Mass Effect 3: Leviathan Game Guide & Walkthrough

This game guide for Mass Effect 3: Leviathan is a compendium, and it contains a thorough description of challenges offered by this DLC, alongside with necessary and supplementary information required for its completion. The contents of the guide are as follows:

• a detailed solution to the new mission;
• description of locations;
• description of conversations with encountered NPCs;
• hints on fighting enemies;
• description of localization of rare items (upgrades, new weapons, datapads etc.);
• the description of the possible choices, and differences in gameplay resultant from decisions made during the gameplay;
• rewards for completed missions;
• new upgrades war assets and weapons listing;
• How to use this guide?

At the beginning of the description of individual parts of the missions, you can find information concerning the questgiver, and how to unlock it. At the end of the descriptions, you can find notes concerning the next mission. In practice, this means that individual chapters of the guide correspond to the sequence of missions in the main mission.

For your convenience, the guide has been divided into chapters corresponding to the individual locations visited during the gameplay. Since there are no side missions in the DLC, the layout of this guide is linear - same as the main mission offered by the DLC.

To prevent any item to be missed by the player, each chapter features a part named "treasures" that describes all items and upgrades available in a given location. Thanks to that, the contents of the DLC will be more accessible.

Colour coding

The guide has been colour-coded in the following manner:

Red corresponds to the names over the missions.

Blue corresponds to the visited locations.

Green corresponds to the items you find, both the ones that you cannot take with you, as well as those that the game allows you only to examine (e.g. a palmtop, a terminal).

Orange corresponds to the war assets that you acquire throughout the game, intel and experience points. In reference to the latter one, the acronym EXP has been used. For example [800 EXP] means that: an activity you can when as much as 800 experience points.

When to perform the mission offered in the DLC?

You gain access to the additional contents automatically, after the completion of the Priority: Palaven mission. After you return to Normandy SR-2 approach your personal terminal and receive the message from Admiral Hackett. That is when a new mission appears in your journal- Citadel: Doctor Bryson. This is the only mission offered by the Leviathan DLC.

If you've decided to perform the mission right after you come back from Palaven, before setting out the need to need to meet EDI on the Normandy deck 3. Regardless of the chosen dialogue options, the new character will join up with your team. The artificial intelligence will aid you during the performance of the mission - it's only the artificial intelligence that may help you handle some of the tasks. When it takes its place next to Joker, you'll be able to set out to the Citadel, where you can find the man you are looking for (see: Doctor Bryson's Lab I).

You don't need to take up the mission right after you escape from Palaven - it will be available in your terminal throughout the considerable part of your play. Remember, however, that you should perform it before Priority: Cerberus' Headquarters -otherwise you won't be able to access several key locations and the mission will fail!

Quest giver: Adm. Hackett [Normandy SR-2: personal terminal]

Means of unlocking the quest: Receive an urgent message from Admiral Hackett on your personal terminal.

After you read the orders from Admiral Hackett, go to the Citadel. During docking, location selection screen will appear-Dr. Bryson is to be found in his Lab (see the screen below). It is an entirely separate location which you can reach only during docking (you cannot go there or from the Citadel itself). You will be accompanied in your journey by EDI, who will join you automatically.

After you arrive, talk to the scientist. Unfortunately during the dialogue you won't get to know anything useful, and the doctor himself will die shot by his assistant. That is when two sequences will appear, allowing you to choose between an amicable or hostile gaming style. The former allows you to overpower the assassin (Idealist path), whereas the latter will allow you to hear the enemy firmly (Renegade path). Regardless of how you choose to behave, this will not influence the course of action-you also won't acquire any additional reputation points. Your choice this is of no significance whatsoever.

Your task is to find anything to allow you to trace Leviathan - a mysterious creature discovered by Dr. Bryson. The search is neither long nor problematic-after the cutscene you'll see in front of you an audio journal that you should play now. After the recording ends, you will be granted [100 EXP] and you need to open the galaxy map that is located in the lab's main chamber. After using it you will you will be rewarded with [100 EXP] and you will be given a new mission - to find any clues that would help you determine Bryson's co-workers' whereabouts.

To the right of the map you can find Prothean Artifact hidden behind a huge pane of glass. Use it to apply the first of the search filters to the map, which will allow you to find the doctor's co-workers. This way you will be awarded [60 EXP]. In the corner of the room, between the doors, you should see a desk with two computers on it. Start them to apply another filter - this time marking blackout crimes. After that, you will be awarded another [60 EXP].

