About This Game

Secret of the Sanctuary is a first-person psychological horror set on a mysterious island. The Sanctuary takes in the difficult children of the rich, and it assures every family that every care is taken.

Now something has come in the post from your childhood best friend that will set you on a course to find him.

Get inside the Sanctuary and navigate various scares, puzzles, and threats to find out how far you have to go to get the truth.

From the Sanctuary:

  • Residents will keep to their rooms from eight o'clock until morning.

  • Residents are expected to make progress. For those who will not cooperate, other accommodations are made.

  • Attendants will supervise at all times.

  • Visitors found on the grounds after dark will be treated as residents.

  • Visitation is not conducive to progress.

  • The boat does not run in poor weather.

  • Every care is taken.

Secret of the Sanctuary is made by Moth & Marrow, an independent studio making atmospheric horror.
