Dungeon Overlord is a pleasant surprise of a game. The overall play style is similar to other Facebook grand strategy games like Kingdoms of Camelot, but Dungeon Overlord is more than a new fantasy wrapper around an old gameplay format. Dungeon Overlord also draws inspiration from an older PC title called Dungeon Keeper, where the player is an evil overlord who has to build and defend a dungeon. Dungeon Overlord ups the ante, letting you conquer nearby dungeons and fight other overlords for supremacy.
