First, the details on Back to Karkand for those not in the know, straight from DICE:

“Back to Karkand is our first expansion pack for Battlefield 3. It features four legendary Battlefield 2 maps reimagined in the Frostbite 2 engine, with enhanced levels of destruction.

“More than just a map pack, Back to Karkand also features 10 new weapons to extend your arsenal (you can bring these new weapons back to the base game maps), three classic vehicles from Battlefield 2, including the STOVL fighter jet (excellent for hovering and capturing bases), Desert Buggy, and and APC, five new dog tags, and an added layer of persistence with the all-new Assignments you need to complete to unlock new weapons.”

Here’s that fresh new video for one of Back to Karkand’s maps:
