Concept.
"The Mechanoid Invasion" centered on a powerful, malevolent, and numerous race of bio-driven machines that had come to invade a planet called Gideon E that was colonized by humans. In its original edition, published in 1981, the game was published as a series of three comic-book sized sourcebooks:
Legacy.
The first book was revised and republished in an expanded form in 1985 as "The Mechanoids".
In Spring 1991 Caliber Comics also produced a 3-book series called "The Mechanoids" which adapted the RPG into comic book stories.
In the early 90s "Sourcebook Two" of "Rifts" was released, titled "The Mechanoids", and it included MDC conversions for the Mechanoids for use in a Rifts Earth setting, along with a storyline on how they got there.
In Winter 1998 a Collected "Mechanoids RPG" was released, compiled as the "Mechanoid Invasion Trilogy" which is still available.
"Mechanoids Space", a complete RPG first announced in 1993 for release the following year, was last promised for publication in December 2002 as late as September 2002. it is still available in the store labelled "coming soon".
Reception.
William A. Barton reviewed "The Mechanoid Invasion" in "The Space Gamer" No. 42. Barton commented that "If you can overlook its amateurish production (and the price helps in this), I think you'll find "The Mechanoid Invasion" worth the investment. It should provide some enjoyable role playing in an SF setting as a break from "Traveller" or your other favorite SF RPG."
