🎮 Play Marine Boy Online (Arcade)

Marine Boy is a classic 1982 Arcade action game developed by Orca. Playing as a deep-sea diver, your goal is to navigate through perilous ocean waters to reach the mermaid waiting at the bottom. Along your descent, you must carefully manage your oxygen gauge while rescuing smaller mermaids and dolphins for bonus points.

How to Play

You must reach the end of the stage before your oxygen runs out. The ocean is filled with hostile sea life like sharks, piranhas, and octopuses. Defend yourself using your retractable harpoon punch to strike enemies in your path. Use the Arrow Keys to swim in all directions, press Z or X to attack with your harpoon, and use Shift/Enter to insert coins and start.

Tips

• Watch the Oxygen: Your air supply constantly depletes, so prioritize downward progression over hunting every enemy.
• Master the Movement: Your diver has a noticeable turning radius when swimming, making sudden direction changes tricky. Plan your path through the sea creatures carefully.
