device you find Shield Disruptor Pack, which increases damage dealt to enemy shields.

Bulletproof balloons! - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughBulletproof balloons!

Move forward and prepare for a battle. At the patio decorated with balloons you find several Sectoids supported by Outsiders. During this fight don't fire at balloons, as they are bulletproof and prevent enemies from being shot (sic!). When the first group of enemies bite the dust, defeat the second wave (consisting of the same aliens) and then move forward. In the buildings in front of you, there are several more Outsiders and one single Elite Outsider protected by Rocket Sniper. The last one listed should be killed at the beginning, because he is the most dangerous one.

One of the most powerful weapons in the game. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughOne of the most powerful weapons in the game.

Enter the alien building and pick up Blaster Launcher and its missiles. This powerful weapons plays as bazooka and will be needed later on. For the time being, try not to overuse it and save its missiles.

Bureau agents die with class. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughBureau agents die with class.

Move on getting to an edge. Eliminate few first aliens and prepare for an explosion. DaSilva's car will cause a huge detonation which will kill the majority of aliens. Turn left and open passage to fortified enemy position. Go through another locations (killing one, single Silacoid) and get to the another parking lot, where you begin battle with numerous enemies.

This time Sectopod wont be a problem. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThis time Sectopod won't be a problem.

Move closer to enemies and wait for Outsiders to eliminate a Sectoid. Then eliminate all enemies and prepare for the second wave. You'll be flooded with the whole army of Outsiders and Sectoids to deal with. Fire at them, use abilities, change positions. When the Sectopod appears, immobilize him with Lift and then fire down with Blaster Launcher (if you're lucky, three series should be enough). After fight collect ammo as you'll need it later.

Meeting happens in bad conditions. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughMeeting happens in bad conditions.

Enter the supermar and find three notes in here - on the left (on the counter) and two more deep inside the building, on right. Then exit the building and meet doctor Weir. Next to him you find another letter (on yellow machine).

After conversation, enter the building on right and head for the corridor with big window, eliminating two Silacoids on your way. Turn left and read another note, left on the desk.

Silacoids are rather problematic - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSilacoids are rather problematic

In the further part of location you find Resupply Station which you can use. After that follow doctor Weir, until you get to the gate steering computer. Let the scientist take care of electronics and focus on eliminating Sectoids and Silacoids who will attack you from behind.

Your predecessors made it really far. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughYour predecessors made it really far.

Go through unlocked gate and move forward. You'll find nothing dangerous for a long time, so you can freely look around. Notice that in one of rooms (where doctor Weir tells you to look for an elevator) you can find human notes - they are behind barrels, next to the shotguns and pack of ammo.

Another Schematic. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAnother Schematic.

GO through teleport and then look around. Next to the Carter you find Armor Piercer Pack, which allows you to destroy armor very fast.

Turn right behind this bridge. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughTurn right behind this bridge.

Move forward and go through two bridges. In the big room turn right, ignoring the door in front of you. Enter the storehouse where you see a dead body and read two notes which he has left. Only after that go through door in front of you.

There is many of enemies and many yet to come. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThere is many of enemies and many yet to come.

Next part of location is a one big battlefield. You find plenty of Outsiders and Elite Outsiders, Shield Commander and (after a while) Laser Turret against you. During this fight use all abilities and terrain assets (there are explosive barrels here and there) The key thing is to weaken enemy shields: especially useful is support agent's ability called Disrupt. You can also lure enemies out from behind the cover with grenades what combines with summoning Silacoid (Carter) very well.

Try not to overuse Blaster Laser, because you'll need it later on.

Now you have to use your artillery. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughNow you have to use your artillery.

When the enemy army shrinks, Muton supported by three Drones appear. You have to eliminate Drones at the beginning or the battle will end up in failure. The best way to do so is to Critical Strike, which will eliminate them immediately. When it's done, use Blaster Laser and take down Muton.

If you have any weapon using normal (earth) ammo, replace it with alien guns: there are no conventional bullets in the further part of location.

Something has gone wrong. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSomething has gone wrong.

Move forward, pick up ammo and kill surprised Outsider and Sectoid. When you get to transponder (small, shining ball) use it. Unfortunately, the alien leader, Axis, will take over the main computer. Now you have to go through the corridors and get to Resupply Station. Using it, equip Carter with blaster launcher and something rapid firing. There is a boss ahead, you have to be prepared.

