Stream Train is a co-op horror game for up to six players, set to launch on Steam on October 15, 2026. Closed playtest registration is open, and the game currently supports English only.
Half Past Yellow, a seven-person Danish studio, announced Stream Train in July 2026. The co-op horror game, for up to six players on PC, places players on a steam locomotive traveling through the Uncanny Valley region. They film supernatural creatures and livestream their journey, with viewer donations and chat requests shaping how they handle the horrors they encounter.
The core mechanic forces players to balance safety against the pull of viral content. Viewer counts and donations depend on dangerous stunts and pranks, and real-time chat reactions and viewer requests add pressure. The studio, which has won four awards with titles like Time on Frog Island, began development in September 2025.
