A giant, decaying city in the future that is visibly under attack from forces both mechanical and supernatural. Visually resembles Westopolis from Shadow the Hedgehog. Features a streetboarding section (like City Escape from Sonic Adventure 2), but inside of a half-pipe, similar to Sonic the Hedgehog 2's Special Stage, also the board he rides appears to be an Extreme Gear. Sonic also appears to be running across flying debris in mid-air in some gameplay footage. Shadow can use an all-terrain armored vehicle in this level, similar to the Warthog from the Halo series and the Landmaster from the Star Fox series.
