The Exit 8
A walking simulator about spotting anomalies in a looping metro passageway.
Last updated
The Exit 8, often called just Exit 8, is a 2023 indie adventure game from Kotake Create (often stylized as KOTAKE CREATE), the solo developer also known as Kotake Create. It is a walking simulator where the player moves through a Japanese metro station corridor, searching for layout errors called anomalies in order to find the station’s exit. The game first came out on Steam on 29 November 2023, then was ported to Nintendo Switch, PlayStation 4, and PlayStation 5 in 2024, and to Xbox Series X/S, iOS, Android, and Nintendo Switch 2 in 2025, all published by Japanese indie publisher Playism. A virtual reality version, The Exit 8 VR, was co-developed and published by MyDearest Inc., releasing on 11 July 2024 for Meta Quest 2, Pro, and 3, and later on Steam and Quest 3S.
Development
Development took nine months, driven by Kotake’s desire to finish a game quickly and cheaply while another project, Strange Shadows, dragged on. The idea came from the surreal feel of underground walkways and liminal spaces; the Finnish horror series I’m on Observation Duty inspired the anomaly-spotting mechanic. The setting was based on real Japanese metro stations, including one in Osaka and Kiyosumi-shirakawa Station in Kōtō, Tokyo.
The Exit 8 earned positive reviews, with critics praising its psychological horror and realistic setting, though some noted its short length and low replay value. The VR version was also well received. It won awards at the Japan Game Awards and CEDEC Awards, and has been downloaded over 2 million times. Its success led to many similar games, called “Exit 8-likes.” A sequel, Platform 8, came out on 31 May 2024.
The Exit 8 is a first-person 3D walking simulator with puzzle and psychological horror elements. Set in a Japanese metro corridor, it draws on liminal spaces like the Backrooms. At the start, a sign shows the rules, and the player begins at Exit 0.
Gameplay
Each time the player leaves the corridor, it repeats endlessly, with a passer-by also stuck in the loop. The core mechanic works like a spot-the-difference game: the player must check for anomalies in the room. If none are found, they continue forward; if one is spotted, they turn back to advance to the next exit. This must be done correctly eight times in a row to reach Exit 8 and leave.
Lore & Background
The Exit 8 was developed over nine months by solo Japanese developer Kotake Create, who had previously worked as a 3D artist at a Japanese game developer. Kotake created the game to release a title on Steam, to work on a shorter project after another game (Strange Shadows) had a long development cycle, and to generate income for living expenses and further development. The game was inspired by the surreal atmosphere of underground passageways and the concept of liminal spaces, with the Finnish horror game series I'm on Observation Duty providing key inspiration for the anomaly-spotting mechanic. The setting was modelled after real Japanese metro stations, including one in Osaka and Kiyosumi-shirakawa Station in Kōtō, Tokyo.
Reader's Guide
The Exit 8 is significant as a low-budget indie title that achieved widespread commercial and critical success, accumulating over 2 million downloads and winning awards at the Japan Game Awards and CEDEC Awards. Its gameplay—a first-person loop through a corridor where players must identify anomalies to progress—spawned a subgenre of imitators called 'Exit 8-likes'.
The game's success led to ports across numerous platforms, a virtual reality version co-developed by MyDearest Inc., and a live-action film adaptation released in Japan in August 2025 and in the United States in April 2026. A sequel, Platform 8, was released on 31 May 2024. The game's legacy lies in demonstrating how a simple, focused concept—spot-the-difference in a horror setting—could be executed effectively with limited resources and resonate with a global audience.
