You play a soldier called Nomad. You and three soldiers look for missing people on an island. You find that Koreans attacked the island. America attacks the island. In the middle of the fighting, aliens come out of a mountain. Aliens then make a cold sphere (ball shape) on the island. America shoots a nuke at the sphere. The sphere becomes bigger, because it took the energy from the explosion. You then fight a big alien on a big ship.
