NewGen Studio and PG Publishing are getting a head start on Steam Next Fest with their demo for their upcoming train horror simulation title, Only Humans On Board. Available now, the demo allows players to experience the core gameplay loop, including resource management, passenger interactions, document verification, and the growing mystery surrounding the train and its passengers.
Only Humans On Board is a simulation game with a detective horror twist set on a train. As a train vendor, you buy your supplies, manage a snacks cart, serve passengers, and scan IDs. However, some of your “customers” are only pretending to be human. If you miss a discrepancy, the shift ends very differently.
Once the wagon door opens, the shift begins. You’ll move through the tight central aisles to see what the customers need. Serve them quickly and get paid by scanning their boarding passes. You’ll need every cent, as the money you earn will be used to upgrade your trolley for better shifts and buy the supplies that you’ll need to keep going.
Only Humans On Board will launch into Steam Early Access in Q3 2026, with the plan to remain in the service for approximately six months in order to further expand the gameplay.
