Pre-order the Battlefield 3: Limited Edition from Game or Gamestation and you'll get the Physical Warfare Pack.
This includes the Type 88 light machine gun with bipod "for superior firepower and total zone control". Also included is the SKS sniper rifle flash suppressor that provides increased stealth abilities for Recon soldiers. And finally, the "lethal armour-piercing" flechette ammo for the DAO-12 semi-automatic shotgun "that is sure to tear through anything in its path".
The pack also includes the already announced Battlefield Back to Karkand day one expansion pack, which features maps from Battlefield 2, including Strike at Karkand, Gulf of Oman and the Sharqi Peninsula, recreated using the Frostbite 2 engine. This is included in all Limited Edition purchases.
