Slice, dice, smash, shoot, and impale zombies, LOTS of zombies.
Despite that, there's nothing more satisfying that cracking an undead mans skull open with a bowling ball. OH! Or a sitting bench.....Oh, or a hockey stick! The list doesn't end there, turn pretty much any trinket into an embodiment of zombie doom. The zombies however are, once again, the least of your problems. During the game you'll encounter psychopaths, and they prove far more formidable that any zombie. You'll end up playing through the beginning of the game several times just to level up enough and learn where the weapons are to be able to beat them.
All in all, you could really enjoy this game just standing anywhere in the mall and killing stuff. An overall inventive zombie game that's just fun anyway you look at it.
