Deus Ex: Human Revolution augmentations guide

Augmentations are a huge part of Deus Ex: Human Revolution, and picking the right ones can make a huge difference with how you play the game. The thing is, until you’ve spent your Praxis points, it’s not always clear how each upgrade functions. We take a look at all of your options and explain how each of the upgrades works and what kind of playstyle it’s best suited for.

Cranium Augmentations

Social Enhancer

This is an interesting aug that modifies how you can handle the game’s conversation and dialogue situations. During dialogue with a major character, three boxes will appear, one gives you some insight into the character’s background and personality, one is a meter indicating what your current level of influence with that character is, and the one in the upper left helps you determine what emotional type the person is. (Conversations with minor characters only get the last box displayed.)

While the character talks, each personality type box will flicker, indicating what kind of person you’re dealing with. At certain points during the conversation, you will be allowed to “chemically persuade” them by releasing pheromones and asking a question based on their personality type. Note that in some cases this chemical persuasion tactic will allow you to get information or rewards from characters that would otherwise not be possible.

Worth Buying? 

Yes. It can be a huge help when trying to outwit the major plot characters, but the fact it can be used to get special outcomes definitely makes it worth it.

Radar 1 

Tracks hostile targets/cameras on your radar, though you actually have to see them before they’ll pop up on your map.

Worth Buying? 

N/A You get this one for free when you start the game, so enjoy.

Radar 2 

Doubles your radar’s range and eliminates the need for you to see them before they’ll appear on the map.

Worth Buying? 

Yes. There’s a lot of upgrades available for your map, but this is probably the only one you need. The extended range is good, but the fact it automatically detects enemies in the area makes it great. This should be one of your very first augments. It's also an easy way to unlock the Transhumanism Achievement Trophy.


You begin the game with this maxed out, so there’s not much to say about this other than that it’s what allows you to talk to people on your coms without being heard by nearby enemies.

Worth Buying? 


Stealth Enhancer

Noise Feedback

Displays a small circle around your character on the map, visibly displaying how much noise you’re making while moving and whether guards in the area will be able to hear it.

Worth Buying? 

Not at all. If you’re trying to be stealth you should probably be crouch walking, which is totally silent. Running between point A to point B will almost certainly get you seen even if you aren't heard.

Cones of Vision

Enemies, robots and cameras on your map are displayed with an MGS styled vision cone that reveals where they’re looking

Worth Buying? 

No. While it can be a little difficult to tell which way some of the arrows are facing, you can usually easily tell where enemies are looking with a little scouting from behind cover.

    i have been stuck on the 3rd boss now for hours if not days and cant seem to get close to killing there a way of killing him that i cant seem to see or what if someone can help me it would be great thanks

    I found the Implanted Rebreather extremely useful. Yes, enemies who use gas grenades are few and far between, but there are more areas than you think that make use of gas, and enemies can't follow you through it. Furthermore, it makes it much safer to use your own gas grenades and gas mines, which often have a deceptively long range. For taking down multiple enemies non-lethally and without getting caught, a gas mine cannot be beat, but without Implanted Rebreather, you can't use it if they're close. With it, you don't even have to care. Implanted Rebreather gets high marks from me because it not only opens up more paths to you, it makes your own Gas weapons more usable.

    Good guide but, I disagree about the arm stabilizer. The arm stabilizer doesn't just negate your reticule from spreading when firing while moving it eliminates it from spreading period even while motionless..which means NO bullets spread= supreme accuracy
  • Amunnakht - September 16, 2011 11:15 p.m.

    Forgot to mention, if you go with the laser upgrade, then arm stabilizer is NOT as important and the no recoil aug is more useful

    Thanks for the input on the Icarus System, those are good points. Went ahead and revised the entry on that.
  • bamb0o-stick - August 28, 2011 9:23 a.m.

