Red Dead Redemption: Undead Nightmare

Red Dead Redemption: Undead Nightmare, later released as a standalone game, adds a new single-player experience in which Marston searches for a cure for an infectious zombie plague that has swept across the Old West.

Across the vast Western frontier, a plague is spreading... When former outlaw John Marston wakes up at his farmhouse, he finds a world gone insane: overnight, deranged hordes have overrun the towns and outposts of the American frontier. In a desperate attempt to save his family, Marston must traverse a world torn apart by chaos and disorder, using every skill he has to survive long enough to find a cure. The Red Dead Redemption: Undead Nightmare collection is now available on disc worldwide. Take on the Dying and Undead West in multiplayer with exciting Co-Op missions and Competitive Modes. Attack and defend in Stronghold mode, or take over territory in Land Grab. Play online as iconic characters from Red Dead Revolver or as the legends from Red Dead Redemption. School your friends in Poker, Liar’s Dice and Horse Racing and annihilate your enemies with the deadly Tomahawk and Explosive Rifle.
