I was wondering if there was a "limited" God mode for GTAIV. Sort of like the Buddha cheat from Source games, where you take damage until 1HP, so you're not invincible but you still can't die. I love getting into huge shootouts with the cops, but anything above heat level 4 is pretty tough to survive and successfully get away from.
Even better would be a impervious to gunfire mod. Where you can die from almost anything (explosions, falling etc) except gunfire. Does anything like this exist?
My apologies if this is common knowledge. I just recently finished GTA IV and was intruiged by some Youtube vids.
