This Xbox 360 community game goes to show that not all zombie games are good. Calling this game a Zombie one does Zombies a diservice anyway, as Zombies only feature as a power up.
The game is basically a Smash Brothers clone. You can choose one of about 10 characters, all who have a guitar they can attack with, as well as the usual punches and kicks. Upto 4 players can fight at once. The Zombies as said before only appear as a special move, so not worth getting at all! Boring!
