Deus Ex Human Revolution can be quite troublesome to master but I located this handy reference Deus Ex Human Revolution Cheats guide that helped me throughout my ascend to the top of the game.
Deus Ex Human Revolution Cheats are typed at the main menu. A confirmation message will display when a cheat code is typed with no mistakes.
In Cheat Mode, Start up your game and continue to the screen that displays "Click to continue" or "Main menu". Deus Ex Human Revolution Cheats can then be typed for the chosen outcome.
You'll have to input the codes in blindly because there is no dialog box on screen. If you type a single cheats code with errors, you are messing up your chances entering any future cheat codes. If you're sure you made a mistake entering the Deus Ex Human Revolution Cheats, you'll have to restart the game for the codes to work one more time.
In the guide you will acquire codes for the complete Need For Speed video games, on all platforms. All games from Need For Speed Underground to Need For Speed Most Wanted, Carbon,etc. on Xbox, PS3, Xbox 360, Sony PSP, DS, Wii, PC and etc..
