5 Minute Dungeon begins with players each assuming the role of one of ten heroes, each with special cards and abilities. Players have 5 minutes to play their cards and use their abilities to defeat a monster each time they enter a randomly-selected dungeon. It is fast-paced and chaotic, and players must co-operate within the time limit to defeat monsters through each level.5 Minute Dungeon begins with players each assuming the role of one of ten heroes, each with special cards and abilities.
