The Mechanoid Invasion (and its source books, supplements and sequels) was the first role-playing game from Palladium Books, conceived and written by Kevin Siembieda, with contributions from Erick Wujcik.[1]


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,[2] the game was published as a series of three comic-book sized sourcebooks:[3]

  1. the first, The Mechanoid Invasion, dealt with the eponymous invasion of Gideon E
  2. the second, Journey, dealt with human survivors living within a mechanoid mothership after the destruction of the Gideon E colony and introduced "minor magic and some psionics",[4]
  3. the third, Homeworld, dealt with the Mechanoid homeworld itself.


The first book was revised and republished in an expanded form in 1985.[5]

In Spring 1991 Caliber Comics also produced a 3-book series called The Mechanoids which adapted the RPG into comic book stories.[6]

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.[7]

In Winter 1998 a Collected Mechanoids RPG was released.[8] By 2001 all 3 books were compiled as the Mechanoid Invasion Trilogy[9] which is still available.[10]

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.[8] As of 2018, it is still available in the store labelled "coming soon".[11]


William A. Barton reviewed The Mechanoid Invasion in The Space Gamer No. 42.[12] 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."[12]
