>>35731853Genocide City was going to be called Cyber City in the final, and would've had a unique tileset while still using the Metropolis Act 3 layout (Presumably the stage gimmicks and enemies would be different? Not really sure what would've happened since I think Metropolis Act 3 is based around the unique triangle bumpers that had already appeared in Acts 1 and 2. Every zone has unique enemies so Cyber City would be breaking the pattern if it didn't.) Cyber City's tileset was used in a Sonic Spinball stage, and so was part of Hidden Palace repurposed as a background in another stage.