Move to another room. To your right hand side there is a doctor's daughter's drawing on the desktop (irrelevant) and two datapads. Use them to apply Raknii movement filter to the map. Thanks to that you will be awarded another [60 EXP].

Go to the right corner of the chamber to switch on the display and see the scheme of alien sightings. Use it to get another filter and [60 EXP].

Turn left and have a look at the meteorite and next to the optical instrument. This way you will be given another one of filters that you are after (concerning element zero) and [60 EXP] the last one of the traces is a bit problematic. Approach of the desk next to the remains of the Sovereign and use the two datapads that you find there. You'll need the special password for one of them. Climb the stairs to the doctor's bedroom and find there a drawing with the password on it. Then, go to the encrypted datapad. At this moment you will be awarded [60 EXP], and the last one of the filters that shows the Reapers' movements.

Equipped with all six clues, approach the map and apply individual search filters. Some of them do not give you any important information - they are just dead ends. To determine the exact whereabouts of your destination - i.e. Dr. Garneau, with whom Bryson worked - you need to turn on the following filters: the element zero, the Reapers, and the alien sightings. Only in this combination can they lead you to the right system, but you can also go out and find them on your own by flying into various parts of the galaxy. This, however, is a time-consuming and pointless process, and additionally, if you manage to narrow down the scope of your search to one area only, you will be rewarded with [280 EXP]. That is why pinpointing the exact system is definitely more profitable an option.

If you want to you may leave the Lab-to do this use the quick transport vehicle that is parked outdoors. Before you do, however, search around the place-you can find a number of useful items here.

Rewards for completing the quest:

unlocking a new area: Mahavid in Caleston Rift

Treasures

Cranial Trauma System I (pistol) - outside of the lab, in the balcony's corner.

High Velocity Barrel I (SMG) - on the ground next to the containers, opposite your vehicle.

Ultralight Materials I (pistol) - behind the tree on the balcony.

Recoil System I (SMG) - in the Lab next to the meteorite.

Questgiver: none

Means of unlocking the quest: determine doctor Garneau's whereabouts during your stay in Dr. Bryson's laboratory in the Citadel.

After you leave the Citadel, go to the Caleston Rift and go to the Aysur subsystem. The asteroid you are searching for is not visible on the map of the system using the scanner installed on Normandy and find Mahavid. You will find it in the meteorite belt that surrounds the entire area. Then go to the planetoid.

After you get there go straight ahead at and take the lift down to the lower level of the building. Prepare yourself for a fight with Reaper spawns - up ahead you will see a brute and two marauders. There is quite a long distance between you and them, so you should have no problems with exterminating them. After a moment yet another brute will turn the corner, but you will have no problems defeating him. If you've lost too much ammo during the combat, there is a small deposit of it in the right side part of the room right next to the balustrade.

Climb the stairs to the next level of the building. Collect ammo and the medkit in the corner [100 exp]. Next go to the passworded door (Shepard's omnikey should have no problem dealing with it) and watch the cutscene. People you are about to meet are trifle odd, but you do not need to worry about them-they will not harm you. Do not expect them, however, to help you-none of them has ever heard about Dr. Garneau, and the lift to the further part of the facility has been damaged. In practical terms this means that you may have a look around the area and find two datapads: to the right [1250 credits] and at the left hand side of the room [2500 credits].

After you reach the broken door at the end of the room, you'll be given a new mission: to repair the lift. To do so, approach the terminal of the repair drone that you will find to the left and some of the robot. When you see that pulsating sphere, direct it to the broken installation. Once the obstacle is removed you will be awarded [10 EXP], and a new area will open up.

Pass through the door and start the lift. After you reach the higher level, have a look around the corridor-to your the left will find an abandoned datapad [1250 credits]. Regardless of the door you choose, you will enter the mineral works. In the corner of the room leading up to the crew's quarters find a terminal that will give you [1250 credits]. On the table with flowers on it you will find yet another datapad [1250 credits].

