Play Ghost Recon, win a car

In a large tournament, over Xbox Live, Ghost Recon: Advanced Warfighter players will be able to fight for the title of the greatest GRAW team around and a shiny new Dode Caliber. Definately cool news. All you have to do to enter is stop by a Best Buy and fill out a form, simple as that. Whether you're good enough to win is another question.
