As we noted a couple of days ago, Activision and Infinity Ward were just about to name and put a date on the first DLC pack for Call of Duty: Modern Warfare 2. Well, now they have; the map pack will be called Stimulus Package (we see what they did there) and will be out on March 30.
Also, if you don't have a Gold account for Xbox Live you will be able to play the game online between March 12 and 15 to get a taste for it well in time before the map pack is out. Clever.
