Exvania (World)

The queen of darkness, Erinyes, has kidnapped Princess Electra. The four heroes: Ward, Emilio, Charles, and Karl embark on a quest to save the princess. They compete with each other to reach the Castle of Darkness and defeat Erinyes, so one of them might be able to marry the rescued Electra and rule the land Exvania.

The players must take up control of four medieval lords who are fighting for control of the land. They have to battle through eight different castles, and try to gain control of each one. When one of the lords wins a battle, he shall receive a medal - and once he has won three medals, he will gain control of the current castle (which means that they can be up to six rooms long) and the game will proceed to the next castle. The gameplay is similar to that of Hudson Soft's Bomberman series, the initial title of which was adapted by Irem for the arcade in 1991.
