Planet Earth faces grave danger from the attacking hordes of the evil mutant empire! Already, they have conquered the United Federation's Moonbase HQ. Their technology has proved too powerful for Earth's primitive defences. Only Project-X can hope to save the planet!
Using ancient alien technology, Project-X has created the ultimate fusion of man and machine: the bio-melded human and spaceship they call…… IXION !!!
With your nervous system directly linked to the spaceship controls, you must use your bio-enhanced speed and dexterity to force back the invading evil.

Your mission is in three stages:
1. Repel the mutant army from the Earth
2. Retake the lunar base to ensure the Earth's short term security
3. Root out this evil at it's source! Find the alien homeworld and destroy the fiendish mastermind behind this dastardly invasion!
