Don't forget the unlimited Clip Ammo, and bullets hitting the ground when the person is aiming pretty high. Movies like Star Wars are good since the people with guns don't reall miss, but the victims block it.
And this has what to do with the topic? Oh, that's right. Not a damn thing. Nice spam.
I think this would be a pretty good idea. People usually like seeing shit get shot to hell and blown up, much like in the Resident Evil movie. I say if RE can make it in the movies, HL will have no trouble.
