If you own Battlefield 3 and haven't picked up the Close Quarters DLC pack, you can apparently now do so for free on PS3 and Xbox 360 - just visit the in-game store. PC owners will have to be slightly cannier by typing "BF3E3" into Origin's File>Redeem Code panel.
I personally haven't played Close Quarters' selection of intimate maps, but have heard some mixed reports. Either way, it's free over the coming week, so you might as well grab it and let me know. [Battlefield Official Blog, credit to Dancorp @ HUKD!]
