In a move that surprised fans, a sequel to the legendary Japanese adventure game, The Portopia Serial Murder Case, was revealed during this week’s Japanese Nintendo Direct. Notably, this announcement was exclusive to the Japanese showcase, with the new follow-up absent from Western presentations. This sequel connects directly to the formative 1983 title created by Yuji Horii—the mastermind behind Dragon Quest—and is widely credited with shaping Japan’s early text-based mystery gaming landscape.
Celebrating over four decades of mystery-solving
The Portopia Serial Murder Case originally arrived 43 years back, debuting on Japanese PCs before later launching on the NES. Its gripping murder-mystery gameplay propelled Enix, which has since merged with Square Enix, to considerable success. This game’s legacy continues to influence Japanese developers; for instance, Hideo Kojima has repeatedly mentioned in interviews that the title inspired his own development journey.
The most recent Japanese Nintendo Direct, which also included news on titles like Kirby and the World Beyond, Metroid Ravenous, and a brand new The Legend of Zelda: Ocarina of Time, showcased the first footage of the next Portopia, now carrying the subtitle “The Portopia Serial Murder Case: Burial of Oblivion”. The video preview revealed not only a continuation of classic text-based investigations and dialogue-driven gameplay, but also a fresh narrative anchored by new serial killings.
Yuji Horii leads the charge, with global fans awaiting more details
The title’s Steam page states that Yuji Horii is guiding the project as executive director. There is, however, no official word regarding English-language options for the international market. According to current plans, the new installment will debut in 2027 for both PC and the upcoming Switch 2 console.
The Steam listing hints at a fully original detective plot, set this time in 1980s Kobe. Players will step into the shoes of a new cast of investigators, called to crack another series of connected murders echoing events from the first game. Staying true to its heritage, the sequel brings back the menu-driven, text-command gameplay, with detectives piecing together the truth from both witness testimony and physical evidence.
Square Enix’s hands-off approach and Portopia’s enduring influence
Although Enix—now Square Enix—released the original, the company appears to have no role in producing the forthcoming sequel. In contrast, three years ago Square Enix did revisit the franchise through an “educational demonstration” that leveraged Natural Language Processing (NLP) technology. This AI-driven experiment was poorly received, earning a ‘Very Negative’ rating on Steam and failing to win over fans of the beloved classic.
With Yuji Horii engaged directly in the project, anticipation is especially high among longtime players in Japan. As the 2027 launch nears, fans around the world are eager for news about an international edition and additional language support to introduce this iconic mystery to a new audience.
