To edit the Crysis configuration files:

• Locate the game configuration files in the Config folder. The folder will likely be under C:\Program Files\Electronic Arts\Crytek\Crysis\Game\Config.
• If you can’t find the correct folder, use a file search tool.
• Identify the .cfg file that corresponds to the difficulty level you’re playing. There are four choices:

diff_easy.cfg
diff_normal.cfg
diff_hard.cfg
diff_bauer.cfg

• Back up the .cfg file you plan to edit. To save a backup in the same folder as the config file, make a copy of the file and give the copy a different name, such as BACKUP_diff_easy.cfg.
• Open the original .cfg file in a text editor, for example, Notepad.
• Add one or more of the cheat codes below to the end of the file. For example, to activate god mode, add the following line to the file:

g_godMode = 1

• Enter each cheat code on a new line.
• Save the .cfg file.

Start the game on the desired difficulty level to begin playing with cheats enabled.
