Exorcism: Case Zero

Exorcism: Case Zero is set in 1998. You play as Father Thomas Gates, called by Mary Kennedy’s father to perform an exorcism a day earlier than planned, without support from the church. Mary has been reported as possessed, and her condition is deteriorating. You must cast out the spirit before dawn, while keeping Mary alive and maintaining your own faith.

The exorcism

You can use four actions: presenting a crucifix, giving a blessing, sprinkling holy water and citing the Bible. Each has different effects on Mary and the spirit, with its own advantages and disadvantages. You can combine actions to reduce the spirit’s strength before time runs out, while preventing Mary from succumbing to the pain and stress of the ritual.

You manage Faith and Stamina, along with the spirit’s strength, Mary’s health and the time remaining before dawn. Faith helps you stay sane, while Stamina is needed to perform exorcism actions. The ritual must end before dawn, as an extended exorcism can cause Mary to succumb.

Signs of the spirit

As you progress, the environment changes, with paranormal activity, apparitions, unholy signs and other disturbances increasing. Evil apparitions and creatures can disrupt the ritual, and interactive items can help prevent them from appearing. Voice acting and subtitles accompany actions, conversations and story scenes.

Story and endings

The spirit reveals secrets when provoked, uncovering the story behind the possession. The game has multiple endings and difficulty levels, and offers multiple approaches to the exorcism.
