Call of Duty: Black Ops is the latest game in the annually-updated series. First Strike is the new DLC for said game, and it’s out now on the Xbox 360. PS3 and PC gamers will have to wait a little longer.

This video shows a preview for the Black Ops First Strike DLC, which contains five new multiplayer maps, including one in which the zombie hordes make a return.

If you’ve played Call of Duty: Black Ops through already and now need something new to keep your interest, then the DLC is a good option. Unfortunately it isn’t free, costing around $15.

The maps in Black Ops First Strike all look pretty good, and in particular Berlin Wall, which sees you facing off on either side of the infamous barrier between east and west Germany.
