About This Retro Game
Originally started in 2005, Megamix rebuilds Sonic CD from the ground up with an entirely new engine that supports multiple playable characters (Sonic, Tails, Knuckles, Mighty, and Ray), each with unique abilities and physics. The mod features completely original zones that blend elements from across the Sonic series.
Version 4.0b introduced refined physics, additional playable characters, new special stages, and numerous quality-of-life improvements. The project stands as one of the most technically impressive Sonic fangames ever created, pushing the limits of what's possible with Sega CD hardware.
While not an official Sega product, Megamix has gained legendary status in the Sonic fan community for its professional-level polish and creative reimagining of classic Sonic gameplay concepts.