Titan is a powerful enemy. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughTitan is a powerful enemy.

Your last enemy in this location is Titan - flying sauces with outstanding fire power. He focuses beams of light at the target and fire destroying ray which annihilates everything on its way (including covers!). One hit with that and the agent is dead, so you have to constantly run around the location and avoid it. Remember that heroes behind containers don't get hurt, but when the shot is performed, their cover is destroyed.

Direct hit is a death. - Chapter III: Signal from Beyond - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughDirect hit is a death.

The key to win is rather simple: fire at Titan from Blaster Laser, constantly change your position and collect ammo from boxes. The weak spot of this devise is shining circle in its very middle, You should focus on firing right there.

During this fight very useful is Taunt which let you distract enemy. Also Diversion used by recon may be useful but the XCOM Laser Turrets (engineer) are rather bad choice.

Defeating Titan ends mission and you return to the base. Congratulations: you have defeated one of the most powerful enemies in the game!

Very unpleasant surprise. - Base Visit III - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughVery unpleasant surprise.

The good choice is The good choice is "Work with me".

Conversation with Russian isn't difficult. First made choice doesn't matter and in the second one you have to choose the middle one, offering the spy a cooperation (screen above). Don't give up during conversation (left option) because it fails the mission.

As a reward for interrogation, you get additional distract mission: The Russian.

When you land, go forward until you get to the soldiers bodies. Turn at them right and enter the park. You'll meet there three Outsiders, one Sectoid and leading Shield Commander. They shouldn't be challenging, especially that you'll find a Laser Pulse Rifle which deals huge damage for medium and long distance and has zoom, at the first wall. Using it is recommended, as you'll find a little of ammo packs while most of enemies use this rifle.

Its an ambush!. - Operation: Longsword - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughIt's an ambush!.

When the battle ends, go upstairs disarming mines. Up there you will fight three Silacoids and a single Outsider. Such a group shouldn't be a problem for you, so crush them. When they are dead, move on going through the next locations. Resupply ammo in a small army camp in front of you and then prepare for an encounter.

First encounter is just a prologue for the battle. - Operation: Longsword - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughFirst encounter is just a prologue for the battle.

You'll see three Outsiders - when you eliminate them, on right you'll see more incoming enemies, including a powerful Tech Commander, two Drones, stationary Turrets, Outsider and a Muton. Order of elimination should be like the order of lettering them above. The most important is to eliminate Tech unit very quickly as he can repair machines and become quite problematic. Muton is the smallest threat in here, as his weapon can't cause any serious harm from down there (hide a squad behind a cover). Very effective may be Plasma Field of commandos: enemies are placed on a small area, so you can easily burn them.

Schematics is on the right side of corridor. - Operation: Longsword - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSchematics is on the right side of corridor.

When the battle is over, go through the fortifications on left, resupply ammo and go through the alien defending spots. Then, enter the long corridor and pick up a schematics of Kinetic Acceleration Pack, which increases damage dealt to enemies without shields.

A lot of things happen in here. - Operation: Longsword - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughA lot of things happen in here.

When you enter the building, look for a Resupply Station and use it. Then, go through the gate and defeat a Shield Commander and two Sectoids (the best way is to lift the first one and fie down quickly). Then, go forward and prepare for an army of Sectoids and Silacoids, there will be a many of them. Enemies will try to drown you down with the same number of them, but don't get nervous: series from pulse rifle will stop the wave.

In case of need, you can use abilities like Fire Mission and Plasma Field like also useful Laser Turret.

Elite Sniper may kill your soldiers rapidly. - Operation: Longsword - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughElite Sniper may kill your soldiers rapidly.

When the battle ends, approach the big container in front of you and turn off the device. Then, go to the next room and kill immediately an Elite Sniper, who is on the opposite side of the room (Critical Strike plus two hits from sniper rifle should be enough for that). Then, eliminate two wandering Sectoids. When they are down, a huge Sectopod enters the battlefield.

Sectopod under the Fire Mission and Plasma Field will stand only few seconds.. - Operation: Longsword - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSectopod under the Fire Mission and Plasma Field will stand only few seconds..

