Dungeon Keeper 3: War for the Overworld is a cancelled PC strategy game by Bullfrog Productions for Microsoft Windows. Dungeon Keeper 3 was set to be the next installment in the Dungeon Keeper franchise. Players were charged with managing evil creatures in an underground dungeon and protecting it against the stereotypical righteous and goodly adventurers that conventionally appear in role-playing video games. The series won praise from reviewers for its innovative design and devilish humor.