Go right and past the security terminal. Open the passworded door and enter the room where there is a secret conference being held. On the rest of the rest of the couch will find another datapad [1250 credits]. Go through the door on the right and make yourself comfortable in a small watch room. Ignore the soldier standing there and have a look at the datapad [2500 credits] in the armchair. Thanks to the datapad you will learn the facility employee's ID and you'll get access to the crew's quarters. Go there and take ultralight materials II (pistol). The datapads that you find there will not contribute in any way to your quest, so you can ignore them.

Make your way back to the conference room and break the password to the locker. After you enter it turn your attention to the datapad [2500 credits] lying to the right. Thanks to the datapad you'll learn the password to the security terminal and you'll be rewarded with [10 EXP]. In the very same room you can find high velocity barrel II (SMG). After you loot the location for all the valuable items, leave.

Go to the security terminal. Use it and you will be given a pass to the medical station and [250 EXP]. Pass through the conference room once again and open the door to the hospital that has been locked thus far. Once inside, grab the medkit [100 exp] and have a look into the darkroom. At this moment you'll see a cutscene concluding in the escape of the possessed Dr Garneau [200 exp].

Start chasing the man. Open the locked door with a password and climb up the ladder. You will find yourself standing outside of the base. Get ready to put up a battle with several husks-keep them at a distance and use the team power. Next jump over a hole between levels and enter the pedestal. Collect the recoil system II (SMG) and jump over the barrier.

As you go further eliminate two husks and get ready for a tough combat with marauders and ravagers. There is a whole lot of them, so you should need to pass between covers and successively eliminate next enemies. When the second wave comes, expect even more enemies, and in the third one - two bloodthirsty banshees. Keep them at a distance and keep firing your guns at them. Avoid the their projectiles - they are poisonous, and therefore very dangerous. When you deal with them, go to the door at the end of the location. Kill the ravager and two husks. Then have a look around the room-apart from the ammo you can find there a medical kit [100 exp] and Cranial Trauma System II (pistol). When you try to open the start door, it will turn out that someone disconnected them from the energy supply. You will be given [400 EXP] and a new mission- to transport the repair drone to the damaged generators.

Do not move far away from the drone - when you are outside of the reach of its radiation, the mechanism will be permanently damaged and you will fail the mission. That is why you need to follow it, avoid the enemies and fire your gun and them at the same time. It isn't easy, because hordes of marauders, husks and ravagers renew s all the time. They will stop only after both of the damaged units are repaired. If you've waited for too long, you should expect a fight with a banshee-that's no jokes anymore. That is why you should attempt to complete this part of your mission as soon as possible [400 exp]. If the combat proves troublesome you can always use Reaper Blackstar, which you can find in the corner of the room-you can kill any enemy with just one round.

Make it back to the door that has been blocked so far and walk through it [200 exp]. Watch the cut scene in which you can learn the truth about Garneau and the facility you are in. Talk to the survivors and go back to Normandy. You are up for another investigation at Dr. Bryson's laboratory.

Means of unlocking the quest: solve Dr. Garneau's riddle

After you come back from Mahavid make your way to Dr. Bryson's lab in the Citadel. Watch the cut scene in which EDI secures Leviathan's artifact. Thanks to this you will be able to resume your investigations securely. In this location you can find several items but it's only one of them is of importance-the datapad in the doctor's bedroom upstairs. Use it to play the scientist's daughter's recording. That is when you will receive [360 exp] and a new mission- find any hints that would allow you to find the girl.

Go downstairs and approach the palmtop on the desk. This way you will get to know about the ship that Ann Bryson travelled on. Use the computer console located next to the sovereigns fragment. Start the computer and choose the ship named Icarus. Thanks to that he you will narrow down your search and you'll be given [50 exp].

Go to the room with the galaxy map. Inside the desk with a husk's head on it you should see a small drawer. Use it to gain a palmtop with the access code. With the code on you, approach the locker you can see in the corner of the room. Open it and examine everything that you find inside. This way you can learn that the planet Ann Bryson is trying to get to is dry and uncivilized. Thanks to this discovery you'll gain [50 exp], and when you search the locker for even longer you will find omni-blade I (assault rifle).

Armed with these two pieces of information you can approach the galaxy map and apply appropriate filters to it. Your experience will be doubled by [50 exp], and the daughter's location will no longer be the secret. It is enough to reach the Pylos Nebula and search for the Namakli planet in the Zaherin system. That is where you will find the person that you are after.

