(ca. 1990) - campaign book. A very Gundam-esque adventure in which representatives of both major political factions on Algol are sent on a long-range interplanetary mission to determine the nature of an anomaly at the edge of the star system. Written to be played as 'episodes' in a 'series'. (Reference was made in this book and the later Mekton Empire that the anomaly was in actuality a nonfunctional stargate such as is used in the Bendarian Empire.) Mekton Techbook/Mekton Technical System (MTB/MTS) (1991) - a major conversion of the mecha-building system of Mekton Mekton Empire - This expansion book reduced the Algol system to just one more star among hundreds in the Bendarian Galactic Empire. Mekton Zeta (メクトン Z) (1994) - general update and improvement of Mekton II Mekton Zeta Plus (メクトン Z プラス) (1994) - general update and improvement of the Mekton Techbook Gundam Senki (2000) - Japanese language Mobile Suit Gundam RPG using the Mekton system. Scheduled for US release, release date unspecified at this time. Mekton Zero (TBA) - crowdfunded project, on indefinite hiatus after being delayed for five years. Official settings Algol - A "grab bag" setting in an alternate universe, mixing many different styles of anime together. This setting originated with the first edition of Mekton, and was continued in the well-received expansion book Operation: Rimfire. Algol was the default setting for Mekton and Mekton II (as well as Operation: Rimfire and Landstriker), and remains in Mekton Z for legacy purposes (as well as getting a passing reference in Mekton Empire). Algol is a long-lost human colony of the Bendar Galactic Empire, where the various factions are locked in a cold war and must deal with an impending ice age and the possible return of their ancient alien enemy, the fearsome Aggendi lizard warriors. The Algol Mailing List continued development on Algol into the early 2000s. Mekton Empire - A space opera setting taking hints from Captain Harlock, Gundam and Voltron, set in the distant Bendar Spiral Galaxy. It added rules for playing aliens (including non-humanoids), space combat, psionics and creating new alien creatures. Jovian Chronicles - A heavily Gundam-inspired licensed setting created by Dream Pod 9, set in the 23rd Century. This would later become a separate game using Dream Pod 9's Silhouette System. Invasion Terra - A Macross-like setting in the future of 2105. Imperial Star - Very similar to Mekton Empire but
