Start the game by running the game from your RUN menu with:
Now you can bring down the console command box at any time
during the game with the ~ key (tilde).
Now before loading a map or game, you must open your console and type "sv_cheats 1" (excluding ""). Alternatively you may place the command in your "C:\GameFolder\config.cfg" file with notepad, so it will be automatically set next time you
open the game.
You may now use the following commands (excluding ""):
"god" - God Mode
"noclip" - NOCLIP Mode : Fly through walls
"notarget" - No Target Mode
"impulse 101" - Gives all weapons
"sv_gravity x" - Adjusts Gravity where when X = 800 the game uses default gravity and when X = 0 there is no gravity.
"sv_accelerate x" - Adjusts air acceleration so you move more when you jump. Default = 10 but increase for more effective bunnyhopping :)
"skill x" - Adjusts skill in-game, 1 = Easiest, 3 = Hardest.
