This time it deals with combat. You'll see the Engineer sentry turret, a new Vanguard power called Nova, the newly upgraded Overload, a few of the different melee attacks, and more. It's good stuff, just ignore the sorta redundant Collector's Edition information that fills up the first minute and a half or so. Mass Effect 3's release date is approaching fast. It hits shelves on March 6, 2012.
