Activision's first DLC pack for Modern Warfare 2 is due to hit Xbox Live today.
The Stimulus DLC includes five new maps: Bailout, Salvage, Storm, and classic maps Crash and Overgrown.
The DLC is exclusive to Xbox 360 for now, but will be coming to PS3 and PC down the line.
According to Infinity Ward's Robert Bowling, gamers will also be getting:
Originally planned to do it this weekend, but we've decided to throw the Double XP switch early when the new maps hit. So jump online with the new DLC and check out the two new DLC specific playlists.
Stimulus and Hardcore Stimulus Playlists
These two playlists are 100% dedicated to the new maps, and are Double XP enabled. So jump on and experienced the new DLC you downloaded, get double XP, and experience all your favorite gametypes along with some hardcore variants of them.
Ranger maps added to HCHQ
We're adding a few maps to the Hardcore Headquarters Pro playlist on Xbox Live, allowing you now play all the Ranger maps in this gametype, something I know a lot of users have been asking for! These maps include Highrise, Invasion, Skidrow, and Terminal.
Alongside the DLC, but something ALL of our users will get, is a title update for Modern Warfare 2. Included in this update is support for the DLC (if you choose to purchase it), as well as some tweaks to the One Man Army perk, some matchmaking updates that will help our international users find more locally hosted games thanks to how ping is now sorted, and various other code updates that will help improve the overall quality of multiplayer on Modern Warfare 2.
Bowling added: "There is no exact time you can expect all this, I'd say early morning when traffic is at its lowest, but by the time you wake up and get online I'm sure it will be available to most of you on March 30th! See you online all this week!"
