Stream Train Co-Op Horror Pits Streamers Against the Uncanny Valley
Half Past Yellow announced Stream Train, a co-op horror game for up to six players on PC. Set in the Uncanny Valley, players board a steam locomotive, film supernatural creatures, and livestream their journey. The game's core mechanic forces players to choose between safety and creating viral content, as viewer counts and donations depend on dangerous stunts and pranks. Real-time chat reactions and viewer requests add pressure. Release is planned on Steam. Half Past Yellow, a seven-person Danish studio, has previously won four awards with titles like Time on Frog Island. Development began in September 2025.
