Climb aboard a submarine and collect treasure hidden away well deep below sea level. Bring them home to your mothership and spend your earnings on fuel, repairs and lots of upgrades.
Use the arrow keys to control your submarine.
Spacebar to launch the torpedos (you must buy them fist).
If your submarine is destroyed, clicking Continue does not mean that you have to start again, only your score resets and you lose one half of your money.
