The Battlefield army is over 12 million strong and growing every day as Battlefield 3 and its first expansion, Battlefield 3: Back to Karkand, continue to recruit gamers around the world with its sandbox gameplay and state-of-the-art technology. DICE, an Electronic Arts studio, will keep the action coming throughout the year with three new themed digital expansion packs that will introduce new modes, unique environments and more ways to wage all-out-war. Powered by the Frostbite 2 engine, the next expansion packs are: Battlefield 3: Close Quarters in June, Battlefield 3: Armored Kill in the fall, and Battlefield 3: End Game in the winter.
