Escalation contains 5 all-new maps, including four multiplayer maps and an "epic" Zombies experience with all-new playable characters. The multiplayer maps include:
* Hotel, which is set on the roof of a Cuban luxury hotel and casino against the vivid backdrop of old Havana.
* Convoy, which delivers intense, close-quarters combat at the scene of an ambushed US military convoy.
* Zoo, a level in an abandoned Soviet Russian Zoo, with danger at every turn
* Stockpile, which pits players in a remote Russian farm town housing secret WMD facilities.
* Escalation, which features a unique Zombies experience which will be revealed later.
The PC and PlayStation 3 versions will be released at an unannounced future date.
