Roblox developer Gamefam and Sega are teaming up to create a unique Sonic the Hedgehog experience.

Sonic is getting an official game on Roblox and it has Chaos! The “speed simulator” was made by Sega of America and Gamefam and allows you run around as Sonic, Tails, and Knuckles.

A free, surprisingly good-feeling Sonic game can't go amiss with fans in need of tiding over, but some underwhelming progression holds it back.
