Sub Terra

Sub Terra is a single-player first-person psychological horror game inspired by the Backrooms. You play a maintenance worker who has spent a lifetime going underground to repair utilities such as pipes and gas lines. On a routine job, you descend through a manhole to replace a water line at the end of tunnel 04-R, but the repair does not go as planned.

Explore underground

The tunnels are familiar from your work, but you are not alone down there. You venture beyond the maintenance tunnels and piece together hints and clues to uncover the tragic story buried underground.
