In the wake of Sonic Forces, Dr. Eggman demolishes Green Hill Zone as bait to lure Sonic and his allies into a trap. With the heroes occupied, Eggman seizes control of an entire city, filling it with robots and androids. Players fight back as Sonic, Tails, Knuckles, Amy, and Shadow, each with a distinctive moveset, and can even take command of enemy units with their own unique behaviors. The mission: end the reign of Baldy McNosehair once and for all in this fan-made Streets of Rage crossover.
