Two players take control of Captain Ahab and the Great White Whale to defeat their enemies and earn their vengeance for past wrongs. The Whale is responsible for dodging obstacles (be it docks or undersea mines) and regaining life (by eating fish and tasty humans). Ahab, however, is responsible for defending both the whale and himself from damage by spearing enemy gulls and spearing down cannon balls. In brief, the two players must cooperate if they are to survive.
