Left 4 Dead 2 is one of the only games Valve hasn't messed up at all, and it's a great game for that. L4D2 is a lot more fun and more in depth than most zombie games, and will keep you busy longer than any other zombie game, Billy Mays guarantee it. It's community is still going, and there's a ton of comunity made maps that are actually quite good, so you should really give this game a try. If you like it, you'll spend dozens. if not hundreds of hours on it.
