The second installment of Call of Duty: Black Ops' downloadable maps will release on May 3, but today you can get a quick overview on what you may (or may not) be purchasing come the DLC's release.
The "Escalation" map pack comes with five brand new maps, one of which is a "Zombies" map. It will drop on the Xbox 360 first with a PlayStation 3 release sometime later. Expect to pay the usual price point at this rate too.
