Play Metal Sonic in Sonic 2 (Beta) Online

Metal Sonic in Sonic 2 Beta was never officially released on the Sega Genesis, but it exists as a prototype build that leaked years later. Sega developed and published the original Sonic the Hedgehog 2, and this early version gives a glimpse into their design process during the 16-bit era. It's a piece of gaming history, not a polished product, and it shows what might have been if they had kept Metal Sonic as a playable character.

You control Metal Sonic, who handles differently than Sonic; he's heavier, slides more on stops, and lacks the spin dash, making his movement feel both powerful and unwieldy. The main objective is the same as the final game: race through zones, defeat Robotnik, and collect Chaos Emeralds. Signature mechanics include his unique momentum-based physics, which require careful timing on jumps, and his ability to perform a screeching halt that sends up sparks. The pacing is frantic, and the difficulty is uneven due to the unfinished nature of the build. It feels like tinkering with a rough draft, where every dash and jump carries a sense of experimental weight.
