Dungeon Core puts players in charge of designing and managing a dungeon rather than raiding one, laying traps, placing monsters, and shaping corridors to repel invading adventurers. It follows the well-worn dungeon-management genre with its own set of building tools.

Balancing challenge and efficiency is central, as an overly easy dungeon invites raiders while an overly deadly one may need reworking after failed defenses. It's aimed at players who enjoy strategic base-building from the monster's side of the fight.
