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.

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.
