About the game
Sonic Adventure DX is the expanded version of Sonic Team's 3D platformer. Dr. Eggman has woken an ancient evil sealed inside the Master Emerald, and with the seven Chaos Emeralds it could grow into the ultimate monster. Sonic and his friends set out to stop it. The story is told through six playable characters, including Sonic, Tails, Knuckles and Amy, and each has their own adventure with its own perspective on events and its own style of play. Between the action stages you can raise and care for your own pet Chao in the Chao Garden, then enter it in races and contests against other Chao.