At this stage of the game, this machine shouldn't be problematic: especially when you round it and use your abilities. When the moloch falls, two Drones appear, but they are nothing against you and your squad.

After this encounter go to the oppAxiste room and turn off alien factory - Operation: Longsword - Walkthrough - The Bureau: XCOM Declassified - Game Guide and Walkthrough

After this encounter go to the oppAxiste room and turn off alien factory. Doing so, you'll save hundreds of people and stop production of Silacoids.

Office? Its a standard hunter hut. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughOffice? It's a standard hunter hut.

When the mission begins, go forward until you get to the fireplace and find a hunter letter. Then follow the path until you get to the hunter hut (screen above). On the bench in front of it, you can find another collectible: page from the journal. Before moving on, turn left and find a small path between the scrubs. It leads to a small cave, inside of which you find a photo, another page from the journal and a schematics (decreases abilities cooldown but worsen weapon accuracy).

Treasure"Treasure" cave looks like that.

When you exit the cave, prepare for the fight: you run into a small group of aliens including an Outsider and two Drones. Eliminate them and return to the hut, passing it from the left. After a few moments you get to the puddle at which you find Outsider, Drone and Elite Outsider. They shouldn't occupy you for more than few quick seconds.

Lift an Elite alien and destroy Drones with Lift. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughLift an Elite alien and destroy Drones with Lift.

Kill enemies, go through the puddle and eliminate nearby mines. After that, you'll have a long walk, during which you find another page from journal on one of bridge supporting piles. When you get to the fisherman hut nearby the sea, prepare for three Drones and a Muton. Firstly eliminate the flying aliens, to prevent them from healing bigger monster. You can kill them with short series of rifles or using Critical Strike.

Muton isnt a threat. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughMuton ins't a threat.

Muton can be killed with Plasma Field (commandos), which can eliminate an enemy within few seconds. Good idea is also to summon a Silacoid (Carter) or use Fire Mission (recon). XCOM Laser Turret (engineer) will be also effective. f you run out of ammo, look at sides of this location where you can find boxes with bullets to laser weapons.

Plenty of weapons around, dont complain about it!. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughPlenty of weapons around, don't complain about it!.

Moving forward, search the piles of weapon (on one of shelves you can find Sticky Grenades). Then, approach the panel on left and, after talking with agent Weaver, order one of the squad members to hack the broken gate. Then prepare for a battle with the whole alien army. In the first wave, you'll fight against three Drones and a group of Sectoids (eliminate the healers first), and then several Outsiders. When the last one are dead, Sectopod will join the party. Rounding him won't be that easy (as you have only two agents). The optimal way to defeat him is to distract an enemy with ally Silacoid (Carter's ability) and firing at him constantly (preferably at its back, where the armor is weaker).

If you run out of bullets, move back to the gate. Just next to it you find a box with laser ammo.

Agent was caring about her brother, who is an author of the journal. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAgent was caring about her brother, who is an author of the journal.

When all enemies are down, go through the unlocked gate and enter the huge factory. When you get to agent Weaver, talk with here and go to onto the other side of the bridge (activate it first). In the following rooms you find a Resupply Station, which you can use.

Not the most useful pack, but still useful. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughNot the most useful pack, but still useful.

You get to the crossroads - turn right and look around in the scary room, where the experiments on humans take place. On the laboratory shelf on right you find schematics of Range Enhancer Pack, which increases an effective distance of all abilities. In the nearby corridor you find another page from the journal and when you approach it, two Outsiders to kill appear in the room.

Return to the crossroads and turn left.

Elimination of Phantoms takes few seconds. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughElimination of Phantoms takes few seconds.

In the big room you'll have a not easy battle with enemies. There are two Elite Snipers under the ceiling and two Phantoms walking on the floor, Elite Outsider and a standard Outsider. As the shooters are well hidden and are far away from you, you won't kill them that quickly. That's why focus on Phantoms - if you eliminate them quickly enough, they won't be able to use a camouflage (what saves you against being flanked). Then deal with Elite Outsider and Drone, which will appear in this very moment. At the very end, move a bit closer to Snipers.

Drones must be destroyed before they heal allies. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughDrones must be destroyed before they heal allies.

