Valis IV[a] is a 1991 action-platform video game originally developed by Laser Soft and published by Telenet Japan for the PC Engine CD-ROM².

The dark world prince Galgear, who lost self-control after acquiring a magical ring, broke from his fifteen-year imprisonment by the gods of Vecanti, kidnapping Valna and being pursued by troops led by Cham.

Lena, a member of Cham's band, is joined by her sister Amu and the prince's father Asfal on a journey to retrieve the titular sword and defeat Galgear.

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

This ring increases his powers, but to the loss of control he could have maintained under its effects, and the gods of Vecanti recognize this and imprison Galgear inside a crystal sunk into the ocean.

[8] The title was included as part of the Valis: The Fantasm Soldier Complete compilation for Microsoft Windows, published by Sunsoft in 2004 under a limited run of 2000 copies, which came bundled with a bonus CD and a figure.

[21] Likewise, Joystick's Jean-Marc Demoly and Joypad's Alain Huyghues-Lacour commended the game for its graphics, animations, music and controls, but noted the prolonged loading times.

Nevertheless, while Mike regarded it as a good addition to the Valis series, both Ken and Samrye commented that it "loses a little in the plot dimension" and felt similar to previous entries.

Consoles +' François Hermellin and Kaneda Kun commended the game's graphical presentation of most stages and classic-style playability, finding it "neither excessively difficult nor particularly innovative."

[29] Joypad's Alain Huyghues-Lacour and Olivier Prézeau echoed similar thoughts as Demoly, but both noted that the title was structurally different compared to the PC Engine CD-ROM version.

[27] Mega Fun's Philipp Noak and Bastian Lorz faulted its simplistic visuals, low number of enemies on-screen, and audio but noted its animations in a positive light.

[30] Super Pro's David Westley highlighted the game's colorful and imaginative backgrounds, high quality cutscenes and adequate audio, but panned its bosses for their slow animations and monotonous gameplay.

[35] Video Games' Julian Eggebrecht labeled its visuals and audio as "catastrophic" for Super Nintendo standards, and criticized its level design and uninteresting enemies.

"[31] Hardcore Gaming 101's Kalata opined that Super Valis IV is "just kind of bland and boring, and very disappointing in comparison to the CD-ROM powered version.
