When mysterious dimensional rifts begin tearing apart Sonic’s world and merging it with alternate realities, Sonic, Tails, and Knuckles race to uncover the cause. But the crisis is far bigger than they imagined, forcing four teams to embark on separate adventures that eventually collide.
Team Sonic races to stop the dimensional collapse, Team Dark investigates a dangerous new source of power, Team Harmony works to rescue those caught between worlds, and Team Dimension discovers that the catastrophe could alter both the past and future.
With Dr. Eggman seeking to harness the dimensional energy for his greatest scheme yet, Sonic and his allies must master new abilities, explore worlds where reality itself has been unraveled, and ultimately unite all four teams for one massive final battle.
Four teams. Twelve heroes. One adventure across dimensions.
