Hilarious, but very short
If you don't play the first level (after the little section at the beginning where you learn to bite peoples heads off) and say AWESOME!! HAHAHA!!! then you probably won't like the rest of the game.
in a nutshell: you are a zombie with a background in this town. you have some people to get even with for your death, and a girl to get back to. so you run around town biting, beating or possessing people using your arsenal of gut weapons. yes, all your weapons are made up of your body parts. this sucks when you are at a distance and they are shooting at you with unnatuarally good accuracy.
this would be a major con. the fact that it is unreasonably hard to hide from the enemy, especially when you're facing the military, and you have no ranged weaponary. i have found, crouching behind sandbags can immediately cause them to forget where you are.
good: you get to bite people's heads off, watch blood fly everywhere, and create a semi-large horde of zombie companions. plus, its about as close as you'll get to dead rising without a 360
bad: very short, but i was starting to get tired with it anyway. stupidly hard parts when you encounter groups of military with powerful guns and excellent accuracy.
