The year is 1997. Pilot a small submersible into the depths of the Pacific to investigate a massive sonar anomaly. Navigate by instruments, scan targets, and uncover something far older than it should be.
The Abyss Below
SteamThe year is 1997.
Listening stations have detected a massive, non-biological sonar anomaly at the bottom of a remote sector of the Pacific Ocean. Its acoustic signature matches no known terrestrial vessel, and its exact location remains unknown.
You are sent in a small submersible to investigate possible targets, identify the source of the signal, and report your findings back to the surface.
The Abyss Below is a short PSX-style deep-sea psychological horror game about isolation, limited visibility, and discovering something that should not exist.
Visibility is almost zero, and there is no clean HUD. Use the physical instruments inside your cockpit to stay on course: sonar, depth, map, and onboard telemetry.
Follow coordinates and read sonar returns as you move through dark underwater terrain. Your front window only shows fragments of what is ahead — the rest must be understood through sound, signals, and instruments.

Reach each target, maneuver into optimal range, and use onboard sensors to send scan data back to the surface.
Each scan reveals another piece of the mystery, drawing you closer to the source of the anomaly.

Follow the trail of strange targets through the dark and send your findings back to the surface.
What begins as a search for an unknown sonar anomaly gradually leads toward something hidden beneath the seafloor. Distorted radio contact, impossible structures, and unexplained signals begin to reshape the mission piece by piece.
Something down there has been waiting for a very long time.
And every scan brings you closer to it.
