Get L4D on halloween and you'll be able to play it on november 1st when the multiplayer demo is available to ppl who preordered it, Its gonna be pretty long for a demo as well and the replayability on it is pretty good.
Oh yea theres also garrysmod which is only $10 and you can play co-op in it as well along with zombie survival, roleplay (up to 64 player) and stranded which is where you have to co-operate together to survive the wilderness (gathering resources to survive).
