It's the expansion of Dungeon Star Dungeon Star It's changed to the corporate rule to be arranged from the original version by Kenichi Tanabe. The system is based on the original rule. The components are only 20 cards. The players make the party for the dungeon of the hell imaged in Japan. The turn player rolls the special dices with a few V mark, when he/she gets two or more V mark, the party marker advance the dungeon. The rolled dices will be changed to more difficult. Then the players will battle with the bosses. The players have the special activities, and will be up the level. So the player can use more special activities. It's like the Japanese RPG. However, it's kept the corporate board game. The player's HP is nothing. All are needed the V mark of dices.
