This game is best described as a card based co-operative dungeon exploration. Heroes of different roles and powers join together to defeat different challenges before them, and unlock the more difficult ones beyond. Every turn each hero can join in if they have a card that allows them to contribute to that particular task, pooling their dice with the ones the previous hero chose not to use. If they succeed the challenge is removed, but if you fail, you discard cards as damage. Be careful though, the cards can only be used 3 times, and after that the heroes run out of time.
