Screw the shopping mall — if we're going to survive a zombie outbreak, why not do it in Vegas? Dead Rising 2 ($60) brings all the brains-eating action and dark hilarity of the original to a new setting — fictional Fortune City — while adding new characters, two-player coop and online multiplayer modes, and combo weapons, which let you duct tape two different items together, allowing for tools like the chainsaw-on-a-stick.
