Deus Ex Human Revolution can be quite challenging to master but I located this accessible reference Deus Ex Human Revolution Cheats guide that helped me throughout my climb to the top levels of the game.
Deus Ex Human Revolution Cheats are entered 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 shows "Click to continue" or "Main menu". Deus Ex Human Revolution Cheats can then be entered for the desired effect.
You will have to enter the codes in blindly because there is no dialog box on display. If you enter one cheats with mistakes, you are messing up your opportunities typing any future cheat codes. If you are certain you made an error entering the Deus Ex Human Revolution Cheats, you'll have to restart the game for the cheats to work again.
In the guide you will acquire cheat codes for all of the Need For Speed games, on all platforms. All games from Need For Speed Underground to Need For Speed Most Wanted, Carbon,etc. on PC, Xbox, PS3, Xbox 360, Sony PSP, DS, Wii and etc..
