Infinity Ward's Robert Bowling dropped the news via Twitter, saying that over one million users "helped the Modern Warfare 2 Stimulus Package break day 1 & week 1 download records on PSN!"

It is not clear how many users grabbed the content in the first 24 hours or within the first week, but it has sold at least one million digital copies at $15 each.

On the Xbox 360, over one million users grabbed the pack in the first 24 hours with an additional 1.5 million snagging it in the first week. The "Stimulus Package" DLC includes five multiplayer maps, two of which come from Call of Duty 4: Modern Warfare.

A second DLC pack, the "Resurgence Pack", is on the way. It include another five maps (two from CoD4) and will be released first on the Xbox 360 for $15. PS3 and PC versions (via Steam) will follow, most likely one month after the June 3 Xbox 360 release date.
