Zombies. Whether you love them, hate them, or are just plain sick of them, the ubiquitous undead have carved out a sizable niche in the world of video games. Unlike most monsters, zombies have very little in the way of defining characteristics, so they can be fast or slow, whole or mutilated, legion or solitary, hapless or superpowered--as long as they look like they were once people, you're pretty much set. Dead Nation serves up all of these vicious varieties and more, challenging you to blast your way through thousands of zombies while navigating a postapocalyptic city. Though your foes may be familiar, the detailed environments, upgradable weapons, and hidden bonuses make it rewarding to explore each area alone or with a friend in local or online cooperative play. Straightforward gameplay mechanics and thoughtful design touches combine to make Dead Nation a very fun game, proving there is still plenty of life in shooting the undead.
