For all your zombie killing needs Dead Rising 2: Case Zero has got you covered.

User Rating: 8.5 | Dead Rising 2: Case Zero X360
The game is short but worth the price, but then again who can put a price on being able to jump kick a zombie's head off. Its also an easy and fun game with a lot of replay value despite being short. however you have to remember that its kind off like a demo for dead rising 2 so if you are a fan of the first game you definitely have to play it. There aren't really that many changes but everything is really improved the game looks better,boss fights aren't as frustrating, combining weapons is very satisfying and now you can actually aim a gun and move at the same time. If this is a sign of things to come in dead rising 2 then that game will be as fun as zombie killing can possibly get. If you are anything like me and dream of the world one day becoming a zombie infested wasteland then im telling you this is as close as it gets. There is nothing more comforting and satisfying ,in a sick way, then seeing a group of zombies with servant-bot's face wondering about then taking a boomstick and tearing them apart limb by limb, literally.
