Call of Duty: Modern Warfare 2 continues the gripping and heart-racing action as players face off against a new threat dedicated to bringing the world to the brink of collapse.

All PC versions of Call of Duty: Modern Warfare 2 will be powered by Steamworks, providing gamers with auto-updating, anti-cheat technology, Steam Achievements, and the recently introduced Steam Cloud.

Featuring the first new multiplayer maps for Modern Warfare 2, the stimulus package will be available first on Xbox Live on March 30th.

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," a war-torn urban environment; and "Overgrown," which features a massive dry creek bed.

The second pack of new multiplayer maps from Call of Duty: Modern Warfare 2, will hit first on Xbox LIVE on June 3rd with the release of the Call of Duty: Modern Warfare 2 Resurgence Pack. Featuring five maps, the Resurgence Pack follows on the heels of the record-setting Call of Duty: Modern Warfare 2 Stimulus Package of maps.  

Additionally, to celebrate the upcoming release, Infinity Ward will host two Double XP weekends.  The first Double XP will take place beginning Friday, May 28, and the second will follow on Friday, June 4.
