Play Metal Sonic in Sonic the Hedgehog (Beta) Online
Blast through Green Hill Zone as Metal Sonic—his jumps clank, his edges are sharper, and he handles like Sonic on greased wheels. Same classic levels, just with a janky, satisfying robot twist.

Metal Sonic in Sonic the Hedgehog (Beta) was an unreleased prototype for the Sega Genesis, developed by Sega. It exists as a curiosity from the early 90s, a glimpse into an alternate version of a foundational platformer.
You control Metal Sonic through familiar zones like Green Hill, but his physics are distinct; he accelerates faster and has a heavier, more metallic feel when jumping. The objective remains to defeat Dr. Robotnik, but the altered movement changes how you approach loops and enemy patterns. The game retains the core mechanics of collecting rings and breaking monitors, yet the pacing feels more frantic due to the increased speed. Playing it offers a strange, slightly off-kilter version of a game you thought you knew.
