Here's a new trailer showing off the "deadly" Battlefield 3 Physical Warfare Pack items in action. As noted on the Battlefield Blog, the Physical Warfare Pack for the upcoming military shooter sequel contains the DAO-12 semi-automatic shotgun, Type 88 Light Machine Gun, flechette ammo for the DAO-12, and a flash suppressor for the SKS sniper rifle. And while this is a preorder bonus at select retailers and at Origin for the PC digital download version of Battlefield 3: Limited Edition, they also offer this reassurance: "At a later date, we will unlock all of these items to all players of Battlefield 3 at no extra charge."
