During the World War 2, the British and the USA are at war. Each country didn't want the others to win. The British sent in their whole force, while the Americans sent in their best soldier. He is a super soldier, which no one can match in the battlefield. Eradicate all of your enemies. You would start with a basic gun and a few grenade. You can pick up some ammo for better guns, but when your ammo runs out then you would be back with your basic gun. Either way, you need to keep on fighting till you your last breath.
