Games cheat codes: Deus Ex Human Revolution

Infinite XP

This glitch works anywhere, but the first and easiest place to do it is at Adam Jensen's computer, which is located in his office at Sarif HQ, after returning from the Sarif Manufacturing Plant hostage situation. Use the discovered Praxis Kit and an earned Praxis point to upgrade to Hacking Security Level 3. Try to collect as many Nuke Programs as possible to help speed up the process. The Nuke Programs can be collected in the Sarif Manufacturing Plant, or while searching and hacking into the computers around Sarif HQ. Before starting a hack, save the game. Hack all optional nodes, or the Network node to instantly complete the hack. Do not exit out of the hack or press a button to complete it; you will also want to make sure you are getting an +XP bonus. While using Adam Jensen's computer, hacking the special reward nodes will get you a +500 XP bonus. When you have acquired the optional nodes or captured the network node, pause the game, and load the saved game created before you hacked. Again, do not complete the hack. When the "Access Granted" window appears, do not select "OK". Press Start, and you will notice you cannot save. Load the saved game you created before starting the hack. Then, try the hack again. Repeat the previous steps, and capture every optional node or the network node. The game will keep your previous +500 XP bonus. For your second try, you will get +1000 XP. For your third try, you will get +1500 XP, etc. Do the trick five times to get +2500 XP. Make sure to keep loading and never select "OK" to complete the hack. Repeat this trick as many times as desired to get a lot of XP early in the game. You can always return to Adam Jensen's computer later in the game to repeat this trick, or try it on other hacking challenges throughout the game. Note: This glitch was done on an unpatched version of the game. You can delete all patches for the game by using the "Clear hard drive cache" code for the Xbox 360.

Easy XP

When attempting a hack, save the game. Then, hack the optional nodes, but do not complete the hack. After you hack the nodes, load the previous saved game, and repeat the process. Once you finally complete the hack, you will get all the nodes (from the previous times you loaded) in addition to the nodes you get normally. Use this glitch on the computer in Jensen's office to get 500 XP every time you load for easy Praxis points. Note: This glitch was done on an unpatched version of the game. You can delete all patches for the game by using the "Clear hard drive cache" code for the Xbox 360.

Try to execute as many non-lethal takedowns/kills as possible to earn more XP than you get from lethal takedowns/kills. Additionally, if you have the Reflex Booster augmentation (which allows you to take down two enemies at once), you can get an easy 125 XP from a non-lethal takedown/kill compared to a lethal takedown/kill.

In Hengsha, every store has a back door. Open the door, and walk inside to get a 100 XP Traveler bonus.

Easy hacking

To keep attempting hacks without running out of hack attempts, when the system is alerted before you run out of time, press B to cancel hacking, then press Y, and the failed attempt will not count against your limited number of chances.

Easy kills

Upgrade Hacking and Strength to be able to pick up turrets, which have unlimited ammo. Set them down or let them fire while you move to easily clear out a room. You will still get XP and headshots. You can also do this with robots.

Easy stealth kills

To easily take down enemies silently, find an indestructible object such as a barrel or container, and carry it with you. When you find a group of enemies, stand in a position where you want an enemy to approach. While holding the object, throw it next to yourself or close to where you want the target to approach. The entire group of enemies will be alerted when they hear the object hit the ground or wall you threw it at, but only one should approach to investigate. The enemy will walk to the alerted area, stand where the sound came from, and then begin to walk back after finding nothing. You can then knock them out or kill them undetected. Note: If you throw the object a long distance, the investigating enemy may track the object's flight path directly back to your position. It is better to throw it nearby for repeated use.

Easy storage

To store an item instead of carrying it around, simply throw it on the ground. The game saves the location of items -- even when you leave the region.

Easy Funicular waiting

In Picus Communications, when you have to wait for the Funicular to come up, there will be enemies coming to kill you. Before you press the elevator button, block both entrances into the room with heavy objects. You can only do this if you have the Move/Lift Heavy Objects augment. There are two vending machines outside the room, two crates (one short, one big) next to the security computer, and the turret in the center that can be used to block the lower doorway and the side corridor. If you block the doorways correctly, the guards will stay in another room outside the entire time you are waiting for the Funicular. Note: It is recommended you save before pressing the elevator button in case the barricades do not work.
