Just after the release of the Close Quarters DLC, DICE has announced the Armored Kill DLC. This DLC looks to put the 'field' back in Battlefield with more of a focus on vehicles and what they claim will be "the biggest map in Battlefield history!".
Armored Kill will be released in the Summer of 2012, and will focus on armored warfare, with large, open maps, new vehicles, including new main battle tanks.
