Super Turrican

The lost colony of Alterra is a completely man-made lifeworld abandoned long ago in a nearby galaxy. Alterra is actually five colonies in one. Each self-contained habitat has been separately bio-engineered by a powerful ecosystem generation network known as a Multiple Organism Unit Link. MORGUL, for short.

Early colonists used MORGUL to render Alterra inhabitable. But a cataclysmic quake severed all system interface functions, and MORGUL murderously rebelled. The few colonists lucky enough to escape told a grim tale of a higher intelligence gone berserk.
