Just as we’re talking about the Call of Duty series, Activision has announced Escalation, the next game add-on for Call of Duty: Black Ops will be available first to Xbox LIVE members on Tuesday May 3rd.

Escalation contains 5 all-new maps featuring 4 Multiplayer maps and an epic Zombies experience with all-new playable characters.  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 but who cares…it’s more Zombies!  You all can expect to pay 1200 Microsoft Points for this so start saving.
