Unholy invites players to explore two parallel worlds: the grim, brutalist reality of a post-Soviet Eastern European town and the dark, grotesque world of Unholy, ruled by a merciless caste of priests. Players must navigate between these two realms to find clues, solving mind-bending puzzles and deciding whether to infiltrate the nightmarish reality with stealth, or to engage in full on brutal combat against the twisted denizens that rule the two worlds.
