Stream Train Co-Op Horror Pits Streamers Against the Uncanny Valley
Stream Train turns the streamer's dilemma into a game mechanic, forcing players to weigh survival against the demands of an audience that rewards risk.

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.
Danish indie developer Half Past Yellow has built its reputation on experimental titles like Time on Frog Island and Tempest Tower, and its next game, Stream Train, is a direct extension of that ethos: a co-op horror game where the line between life and death is measured in viewer count. Up to six players board a steam locomotive in the Uncanny Valley, tasked with filming unidentified creatures and livestreaming the journey. The twist is that safe play leads to boring content, and boring content yields no donations. The in-game camera system recognizes specific subjects and triggers real-time chat reactions, pushing players to provoke the monsters or prank each other for the sake of a better stream. Half Past Yellow began development in September 2025, drawing from game jam experiments, and the result is a game that weaponizes the economics of live streaming against the player. Stream Train is scheduled for PC via Steam.
