Short Description

Stream Train is a co-op adventure where up to 6 players livestream their trip through the Uncanny Valley. Grow your audience by taunting cryptid creatures, doing dangerous stunts, and pranking your friends. Can you make it through the valley alive?

Description

Livestream your experience exploring an abandoned railroad with your friends in the hopes of going viral. Investigate derelict buildings, document strange creatures, and prank your friends to keep the audience engaged in the stream because you won’t make it through the Uncanny Valley without their support and donations.

Chatters will react to whatever they see on the livestream, pose challenges, and make requests. They will also tell you when they are bored. If you keep the content flowing, chatters will keep the donations flowing.

All sorts of cryptids, ghosts, and strange creatures can be found in the forest. Try not to make them angry or at least film it when you do.

Features

• Livestreaming and content creation fantasy fulfilment
• Chat system that responds naturally to the livestream and directs the player with suggestions and bounties
• Diegetic UI inspired by mobile phones and web applications
• Simple train simulation elements give players agency to explore

History

Development of Stream Train started in September 2025. Half Past Yellow received funding support from Nimbi Game Lab almost immediately and the team hopes to convert this excitement into a great game that will capture player attention.

Half Past Yellow announced Stream Train on July 16th, 2026 at Secret Sauce Showcase. Stream Train was premiered at the event with a 60 second announcement trailer and a 60 second developer diary outlining the chat system for the game.

Half Past Yellow aims to release Stream Train in 2026.
