Back to Karkand is a massive themed expansion pack. It features four of the most loved Battlefield maps ever, boldly reimagined with the power of the Frostbite 2 engine. It also gives you new weapons, vehicles, dog tags, and persistence in the form of all-new "assignments" to carry out on the battlefield.The maps included are Strike at Karkand, Gulf of Oman, Sharqi Peninsula, and Wake Island. All have been redesigned from Battlefield 2 as a return years later, changing the scenery and adding the powerful destruction that Frostbite 2 brings to the game.
