The Stadium has been conquered, enter a new arena--Pokemon Colosseum. In this innovative game, players can upload Pokemon from their Game Boy Advance games Pokemon Ruby and Pokemon Sapphire, and battle against friends on their televisions through Nintendo GameCube. With a collection of arenas to choose from, players can enter their Pokemon in a tournament or battle it out in four-player multi-battles, making each experience unlike the last. Players also can join with a friend to combine strengths in new two-on-two battles and demonstrate their Pokemon prowess as a team.
