Publisher Activision is contributing to the already crowded month that is May with the release of the second map pack for Call of Duty: Black Ops, dubbed Escalation. Per exclusivity agreements, it’s hitting Xbox Live first, on May 3 to be specific. While a release will follow on PC and PS3 at a later date, the company isn’t ready to say when.

It ushers in four all-new multiplayer maps — Zoo, Convoy, Hotel and Stockpile, along with a “Zombies experience like none before it.”
“In crafting the Escalation multiplayer maps — Zoo, Convoy, Hotel and Stockpile — the team developed them to be distinct experiences in their own right, giving players the variety they crave in both setting and gameplay,” said Treyarch Studio Head, Mark Lamia. “And I don’t want to spoil any surprises for Zombies fans, but Call of the Dead takes it to a whole new level.”
