Background:
It's Sonic Adventure 2, the latest Sonic masterpiece, where you play as Sonic, Tails, or Knuckles and attempt to save the world-OR-play as Shadow, Dr. Robotnik, or Rouge and conquer all who stand in your way. Mistaken for a villain and kidnapped by a military squad, Sonic must escape his captors and discover who is responsible for all his trouble.

Gameplay:
Two new playable characters enter the Sonic universe -- a mysterious dark hedgehog called Shadow, and a jewel-thieving bat named Rouge. In the single-player mode, you’ll go through more than 30 unique stages, which include everything from a forgotten pyramid, an abandoned military base, and a giant space station. Then there’s the expanded two-player mode, which features 12 playable characters competing in new head-to-head games. All of this adds up to Sonic’s biggest adventure yet
