Play Portopia Renzoku Satsujin Jiken (Japan) Online

Portopia Renzoku Satsujin Jiken came out for the Nintendo Entertainment System in 1983, developed by Yuji Horii. It was an early title for the console, a time when many games were still figuring out what the medium could do beyond pure action. This one stood apart by trying to tell a complex, adult story within the technical limits of the hardware.

You control a detective from a first-person perspective, investigating a murder by moving screen by screen through locations like a harbor and a mansion. The main objective is to solve the case by exhaustively questioning witnesses, gathering evidence from the environment, and making deductions from your notes. Signature mechanics include a verb-based command menu where you type short words like "look" or "talk" to interact with the world, and a telephone you use to call contacts for information. The pacing is slow and deliberate, often difficult due to obscure logic that expects you to try everything. It feels like doing real, sometimes frustrating police work inside a computer.
