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

Sega has partnered with Gamefam Studios to release a 'Sonic The Hedgehog' game in 'Roblox', which will be free when it fully launches.

Those looking forward to watching the Netflix show Sonic Prime, and catch the first episode early through Roblox.

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.

SEGA and Gamefam revealed this week that the two have partnered up to bring Sonic The Hedgehog over to Roblox for a special event.

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.

"Sonic Speed Simulator is the fastest game in Roblox and features everyone's favorite speedster, Sonic the Hedgehog," reads the official synopsis.
