Free 3D Sonic game
Sonic Utopia is an adventure PC game developed by Mr. Lange that features Sonic the Hedgehog. This free-to-play game imagines the most famous hedgehog in an open-world setting. Here, you will control Sonic as he moves past various obstacles at supersonic speed.
Sonic Utopia is a fan-made game. Unlike other Sonic titles, it puts players in a completely three-dimensional environment. Despite that, however, it maintains the fidelity to classic scenes from the 8-bit console era. All the elements of Sonic: the Hedgehog are also present. This game is still in the raw demo stage so expect a short run time.
