Shin Megami Tensei III: Nocturne HD Remaster

A remastered edition, titled Shin Megami Tensei III: Nocturne HD Remaster, was announced during Nintendo Direct Mini: Partners Showcase on July 20, 2020 alongside the release year for Shin Megami Tensei V. It is based on the Maniax Chronicle Edition release, and includes voice-acted cutscenes and additional difficulty settings. Production of the remaster began in 2018 and lasted around two years. The new "Merciful" difficulty setting was included as a concession to modern gaming trends, acknowledging players who would want to easily experience the stories and endings. Alongside these and graphical changes, some dialogue was rewritten. A "Maniax Pack" downloadable content item launched alongside the game, restoring Dante in place of Raidou Kuzunoha. The original television commercial was remade around the production's theme of "respect for the original", with original staff returning to create both a 15 second television version, and a web-exclusive 30 second version.

The remaster was released in Japanese, Traditional Chinese and Korean on October 29, 2020 for the Nintendo Switch and PlayStation 4, with a worldwide release and Microsoft Windows version planned for May 25, 2021. For the Asian release published by Sega, the Chronicles content was originally omitted. Later, Sega and Atlus offered the content as DLC for Chinese players. Due to protests from Chinese consumers, the Chronicles content was offered as DLC exclusively for Chinese players. It was free for a two week period before becoming a paid item on January 7 of the following year.
