DUN also includes a huge narrative campaign (with a sandbox map) and many independent quests and epic events. It also allows you to design your own quests or simply to use its rulebook, system and cards to replay missions, quests, tiles and miniatures from other Dungeon Crawlers.
In other words: Dungeon Universalis is many games and one at the same time. The infinite dungeon crawler. In DUN you will find many different competitive or cooperative game modes: cooperative, lone wolf mode, Human Dark Player or Classic RPG master, always with a scalable difficulty according to the player´s level.
