Spiritus Sancti
SteamSpiritus Sancti is a first-person psychological horror game centered on ritual, faith, and the power of the spoken word.
You play as Father Nathaniel, a young priest sent to investigate a suspected possession inside a small apartment on Vayra Street. What begins as a routine investigation quickly turns into something far more sinister. The entity is released. And now it is hunting you.

The apartment will not let you leave.
Each time you try to escape, the door leads you back inside. The environment shifts, the presence grows stronger, and the woman you came to save is no longer just a victim. She is the vessel.

Your only defense is the sacred language of the ritual.
Using your microphone, you must speak invocations aloud to repel the demon, weaken its influence, and survive the encounter. But the entity learns. It adapts. And faith alone may not be enough.
The longer you stay, the more the apartment begins to change.

Key Features
Voice-Driven Exorcism Your microphone is an essential part of the gameplay. Speak ritual invocations to repel the entity, disrupt attacks, and perform sacred rites.
A Living, Shifting Apartment The environment loops and evolves as the presence grows stronger. Familiar spaces slowly become something else.
Psychological Horror Focus No weapons. No safe rooms. Only ritual, observation, and your voice stand between you and the entity.
Unpredictable Encounters The possessed roams the apartment, hunting you through the dark. Every confrontation becomes a test of timing, faith, and nerve.
