Battlefield 3 has a new trailer for its new level. Lots of awesome is viewable and playable so bloody well enjoy the trailer and then enjoy the map, which is described below.
"Close Quarters: In Battlefield 3: Close Quarters, players are dropped into a frantic, infantry-only theatre of war. Frostbite 2 high definition destruction makes the environment come alive as everything from furniture to plaster gets shot to pieces. Players will feel the intensity of the world exploding around them as rubble and broken pieces pile up on the floor, while tight level design and vertical gameplay create a highly competitive environment. Battlefield 3: Close Quarters also introduces new weapons, assignments and unique dog tags to bring back to the base game."
