The guys over at Activision also have a launch trailer for their year's big shooter, Modern Warfare 3. Like the Battlefield 3 launch trailer you'll see a heap of excellent single player campaign sequences, but the horrible voice casting and dated graphics might send you straight back to watch that instead. MW3 hits Steam on November 9.
finished the campaign, was very good but very short - can be done in just over 4hrs and like battlefield they went with push button action sequences - they annoy the hell out of me.
