Sea Wolf is an action-adventure game where you control a submarine, navigating through underwater caverns to rescue a captured crewmate. Your mission is to avoid deadly sea creatures, navigate treacherous terrain, and overcome obstacles while trying to reach the crewmate before time runs out.
Gameplay involves moving your submarine left and right, shooting missiles at enemy targets, and collecting power-ups to increase your chances of success. As you progress through the levels, the challenges get tougher, with more aggressive sea creatures and increasing water pressure that can damage your submarine.
