From publisher blurb:
Your WarStar has been sent to invite the Colonial Planet of Corenth to the Quortium. They have diplomatically declined. You and your crew must see them safely home, but a hidden threat has stowed upon the WarStar "Unicorn". And it will threaten the peace and safety of everyone on board, and the planet too.
So slap on your helmet, radio HQ, hit "Turbo", and blast off for a couple hours of adventure!
