There's a new trailer out today for Battlefield 3 that offers a look at the upcoming first post-Back to Karkand multiplayer DLC pack, Close Quarters. It's the first of three themed expansions. This one focuses entirely on infantry-only showdowns, with the new trailer offering a look at the pack's Ziba Tower map.
Electronic Arts revealed its plans are for the future of Battlefield 3 at GDC last week at an event early in the week. Close Quarters is coming in June, followed by the vehicle-centric Armored Kill pack and, eventually, the mysteriously titled End Game. That last one is set for "winter," which could mean very late this year or even early next year.
