Mystery ADV Quiet Express Room 909 Repeating a 7-Day Train Journey Set for 2027 Release
Studio 909 announced on June 3, 2026, that the mystery adventure game Quiet Express Room 909 will launch on Steam in 2027. The announcement was made during the Best Indie Games Summer Showcase 2026, alongside a new key visual and trailer. Directed by Kazuhide Oka, known for Girls Maid Pudding and Natsu no Kanata, the game places players in a train crossing a continent over a week. The train crashes on the seventh day, and time rewinds to the first day, creating a loop structure. Players explore the train from the rear car toward the front, searching for Room 909, a compartment that should not exist. The world includes beastmen, giants, and homunculi among the passengers. Players interact with passengers, complete requests, and choose which of three randomly selected cars to enter next. Rearranging cars may open hidden passages. The game is influenced by classic adventure titles such as Blue Prince and Road 96.
