Call Of Duty

To enable Call of Duty cheats in the demo, modify your CoD Single Player shortcut and add the following text in the target field AFTER all the other stuff:
"+set monkeytoy 0 +set sv_cheats 1" (without the quotes)
Then start the game using that shortcut and press [~] to open the console, in there type:
god - God mode
give - Gives indicated item
give health - Full health
notarget - The enemies won't shoot you
noclip - You can go straigh through walls
give all - Gives all items (DO NOT TRY THIS, crashes the game)
give ammo - Gives ammunition (DO NOT TRY THIS, crashes the game)
NOTE: If after you type one of these codes in the console it tells you that "sv_cheats are read only", then try typing this into the console: "setrandom sv_cheats 1" (without the quotes). If you, on the other hand, are getting "cheats are not enabled on this server" message then type: "spdevmap burnville" (without the quotes).
