The Battlefield Blog now offers a new Gulf of Oman Gameplay Trailer from Battlefield 3 showing off more of the upcoming Back to Karkand expansion pack for the military shooter sequel. The clip highlights new vehicles in the add-on. "I wanted to complement what we already have in the base game, plus I wanted to bring back some of the classic vehicles from Battlefield 2 that we know players loved, such as the Short Take-Off/Vertical Landing fighter jet and the desert buggy. In today’s trailer, you can also get a first glimpse of a hitherto unannounced fourth vehicle bound to strike fear into the very hearts of the enemy. See if you can spot it!", said Back to Karkand Lead Designer Niklas Fegraeus.
