A complete conversion of Sonic Adventure 2 from the Dreamcast, with exclusive Gamecube features.
Play through 150 missions as Sonic, Knuckles, and friends or the evil crew of Dr. Robotnik, Shadow, and Rouge (30 levels in total). As Sonic’s team, you must prevent Dr. Robotnik from gaining control of the Chaos Emeralds. In contrast, Dr. Robotnik’s team must keep Sonic at bay while collecting all of the Emeralds to gain complete control of the planet.
Improved visuals, new two-player battle games (including Kart Racing, Hunting, and Chao Karate), and the ability to grow your Chao and exchange them for portable training are exclusive to the Gamecube.
