Stardust Speedway is the sixth zone in Sonic CD. This stage's track is made up of musical instruments. If you find yourself stuck, try flipping the large signs in the foreground. Large structures loom in the background, and what's Robotnik doing back there? Remember, Metal Sonic still has Amy, too!
This level has speed boosters that make Sonic run at top speed. There are also launchers that require you to time your entrance to be fired a certain direction, but some launchers have you time a button press to get fired out. Near the end of Act 2 there is a giant building in the background. The appearance of it will be different for each time zone. If you go to it whilst in the bad future you will see a Robotnik building.
This level reappears in Sonic Generations in its bad future form, along with the original soundtrack for the bad future of this zone (with the US version being an unlockable. In Generations, this level isn't named, and is only Metal Sonic's boss battle area rather than a zone.
|“||Shoot through a maze of valves and pipes in a world of stardust and music, mind-boggling speed... and danger. Wipe out lightning bugs before they catch you in their currents. Look for certain ways to open passageways and bypass springs. Watch your step!||„|
None of Stardust Speedway's Badniks have official names besides those which appear in the game's source code, but they are:
|This zone has a lot of music-related things, and is bustling with life! Lots of wacky things can happen here.|
|Everything is calm here; it's dark and quiet. A lot of vines cover up the musical instruments; there are fewer buildings and lots of nature left. Destroy the roboticizer, or else...|
|...everything will be chaos. Most of the instruments are destroyed and left to rust and dissolve, and everything is covered in buildings like an evil metropolis. Lightning flashes in the background, and eerie clouds lurk in the sky here.|
|Freed from Robotnik's grasp, this zone becomes as bright and bustling as it should be. Crazy loop-de-loops, strange structures, and even more speed await you in this future! It would also appear that the statue of Robotnik being built in the present has been torn down.|
Metal Sonic returns in Sonic Generations as the the first Rival Battle. His battle is an "enhanced" version of the one from Sonic CD. Classic Sonic races against Metal as in the original; however, you must attack him as well as running forward. He still uses his Maximum Overdrive Attack, but he also has a super charged version of the attack, an attack in which he shoots electricity at the ground to hit Classic Sonic, and an attack in which he brakes of lamp posts that Classic Sonic must avoid. It requires four hits to defeat him.
