Following Revolution and Uprising , Call of Duty: Black Ops II will get its third downloadable content pack starting July 2, 2013 on Xbox 360. Priced at $15 (1200 Microsoft Points) without a Season Pass, this add-on has another four multiplayer maps and "Buried" for Zombies.
"Cove" is set on an island in the Indian Ocean; "Detour" has an East Coast waterway's destroyed suspension bridge; "Rush" takes close-quarters combat to a paintball arena; and "Uplink" reimagines Black Ops' multiplayer map "Summit."
The new Zombies experience, "Buried," occurs in an Old West mining town and adds the Ray Gun Mark II for your undead-slaying pleasure. Vengeance will of course be coming to other platforms at a later date, though we do not know the schedule yet as per usual.
