Cheat Code
Before You begin please bare in mind You'll be changing files to make this work so make a backup copy before You begin. Open the file user.cfg from the installation folder with a normal text editor. Make a backup first! To activate the cheats you have to replace the word OFF and change it with ON:
g_global_god off
g_unlimitedammo off
to:
g_global_god on
g_unlimitedammo on
After editing these two lines, save the file and restart the game. The cheats God mode and unlimited ammo are now active.
