Once a big city like Cyan City Zone, now in ruins. No one knows what happened, but some say it was some huge explosion. Somehow, some buildings were left untouched. Many restoration efforts were made on the city, but no one managed to restore the city completely. Sonic & Friends go to explore the city....

Somehow the save glitched out and didn't save all the changes I made to the buildings. Whatever, I'll post a follow up when I have the motivation to do it again.
