Dead Nation
This Playstation Network exclusive sees the player facing hordes and hordes of undead. Dead Nation is a twin stick shooter from the makers of Super Stardust HD, the Finnish studio Housemarque. The game features ten levels of frantic, top down view shooting, several zombie types, a ton of upgradeable weapons and both online and offline coop modes, where the second player simply takes over the second playable character, either on the couch or online. It takes a few nods from Left 4 Dead, whereas the undead horde can be attracted to car alarms, mines and the like, as well as timed standoffs against an unending onslaught of zombies while the players have to stand their ground.
