RAYBIS GAMES announced Mandatory Overtime on November 9, 2026, and opened the game's Steam store page the same day, according to news.denfaminicogamer.jp. The first-person psychological horror title is planned for PC via Steam, with no release date set.
Players take the role of a new employee on their first day at a small advertising and printing company in Japan. The job is handled through an in-office PC, with tasks including sales tallying in spreadsheet software, ad corrections, writing emails and printing documents.
On that first day the boss orders overtime, leaving the player alone in the office late at night. Strange events follow, among them noises from an empty meeting room, a ringing phone and suspicious messages on the PC.
Mandatory Overtime is developed by TADAIMA WORKS and sold by RAYBIS GAMES. The setting is a Japanese "black company", the term used for employers with demanding working conditions.
