In the lawless West, nowhere is safe. Between rebellious outlaws, crooked government and of course, the zombie hordes, it seems that a frontiersman just can't catch a break. That's right ~ unrelenting legions of the undead have invaded that already-wild landscape of the Western badlands, wreaking total havoc through towns and outposts normally only plagued by rogue gunfights and robberies. Once again, that rugged former outlaw, John Marston, finds himself caught in the action and fighting for survival ~ only this time, he's not just up against the bad guys, he'll have to take down the dead guys, too.Red Dead Redemption: Undead Nightmare propels you back to the American West with a terrifying new twist. Arm yourself with the powerful new Tomahawk and Explosive Rifle, venture into the graveyard and return to the role of John Marston as he faces dangerous, decaying enemies from four grotesque zombie classes and even undead and mythological animals. The corpse-conquering mayhem is monstrously intense in online multiplayer action that teams you up with or pits you against friends in Land Grab and Stronghold modes, as well as a variety of challenges, including Poker, Liar's Dice and Horse Racing. Play as your favorite iconic characters from Red Dead Revolver or as the legends from Red Dead Redemption. You may have tamed the Wild West before, but can you put the walking dead to rest?
