Red Dead Redemption: Undead Nightmare (Platinum Hits) (Xbox 360)

Red Dead Redemption: Undead Nightmare is a standalone expansion pack to the 2010 open world Western game Red Dead Redemption, it adds a non-canonical zombie horror–themed single-player campaign, two multiplayer modes, and cosmetic additions to the environments and characters. Set in an alternate timeline from the base game's story, the plot follows returning protagonist John Marston, a former outlaw who sets out to find the cause of and possible cure for a zombie plague that has infected his wife and son. Marston liberates towns overrun by the undead and assists non-playable characters with side quests along the way.
