In case you didn't believe DICE when the studio informed us that Battlefield 3's destruction engine would be more destruction-ey in the upcoming "Back to Karkand" expansion, the latest trailer should convince you. Just look at all that debris!
Built on the cutting-edge Frostbite 2 technology, Battlefield 3 aspires to be DICE's best shooter and biggest launch yet. Expect improved graphics, louder explosions and more smithereens. So many smithereens.
