Black Ops' Escalation add-on slams PSN June 10

In a post on the PlayStation Blog, Activision said the $15 Escalation DLC for Call of Duty: Black Ops will arrive on the PlayStation Network next Friday, June 10. The content--which debuted in May for the Xbox 360, and yesterday for the PC--is composed of new multiplayer maps and a new zombie mode addition.

The Escalation pack sports four multiplayer maps: Hotel, set on top of a luxury hotel and casino in old Havana; Convoy, which offers up close-quarters combat when a US military convoy is ambushed; Zoo, set in a derelict Soviet-era animal park; and Stockpile, which is set in a small Russian town that contains secret facilities housing weapons of mass destruction.

The downloadable add-on also features a "Call of the Dead" level. The zombie-slaughtering co-op level will feature a storyline inspired by famed horror director George A. Romero (Night of the Living Dead) and features a '70s movie aesthetic that sees four action stars fending off hordes of undead around a ghost ship. It will feature the voices and likenesses of actors Robert Englund (Nightmare on Elm Street), Sarah Michelle Gellar (Buffy the Vampire Slayer), Michael Rooker (The Walking Dead), Danny Trejo (Machete), and Romero himself.

To celebrate the arrival of the Escalation content, Activision is granting PlayStation 3 Call of Duty gamers double XP through June 12. For more on the title in question, check out GameSpot's review of Call of Duty: Black Ops and Starting Block video feature, embedded below.
