Confront a malevolent force that threatens the future of the world in Lost Kingdoms, the first real-time action RPG for the Nintendo GameCube. Players experience the game through the eyes of a beautiful heroine, Princess Katia, on a quest to rid the land of a deadly menace intent on engulfing the five Kingdoms of Argwyll. During the adventure, you must find and gather the cards that hold the power to unleash incredible creatures into battle while fighting off the endless hordes of monsters that stand in your way.

Throughout the game, players will explore more than two dozen graphically rich 3-D worlds as they uncover the mystery that threatens to destroy the five Kingdoms of Argwyll. Along the way, gamers have the opportunity to collect more than 100 unique Guardian Cards that can be used to release powerful creature allies such as fighting skeletons, ravaging wolves, and fire-breathing dragons. Each creature has its own special attack moves, which increase in range and power as Katia gains experience.

In addition to the single-player story mode, players can take on friends in two-player versus mode, pitting the creatures in their Guardian Card collections against one another in a battle to the finish
