This version has quite the changes! If you were experiencing some unnecessary lag with this stage, it should be fixed. If this does no fix it for you...
Sonic Adventure 2's Sky Rail completely redone for Sonic Generations. Except this time, it's Sonic instead of Shadow!
The main priority right now is to hunt down the decorative objects, as well some important stage geometry that is missing.
-Add breakable objects
-Find and add the rest of the stage geometry
-Finish alternate paths
-Complete layout of Red Star Rings
-Possible "modern" remix for the stage
