EA/DICE have announced a further 3 DLC packs for Battlefield 3. The first one, named 'Close Quarters', will be released in June.
This new pack is built on CQB action, and apart from new warzones, it also will contain new weapons, dog tags and assignments.
The fall of 2012 will bring 'Armored Kill' (not to be confused with BF2's Armored Fury DLC), a pack based on vehicle warfare and will bring a mobile artillery and the largest map ever made.
Although, in our opninion this will have to be seen first. The 3rd pack named 'End Game' is left in mysterious clouds and nothing is known yet about this DLC.
When there is more known, we will be here to keep you informed!