When the majority of enemies is dead, a small group of Outsiders and Sectoids will join the party. But your priority are snipers who have the biggest fire power in here. It's a good idea to lift and eliminate quickly one of them, dealing with the other one later, when being involved in fighting other aliens. You can pick up ammo from the box in the middle of the room, or from plasma rifles left by the enemies.

Surprise a Phantom from behind - its not that easy. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSurprise a Phantom from behind - it's not that easy.

It's not the last difficult encounter at this stage: behind a corridor you find another room where you find even stronger enemies. Firstly, get rid of a Phantom and Tech Commander - after that it should be relatively easy. What left are Sectoids who won't trouble you so much: because they know that Carter's entering to the laboratory, is an ambush.

Plasma Field crushes armor. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughPlasma Field crushes armor.

And indeed: when you kill few first enemies, a Muton and two Sectoids will appear behind you. You'll have to change your position a lot and weaken the big monster: useful may be Plasma Field, XCOM Laser Turret, Fire Mission and Ally Silacoid. And you have to be quick, because in some time three Drones will appear and immediately heal a Muton. If you didn't kill him before that, now focus on the flying things. Ammo may be resupplied at the pillar next to the entrance, at the computer panels in the end of arena.

Sad fate of Angela and her brother. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughSad fate of Angela and her brother.

When the battle ends, enter the room with agent Weaver and Pete's body. Plug him out or let Angela do it. Then return to the chamber where you fought and move left, passing a long corridor. When you get to the crossroads turn left: in the following rooms you find fragment of a weird book and Schematics (increases damage dealt to heavy wounded enemies). When it's done, return to the crossroads and choose the path on right. On your way, three Outsiders will attack you. Kill them freely.

Teamplay is a base of the success. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughTeamplay is a base of the success.

In the next room you find two Outsiders and one Elite Outsider, which should be quickly eliminated. When the encounter begins, a Tech Commander, supported by several Sectoids, Outsiders and Silacoids will run into this room. Luckily, agent Weaver will lend you a hand: use her abilities to eliminate enemies (begin from the Tech unit!). When it's done, look at the Plasma Sniper Rifle in the middle of the room: if you don't have a regular sniper rifle, this upgraded version will suit you. Equipped, go look for an Axis.

Computer which you have to turn off. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughComputer which you have to turn off.

You archenemy will be met further, behind a several corridors and empty rooms. When an alien sees Carter, he'll cloak himself with indestructible shield and summon several Sectoids and Outsiders. Eliminate the first wave of enemies and notice another danger - two Phantoms trying to round the squad and a Tech Commander creating a Turret. When it's done, enter the random room powering the shield of Axis and turn off a computer (screen above). You need to do it two more times to win!

Lure Mutons with Diversion and eliminate with area attacks. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughLure Mutons with Diversion and eliminate with area attacks.

When the first of shields is deactivated, more enemies will arrive on the battlefield: Phantoms, Outsiders, Drone and a Muton. Luckily, agent Weaver will support you once again and her deadly ability has a short cooldown. Eliminate all enemies and save ammo (which can be resupplied in rooms powering the shields of Axis) using all useful abilities. Don't hurry to turn off another computer - heal the squad and look for additional equipment (enemies will arrive in the moment of deactivation).

Axis is a tough enemy - he avoids area attacks easily. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAxis is a tough enemy - he avoids area attacks easily.

Defeat all aliens which appear when you turn off the second computers (Elite Sniper, Phantom, Outsiders and a bit later also a Muton - eliminate them in this order). and then approach the third device. Make sure, you have enough ammo and you have regenerated all the abilities, you can wait for it, there is no hurry. When you're ready, turn off the last of the computers: now you'll face Axis.

Agent Weaver is an ace up your sleeve. - Chapter IV: Not of This Earth - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAgent Weaver is an ace up your sleeve.

Axis has strong shields, can teleport, fires accurately and deadly and, also, has a powerful area attack dealing huge damage to the whole squad. During fighting him, you shouldn't use abilities affecting small area because this alien will avoid them easily grenades also (unless he has already use teleportation - it has a several seconds of cooldown). The better idea is to summon Silacoid, supported by a Drone (Carter's abilities) and firing at him constantly by agent Weaver. Simultaneously, you can't forget about healing the squad and keeping an alien at bay.

