Brains=Sex for zombies. And this game has lots of brains....
Stubbs travels all around Punchbowl. The levels are all refrences to classic zombie films (such as a mall and a farm). The civilians all run around screaming like crazy. Stubbs dosen't like screaming. So he eats their brains, and brings them to the ranks of the undead. Sure, the zombie AI sucks, but you have around 20 of them at a time, which can overwhelm the somewhat-better-than-average AI of the cops, scientist and other common enemies (which also make good zombies)
Stubbs himself looks great. The people, however, all look the same. Even if that was the case in the 1960's, the should at least change clothes.... and faces. And there is a technical glitch that leaves a bit of space between Stubbs' mouth and the head of his lunch.
The soundtrack is great, it's old 60's songs with a modern day twist put on them. I even bough the soundtrack online. The sound effects are awesome as well, the voice acting is great and hilarious.
A lot of games just suck at being funny, but this one definitley is. I mean, it's made by X Bungie employees, and you can see all the funny easter eggs hidden in Halo. They even have a character named "Chief Masters" as a refrence to Halo.
Overall, the game is short. Really short. But there is co-op and other fun little things you can do with Stubbs that will keep you coming back for a while. It's a definite must buy, you NEED to get this now. You'll laugh your pants off.
