Bakugan: Defenders of the Core puts players in direct control over towering Bakugan as they brawl among larger-than-life environments, attempting to save the world from a mysterious invading force known as the Vexos. As the only person left on the planet still able to use Bakugan in brawls, players will take direct control of 20 fan-favorite Bakugan. Between brawls, players must sneak through and explore highly guarded areas as they search for people and items which can aid them in their mission to save the Earth. In Bakugan: Defenders of the Core players can also battle against friends in the game's three multiplayer game modes.
