- "Makin Atoll, little more than sand, trees and a small Japanese military base. Miller's reconnaissance team landed there almost a week ago, since then we've heard nothing. The waiting's over. We're going in. For all we know they're already dead. If what little we know about the Japanese is true, it might be better if they are."

Pvt. Miller from the 2nd battalion of the Marine Raiders, Carlson's Raiders, is held captive by the Japanese forces, and witnesses his comrade, Pvt. Pyle, being tortured and then murdered. Miller is saved by Cpl. Roebuck, who then says "We're gonna make 'em pay for what they've done.".
Miller and the rest of the squad secured the village by killing the Japanese in the area. After the first part of the village is secured the team heads for second squad's position. Along the way, the team faces banzai charges and booby traps. Miller eventually makes his way through the island to rescue the second squad who are pinned down on the beach.
Miller then proceeds to blow up the Japanese bunker, crippling their operation there. While making one's way to the boat, Miller is attacked by an enemy banzai wielding a katana and is wounded, but is then saved by Sgt. Sullivan when he shoots the Japanese soldier with an M1911 . Ultimately, Miller is dragged to the boat and witnesses a large explosion, which destroys the base.
