STUDIO909 released a Steam demo for the mystery adventure game Quiet Express Room 909 on October 17, 2026. The game is set on the Quiet Express, a train that crosses the continent over seven days. Players wake in the rear-most passenger car and move toward the front while searching for Room 909, a cabin that should not exist. At each door, three car candidates are drawn by lottery from passenger cars, dining cars, botanical gardens, and freight cars, and the player chooses which to connect. Exploring yields items that reroll the candidates or add a fourth option, and rearranging the train's composition opens new passages. On day seven, just before the final station, the Quiet Express derails and everyone aboard dies, sending the player back seven days to repeat the journey. The demo runs about 30 minutes and offers multiple ways to avert the derailment. Quiet Express Room 909 is scheduled for release in 2027. The price is undecided.
Direction and scenario are handled by indie developer Kazuhide Oka, whose earlier credits include Natsuno Kanata and Girls Made Pudding. STUDIO909 has twice been selected in the Ministry of Economy, Trade and Industry creator support program Soufuu, in its second and third rounds.
The design draws on two reference points the studio has named: the puzzle adventure Blue Prince and the road trip adventure Road 96. The train crosses toward the western coast of the continent, and the passengers who board at each station include beastfolk, giants, and homunculi living in a world where the era of long conflict and discrimination has ended. Each carries private worries, whether the hardships of living as their race or regrets from the past, and repeated conversations and completed requests feed into the mystery of Room 909.
The demo sits alongside a new trailer and an official Discord server opened for strategy information and updates. The showcase announcement was carried by The MIX Fall Showcase 2026.
