GAME SUMMARY

The game features levels derived from 20 years of Sonic history, spreading across three eras: Classic, Dreamcast and Modern. Each level can be played with either Classic Sonic or Modern Sonic, each taking their own routes throughout the level. 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 a gameplay style similar to more recent entries in the series, with the console versions using the 2D/3D style gameplay of Sonic Unleashed and Sonic Colors, featuring homing attacks, boosting, and the quick step and the 3DS version using the 2D gameplay of the recent Sonic Rush series. Unlike the console ports, the 3DS version will feature special stages and a multiplayer versus mode, and the majority of stages included will be different from those of the console versions. The development team is also currently considering the inclusion of stages from previous handheld Sonic titles in the 3DS version
