Sirens blare through the submarine as your crew dives beneath the waves. Somewhere in the darkness, the enemy sub is hunting you—and you’re hunting them.

Face off in a tense real-time battle of wits, teamwork, and nerves. Each team secretly plots its movements through the ocean while frantically listening for clues about the enemy’s position. The Captain steers the sub, the Engineer manages critical systems, the Radio Operator tracks the enemy, and the First Mate fires weapons. Orders are shouted and tension builds as both crews race to locate the other sub first. Then —contact! Arm the torpedoes! Deploy the mines!
