Atrium Mortis

Atrium Mortis on PC

Atrium Mortis is a first-person psychological horror game about Arthur, who wakes from a nightmare inside his family’s long-abandoned estate with no memory of how he arrived. Someone expected him there, and you search the house’s darkest corners to learn who and why.

Light and sanity

Arthur has had nyctophobia, a fear of the dark, since childhood. In the estate, darkness drains his sanity, and witnessing things he can’t explain adds to the effect. As his mental state worsens, reality distorts.
