Startopia Walkthrough:
Mission 9: The Polvakian Aristocracy
This mission actually isn't too bad. The trick is to stay small. Just build up 6 segments - 2 on each level. Don't build a starport - you really don't have room for one and you don't need it. Build the basic items and stay small. The rest of your enemies will fold pretty quickly as they run out of cash!
