Battlefield 3's Physical Warfare Pack grants you instant access to the powerful DAO-12 shotgun, if you haven’t unlocked it already. It also features custom flechette ammo for the DAO-12, a flash suppressor for the SKS sniper rifle, plus the Type 88 Light Machine Gun.
What was at first a pre-order exclusive is now available for PS3 owners for free, thought it will not retain its exclusivity and be available for PC and Xbox 360 players as well.
