That should be a cheat or something, it kills everything in one hit lol.
Especially after you beat the game, and you unlock the infinite rocket launcher...pwned.
tip... okay...
when fighting the garrador(claws guy) you do not need to shoot him, or run away from him. Simply back up from him slowly, and wait till he passes you, then slowly turn around, pop him in the back, and then walk somewhere else.
Great, I'm moving. Who knows when you'll see me again.
