This news comes from a flyer that was posted on an Australian game retail website earlier today. Since then the flyer has been taken down but it said “Call of Duty: Black Ops – Escalation – 5/3/11 – Seize the Zoo, Take the Hotel, Secure the Convoy, Raid the Stockpile and Survive the Call of the Dead.”
From the looks of it the next map pack will have four multiplayer maps and one Zombie level just like the last DLC First Strike. Check back at onPause, I bet more will be revealed very soon.
