ASSEMbler Games forum member ProtonX has discovered an unreleased game called Sonic Extreme via an Xbox development kit. The game sees Sonic try his hand at skateboarding, with gameplay much like the Tony Hawk skating games, tricks and all.
A few videos of the title in action have been released, which show Sonic skating around a stage that looks a lot like Seaside Hill in Sonic Heroes. Many fans are already speculating as to whether this could have been an early concept demo of what would eventually become Sonic Riders, which like Sonic Heroes before it, was also released on Xbox. The third gameplay video gives us a look at the game’s split-screen multiplayer mode, which features Shadow as a playable character.
Take a look at the videos and share your thoughts on the game in the comments.
