To trust is good; not to trust is better. Five weary warriors, on a journey for a mysterious dungeon rumored to be filled with precious gemstones. But there is hitch: ferocious monsters are guarding the gems! If the warriors join forces they can defeat them. But the coward who, blinded by his greed, will not fight seriously might get his companions punished by the monsters! The warrior who will remain loyal and will betray at the right time is the genuine hero of this game. In Dungeon Busters, the players take the role of heroes exploring dungeons and defeating monsters in search of treasures. In order to defeat a monster, every player simultaneously plays a power card face-down then reveals the values. If two or more players play the same value, they are all ignored. If players are defeated the player who played the lowest value should return some treasures as a penalty. If players succeed to defeat the monster, players can divide rewards but the player who played the lowest value will go first.