If you want to, you can give up following the traces and search for the researcher on your own among the systems of the Pylos Nebula. However, despite you'll waste a lot of time and you will gain no additional experience points this way, so there is a worse way out. It is better to search around the laboratory and find both hints.

Rewards for completing the quest:

Unlocking the Area: Namakli in Pylos Nebula (Zaherin System)

Treasures

Omni-blade (assault rifle) the locker next to the galaxy map (the access key is to be found in the drawer of the desk in the same room).

Quest giver: none

Means of unlocking the quest: determine Ann Bryson's whereabouts while in Bryson's lab in the Citadel.

When you go to Namakli, you need to get prepared for a tough fight. The planet has been seized by readers, and Dr. Bryson got caught right in the middle of the invasion. That is why, as soon as you land on the enemy territory, grab the best weapon you have and pick the most effective of your powers- it's not going to be easy.

As soon as you disembark, start shooting at the husks that will charge at you. The reapers that keep flying around may be completely ignored - the creatures fire only at the scripted locations and not at you in particular. In themselves they are immortal, and that is why fighting them is useless. Go straight ahead towards the lift. When a fragment of a building comes down into the void, jump over to the next segment in front, towards the ladder. Climb down the ladder, and up another one. Jump into the lift and proceed.

Proceed forward until you reach the room with a hole in the ceiling. Jump down and continue forward. Kill two cannibals lurking in a further part of the complex and reach their positions. Three new enemies will arrive, but you can eliminate them with explosives that you can find in the vicinity. After the building and find the AT-12 Raider shotgun (next to the dead body of the engineer near the door) and the High Velocity Barrel III (SMG) upgrade.

Leave the room and climb up the ladder to the roof. Kill the husk running up to you-it will appear close enough for a simple blow in close quarters to be the most effective. Jump into the rocky footbridge and start the lift with a special panel. Three husks will appear, you can take them out from the distance. Before the lift comes, you are up for an easy battle with a banshee. You may eliminate it by means of explosive barrels located in between you and the creature. When the banshee goes down, proceed forward.

Keep going until you reach another lift control panel started to see the mechanism go to lockout. Ann will open an alternative way through for you to use. Enter the room and collect Recoil System III (SMG). Leave through the door, jump over to the stairs and climb it. Take down the cannibals and ravagers that gathered in this area. Around you can find quite a few covers to hide behind so the fight should not be difficult. When you deal with them collect the data from the terminal [2500 credits].

On your way out of the building jump over the void and climb up the ladder to see another container. Kill the cannibal and collect the Medkit [100 exp]. Climb a cool the roof on the ladder and jump over several obstacles that have been put on your way. Kill one cannibal after another and climbing until you reach the rock you can walk on. You are up for a skirmish with several husks and a brute, but you can defeat them by shooting at the explosive barrels around.

When the platform collapses turn left and take cover. Kill off all of the cannibals, ravagers and marauders that you see ahead. There will also be a reaper that will appear around, which you can shoot down (it will be attacking you for some time but then it will fly away). Use the medkit [100 exp] and go forward. Eliminate two cannibals and pick up damaged equipment [2500 credits] in the corner of the location. Enter the container ahead of you and collect another Medkit [100 exp] and the data [5000 credits].

Go forward and meet up with Ann Bryson. See the cut scene and get prepared for a challenging battle. Up ahead of you there will appear an entire army of cannibals and marauders aided by a reaper. Your aim will be to kill the latter one. If you want to make it easier for yourself, you can aim only at the flying reaper-killing all the remaining monsters is not compulsory. After a few moments the shuttle will arrive, that you can escape on. It pays off, however, to kill each and every one of the enemies. This way you will be able to access the room at the end of the gap, where you can find the last of the medkits [100 exp] as well as data [2500 credits]. As soon as you enter the shuttle, this part of the mission will be completed. You should go to Dr. Bryson's laboratory to talk to his daughter.

Treasures:

Data I [2500 credits] - inside one of the rooms on the top level of the building behind the stairs leading to the broken lift.

Data II [5000credits] - in the room at the third lift control terminal.

Data III [2500 credits] - in the container and the evacuation shuttle.

Damaged equipment [2500 credits] -near the murals between buildings on your way to the broken lift.

High Velocity Barrel III (SMG)- next to the desk in the room in which found the AT-12 Raider shotgun.

