Launch Day Guide
Over the last few months, we’ve spent a lot of time previewing Deus Ex: Human Revolution and learned a few things that might benefit you to know right out of the gate. These are some generalized tips that’ll help you excel as you get your feet under you in 2027 and avoid being just another cyborg getting sold for scrap behind the local LIMB clinic.
Keep in mind that these aren’t hard-and-fast rules, just some tips from the things we’ve seen so far. How you play DXHR is very much a part of the experience, so if you’re feeling lucky and confident, disregard these rules and make up your own. Just… bring ammo.
1. Decide on a Specialization
In the opening missions of DXHR, you’re going to get some information about yourself, and this is key to how you’re going to play the game going forward. Do you intend to shoot everyone who stands in your way in the face, grinning in their eyes as they bleed to death at your feet? Or are you more thoughtful, exploring the world and looking for alternative paths to avoid conflict? Would you prefer to hack the planet? These are things you’ll need to know, and how you handle the opening missions will help you make some decisions.
First up, you should pick a specialization and make your augmentation choices specifically to aid that choice early on. Experience and money can be traded for “Praxis points,” which you can use to upgrade your augments, but there are a whole lot of possible upgrades — so many that it can be overwhelming. Getting a little of everything works, but it’s not very effective. You’re better off trying to concentrate a little bit early on so you don’t wind up wishing you had more hacking ability or arm strength because you opted for thicker armor.
Here are some suggested early augs:
Explorer: See through walls, arm strength, hacking, punch through walls
Stealthy: Cloaking, hacking, see through walls
Gun slinger: Dermal armor, aim steadying, punch through walls, inventory upgrade
2. Get Hacking Upgrades Early
DXHR is a huge world, and while you can play through the game with just the information you get from the main quest and side quests, you’ll expand the world and the primary and secondary plot lines substantially if you hack. A lot. In fact, any time you go up against a computer system, a locked door, a secret safe or a laser defense grid, you’ll need hacking abilities. It’s an invaluable skill just for getting around, and it’s especially handy if you want to complete all the game’s sidequests. Early on you’ll want to boost hacking up to at least level 2 or 3 just to get around and complete everything.
However, keep in mind: if you hit a door you can’t get through, check it’s durability, which appears when you highlight it to try to open it. Most doors can be blown open with explosives, even if you’re not the world’s greatest hacker. You’re not so lucky with computers, though.
3. Explore Everything — If You’re Into That
The more you explore, read and hack, the better your overall experience with DXHR is to be, provided you’re interested in the game’s story. If you’re into the world Eidos Montreal has built, by all means, go nuts. Look for all the easter eggs, hidden ammo caches, e-books and secret emails you can find. Most everything you do rewards you with experience points — hacking emails, finding your way through air vents, even punching people with your stealth takedown maneuver. You’re rewarded for all the things you do, so if you like exploring, it’ll benefit you in lots of ways and make you stronger, both through what you discover and through your augments and experience points.
4. Choose Your Weapons
Chances are really good that early in the game, your inventory is going to be pretty limited for a long time. You can upgrade it through augments, but the more you spend on your inventory, the less you can spend on stealth or hacking or defense. The trouble is, there are lots of guns in DXHR, and it’s tempting to pick up everything and hang onto it, but this pack-rat mentality is actually a big negative. There’s very little ammo dropped in DXHR, despite the glut of enemies — most bad guys will drop only a few bullets for their respective weapons, and you’ll never have more than a few clips for any given gun. This becomes much worse if you’re dedicating space to carrying lots of different guns and only a little ammo for each one.
Instead, consider how you want to play the game and pick two (max three) go-to weapons you’ll want to have with you most of the time. I kept my tranquilizer rifle from the game’s first mission for my entire 31-hour play time; I also had a non-lethal stun-gun I picked up about two hours in during my first visit to Detroit, and a combat rifle I kept around for emergencies when lethal force was necessary. While I occasionally had to use other hardware, for the most part these were my weapons throughout the game, and by the end I had decked them out with mods to the point where I wouldn’t ever want to use another gun. The point is, you’re better off creating a few great guns than carrying lots of crappy ones.
5. Always Buy Ammo
There’s not a lot of ammo around in DXHR, as I mentioned, and I made the mistake early on of getting myself into some very bad situations in which I had nothing to fire out of my guns. Having empty guns that require you to constantly scavenge for hardware before you can even put up a fight is a great way to get yourself killed against DXHR’s tough enemies. Protagonist Adam Jensen isn’t invincible — he’s actually pretty frail. Your weapons are your best defense, so make sure you keep them fully stocked. And on that note…
6. Spend Your Money
If you do any kind of exploring and side quests, you’re going to likely be flooded with money for much of the game. It might seem like you don’t have much at the very start of the game, but before long, you’ll always have a healthy supply of credits. Money can be spent to buy you new weapons, ammunition, mods and even Praxis points at LIMB clinics. Spend it. Buy up the Praxis at the LIMB clinics and it’s gone, but spending the cash is generally worth it for the advantages you get for being augmented more than you were.
