Metal Sonic (Sonic Generations)

Stardust Speedway is a stage in a boss fight of the upcoming game Sonic Generations. It is set in the Bad Future of Stardust Speedway (as evidenced by the ruined background and red sky, as well as the music) and will feature a race with the rival Classic Metal Sonic, representing Sonic CD in the game. It will be the boss stage for Chemical Plant. Unlike before there will be no normal gameplay before the boss fight. It can be accessed from the Chemical Plant Hub World. A Gameplay has been Revealed.

Gameplay
The stage begins with a cutscene of Classic Sonic being attacked by Metal Sonic in Stardust Speedway. Naturally, Sonic chases him. The whole fight is a high-speed chase, with Metal Sonic flying overhead, attacking Classic Sonic. When Metal Sonic flies close enough to the player, he/she can jump up and attack Metal Sonic, who will fall down. At some points, the ground collapses behind the player, leaving no room to slow down. It takes a few hits to defeat him. Once he is hit a certain number of times, there is a brief cutscene of Sonic try Spinning Kick and hitting Metal Sonic one last time, who then explodes.
