Overview

About this game

Sub Terra is a single-player first person psychological horror game inspired by The Backrooms. As a maintenance worker, you've spent your whole life venturing deep underground to repair pipes, gas lines, you name it. Utilities that we take for granted.

On a day like any other, you enter the manhole and descend the depths to replace a water line at the end of tunnel 04-R. The job is straightforward. The directions are clear.

But your repair doesn't go quite as planned.

  • Immersive Experience: Realistic graphics and spatialized audio create a truly immersive experience guaranteed to make you feel like you're really 50 feet under.

  • Unravel a Mystery: Piece together hints and clues to learn the tragic story of what's been buried underground.

  • Keep an Eye Out: You know the tunnels like the back of your hand, but you're not the only thing down there.

  • Locations: Your job may be down a manhole, but you'll discover much more than just maintenance tunnels.

Warning: Sub Terra contains loud noises, flashing lights and material that may be disturbing to some individuals.
