Sonic Generations is a 2D/3D platformer that pairs Classic Sonic (side-scrolling physics) with Modern Sonic (3D boost mechanics) across reimagined stages from the series' history. You'll replay zones like Green Hill and Chemical Plant, each presented twice—once in retro 2D style, once in high-speed 3D. The setup involves time rifts pulling both Sonics into the same timeline to stop a reality-warping threat. Boss fights pit you against remixed encounters from past games. Progression unlocks new acts and challenges. Each Sonic handles differently: Classic emphasizes momentum and rolling, Modern leans on homing attacks and boosting. If you've wondered how older level designs translate to modern speed-running, this delivers both versions side-by-side.
