[Update 11:40] Activision PR has responded to our inquiry: "No comment at this time. We'll loop you guys in when we have something."
[Original Story] An advertisement from an Australian retailer has leaked the next bit of downloadable content for Call of Duty: Black Ops, VG247 reports. Titled "Escalation," the pack includes five maps. The flyer teases them as: "Seize the Zoo," "Take the Hotel," "Secure the Convoy," "Raid the Stockpile," and "Survive Call of the Dead."
Like First Strike, Escalation will be a timed exclusive on the Xbox 360 as part of Activision's deal with Microsoft, with PC and PlayStation 3 versions coming afterwards. The flyer stakes the date as May 3, 2011, but since it comes from an Australian retailer we could see different release dates in the U.S. and Europe.
We've contacted Activision for official word on the DLC, and will update as more information becomes available.
