Black Ops: Escalation out now!

An official release from Treyarch, the map pack is out now on Xbox Live:

Call of Duty: Black Ops Escalation is now available for download on Xbox LIVE.

It’s packed with four brand new multiplayer maps and a new zombie map. Take on the opposition in a deserted Zoo. Battle through the casino in Hotel. Use the landscape to your advantage in Convoy. Take the battle into the Soviet heartland in Stockpile. And when you’re done… get ready to take on the zombies in the frozen wasteland of Siberia with an all-star cast of characters in Call of the Dead.

On top of all of that, this weekend is going to offer Double XP to everyone who plays. Get Escalation, hop online, and start rocketing up the ranks.

You can get the map pack for 1200 MS Points, or $15.