Recoil System III (SMG)- the room next to the broken lift (Ann Bryson will open the door for you).

 

AT-12 Raider - next to the engineer's dead body next to the entrance to the building with lurking cannibals.

Medkit I [100 exp] - in the container with one cannibal on the path leading up to the broken lift.

Medkit II [100 exp] - on the platform patrolled by cannibals, marauder and a reaper.

Medical kit III [100 exp] - in the room at the third lift control panel.

Medkit IV [100 EXP] -in the container near the evacuation shuttle.

Means of unlocking the quest: complete the mission on Namakli

Return to the Citadel. When you'll land in the laboratory, you will see the cut scene. Watch it and then go down to talk to Ann Bryson [60 exp]. Total correct for the second time to acquire more information [60 exp]. Follow her to the bedroom with the map. You will meet James there that you can have a conversation with (this will not influence the mission in any way).

Talk to Ann Bryson once again to find out that the artifact kept in the laboratory is in fact the Leviathan's relay [60 exp]. When you talk to her once again the woman will become processed by the beast. James will want to stop the process, but you can stop him by choosing the egoist option. To break the connection you'll receive [340 EXP] and 2 skill points and Leviathan's hideout in the Sigurd's Cradle will remain secret, and you will have to scan through the whole system. If you stopped Leviathan during the second time you'll receive [340 exp] and 2 egoist points and Leviathan's whereabouts will be narrowed down to two systems. The last one of the possibilities, which is interminable connection, will result in [340 EXP] and 7 egoist points. In such a situation, the monster will be exposed. Go to the Sigurd's Cradle in order to find 2181 Despoina in the Psi Tophet system - the final destination for your search.

Note! If you stop Dr. Bryson is possession at once, right after the mission is completed, you will be rewarded with [20 war assets] after you finish the task.

Rewards for completing the quest:

unlocking of the area 2181 Despoina in the Sigurd's Cradle (Psi Tophet system)

Quest giver: none

Means of unlocking: determine Leviathan's whereabouts.

This quest isn't very complicated, but it requires paying a lot of attention. Unlike earlier, you're not supposed to explore the surroundings or look for any switches, but rather to put up good, old-fashioned fight. From the very beginning you have to be prepared to match up against a huge number of cannibals and marauders aided by a few husks and brutes. Your enemies will be attacking in waves so you will be able to find a moment to catch your breath and reload the weapon. Still, you will have to be prepared for a bit of a bloodshed.

After the shuttle lands, run up to the first cover and get prepared for the mass attack stop them donate your enemies want up to another and from Pro one: to another. At the same time, look around the surroundings because throughout the whole of the ship (being one big and enclosed arena) has been peppered with equipment (see: treasures). Leviathan's artifacts are of no significance whatsoever; that's why you should waste no ammo on destroying them.

Once you handle a sufficient number of enemies, the shuttle will go airborne and crash at the other end of the platform. This is equivalent to another the monster invasion, which will protect both you and their rescue vehicle. Although Lieut. Cortez will be asking for immediate help you do not need to hurry; he's invincible so he is not in danger. When you kill off all the enemies, you will be given [450 exp] and you'll be able to talk to your pilot.

.

After a short conversation you'll be given a new mission-recharging the generators that will open the gates to the battle mech. The missions seems difficult but it should pose no problem. Take a power-cell from the Lieutenant, and go to the nearest socket, which you can find to the left . When the cell runs flat, go back for the next one. You should repeat the operation until the blast door is open. Don't worry about enemies while doing that - eliminate only those that pose the most immediate threat.. The remaining ones may be well ignored. If you find the fight problematic, you may equip Hydra rocket launcher that you will find near Cortez - it is very effective against brutes.

As soon as the blast door opens, run inside, and get into the Tryton Suit (that's what the mech has been named). Their equipment is very powerful and that's why you will have no problems eliminating the remaining enemies. Once all of them fall, approach Lieutenant Cortez and watch the cut scene. This is the last occasion to search for useful equipment and its location-when you go underwater, there will be no coming back!

Go straight ahead in the direction in which Shepard launches flares. There's only one path, so you cannot possibly go astray. When you reach a large gap, you need to jump down into it. Go straight ahead and meet the Leviathan.

Regardless of the used dialogue options, Leviathan will join the allied team. That's where the adventure draws to an end. Congratulations!
