The Starion Cluster is under threat from the Pioneer Plague, which is
spreading to every planet and destroying its lifeforms, having over-riden its
original programming to merely transform uninhabitible planets into lush
verdant lands for human colonization. The only solution is to fly to each of
these planets and shoot out the pods from which the Plague hatches.
The gameplay essentially has 3 different sections. The main shooting action
involves taking out as many of the pods as possible, while avoiding being shot
by the Plague’s self-generating protection robots. The more pods you destroy
on each level, the easier the next levels will be.
Before each level you must fly to it through a mouse-controlled 3D section –
completing the task quickly will again make your task easier. One unique
feature is the ability to program the attack paths that your ship’s two probes
will follow when deployed – this is done by moving the joystick in the
appropriate set of directions, producing five options which can be activated
