遊戲簡介 / Introduction / 紹介
In 2001, Sega departed the console business to be a software publisher. Sonic Adventure 2 was ported to the Nintendo GameCube as Sonic Adventure 2: Battle on February 11, 2002. Battle has more detailed textures and additional geometry, and adds multiplayer options including new abilities, upgrades, and exclusive characters, and removes online play. Big the Cat is replaced by a Dark Chao in multiplayer mode. Battle also upgrades much of the Chao system, with a Chao's stats viewable within the game, and the option to transfer Chao from Sonic Adventure 2 Battle to the Tiny Chao Garden in Sonic Advance, Sonic Advance 2, and Sonic Pinball Party with the GameCube – Game Boy Advance link cable. If a Game Boy Advance is connected without a game, a version of the Tiny Chao Garden can be copied temporarily into the Game Boy Advance memory. This version also introduces the Chao Karate feature.
