The latest Call of Duty: Black Ops map pack, 'Annihilation', is now available for purchase on the Xbox Live for 1200 MS Points (that's £10.28).
The pack includes four competitive multiplayer maps - Hangar 18, Drive-In, Silo and Hazard - as well as a fresh Zombies map called Shangri-La.
Treyarch studio head Mark Lamia said of the DLC: "With Annihilation, Black Ops fans will get four exciting and unique multiplayer settings with Hangar 18, Drive-In, Silo and Hazard.
"Players will also enjoy an all-new Zombies experience, Shangri-La, an exotic and mysterious map filled with deadly traps, dark secrets and innovative gameplay that will challenge even the most daring Zombie hunters."
The map pack is scheduled for release on PS3 and PC at a later date, but Activision hasn't specified when.
