Each race has a mission that is special to it. The mission which corresponds to your "mission 9" is specified with the PlayerSpecialMission parameter. By default, that parameter is identical to PlayerRace, which in turn is equal to your player number by default. This defines eleven standard races with special abilities and each with their own special mission.

This is a testing version.
It may be incomplete, and have more bugs (or features) than the public live version at planetscentral.com.
