TLDR

LEVEL-5 has released roughly 45 minutes of DECAPOLICE footage covering both paths from its Tokyo Game Show 2026 demo: City Patrol and Case Quest. The show-floor build let players either roam the city or work through a case, though LEVEL-5 listed Japanese as its supported language. The footage offers a longer look at the crime RPG’s investigation-to-battle loop before its planned 2027 launch on PlayStation 5, Nintendo Switch 2 and PC via Steam.

LEVEL-5 has released a full playthrough of DECAPOLICE’s Tokyo Game Show 2026 demo, turning a short show-floor slice into about 45 minutes of footage for players who were not in Chiba. The two-video package published by Gematsu follows both choices offered by the demo: City Patrol and Case Quest.

The split matters because DECAPOLICE is built around more than one kind of detective work. LEVEL-5’s official TGS page told attendees they could either solve a case or patrol the city. The show-floor build supported Japanese, so the new footage is a visual tour rather than an English-language walkthrough.

From crime scene to confrontation

City Patrol shows the freer side of the demo, while Case Quest puts its investigative systems in focus. In a September presentation reported by Gematsu, LEVEL-5 CEO Akihiro Hino described “Decaism” as a process of examining crime scenes recreated in a virtual world, gathering evidence and questioning people connected to a case.

Players then arrange what they have learned on a Case Board and use those findings to identify a culprit. The loop does not stop at deduction: Hino said investigation, arrest and battle are designed to flow into one another. Optional Case Missions add more mysteries outside the main path.

LEVEL-5 also worked with SCRAP, the company behind real escape games and other immersive experiences, on case concepts. Hino identified the Three Mafioso Murders as one scenario adapted from a SCRAP concept, giving the game’s puzzle structure a connection to real-world escape-room design.

A longer wait after the demo

The footage arrives after a Tokyo Game Show disrupted by severe weather. Gematsu reports that the event ran September 17–20 at Makuhari Messe and lost a planned fifth day. DECAPOLICE was one of four playable games at LEVEL-5’s booth.

DECAPOLICE is now scheduled for 2027 on PlayStation 5, Nintendo Switch 2 and PC through Steam. LEVEL-5 has not announced an exact release date, but the extended City Patrol and Case Quest recordings provide the clearest look yet at how its investigation, deduction and combat systems connect.
