Sonic The Hedgehog (World) (Proto)

What is Sonic The Hedgehog (World) (Proto)?

Compiled by the · Updated

This is a prototype build of Sonic the Hedgehog for the Sega Game Gear, discovered as a pre-release version of the handheld port. Developed and published by Sega, the final Game Gear version launched in 1991, but this early build offers a glimpse into the development process. The game belongs to the platforming genre and was initially created as a companion to the Mega Drive/Genesis original, adapting its high-speed formula for the smaller screen.

How to Play Sonic The Hedgehog (World) (Proto) Online

Getting started: In this prototype, you control Sonic through early versions of Green Hill Zone and other levels. The goal is straightforward - reach the end of each stage by running, jumping on enemies, and collecting rings. Avoid spikes, pits, and Robotnik's badniks. Rings act as a shield; losing all rings costs a life. As a prototype, some level layouts or enemy placements may differ from the final release. You may also encounter debug tools or incomplete areas. Use the D-Pad to move, X to jump, and S to spin-dash (hold S, then release after charging). Experiment with the controls to find any hidden developer options that might be present.
