Code Age (コード・エイジ, Kōdo Eiji) is a 2005 multimedia franchise developed and published by Square Enix. It was created by Yusuke Naora and split between three projects; the manga Code Age Archives, the mobile role-playing video game Code Age Brawls, and the PlayStation 2 action role-playing game Code Age Commanders. Code Age uses a science fiction setting on the inner surface of a hollow world similar to a Dyson sphere. The narratives revolve around an apocalyptic threat to civilization, with the protagonists gaining powers from absorbing monsters dubbed the Otellos.
The concept for Code Age was created in 2002, being adopted into Square Enix's "polymorphic content" strategy of producing series across multiple platforms and media. The development team behind the project went under the name "Warhead". Naora led production and created the story for the series, Toshiyuki Itahana designed the characters and directed Commanders, and Kumi Tanioka composed the music for Commanders and Brawls. The manga was created by Aya Kyu under Warhead's supervision, with Naora designing the characters.
The manga Archives was serialised Monthly Shōnen Gangan from 2005 to 2006. The console game Commanders was planned for a Western release, but this was cancelled after the translation had been completed. The mobile entry Brawls operated for less than a year before closing down in September 2006. Reception of Commanders and Brawls was generally positive from Western critics, though Commanders met with low sales in Japan. The Code Age project was also noted for its ambitious multimedia approach at the time.