    I'm agreeing with Tyrlanae that the Icarus system isn't as bad as you say. It should be pointed out the Icarus system has an option to land with a "stun" attack. If you click the LEFT MOUSE button on the PC version you will unleash a shockwave when you land making it useful on group ambushes. Also, there was a situation where I was being chased by gunmen and I improvised an escape by jumping straight DOWN a winding staircase (must've been five flights) and the Icarus system totally saved my ass back there. Probably one of my favorite moments in the game for me.

    Wish this was up when I went through Detroit and couldn't finish the side quests because I picked the wrong augmentations.
  • evandang - August 27, 2011 3:07 p.m.

    There are a lot of apprently hilariously worthless upgrades here
  • Tyrlanae - August 27, 2011 9:43 a.m.

    Bugger all, forgot to mention that the aim assist has a secondary function not listed here - It stabilizes any and all rifle sway if you're a fan of scoped weapons, so this is extremely useful for sniper type players who want more precise aiming.
  • Tyrlanae - August 27, 2011 9:39 a.m.

    Going to have to jump on the train here and agree that the Icarus Landing System is by far one of my favorite augmentations. The reasons have already been listed but I'll reiterate a few; Like the value of a quick decent off a roof for time saving reasons, and the many hidden praxis kits that are easily obtainable with this augmentation, and let's not forget the value of the Icarus Bomb! I'm also undecided about the stealth augs, like the cone of vision etc., they're not necessary but they can be a nice thing to have.
  • Hobogonigal - August 27, 2011 9:31 a.m.

    I wasted a point on the stealth aug that lets you see how far your sound travels. I can't even tell what it does! I think I'll get the invisibility next but I might have to upgrade my energy capacity.
  • Kyo - August 27, 2011 8:41 a.m.

    Yea, I have to disagree about the Icarus Landing System it's very very useful. It ranges from keeping yourself from dying from randomly falling like an idiot, as you said.. but it also helps get to hard to reach places 5x faster than walking around and finding the correct path. Similarly, it helps you take very fast shortcuts, so instead of re-walking the same worn down path you've been taking over and over again, just jump right down from the roof/bridge/whatever to the street and you're good to go. Not to mention jumping down and getting behind cover instead of crawling through a sewer, or facing enenmies head on helps a lot too.
  • Doctalen - August 27, 2011 8:31 a.m.

    I actually like the Icarus, not only do I find it entertaining but with its upgraded shock aug. it actually becomes fairly useful. I try to play a stealth play through and even it still comes in handy like when you are trying to access the apartment building in Shanghi (forgetting the name now). Instead of trying to sneak past the guards all you have to do is climb on to the roof top, Icarus smash the two guards in the entrance and walk to the elevator.
  • sweetchiliheat - August 27, 2011 7:31 a.m.

    IMO, Icarus is an extremely useful augement, as many shortcuts in the game containing praxis points use this augment. This would be one of my highly rated augments.
  • Shanetexas - August 27, 2011 7:31 a.m.

    Quick question: If you buy this game online on Steam, does that mean you'll have to sign up with that EA b.s. program in order to play the game? Or is that when you buy it retail? Plus I have to type [ISaully Tripathi,] in the reCaptcha. Wah.
  • Roland_D11 - August 27, 2011 4:28 p.m.

    The game is published by Square Enix and developed by Eidos, EA has nothing to do with it. Steam is mandatory, nothing else :-)
  • taokaka - August 27, 2011 3:48 a.m.

    not a wrong choice yet, I was so tempted to get icarus landing because it looked so badass in the trailer but now I won't.
  • KielbasaNinja - August 27, 2011 1:10 a.m.

    Quite helpful. Nice to see someone else using their praxis similarly to myself. I was sitting on four points for a bit just because I was afraid of wasting them on something useless. It's not like you can get them back. Did you have all the augments by the end of the game?
  • GamesRadarMichaelGrimm - August 27, 2011 1:46 a.m.

    I did a pretty complete run on my second playthrough (all side missions, backtracking for extra cash/XP) and still only ended up with like ~85% of the augs by the very end.
