SUBSELF: Lies Deep announced. Descend into the depths during Steam Ocean Fest and uncover what should have remained forgotten

SUBSELF: Lies Deep, a psychological underwater horror game set in the depths of an alien ocean, has officially been announced for PC via Steam. Players can experience the first playable demo during Steam Ocean Fest.

In SUBSELF: Lies Deep, players descend into the remains of a mysterious underwater research facility abandoned after a catastrophic incident. What begins as a recovery mission quickly turns into a disturbing journey through flooded corridors, forgotten experiments and traces of a truth buried beneath the ocean floor.

Armed with limited equipment and guided only by fragmented transmissions, players must explore oppressive deep-sea environments while managing oxygen, navigating darkness, and confronting the psychological effects of prolonged isolation beneath the surface.

The game combines atmospheric exploration, narrative-driven horror, environmental storytelling, and survival mechanics, placing a strong emphasis on tension and immersion rather than direct combat. The deeper players descend, the more reality itself begins to fracture.

Will you discover what should have stayed forgotten?

KEY FEATURES:

  • Explore a haunting underwater research complex hidden beneath an alien ocean.
  • Experience psychological horror inspired by deep-sea isolation and cosmic dread.
  • Manage oxygen and resources while surviving hostile underwater environments.
  • Uncover fragmented logs, recordings, and hidden secrets connected to the station’s downfall.
  • Descend into increasingly oppressive depths where perception and reality begin to blur.

The first public demo for SUBSELF: Lies Deep will be available during Steam Ocean Fest. Players can already wishlist the game on Steam and watch the newly released announcement materials.
