Publisher G-Mode announced on 23 October 2026 that Zoku Portopia Renzoku Satsujin Jiken: Boukyaku no Maisou (続ポートピア連続殺人事件:忘却の埋葬, roughly “Portopia Serial Murder Case Continued: Burial of Oblivion”) will launch on 4 March 2027 for Nintendo Switch, Nintendo Switch 2 and Steam. The game remakes the 1983 detective adventure that started Yuji Horii’s career. Pre-orders for the Switch and Switch 2 packages opened the same day, according to G-Mode’s press release on PR TIMES.
Five new investigation files
G-Mode describes the game as a full remake of The Portopia Serial Murder Case with a large amount of new story, which makes it a new game rather than a straight port. It adds five new investigation files. The new package art, by WIT STUDIO’s Kyoji Asano, puts the original’s Yasu and Fumie against Kobe’s night skyline, surrounded by characters from the new files.
Horii, who created the original and went on to make Dragon Quest, is credited as original creator and general production director. Pianist Shinya Kiyozuka writes the music. ORION PROJECT handles planning and production, room6 and Game Studio develop, and G-Mode publishes. The game was first revealed in the Nintendo Direct of 9 September 2026 with only a 2027 window, as G-Mode’s September announcement noted.
The Famicom original on the cartridge
The physical Switch and Switch 2 editions, both standard and limited, carry the complete Famicom version of Portopia as a bonus, so players can compare the 8-bit original with the remake on one console. The download and Steam versions do not include it. Prices in Japan, tax included:
- Switch / Switch 2 download and Steam: 4,800 yen
- Switch / Switch 2 standard package: 7,678 yen
- Switch / Switch 2 limited package: 9,878 yen, adding an A5 booklet and an original soundtrack CD
An official-store deluxe edition, including a version with a Steam code, will be detailed later. The press release lists Japanese as the only supported language, and the CERO rating is still pending. G-Mode has not announced an English release.
A remake of a twist everyone knows
The 1983 Portopia is one of the founding texts of the Japanese adventure game, and its most famous reveal is still a cultural joke in Japan four decades later. A remake has to decide what to do with a twist most of its audience already knows. The five new files, which the September announcement says are told “from a changed perspective” and supervised by Horii, look like the answer: keep the original intact, and put the surprises somewhere new.
The sequel also contrasts with Horii’s other Portopia-adjacent project this month: a small browser interrogation game that he said he made with generative AI in about 30 minutes (our earlier report). Zoku Portopia is a conventional, studio-built production with a composer, a character designer and a physical limited edition.
