Call Of Duty: Black Ops - First Strike Map Pack Trailer

Treyarch has released a second video previewing the First Strike map pack for Call of Duty: Black Ops. This trailer shows in-game footage of the new maps set to the Rolling Stone's "Gimme Shelter."

The biggest difference between this trailer and the previous video is that this one actually shows the new zombie co-op map. "Ascension" takes place in at a shuttle launch center. You'll need to fend off zombies inside and outside of the facility. At one point you'll get to ride some sort of rocket-propelled platform.

First Strike will hit Xbox Live on February 1st and cost 1200 MS Points ($15). The DLC is a timed exclusive for the Xbox 360. Though the PS3/PC release dates haven't been confirmed yet, gamers on both platforms should expect to wait about a month.
