God Mode
 Locate the difficulty files in your Crysis installation folder
(ie:Доступно только для пользователей). These files are called diff_easy.cfg,
diff_normal.cfg, diff_hard.cfg and diff_bauer.cfg. Open the file (with
Notepad) that corresponds to the difficulty level you are playing. Add
the following line to the end of the file and save it:

g_godMode = 1 

 Now, when playing your health will still decrease but you will
not die. Instead, your health and armor will automatically replenish
when your health reaches 0.

Additional Cheats
 Using the same method as above, add the following lines to the
end of your config file for the corresponding effect:

Cheat code: Effect:

i_unlimitedammo = 1 Unlimited Ammo

ai_IgnorePlayer = 1 Enemies Ignore You

i_noweaponlimit = 1 Carry Unlimited Number of Weapons
