This second Duel Masters game to reach North American GBAs continues the trading-card battle through a new role-playing story, in which players collect pieces of a lost artifact and work to solve an ancient mystery. As they compete in duels throughout the adventure, they gain new cards and build more powerful decks -- hopefully powerful enough to stand up to the game's final boss battles. Like Sempei Legends, Kaijudo Showdown follows the real rules of the table-top game, and features introductory levels that can help new players learn the game. Two cartridge-equipped Kaijudo Showdown players can battle head-to-head through a link cable connection. The initial retail release of this Duel Masters game is packaged with five limited edition cards.
