Activision has released a video with details of the first downloadable map pack to Call of Duty: Black Ops. It is called First Strike, and will be available on Xbox 360 on February 1. More details to come for PS3 and PC.

First Strike contains 5 incredibly diverse maps spanning the globe; featuring 4 multiplayer maps and a new Zombie experience. Includes “Berlin Wall”, allowing combat on both sides of the imposing wall; “Discovery”, a desolate, frozen German outpost in the Arctic; “Kowloon”, battle in the rain along the rooftops of a towering Chinese sprawl; “Stadium”, an intense locale with a pro hockey arena backdrop; and “Ascension”, where you fight zombies in a Soviet launch facility.

The map pack will cost you 1200 Microsoft Points. Check out the video for a quick review of the new maps.
