Half Past Yellow announced Stream Train, a co-op horror adventure for up to six players, will launch on Steam on October 15, 2026. Players ride an old steam locomotive through the Uncanny Valley region, recording ghosts and creatures while livestreaming to viewers who can donate and send requests. Closed playtest registration is open on the Steam page. The game supports English only.
Half Past Yellow, the Copenhagen studio behind Time on Frog Island, is developing the game. Director Max Wrighton said he wanted to build a game around livestreaming as a mechanic and combined it with the friend-slop co-op genre. The closed playtest runs through Steam's internal system, and selected players can invite up to four friends via Friend Sharing. The price is undecided and the game supports English only. Players can also go solo, and the studio says the golden rule when meeting the forest's creatures is not to anger them, but if you do, at least capture the moment on camera.
