Sonic and the Mayhem Master is a fanmade RPG game that is based on the Sonic Storybook series. The game offers a new look that fits to the aesthetic of the genre. Explore the world of steampunk, as weird things are about to happen. Solve cases with your sugar-freak partner, and find out the truth of this mechanical city.

The game was eventually rebranded, losing the ties to Sonic the Hedgehog, retitled as Mekanikko.
