The blue hedgehog is back, with a new look and all-new worlds to explore at just under the speed of sound. In SONIC ADVENTURE, players will take control of Sega's long-time mascot, Sonic, in a romp through nearly 50 beautiful, fully three-dimensional levels, which take full advantage of the powerful Dreamcast hardware. The evil Dr. Robotnik is up to his old tricks, but with the help of six playable friends including Amy Rose, Tails, and Knuckles Sonic will put an end to Robotnik's latest scheme. You can even collect tiny creatures called Chao, save them to your VMU, and play with them on the go!
