The launch trailer offered teasers of how the up-rezzed environments from previous Battlefield games would look in the upcoming Back to Karkand expansion pack, but these screens show them in all their Frostbite 2 glory. Back to Karkand will also include new dog tags, new Xbox Live achievements/PSN trophies, three new vehicles and 10 iconic Battlefield weapons. It'll also introduce a new persistence system where you'll complete assignments to earn rewards. Back to Karkand rolls out in December.
