Fight through a world destroyed by Dr. Eggman and a powerful new villain in Sonic Forces, the new fast-paced action platformer from the team that brought you Sonic Colors and Sonic Generations. Sonic Forces lets you speed through rolling ruined landscapes as Modern Sonic, catapult past perilous platforms as Classic Sonic, and use powerful new gadgets as your own Custom Hero Character.

The game follows Sonic the Hedgehog as a member of a resistance force against Doctor Eggman, who has taken over the world with the help of his robot army and a mysterious new villain known as Infinite. Gameplay is similar to Sonic Generations with players controlling "Classic" and "Modern" versions of the titular character; the former plays from a 2.5D side-scrolling view reminiscent of the original Sonic games on the Sega Genesis, while the latter uses three-dimensional gameplay similar to Sonic Unleashed and Sonic Colors. In addition to the two Sonics, Sonic Forces also introduces a third gameplay mode featuring the "Avatar", the player's own custom character.
