Confirming a recent leak, Activision has officially announced the upcoming 'Escalation' map pack for Call of Duty: Black Ops.
A timed Xbox 360 exclusive, the DLC will launch for Microsoft's console on May 3. It'll feature four new competitive multiplayer maps as well as a fresh Zombies level with new playable characters.
Activision said: "In multiplayer, battle it out in Hotel, on the roof of a Cuban luxury hotel and casino against the vivid backdrop of old Havana; Convoy delivers intense, close-quarters combat at the scene of an ambushed US military convoy; Zoo takes you on a wild ride in an abandoned Soviet Russian Zoo, with danger at every turn; Stockpile pits players in a remote Russian farm town housing secret WMD facilities.
"For Zombies fans, 'Escalation' features a unique Zombies experience."
There was no pricing information, but we'd expect the pack to cost 1200 Microsoft Points (about £10.28).
