Adventure through the mysterious Northstar Islands in a completely new classic Sonic fast-paced action environment. Play as Sonic, Tails, Knuckles, and Amy Rose, and utilize entirely new Emerald powers to move and attack in dynamic new ways.

Navigate stunning, never-before-seen environments solo or with up to three other players. Prevent Dr. Eggman, Fang, and a mysterious new enemy from turning the islands’ giant animals into Badniks before it’s too late.

Experience fast-paced platforming and action with 3D graphics, new powers and abilities, a completely new environment, and new gameplay styles. Harness the power of the Chaos Emeralds, such as regenerating, swimming in waterfalls, shape-shifting, and much more with the powers of the Chaos Emeralds.

For the first time in a Sonic game, you can play through the entire campaign with up to 3 other players in four-player local co-op.
