Call of Duty: Modern Warfare 3 has just added some star power to its marketing Blitz (at least on Xbox). Sam Worthington, Jonah Hill and Dwight Howard are featured in the latest video ad campaign for the mega-hit video game. Called “The Vet & The n00b Official Trailer”, this new trailer shows the Hollywood and TV-show stars as Modern Warfare 3 players. From New York to Peris, to Berlin, they get into hot action and by the end of it, one comes out transformed. If you don’t know, the game is coming out this Tuesday, but someone could just not wait and got it on eBay for $1700+ – crazy.
