Someone should have warned the Covenant children never to read aloud strange rituals. Their childish game unleashes unspeakable horrors, and years later Jeremiah Covenant, the last sane sibling, lies on his deathbed knowing his fragile existence is the only thing restraining the curse.

Patrick Galloway, a soldier from the Great War and a specialist in abolishing evil abominations, is called in to help. Players step into his shoes as he faces curses, strange creatures, and family dysfunction gone wrong.

The game combines first-person shooting with arcane magic and a six shooter. It is described as a horrifying FPS romp set in a world of mad creatures and evil abominations.
