As if Call of Duty: Black Ops wasn't a fully loaded game already, the people at Treyarch are set to deliver the first batch of DLC add-ons for the game Feb. 1. The DLC pack titled First Strike will include five brand new levels that include four multiplayer maps and one zombie level.

The four new multiplayer maps are Kowloon (which is based on the Kowloon City level from the game and will include zip lines for players to use to get around faster), Discovery (which will be a large area in the Arctic that is divided by a large chasm and will feature collapsing snow bridges), the Berlin Wall (which will be the largest map in the pack and looks to be a promising area for snipers and long-range gunners), and Stadium (which is the smallest map and is great for all you run-and-gun close-quarter combat players).

As of yet, we haven't seen much of the new zombie level, Ascension, but expect more news on this as the release date approaches. The First Strike DLC pack will be available Feb. 1 for the Xbox 360 and will cost 1200 Microsoft Points. No news yet on if and when it will be available for the PlayStation 3 or cost.
