Nunholy casts players as battle-hardened nuns venturing into dungeons to hunt vampires. Its action-focused roguelike format frames each expedition around encounters with increasingly powerful foes, from Knights and Barons to Counts and Dukes. The stated goal is to track down the strongest vampires and prove yourself as an S-rank hunter.
A defining decision comes after a vampire falls: absorb its power to grow stronger, or sell that power to improve your gear. That choice sets supernatural strength against practical preparation, giving the hunt a recurring risk-and-reward tension. The dungeons also bring the nuns into contact with merchants, witches, prisoners, and undertakers, who are presented as potential trading partners rather than allies invested in the hunters’ identities.
Its appeal, as described, rests on balancing the temptation to wield the vampires’ own power with the prospect of relying on human strength, while preparing for opponents of rising rank.
