Sega of Japan has announced that it will be showing Sonic Adventure 2 for GameCube at the Tokyo Game Show linked up with the Game Boy Advance game, Sonic Advance, for the first time.
The link will enable players to train the Chao, (you know, the cute little creatures that Robitnik enslaves) on the Game Boy Advance for use in Sonic Adventure 2 via a series of mini-games.
Stay tuned for full Tokyo Game Show coverage from next week.
