What's better than playing a game where you have to fight your way through a zombie outbreak to freedom? Playing it with three of your friends. Left 4 Dead ($54; November 17) will offer a 4-player online co-op, online multiplayer, split-screen offline, and 8-player versus online modes to go along with the zombie-blasting fun. Great visuals, fast, frantic action, and lots and lots of undead. What's not to like?