If you can’t buy Praxis, go try to buy weapon mods. Always make your guns better than they are if you can. After that, keep stocked in ammo and food items to keep your energy cells charged. It’s never fun to try to silently take down an enemy only to find you don’t have the juice to do so.
7. Keep Your Head Down
Even if you’re a run-and-gun type, there’s a cover system in DXHR for a reason. That reason is that you will die often if you ignore the cover system. Jensen goes down in just a few shots, so it’s never wise to invite enemy fire. What’s more, you’ll need to use the cover system if you intend to use stealth as your primary means of playing the game, so get used to stay down and out of sight.
Even if you don’t intend to hide from your enemies, however, you should at least pick how you encounter them. Use cover to stay hidden and then launch ambushes and give enemies the slip, and stay down whenever you’re in a fire fight to avoid getting killed. Just be careful: Enemies will throw grenades at your position when they know where you are, and occasionally they’ll send teams to flank your or rush your position.
8. Remember: There’s ALWAYS Another Solution
One thing that’s important to note about DXHR is that there’s never a situation that can only be solved one way. If you ever run up against something that seems insurmountable, or a situation that seems like you’re stuck, look around. Explore the rest of the area. Check in corners and especially behind objects like crates or vending machines. Hidden ventilation shafts, security terminals, pocket secretaries and lots of other objects and paths are scattered around everywhere that will allow you to approach a situation in a different way. Turn bad situations to your advantage whenever you can. Every problem in DXHR has multiple solutions, and you’ll eventually find them if you look hard enough. So keep looking.

Introduction Mission
After the opening cinematics, approach Meagan and talk to her. You will now go through a lengthy sequence that takes you through the labs and up to David Sarif’s office. When the alarms start going off, you will resume control over the character.
Approach the elevator with the blinking red light and activate the control panel. Enter the code: 0451 to open the door, then step inside and press the button to go down.
When the doors open, you can use the tutorial to learn the navigation controls or just start moving left down the hallway. Follow the corridor around and continue through the half-closed entranceway by ducking under it.
Continue following the hallway around to the left, moving down a series of staircases as you go, and approach the glass wall. Take a moment to watch the scientists get brutally eliminated, then enter the room to your left. Watch the tutorial on moving objects if need be.
Remove the crates that block the vent on the wall in front of you, then open the grate and climb into the air duct. Follow the ventilation shaft to the next grate and remove it to enter the next area.
Move through the doorway that’s been blown open and enter the hallway on the left, then watch the tutorial on combat if necessary. Continue through the corridor and approach the door marked SL-001 to open it.
As soon as you enter the next room crouch down behind the nearby crates. Wait for the scientist to be killed on the upper level, then aim towards the bottom of the stairs across the room. When the enemies appear, wait for them to reach the ground floor before popping up to eliminate them.
If you take any damage during the game, the screen will turn a crimson red. When this happens, take cover and wait until it resumes it’s normal color to restore your state of health.
Pick up ammo from the fallen enemies and head up the staircase, then open the door at the top and make a right down the hall. Follow the corridor around and jump over the crates blocking your path, then continue through the hallway and approach the next door on your left.
Take cover beside the entrance before activating the door. Once you open it, lean out from cover to eliminate the enemies directly in front of you and the ones at the far end of the room. If you are unable to eliminate the further threats right away, they will move to the left side of the area.
Enter the doorway at the opposite end of the room and go down the hallway to your right. Duck under the half-closed entrance and watch the scientist get gunned down to see the disappearing enemy in action.
Once the doors open take cover behind the railing in front of you and use it to safely eliminate the enemies that appear below. When all threats have been removed, move downstairs and enter the burning hallway the enemies appeared from to complete the mission.
Back in the Saddle
After getting your assignment, move forward up the escalator on the opposite side of the room and make a left at the top. You can use this opportunity to talk with random employees and interact with various objects, but none of that is essential to your current task.
Enter the door within the red glass marked Tech. Lab. Frank Pritchard’s name is on the sign beside it. Talk with Frank to have your retinal display repaired and choose to either ignore or confront him. Confronting him will reveal extraneous background information.
Return to the door with the two armed guards and enter into the next area, then move left and pass through the two sets of double glass doors to reach the helipad. Talk with Faridah Malik who’s leaning against the helicopter to activate the cut scene.
You can now choose to either reassure or challenge her. Challenging her will reveal more backstory. Let her know you’re ready to activate the next mission.
