'The Gizoid' is a Sonic fan-game with a difference. Playing as the Gizoid, you can unlock and choose a variety of skills and abilities from a host of characters from the Sonic universe. These skills will change the way you play through huge levels with multiple end points and unlockables along the way. You can sprint start-to-finish, fight everyone you can or go exploring to find unlockables! It's up to you how this adventure unfolds.
This demo version features the first level and a set of skills for you to play around with.
Enjoy!
