Activision and Treyarch have officially confirmed the second downloadable map pack for Call of Duty: Black Ops, the Escalation DLC, which was leaked last week and will be arriving at the beginning of May.

Call of Duty: Black Ops has been selling a huge amount of copies all over the world, and the first map pack released for the game back in February, the First Strike DLC, managed to sell over 1.4 million copies in just 24 hours.

Now, Activision, the game's publisher, and Treyarch, the developer, have confirmed what was leaked last week, that the game's second DLC is called Escalation and will arrive at the beginning of next month.

Just like First Strike, the DLC will include four new maps for the regular multiplayer modes, as well as a new scenario for the Zombie cooperative mode.

"In multiplayer, battle it out in Hotel, on the roof of a Cuban luxury hotel and casino against the vivid backdrop of old Havana; Convoy delivers intense, close-quarters combat at the scene of an ambushed US military convoy; Zoo takes you on a wild ride in an abandoned Soviet Russian Zoo, with danger at every turn; Stockpile pits players in a remote Russian farm town housing secret WMD facilities. For Zombies fans, 'Escalation' features a unique Zombies experience," Activision revealed.

Also keeping in tradition with previous map pack for Call of Duty games, the Escalation DLC will be released as a timed exclusive for the Xbox 360 console, on May 3.

After the deal with Microsoft wears off, the DLC will then appear for platforms like the PlayStation 3 and PC, usually after a month or so.

"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."

Expect the new map pack to cost 1200 MS Points or $15 when it appears on online services like Xbox Live, the PlayStation Network or Steam.
