It is a great game co-op is the thing whats it does different from other games is it creates a atmosphere like no other. okay so your playing with four friends on xbox live (assuming you have that many lol just kidding) you will be yelling at each other telling each other things like "HELP KILL THAT SMOKER HE HAS ME AHHH!!" or "YOU IDIOT STAY WITH THE GROUP!!!" thing like that tons of fun but my only complaint is there is only four movies to play so the awesome-ness is limited. So a buy yes definitely but remember this is a game to play with friends. versus mode is fun the respawn time is a little bit long 23 seconds or so but play as a zombie is a great feeling but again you most work together. So if you like shooters playing with your friends killing zombies being zombies then get Left 4 Dead.
