Stuck in a rut? don't know what to do? Just wanna have some fun? Then use some of these great single player cheats. We don't have multiplayer cheats, on the fact that multiplayer cheaters are godless bastards. More cheats comeing, as soon as they come in!
1. Create a copy of your single player desktop shortcut
2. Right-click on it and select "properties"
3. In the "Target" field, add the following to the very end (outside the quotes): +set sv_cheats 1
4. Click OK
5. Launch the game using that shortcut
6. Once you're in the game, you should be able to use the following cheat codes (hit the "~" key to bring down the console, then type them in):
/god (makes you invulnerable)
/notarget (makes enemies not attack you)
/noclip (lets you walk through walls)
/give all (gives you all weaps and ammo)

但是我照著做都沒辦法耶!!
有人成功嗎?
