Just a note to let you know that the Call of Duty®: Black Ops Escalation content pack is now available for download from Steam for Windows PC.

Escalation features four new multiplayer maps and an unprecedented Zombie experience, including famed director George A. Romero, Robert Englund, Sarah Michelle Gellar, Michael Rooker and Danny Trejo.

The Escalation content pack’s new multiplayer maps include:

· “Hotel,” where players battle it out 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 U.S. military convoy

· “Zoo,” which sets gamers on an eerie ride through an abandoned Soviet Russian Zoo with danger at every turn

· “Stockpile,” which pits players in a remote Russian farm town, housing secret WMD facilities

· “Call of the Dead,” Escalation’s Zombie experience that assembles a zombie-carnage dream team to fight against a new and undefeatable zombie horde menace, all set in the dark, ice-covered isles of Siberia

To celebrate the release of Escalation on Windows PC, Treyarch is hosting a Double XP weekend starting Friday, June 3.
