Your mission is to rescue the stranded scientists from the surface of the planet Mercury. After leaving the mothership, you have to steer very carefully through an asteroid belt to land on one of the three pads. One of the scientists hops on board and you attempt to return to the mothership which is bouncing overhead from one side of the screen to the other.

The joystick fire button operates the release from the mothership and also your rate of descent/ascent. The game is uncomplicated, but at least the graphics are crisp and smooth with interesting colour. Well presented for family entertainment.
