Spiritus Sancti

Spiritus Sancti is a first-person psychological horror game where your voice is your weapon. Speak sacred rites through your microphone to repel, stun, and exorcise the forces of darkness in real time, where every word becomes a test of faith.

You play as Father Nathaniel, a young priest sent to investigate a suspected possession in a small apartment on Vayra Street. What begins as a routine investigation quickly becomes far more sinister. The entity is released, and now it is hunting you. The apartment will not let you leave. Every attempt to escape leads back inside. The environment shifts, the presence grows stronger, and the woman you came to save is no longer only 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 and adapts, and faith alone may not be enough. The longer you remain, the more the apartment changes.
