Red Dead Redemption: Undead Nightmare - Xbox One
Red Dead Redemption: Undead Nightmare is a DLC for Red Dead Redemption but was also released in retail as a standalone title that does not require the original game to play. It stars the game's protagonist outlaw John Marston who wakes up one morning and finds a plague has swept across the West. Zombies have overrun the towns and outposts of the American frontier, and John Marston must attempt to save his family and survive long enough to find a cure.
It contains new single-player missions with additional challenges, eight zombie characters, zombie animals and mythological creatures, new events, new weapons, and new multiplayer co-op missions and competitive modes.
