Game Spark Plays Portopia Serial Murder Case Continued Demo at Tokyo Game Show 2026
The demo is an early look at how a 1980s detective adventure is being rebuilt with modern controls and a 3D dungeon, and whether that makes it readable for players who only know the phrase "the culprit is so-and-so."

At Tokyo Game Show 2026, held at Makuhari Messe from September 17 to 20, Game Spark played a demo of The Portopia Serial Murder Case Continued: Burial of Oblivion, a G-MODE title shown during the September 9 Nintendo Direct presentation. The demo follows a suicide case, lets the player question Yasuhiko Mano, and descends into a 3D basement dungeon. G-MODE's Koichi Takeshita discussed the project.
The playable demo opens on the case of Kozo Yamakawa, president of Loan Yamakin, who has committed suicide, and sends the player to the Yamakawa residence to gather evidence. Options appear from the first scene, including arresting Yasuhiko Mano, and picking wrong ones draws mockery or a calm retort from Yasu. Message display speed can be changed, and Game Spark found the controls quick with no stress on the system side.
Evidence must be collected after it is found, a retro habit Game Spark forgot several times. A suspicious basement leads to a 3D dungeon and a locked door that ended the demo timer.
