The G-MODE Archives+ series is active, with the Namco Chronicle crossover RPG released on May 28, 2026, and Toudou Ryuunosuke Detective Diary Vol. 8 released on June 4, 2026. The series continues to revive feature phone games for modern platforms.
G-MODE Archives+ is a revival project that brings feature phone games to modern platforms. The series launched its second Bandai Namco Entertainment title, G-MODE Archives+ Namco Chronicle, on May 28, 2026 for PC and Nintendo Switch. The tactical RPG originally developed as a feature phone app brings together characters from classic Namco titles including Valkyrie, Gil, Beraboh Man, Mappy, Taira no Kiyomori, and Wagyan. The story is split into three arcs: Fantasy Arc, City Arc, and Space Arc, with adventure segments featuring crossover stories that go beyond the original games. The title costs 800 yen.
On June 4, 2026, G-MODE Archives+ added Toudou Ryuunosuke Detective Diary Vol. 8: The Violet Birdcage ~The Doll Mansion Serial Murder Case~ for Nintendo Switch. The mystery adventure was previously only available on feature phones, making it a rare title in the series that began in 1988. Set in Taisho 14 (1925), the story follows private detective Toudou Ryuunosuke investigating a missing person case at a Western-style mansion. The game is priced at 1,200 yen with a 20% launch discount until August 2. A hint collection is available on the official website. Previous titles Vol.1 through 7 are already available on Nintendo Switch.
G-MODE, the company behind the Archives+ series, also announced on June 18, 2026 that it will handle publishing and development support for One Song, One Life, a rhythm adventure game planned by LOVE ANNEX and developed by C-Route. That game is scheduled for release on PC via Steam in 2026 and is not part of the Archives+ series, but shows G-MODE's broader publishing activity beyond the revival project.
