An early listing of the Modern Warfare 2 "Stimulus Package" on the Xbox Live Marketplace web site reveals it is comprised of five maps, two of them old favorites from the first Modern Warfare.
The Stimulus Package isn't due out until March 30 on the Xbox 360 (dates for the PC and PS3 versions are still TBA). Here's the description from its Xbox Live listing, which was live as of 3 p.m. U.S. Mountain Time.
The best-selling Xbox 360 game of all-time just got bigger, with more epic multiplayer content, first on Xbox LIVE! The Stimulus Package delivers 5 additional action-packed multiplayer maps featuring a variety of locations: "Bailout," a multi-level apartment complex; "Storm," an open industrial park littered with heavy machinery; "Salvage," a snowy junkyard fortified by stacked debris and crushed cars. Two legendary fan-favorites from Call of Duty 4: Modern Warfare return, including "Crash," [pictured above] a war-torn urban environment; and "Overgrown," which features a massive dry creek bed. There are no refunds for this item. For more information, see www.xbox.com/live/accounts.
It'll weigh in at 328 MB. No word on pricing yet, and you can't queue it up for download, either. It asks you for a redeem code.
