Activision announces Call of Duty: Modern Warfare 2 is now available in stores. Interestingly, the version purchased through Steam will not unlock until Thursday night, presumably some sort of concession to retail. Also, there's a Call of Duty: Modern Warfare 2 video interview on GameVideos talking about the game with Infinity Ward's Robert Bowling and there are a bunch of videos on GameTrailers: Hornet's Nest Gameplay Part I, Hornet's Nest Gameplay Part II, Favela Gameplay Part I, Favela Gameplay Part II, Wolverines Gameplay, No Russian Gameplay HD, Third-Person Multiplayer Gameplay, Multiplayer Killstreak, Spec Ops AC-130 Gameplay, and Spec Ops Defend Gameplay. Here's word on the game's release:

Picking up following the historic events of Call of Duty® 4: Modern Warfare®, Modern Warfare 2 completely immerses players in one of the most intense storylines, filled with unexpected plot twists and death-defying battles set in exotic locales across the globe. As gamers fight to save the world from annihilation, the soundtrack of Academy Award®, Golden Globe® Award and Grammy® Award winning composer Hans Zimmer sets the dark and ominous tone for a truly cinematic gaming experience. Modern Warfare 2 marks the first time that the legendary artist has scored a video game.

Delivering the complete package, in addition to the heart-racing intensity of the single player campaign, Modern Warfare 2 also offers an entirely new gameplay mode, "Special Ops," which supports 2-player co-operative play via online or split screen dropping gamers into a surplus of time-trial and objective-based missions. As players rank-up, ever challenging missions are unlocked, including highlights from the single player campaign, fan favorites from Call of Duty 4: Modern Warfare and all new, exclusive missions. While, the all-new Multiplayer mode raises the bar even higher from the world-record setting online play from its predecessor delivering new capabilities, customization, gamestates and modes, including customizable killstreaks, accolades and new create-a-class features.
