I've copied and pasted the correct path into a shortcut to HL, and gotten the god mode code to work fine, however /impulse 101 ,(all weapons, ammo.) will NOT work, I've tried everything, doing a quick save then load, typed in sv_cheats 1, nothing works.
help?

sv_cheats 1 must be run from the shortcut, or typed in during game, THEN a new game made.

But if GOD mode works, so should anything else. "Nothing works". What? :s

Just save a lot and dont use cheats.
