    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.

    Great guide! Definitely getting this game. My type of game. Serious mature real world storyline. Not the convoluted rolling your eyes Final Fantasy or MGS4 Japanese storyline. A thinking man’s RPG. The guide is going to be very helpful in starting the game so you get the most out of playing it. Thanks!

    Its too bad they don’t let you keep your weapons and ammo in game+.

    After several playthroughs I would have like to just fool around in the gaming environment. Use bazookas for the lonely guard, npcs etc. Just push the boundaries of the game and fool around. There’s no multiplayer to keep bringing me back and after 3-4 playthroughs I would have been nice to go guns blazing. I had fun replaying Resident evil 5 with infinite bazooka and ammo. Putting this would have been another incentive to keep replaying to get a infinite ammo bonus or something. Maybe they’ll change it or a DLC

    Just one thing. You let Malik die didn’t Ya…not nice, it’s actually possible to save’er, very hard though…if Ur playing on give me deus ex dificulty…xD.

    This was useful… But it depended on being able to hack things and when I try to look up the passcodes they don’t come up for the ‘TNNLHUB’ computer. As I have no hacking skill at all, this walkthrough became useless to me when it told me to hack something =’[

    It’s a great walkthrough, just not suited to everyone.

    Looking for a helpful comment about typhoon ammo and how to use for x360? I have the augmentation and ammo and i’ll get within 8m or so and its never available to use?? Any info is welcomed. thanks!


    On September 5, 2011 at 7:22 am

    Disregard post. sorry its dpad…duh :-)


    On September 7, 2011 at 8:26 pm

    I killed if I only absolutely had to, used tranq rifle and non-lethal take-downs most of the time, except for when malik was being attacked, and quests that required someone to die, like rotten business, and a few other times I used lethal force I probably forgot, I played the game realistically.

    Why are you comparing this to MGS or FF? MGS is a similar-game but is more story driven, and FF is on the other end of the spectrum. The storylines in all the Deus Ex games have been very weak, and are great for people who like popcorn movies like yourself, instead of something that contains a rich narrative. This isn’t a ‘thinking’ game due to its design of being able to beat the game without using a single augmentation. Any idiot can do it, like yourself.

    Actually go on the roof and look left jump ontop of the dryer vents and work you way to the buulding across from the roof you start on from there you can punch through a wall kill an enemy in the process and take out another down the hall you will find no were to go unless you have a landing upgrade which i dont so on the left is an old elivator shaft with a shotgun in it pick that up and jump down.


    On September 12, 2011 at 1:47 pm

    How the heck do you know when you can punch thru a wall? I’ve got the augmentation, and so far after 90hrs., I’ve had no luck……And for killing Bill, I’ve started over a dozen times trying to stock up, and that big sob still gets me.


    On September 13, 2011 at 10:46 am

    No mention of that mine though is there? You basterd.


    On September 16, 2011 at 12:26 pm

    Great guide =] anyways…just thought I’d let you know I found a way to walk through the front doors of the hive everytime without having to pay. If you examine the rooms of the Hung Hua hotel you should find a hive membership card. The bouncer will let you in like you’re a regular…not that it is absolutely necessary…just another option =]

    LOL MGS had a good storyline compared to this? If you say so…either way this game isnt really all that much of a prequel. It’s just a better made version of the first game. If you played this game without hacking then you probably missed out on about 50% of the content and upgrades. Stealing that MEPS gun from the police lockup was the best boost in the whole game for non-killers like myself. That gun was essential in keeping Malik alive by taking out both heavy gunners with one shot after sprinting up while invisible..then it was just take out the combat riflers with the stun gun, meps or just punch em. Between gas grenades and emp grenades i dont think i had a mech last longer than 5 sec after i cycled through my gear.

    Jenson’s voice, and sometimes his mannerisms, reminds me of Clint Eastwood.

    Has anyone registered this game with Square Enix?

    I haven’t. At least not yet. I read the legal stuff one had to sign up to first. Put me right off.

    hi, i just started the game and it would be a noob question but, where can we see achievements in game? there isn’t any achivements page that we can see them.

    i’m not sure im getting achievements so i jsut wanted to see them because it doesnt appear on bottom of my screen when i supposed to get them for example after first takedown or after first ghost. (i get ghost exp at left of screen but no achievement)

    someone please explain me how it works. thanks

    This is the best walkthrough I have found yet for this game. Of course, as you mentioned, there are many desk drawers and hidden areas to search, and sometimes valuable information and items can be found this way. It is very time consuming, however.

    One of the most amazing things in the game that I discovered, was that I could take control of turrets, and carry them around with me from floor to floor, and even carry one down on the funicular to protect me in the lower level of Picus Communications. It even attacked the robot at the bottom of the stairs and destroyed it for me. No other game I have ever played has allowed me to do something like this.

    I now have played through the game three times. The first time, I used a combination of lethal and non lethal weapons. I then played it and was able (with much difficulty), to go completely non lethal Except for the boss fights, of course. The last time, I tried to hunt down and kill every enemy in the game, using only lethal weapons. The most difficult fight in the game for me was trying to save Malik in non lethal mode.

    This game has captured my attention as much as the original Doom and Quake games I played many years ago, and I consider it to be in the top 5 of all the hundreds of games I have ever played since I started many years ago. It has prompted me to buy the original Deus Ex, and now I am playing it to compare the two.
