Vietnam, 1967. You are Specialist Heavy Gunner Grant of the 6th Platoon US Marine Corps. Weeks earlier on a routine search and clear mission, members of your platoon were ambushed and taken prisoner by the Black Skulls, an elite North Vietnamese unit under the command of Colonel Trung also known as the ?butcher of Bac Ninh?. Your mission is to find the hidden POW camp and rescue your buddies?and perhaps exact a little revenge along the way.
