Imagine this: You’re working the night shift on a cross-country train. Your biggest worries should be restocking the stale chips, keeping the coffee hot, and dealing with the occasional rude commuter. You push your snack cart down the narrow aisle, asking for IDs and tickets.

But as you look closer at the passenger in seat 4B, you notice something is off. Their blink is a fraction of a second too slow. Their skin looks a bit too much like latex under the flickering fluorescent lights.

Welcome to Only Humans On Board, an upcoming indie simulation game that takes the mundane dread of retail and mixes it with skin-crawling cosmic horror.

The Ultimate Customer Service Nightmare

At its core, Only Humans On Board plays like a twisted love child of Papers, Please and Dead Space. Your day-to-day responsibilities look normal enough on paper:

• Inventory Management: Buy your supplies, budget your earnings, and stock your cart with the snacks passengers crave.
• Customer Service: Walk the aisles, serve refreshments, and keep the passengers happy.
• Ticket & ID Verification: Scan identification cards and check tickets to ensure everyone belongs on the train.

The catch? Some of your “customers” are only pretending to be human. They want your snacks, but they might want your flesh even more.

Spot the Discrepancy, Stay Alive

As a train vendor, your scanner and your sharp eye are your only weapons. You’ll need to cross-reference IDs, look for facial anomalies, and listen closely to how passengers speak.

If you do your job right, you flag the impostor, call security, and survive to see the next station. But if you get complacent—if you skim an ID too quickly or ignore that weird, guttural click in a passenger’s voice just to hit your sales quota—your shift ends very, very differently. Let’s just say management won’t be accepting your resignation letter.

Why We’re Hooked

What makes Only Humans On Board look so promising is how it leverages psychological tension. It turns a claustrophobic, familiar setting—a train carriage—into a gauntlet of paranoia. Every passenger interaction becomes a high-stakes puzzle where a single customer service mistake is fatal.

If you love tension-building detective games and don’t mind looking at a commuter train the same way again, this is definitely one to keep on your radar.