When the Axis is down, the mission is completed. You can return to the base.

Investigation Test Flight is a simple logic riddle. When you talk to Barnes in Engineering, move to the Avenger via stairs on left. Launch the Focus mode and look for three leaks. To find them, you have to aim at highlighted placed and use a scanner (in PC version it's made by F button).

When you scan the system, a schematics will appear. - Investigation: Test Flight - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughWhen you scan the system, a schematics will appear.

Mission begins with a hot shooting. - Operation: Hawkeye - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughMission begins with a hot shooting.

When you get to the place, you'll be fired at by a group of Sectoids. Try to eliminate them only with abilities, as you'll find a little of ammo in this level. And you'll need it very, very much.

When you kill first few enemies, they'll fall back and get reinforcements. Also those one should be defeated without using precious bullets. Otherwise, you'll lose the upcoming encounter.

One of the most difficult battles in the game. - Operation: Hawkeye - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughOne of the most difficult battles in the game.

When you get to another fortification, a Drop Pod with several more Outsiders and a Shield Commander (focus on him) falls from the sky. This time save both bullets and abilities, because when the last one alien dies, an Elite Muton will enter the battlefield.

Deadly jump of Elite Muton. - Operation: Hawkeye - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughDeadly jump of Elite Muton.

Mutons are powerful enemies, but their Elite leaders are far more challenging. They have not only more HP, better armor and more effective weapons but also several deadly abilities. First of them is a long jump, which causes a destroying shock wave when he hits the ground. Another one is a possibility of creating Plasma Field: the same like the commandos can. If it's not enough, Elite Muton deals also huge damage at short distance.

And now a look at the Muton creating the Plasma Field - be careful! - Operation: Hawkeye - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAnd now a look at the Muton creating the Plasma Field - be careful!

A tactic use for encountering normal Mutons (stopping an enemy and usage of area attacks) won't work because an enemy is too mobile.

You do so, because snipers has the smallest HP, so they're easiest to kill. Remaining enemies are much more challenging. You can Lift Muton or summon Drone and an ally Silacoid - this will make the elimination easier. If you have a Lightning Cannon, use it against the strongest enemy.

One of the most difficult battles in the game - prepare well! - Chapter VII: The Day the Sky Fell - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughOne of the most difficult battles in the game - prepare well!

When you eliminate most of enemies, more aliens will appear: two Elite Phantoms, one Tech Commander, one Outsider and a Laser Turret. Finish of the Tech first and then the remaining ones - order has no meaning. But don't hurry and don't go too much forward, because when you get to the end of the room, another deadly group will join the battle: two Elite Mutons and four Elite Phantoms. So before you fight them, collect ammo from both side of the battlefield and from its bottom level.

Muton, who is at the bottom, can be easily killed. - Chapter VII: The Day the Sky Fell - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughMuton, who is at the bottom, can be easily killed.

You have to play this battle wisely. First of all: immobilize both Mutons - one with Lift, and the other one using Mind Control. Then eliminate the enemy Turret and concentrate on Phantoms. When Mutons get out of the trap, summon a Drone and Silacoid to take care about one of them. Then round the other one and kill with all weapons and abilities you will consider useful. When there is only one enemy left, regroup and collect ammo. Regenerate abilities and finish off the enemy.

Earlier decision has a consequence. - Chapter VII: The Day the Sky Fell - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughEarlier decision has a consequence.

Remark! If you have already been in "rooms on right", you'll find a body of your companion.

Move forward and use Resupply Station at the teleport. Then use a terminal in the middle of platform and teleport further.

Right door

Battle isnt easy, but you should win. - Chapter VII: The Day the Sky Fell - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughBattle isn't easy, but you should win.

Moving forward, kill two Outsiders and enter the room where your companion is defending. Encounter won't be easy, because there is a single Minion Commander, two Drones (one of them is Advanced), one Elite Sniper and three Elite Outsiders. Eliminate them.

First Sectopod is only a recon. - Chapter VII: The Day the Sky Fell - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughFirst Sectopod is only a recon.

