Summarized from pages 20-21: After thousands of years of warfare, the Mechanoids have inexplicably...died. Across six galaxies, in the span of 53 seconds, every Mechanoid everywhere has died without warning or explanation. Except for one world: the Mechanoid Homeworld. Is the Mechanoid threat over? Or is there truth to the rumor of a Mechanoid Apocalypse Machine? This is the setting for Homeworld, the third book of The Mechanoid Invasion trilogy. Homeworld contained complete rules of play and added additional player classes, races, more complete psionic rules, and descriptions of the defenses of the Mechanoid Homeworld.
