Sigma Harmonics[a] is a 2008 role-playing video game co-developed by Square Enix and Think Garage, and published by Square Enix for the Nintendo DS. An expanded port for mobile devices was released in 2010 under the title Sigma Harmonics Coda.[b] The storyline follows Sigma Kurogami, a member of a magical family based in Tokyo. He goes on a mission through time with childhood friend Neon Tsukiyumi after demons escape the family's imprisonment and rewrite history through a series of murders. The gameplay combines role-playing combat mechanics, and adventure-style investigation and storytelling.
Production began following the release of Dirge of Cerberus: Final Fantasy VII in 2006; that game's writer Hiroki Chiba acted as both director and writer for Sigma Harmonics. Other returning team members included producer Yoshinori Kitase, artist Yusaku Nakaaki, and composer Masashi Hamauzu. The premise was inspired by Chiba's liking for Shōwa period mystery writers. The team used tools supplied by CRI Middleware to both fit all their planned content on the DS cartridge and incorporate Hamauzu's music with minimal reduction in quality.
First announced in March 2008, it was promoted using an episodic radio drama released through the game's website, and a series of commercials blending gameplay footage with anime sequences created by Sanzigen. The mobile port included a section designed as a standalone demo for the original. No version of the game has left Japan, a fact attributed to its extensive incorporation of Japanese culture. At release, it was one of Square Enix's more successful original titles, selling 70,000 units within a month. Reception of the game in Japan and its limited Western reviews has been generally positive, with praise going to its battle system and investigation mechanics.
