Overview

Step aboard the ANOMALY EXPRESS, a train that defies logic and memory. In COMPARTMENT 666, you wake up with no recollection of how you got here, and the only way forward is to move through each compartment, inspecting every detail.

This first-person psychological horror walking simulator, developed and published by ShepherdWorks, launched on Steam on November 2, 2026. It supports multiple languages, including English, Japanese, and Simplified Chinese, and offers both single-player and multiplayer modes, along with Steam Achievements and Family Sharing.

Highlights

  • Core Mechanic – Spot the Anomaly: Each compartment may be normal or affected by an anomaly. Your job is to decide which is which, based on careful observation. A missing suitcase, an unfamiliar silhouette, or a subtle environmental change can be the clue that saves you.
  • Atmospheric Horror: The game leans into psychological tension rather than jump scares. The train setting, with its confined spaces and uncertain reality, creates a creeping sense of dread.
  • Multiple Modes and Languages: While primarily a solo experience, the game includes multiplayer options. It also offers a wide range of language support, making it accessible to a global audience.

Who It's For

If you enjoy slow-burn horror that rewards attention to detail, COMPARTMENT 666 will appeal to you. Fans of walking simulators and puzzle games will find the anomaly-detection gameplay engaging.

The game is also suitable for those who like to explore atmospheric environments and piece together a story from environmental clues. Because it's a psychological horror, it's best for players who appreciate tension over action.
