Many critics supported Sega's decision to cancel the game. Game Informer commented that it looked "terrible" and "predictably awful". Computer and Video Games described it as "basically another utterly rubbish skateboarding spin-off". Similarly, VG247 called it "compellingly awful". TeamXbox, while less negative, still noted that the gameplay and level design is still pretty basic. For unknown reasons the spin-off never appeared on the internet until May 1, 2011, footage of the game was uploaded up to YouTube, which was labeled by Game Informer as a "skateboarding spinoff' video game.

UPDATE: In 2016, the demo of the game has been leaked and it's playable here.

The video showed footage of two characters, Sonic the Hedgehog and Shadow the Hedgehog. The player directed Sonic, on a board, around a skatepark, while performing tricks, with Shadow being controlled by a second player in split screen multiplayer. Three gameplay modes were present: "Mission," "Battle," and "Race". The "Mission" mode involved collecting keys in order to remove locks. The "Battle" mode involved picking up weapons, such as rocket launchers or mines, and attacking other characters. Last was a racing level, in the vein of the boarding segment in Sonic Adventure 2.
