Cheat mode:

　　Note: This procedure involves editing a game file; create a backup copy of the file before proceeding. Use a text editor to edit the "diff_easy.cfg", "diff_normal.cfg", or "diff_hard.cfg" file in the "crysisgameconfig" directory to change game play under the Easy, Normal, or Hard difficulty settings. Insert the following lines to get God mode and unlimited ammunition. This may also be done in the demo version of the game.

　　God Mode - g_godMode = 1

　　No Target - ai_IgnorePlayer = 1

　　No Weapon Limit - i_noweaponlimit = 1

　　Unlimited Ammo - i_unlimitedammo = 1

　　You can also modify your suit stats. For example:

　　-- Player Health/Energy/Suit

　　// No energy loss

　　g_suitCloakEnergyDrainAdjuster = 0

　　// No energy cost

　　g_suitRecoilEnergyCost = 0

　　// Run faster

　　g_suitSpeedMult = 2.85

　　// More armor points

　　g_suitArmorHealthValue = 900.0

　　// Instant health regen

　　g_playerSuitArmorModeHealthRegenTime = 0

　　// Instant health regen while moving

　　g_playerSuitArmorModeHealthRegenTimeMoving = 0

　　// Set health regen time to 0

　　g_playerSuitHealthRegenTime = 0

　　// Set regen time while walking to 0

　　g_playerSuitHealthRegenTimeMoving = 0

　　// No waiting until regen starts

　　g_playerSuitHealthRegenDelay = 0

　　// Instant energy

　　g_playerSuitEnergyRechargeTimeArmor = 0

　　//Instant energy while moving

　　g_playerSuitEnergyRechargeTimeArmorMoving = 0

　　// Set energy regen time to 0

　　g_playerSuitEnergyRechargeTime = 0

　　// Do not wait until energy regen starts

　　g_playerSuitEnergyRechargeDelay = 0

　　// Extra health

　　g_playerHealthValue = 900.0

　　// Set difficulty, 1 is easy, 4 is most difficult

　　g_difficultyLevel = 1

　　After making all of your edits, save the file, load up a new game and see what you've edited!
