Red Dead Redemption 'Undead Nightmare' DLC Trailer Features Wild West Zombies, Undead Bears

No matter the era, rest assured that zombies want to eat your brains. Rockstar has just released the first trailer featuring the upcoming downloadable content pack for Red Dead Redemption featuring the brain-craving monsters, dubbed "Undead Nightmare."

The "mostly single-player" DLC features a new campaign following Redemption's hero John Marston as he searches for the cure for the "highly infectious zombie plague" that has infected the Wild West. Along with undead humans, Marston will have to contend with zombified animals lurking throughout the frontier -- like a giant freakin' bear.

Red Dead Redemption's previous DLC packs, 'Legends and Killers' and 'Liars and Cheats,' focused on the game's multiplayer component.

According to the short, debut trailer, Undead Nightmare will launch "very soon." The content will be made available on the PlayStation 3 and Xbox 360 for $10 (800MS Points).
