About This Game

In Silent Walls: Subject 13 is a first-person psychological horror narrative game.
Twenty years after the disappearance of your sister Elina, you return to the abandoned Red Hollow Sanatorium to face the past and uncover the truth hidden within its silent walls.

Explore decayed corridors, discover disturbing documents and drawings, and slowly piece together the story . Every step brings you closer to the truth… and to madness.

Because within these walls, the past is not just a memory… it is waiting for you.

Features:

  • An immersive and realistic atmosphere powered by Unreal Engine 5.

  • A dark, story-rich narrative, revealed through letters, documents, and the environment.

  • Exploration and light puzzles to progress through the story.

  • Terrifying and unsettling scenes, focused on psychological horror rather than gore.

In Silent Walls: Subject 13 is an independent, family-driven project developed in France. More than just a game, it’s the realization of a childhood dream. Thank you to everyone supporting indie horror.
