  • Descend into the abyss Rely on your sonar to navigate the darkness and reveal what lies hidden beneath.

  • Face the impossible Experience the first effects of the Sanity System, where perception itself becomes unreliable.

A clean slate for launch

To ensure the best possible experience at release, progress from the demo will not carry over to the full game. We want every player to begin their journey under the same conditions when the full experience launches.

Thank you for your continued support.

The abyss is open - but only for a limited time.
