The game features levels derived from 20 years of Sonic history, spreading across three eras: Classic, Dreamcast and Modern, which are played as either Classic Sonic or Modern Sonic. Classic Sonic's levels are strictly two dimensional side scrolling stages, using classic moves like the Spin Attack and Spin Dash, while Modern Sonic's levels follow the 2D/3D style gameplay of Sonic Unleashed and Sonic Colors, featuring techniques such as boosting and homing attacks. As well as classic power-ups such as Invincibility and Speed Shoes, certain levels have unique power-ups, such as skateboards in City Escape and Wisp powers in Planet Wisp.
