Metal Sonic (Sonic Generations)

Stardust Speedway is the setting for a rival boss fight in the game Sonic Generations. It is where Classic Metal Sonic is fought. It is set in the Bad Future of Stardust Speedway, representing Sonic CD in the game. The stage is located in the Chemical Plant Hub World after Sonic completes Sky Sanctuary.

Gameplay
The stage begins with Classic Sonic running through Stardust Speedway until Classic Metal Sonic destroys the road. Classic Sonic then uses the falling debris to get back up, along with jumping on top of Classic Metal Sonic. Classic Metal Sonic recovers from the blow and attempts to hit Classic Sonic,but misses. After that, the two begin to battle.

The whole fight is a high-speed chase, with Classic Metal Sonic flying overhead, attacking Classic Sonic. Classic Metal Sonic has a variety of attacks, including the Electric Shield, flying into the foreground to snap off street lights to fall on Classic Sonic, and the V. Maximum Overdrive. After Classic Metal Sonic attacks, he will be vulnerable, allowing to counterattack with a spin jump.

Classic Metal Sonic starts the fight by lunging forward at Sonic, forcing Sonic to jump out of the way. After being attacked, Classic Metal Sonic will perform an Electric Shield attack where he generates a huge amount of electricity around and directly underneath him that Sonic must avoid or attack while he's charging it. Classic Metal Sonic's next attack involves snapping off street lights to throw directly at Classic Sonic; Classic Sonic must avoid these by watching the shadows of the streetlights on the road. Finally, Classic Metal Sonic will attack with a powered up version of his first attack, which can avoided by jumping up on higher platforms. Once Classic Metal Sonic is given the final blow, there is a brief cutscene of Classic Sonic kicking Classic Metal Sonic away, who proceeds to explode.

Hard Mode
In hard mode, Classic Metal Sonic is much faster, making it harder to avoid his attacks. The order of his attacks also changes; Classic Metal Sonic snaps a total of five street lights at Classic Sonic before performing his Electric Shield attack, as opposed to two.

Trivia

 * This is the only stage in Sonic Generations which directly references Sonic CD.
 * This is one of the only stages in Sonic Generations to come from an alternate timeline. The other is Crisis City.
 * Metal Sonic's artwork on the Achievement Icon looks similar to his artwork in Mario and Sonic at the Olympic Winter Games.
 * This stage features a remix of the Bad Future music from the JP soundtrack.
 * However, a remix of the USA version of this music is an unlockable.
 * Metal Sonic's Electric Shield attack can be nullified by jumping at him while he's charging up.
 * Unlike the original, Classic Sonic cannot stop running; he also does not possess the Super Peel Out move, as Classic Sonic's gameplay is based off of the Sega Genesis games not the Sega CD.
 * The Metal Sonic race in the 3DS version occurs in Casino Night, with a layout similar to the original Sonic CD battle. This is likely the case of the 3DS's Classic era using the original layout for all of Classic's Sonic's stages.
 * Classic Amy was in the original version of Stardust Speedway in Sonic CD, but not in this version of the stage.
 * Metal Sonic can be fought as the First, Second, Third, Fourth, Fifth or Sixth boss depending on the Player's choice.
