My name is McArra, and I serve in the elite pacification forces. My objective is to locate and eliminate the nuclear submarine U-5544, which has disrupted the balance of power between Earth's two strongest military factions. The operation is called Cephalopod, and I understand you're interested in assisting me with this "simple" task. Initially, we'll be deployed near the island where the submarine is moored, waiting for further instructions. We'll swim toward the shore, and from there... our choices will determine the outcome. "Navy Moves" is a one-dimensional side-scrolling shooter and the follow-up to "Army Moves," featuring the same gameplay style.
