Copenhagen, Denmark – September 1, 2026 – Independent developer Half Past Yellow has officially announced that their upcoming co-op horror game, Stream Train, will launch on Steam on October 15, 2026. In addition to the release date announcement, players can now register for an upcoming playtest directly on the game's official Steam page.

Stream Train challenges up to six players to squad up, customize their avatars, and take control of an old steam train to explore the cryptid-infested wilderness of the Uncanny Valley. In this unique survival horror experience, players attempt to go viral by livestreaming their rail journey through an abandoned railroad, investigating derelict buildings, and documenting strange creatures.

Survival depends on more than just outrunning the supernatural. Players must keep their audience engaged by capturing content and pulling off pranks, as chatters react in real-time to everything they see. By keeping the content flowing, chatters will keep donations and support rolling in - which are vital for making it through alive. From ghosts and cryptids to angry forest entities, players will face terrors where the golden rule is simple: try not to make them angry, or at least film it when you do.

"The team have poured their heart and soul into Stream Train and we are excited to get the game in front of players." said Remy Stuurwold, CEO. "I have always wanted to build a game with livestreaming as a mechanic, pairing it with the social co-op/friendslop genre made complete sense. I can't wait to see what players think of Stream Train." adds Max Wrighton, Game Director.

Key Features:

• Keep Chat Happy: Engage a dynamic livestream chat that reacts to your experiences, issues challenges, makes requests, and rewards your entertainment with crucial donations and support.
• All Aboard!: Up to 6 players can squad up, customize their avatars, and explore the Uncanny Valley at their own pace aboard an old steam train in pursuit of internet virality.
• Don't Die: Navigate a forest crawling with cryptids, ghosts, and strange creatures. Keep your camera rolling—even when things go horribly wrong.
