Everyone knows about ‘Space Invaders,’ but do you know their side of the story? Play it from the alien’s perspective: You command a fleet of Space Defenders, whose responsibility it is to bring peace to the galaxy. Your swarm of stealth spacecraft have tracked the enemy force back to their home planet. This enemy is a brutal and heartless one, set on invading other civilisations, enslaving populations, and using the rich natural resources of your lands – having almost entirely ruined their own. Your mission is to bring peace to the galaxy by destroying every last one of them.
