Wooosh! Bang! This new trailer for Battlefield 3 is all about blowing things up and showcasing the incredible possibilities for destruction in the Frostbite 2 engine. Rockets fly, helicopters crash and buildings come tumbling down in a giant tribute to the art of demolitions. Check out the ground at 0.43, is that some kind of earthquake? A clue to the single player story? Or have Battlefield 3's weapons just become so powerful that they can actually be mistaken for natural disasters?
