The Black Ops - Rezurrection DLC was first released to Xbox 360 (in customary Call of Duty fashion) back in August. For players who have stuck with PS3 or PC, the somewhat new content will be arriving later this month, on September 22.
Rezurrection is the fourth Black Ops DLC pack to be released, and if you haven't been keeping up, takes players to the moon to fight the undead in outer space. SPACE! Additionally, the DLC includes four "remastered" Zombies maps from World at War -- Nacht der Üntoten, Verrückt, Shi No Numa, and Der Riese -- and an "enhanced" Zombies soundtrack.
As always, the add-on is priced at $15 for all platforms.
