From the inlay:
As the space forces chief mug, oops sorry I mean hero, it has fallen to you to undertake the incredibly dangerous and difficult, no sorry I meant trivial and safe, mission to reclaim the Dynatron Cores from the strongly defended and booby-trapped, whoops at it again I really meant deserted, alien bases.
Guide the space commando through the alien complex to find and reclaim the eight Dynatron reactor cores. Then escape before the automatic defence system blows you up. While avoiding all the aliens that are out to kill you, what could be simpler. I mean nothing could go wrong, now could it...
and all the other hazards of a spaceman's life.