When you finish off the aliens, go down and collect ammo. Then, approach the weird container with black fluid: after a while Sectopod goes out of it. Kill him without using too many abilities and firing from Lightning Cannon, because more aliens will arrive. In a moment you'll be fighting three Elite Outsiders, Psion Commander, two Advanced Drones and a Heavy Sectopod. First of all, Lift the Commander and eliminate the flying things - only then finish off the Lifted alien. Also, take over the Sectopod with Mind Control gaining a precious ally.

You have decided who has to die. - Chapter VII: The Day the Sky Fell - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughYou have decided who has to die.

Remark! If you have already been in "rooms on right", you'll find a body of your companion.

Approach the terminal and launch it. If you want, you can also use the Resupply Station in the corner. Then go through the teleport.

The Final

Decision is yours. - Chapter VII: The Day the Sky Fell - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughDecision is yours.

When you open all three mechanism you will be a witness of Carter's rebellion. After a short cut scene and a conversation you can make a decision: kill or spare the agent. To do the first thing fire at him, to do the other move through the door behind you. Your choice won't affect the further events, because the game ending is always the same.

The Final is coming! - Chapter VII: The Day the Sky Fell - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThe Final is coming!

After that, you get into a big, long corridor, at which's end there is a terminal with an elevator. Ride upstairs and go to the further part of location (you'll be tempted by the enemy on your way there). After a long walk here, you get to the room full of enemies. There are: Tech Commander, three Elite Snipers and three Elite Phantoms. Finish off the Commander first, so he won't set up a Laser Turret. Then kill Snipers and Phantoms at the very end. If you run out of ammo, look into the side corridors of the location, where you can find two ammo boxes. Try to replenish ammo using the weapon you find, because you won't find a lot of supplies and this battle is long and challenging.

Advanced Drones are very onerous. - Chapter VII: The Day the Sky Fell - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughAdvanced Drones are very onerous.

When most of aliens is dead, two Scouts will join the battle and then two more. Don't get round and eliminate your enemies one after another (they can avoid area attacks easily). But it's not an end - when you finish off the Scouts four Drones (two Advanced) will appear. You have to destroy them ASAP because in a while another assault squad will arrive on the battlefield: two Elite Outsiders, three Elite Phantoms and a Minion Commander. Kill the Commander first so he won't be able to summon allies. Prepare also that after a while more Elite Outsiders and Elite Phantoms will be joining the battle.

The last, most difficult, wave. - Chapter VII: The Day the Sky Fell - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughThe last, most difficult, wave.

It's only a warm-up. When two Advanced and two regular Drones appear, regroup in the middle and collect ammo using the boxes from the corners and in the center of the location (don't use all of them yet!). When you destroy the flying machines, the last wave will appear on the battlefield: two Tech Commander, two Minion Commander, two Elite Mutons and a group of Elite Outsiders and Elite Phantoms. Firstly defeat Commanders, then infantry and only at the end the muscles.

Game finishes with a spectacular win. - Chapter VII: The Day the Sky Fell - Walkthrough - The Bureau: XCOM Declassified - Game Guide and WalkthroughGame finishes with a spectacular win.

When you finish the battle approach the computer in front of you and turn off the shields. Go through the gates and watch the cut scene. It's the end of the game, congratulations!

When you complete few first storyline mission, you get an access to so called Distractions. Carter doesn't take part in that, but he sends his companions (like in Assassin's Creed series). Agent assignment is made via computer in Operations, like in case of normal missions.

This is Distraction window. - Distraction - The Bureau: XCOM Declassified - Game Guide and WalkthroughThis is Distraction window.

Every Distraction has a difficulty level, it decides about how many agents you have to send there to complete mission (and for Carter to obtain a reward). In those operations freshly recruited agents and veterans can take part but if they do, they will be unavailable for Carter's missions. Notice also that advanced heroes are much better than the newbies. For example: if the Mission Complexity is 5, you can fulfill by sending 5 freshly recruited agents or one agent on level 5 (you can also send 2+3 or 2+2+1).

At the beginning you dont have a lot of options. - Distraction - The Bureau: XCOM Declassified - Game Guide and WalkthroughAt the beginning you don't have a lot of options.

When the mission ends, all agents which were participating in, gain a level. Remember, that the mission will be completed only when a sum of heroes' levels will be equal to the Mission Complexity. Otherwise, the mission will fail and you get nothing in return.

Below you can find a table with all Distractions.
