press ~ and enter "god" for god mode, and "impulse 9" twice for all weapons and ammo. there's more cheats but these are really important. u hav to enter god mode at a new level.
to play in nightmare mode, u hav to go the episode 4, try to fall through the water and land on the beams, jump through the doorway and its there. Nightmare mode is so hard, it was hidden so people wouldn't go through it on accident.
this series is awesome! the music is amazing. sounds like spanish music with the guitar but awesome! Keep goin with the series! note: for SA 4, u hav to play it on addictinggames bc the gigolo level wont work anywhere else 10/5
for god mode and all weapons with ammo, press ~ and type "go" and press enter "impulse 9" for weapons. can enter again for ammo refill. keep this one alive!
that cat had it comin! if u play sift heads world 4, after beating the game, in the basement safehouse, u can find mobo there, along with the cat now stuffed! lol. also, i cant beat the cop level. i must suck :(
@chaotickiller, on krazyletter.com, search for madness and u can find the TAR mod, and armory mod, also there are other good ones there too. i would definity check it out there
