Everybody loves Call of Duty games online.  There are thousands of people playing online at any given time and March 19th will be another reason to clock some more hours.  The map pack will have 3 new competitive multiplayer maps (Nightfire, Station, and Knee Deep) and one new nazi zombie mode that takes place on the asylum level.  No price yet on this map pack but 10 dollars sounds about right given past packs.  Also, this date does not apply to the PC version as there is no date set at this time.  Enjoy the video!
