Tomahawk Missile

While visiting the Lunar Sea of Zion on one of the seven moons of Zolarin, your submarine "Marauder" has come under attack by nuclear weapon wielding Zionites. In addition to bombing you, they are also using their powers to evaporate the waters of the sea. But you can fight back by launching your death dealing tomahawk missiles.

Tomahawk Missile is yet another Galaxian style shoot-em-up, but with a nautical theme. You control a slow moving submarine which may move horizontally and also vertically up to the top of the ocean. The aliens are gathered in a regular formation above the water line from which they drop bombs, or swoop at you kamikaze-like.

You start the game with three lives, which may be lost by being hit by incoming aliens or their depth charges. Points may be scored for each alien killed, with extra points scored if the aliens are caught mid-swoop. Throughout the attack, the water level is continually dropping. This eventually limits the manoeuvrability of your sub until you are constrained to move only horizontally along the bottom of the screen. This continues until the last alien of the wave is killed, after which the water level returns to normal and a new wave of aliens arrives.
