Call of Duty: Black Ops new downloadable map pack entitled 'Escalation' will launch worldwide, first on Xbox Live on May 3, 2011.
Escalation contains 5 all-new maps; featuring 4 Multiplayer maps and 1 Zombies map 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. We can't wait to take the wraps off of our new Zombies map, Call of the Dead, a very special creation for all Zombies fans.
