Valis IV was developed by
Laser Soft, an internal gaming division of Telenet, previously responsible for
Valis III (1990). It was created by most of the same staff members who worked on previous entries in the
Valis series, with both Mitsuo Nakamura and Masami Hanari being director and producer respectively. Haruyuki Nishida, who was also responsible as designer with assistance from Chiyo Rara, co-wrote the scenario along with Bunzō Matsui. 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. The original PC Engine CD version was re-released in digital form for Windows through
D4 Enterprise's Project EGG service on August 21, 2007. In 2011, D4 Enterprise re-released the compilation with additional titles as
Valis: The Fantasm Soldier Complete Plus, which came bundled with a CD soundtrack instead.
Super Valis IV A vastly different version for the
Super Nintendo Entertainment System, titled
Super Valis IV (known in Japan as
Super Valis), was first published in Japan by Telenet on March 27, 1992, and later in North America by
Atlus Software in February 1993. In December 2020, it was added to the
Nintendo Classics service. In 2023,
Super Valis IV was included as part of
Valis: The Fantasm Soldier Collection III for Switch. Hal Nishida was responsible for rearranging the game under direction of Masami Hanari. Extensive changes were made to
Valis IV when it was adapted to the Super NES: Two of the three playable characters from the original (Amu and Asfal) were replaced with Yuko (which could be played via a cheat code), the magic system was replaced by special items and weapons, and the animated sequences from the original version also were removed. Though several levels were removed, a new level was designed for this version. == Reception ==
