is a space combat and trading video game designed by Andrew Glaister and published by Firebird Software in 1986 for the Commodore 64,[1] ZX Spectrum, and Amstrad CPC.

Each system has a starbase – which issues missions, receives supplies from the player, and sells various ship add-ons – a sun that presents a navigation hazard due to its high temperature, and one or more orbiting planets.

The three supplies – people, minerals and radioactives – are then made available for pick-up in the main playing area and can be transferred back to the starbase.

Eventually, the player is able to create a vaccine to combat a plague, which destroys systems 200 stardays from infection.

The last task of the game is to deploy a defence shield network to secure the player's empire from invaders.
