Valis III was developed by
Laser Soft, an internal gaming division of Telenet, previously responsible for
Valis II (1989). It was created by most of the same staff members who worked on the previous entry, with both Masami Hanari and Fumiyuki Moriyama reprising their roles as director and producer respectively, while animator Osamu Nabeshima returned as one of the game's artists. Because of being released on CD-ROM, the team was able to include animated cutscenes into the game as they had done before with
Valis II.
Valis III was first released for the
PC Engine CD-ROM² (the Japanese iteration of the
TurboGrafx-CD) by Telenet on September 7, 1990. before being eventually published by
NEC in March 1992 for the TurboGrafx-CD. The game was then ported to the
Sega Genesis, published by
Renovation Game (Reno) in Japan on March 22, 1991. Telenet also released the Genesis version through its subsidiary
Renovation Products in North America in June 1991. A European release was planned by
UbiSoft, as part of a multi-game licensing deal with Renovation, but it was never officially released in the region for unknown reasons. The Genesis conversion was co-programmed by Yoshiki "UAI" Yamauchi and Masayasu Yamamoto, who had prior involvement with the
series since
Valis: The Fantasm Soldier.
Michiko Naruke, best known for her work on the
Wild Arms series, was involved in the Genesis adaptation as one of three composers under late sound director Shinobu Ogawa. A new stage was introduced for the port, but most of the cutscenes and multiple stages were removed due to cartridge size limitations.
Valis III was included as part of the
Valis: The Fantasm Soldier Complete compilation for
Microsoft Windows, published by
Bothtec in 2004 under a limited run of 2000 copies, which came bundled with a bonus CD and a figure. In 2011, D4 Enterprise re-released the compilation again with
SD Valis and
Super Valis as
Valis: The Fantasm Soldier Complete Plus, which came bundled with a CD soundtrack instead. The PC Engine version was included in the
Valis: The Fantasm Soldier Collection compilation for the
Nintendo Switch in Japan by Edia on December 9, 2021. The physical edition of the collection is also planned for a western release by Limited Run Games. It was re-released separately through the
Nintendo eShop by Edia first in Japan on February 10, 2022, and later in Europe and North America in March 2022. The Genesis port was included as part of the
Renovation Collection 1 compilation for
Evercade, launched in 2022 by Blaze Entertainment. In 2023, the Genesis version was included as part of
Valis: The Fantasm Soldier Collection III for Switch. == Reception ==
