Red Dead Redemption transports players to Rockstar’s vision of the American West at the turn of the 20^thcentury. It follows the tale of reformed outlaw John Marston as he strives to protect his family and bring the members of his former gang to justice. Alongside the rich, immersive single-player experience,  Red Dead Redemption’s multiplayer offers a world of dynamic challenges and competitive games suited for a player of any skill level.

Undead Nightmare  expands the single-player narrative as John Marston attempts to eradicate a mysterious zombie outbreak and discover a cure. The single-player experience features new challenges, quests, and ambient events, including Missing Persons, where the player must find a missing survivor lost amongst the throngs of undead. New multiplayer content includes Undead Overrun, a multiplayer survival mode where waves of infected attack and players must work together to stay alive against increasingly difficult odds.
