The First 15 Minutes of Sonic Heroes (GameCube)

Copied from MobyGames:Sonic Heroes is a 3D action-platformer in which the player takes control of a team of 3 characters, each with a special ability - speed, fly and power. The objective of the game is to race through levels as quickly as possible whilst defeating enemies and collecting rings. Your time, rings and enemies defeated make up a point system, and more points mean a higher rank on the level. There are 4 teams of characters each with their own changes to the gameplay:- Team Sonic is the intermediate difficulty featuring Sonic (speed), Tails (fly) and Knuckles (power).- Team Shadow is the hard difficulty featuring Shadow (speed), Rogue (fly) and E-123 Omega (power).- Team Rose is the easy difficulty featuring Amy (speed), Cream (fly) and Big (power).- Team Chaotix features new mission-based objectives with Espio (speed), Charmy (fly) and Vector (power).
