You are the maintenance man just arrived from Earth. Your task is to repair the leaking air pipes in caverns under the Moon's surface, which supply the scientists of COLONY 11, a research station. The inhabitants of these underground caverns are indestructible, so must be avoided.

To help you avoid them you are wearing a jet-pack, enabling you to fly over them, but watch your fuel supply. Press the RETURN key to take off and again to land. You can't use the jet-pack on the surface.

To repair the pipes, you are carrying a plasma laser which when fired underneath the pipe engulfs the leak and seals it. This also drains your fuel supply so use with care.

If you leave a screen without repairing all the leaks, on returning to that screen all the leaks will appear again!

The air tanks on the Moon's surface can be used to replenish your air supply, by plugging in to them. Your air indicator will show how much air you have. Caution - Do Not Overfill!

The game ends if you run out of air, fuel or lives. With every screen you complete an extra life is gained. You lose a life if you come into contact with any inhabitant, so be warned.

On certain screens there are transport pads. You stand on the pad and press SPACE and you will then be transported to the transporter directly above or below you.

When the pressure indicator is full then that round is completed. A bonus will be added to your score; the next round then increases speed making it harder to complete. Good luck!
