Modern Warfare 2 doesn't come out until November 10, but buzz is already building around the Call of Duty sequel. A new teaser trailer hit the webs last week with a paltry 15 seconds of footage, revealing standard military shooter fare (jets, land combat, explosions) as well as some surprises in the form of sharks and snowmobiles. Sounds to us like Infinity Ward is taking a page from Tomb Raider (leading lady Lara Croft has all but mastered the art of shark-fighting and snowmobile-riding). Check out the trailer below!

The trailer also hints at more Modern Warfare 2 content to debut during the NBA Eastern Conference Finals on May 24. That, in addition to new information surfacing in next month's Game Informer and the upcoming E3 video games conference, will no doubt mean more details about the shooter Activision's been keeping under tight wraps.
