Valis III[b] is a 1990 action-platform video game originally developed by Laser Soft, published by Telenet Japan and NEC for the TurboGrafx-CD.

King Glames, wielder of the sword Leethus, leads denizens of the dark world to conquer both Vecanti and Earth, seeking refuge for his people amid the destruction of their planet.

Valis III was created by most of the same staff members who worked on the previous entry at Laser Soft, an internal gaming division of Telenet.

[1][2] Together with her two allies, Valna and Cham, Yuko must prevent the Dark World's king, Glames, who is wielding the sword Leethus, from destroying Vecanti and Earth, .

Each character uses different upgradable weapons (Yuko has a chargeable energy wave, Cham has a whip, and Valna shoots magical blasts from her wand) and spells (of lightning, fire, and ice variety).

[3] King Glames[c] leads denizens of the Dark World to conquer both Vecanti and Earth, seeking a home for his people before the destruction of his planet.

[4][5] Later, they visit the ruler of Vecanti, Nizetti,[d] and unleashes the Valis blade's full potential, which culminates in a climactic battle between the three girls and Glames as well the returning antagonist from the first game, Rogles.

The Valis sword retires to the heavens, and Vecanti prepares itself for prosperity, while Cham and Valna wave goodbye to Yuko as she departs to take on her new role.

[9][10] 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.

[9][13] The game was shown off at the 1991 Summer Consumer Electronics Show and originally slated for a January 1992 launch in North America,[14][15] before being eventually published by NEC in March 1992 for the TurboGrafx-CD.

[19] 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.

[20][21] 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.

[26] 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.

[1] Aktueller Software Markt's Sandra Alter also commended the graphics, sound and gameplay, but criticized its animated cutscenes between stages for their length.

"[3] The Sega Genesis version of Valis III carried similar reception as the original TurboGrafx-CD release,[2] most of which also reviewed it as an import title.

Readers of the Japanese Sega Saturn Magazine voted to give the title a 6.029 out of 10 score, ranking among Mega Drive games at the number 396 spot in a 1995 public poll.
