The original Left 4 Dead had a story too. I borrowed my friend's copy of this game (I have the original and he doesn't, he has the sequel and I don't, we basically traded) and it really is fun. I usually play on Easy mode, which allows me to screw around better and blow up Witches and Tanks with the grenade launcher and slice hordes through with the chainsaw. Good good fun. I haven't gotten the Passing, though. So sad about that.
