Neptune's daughter has been captured by an evil Sea Serpent, and your aquaman's mission is to swim through the underwater caverns to rescue her, armed with a harpoon with which to shoot away the sucker plants blocking his way and kill the octopuses and other sea monsters.

What the other monsters are like I never discovered, as my skill with a joystick was not sufficient for this game, but I'm getting better - I'll rescue the fair maiden one of these days!

It's a challenging and quite addictive game, with good graphics and reasonable sound effects. I would have preferred, though, to return to the start of the current screen on losing a life instead of going right back to the start of the game every time. High scores can be obtained quite easily by standing your ground and shooting octopuses, but that's not really the point of it; the challenge is to complete the mission, not to score thousands of points without going anywhere.

The high-score table is a definite weak point. Otherwise, though, it's a well written and constructed game.
