Play Sonic the Hedgehog 2 (World) (Beta) Online

Blasting through Chemical Plant Zone at full speed, barely dodging Robotnik’s traps while Tails either helps or gets stuck in a wall—pure Genesis chaos. Those half-pipe bonus stages still mess with your thumbs, but you keep chasing emeralds anyway.

Game Overview

Sonic the Hedgehog 2 (World) (Beta) is an early version of the game developed by Sega for the Sega Genesis, released in 1992. It captures the platform's energetic style, with colorful levels and fast movement that defined many games of that era. This build shows some differences from the final release, offering a glimpse into the development process.

You control Sonic, often accompanied by Tails, as you run through zones, jump on enemies, and collect rings. The main goal is to stop Dr. Robotnik by completing acts and defeating bosses. Signature mechanics include the spin dash for quick acceleration, special stages where you run through half-pipes to collect Chaos Emeralds, and cooperative or competitive two-player modes. The pacing is brisk, with occasional slowdowns in this beta, and the difficulty can spike unexpectedly. It feels like a rough but exciting preview of what would become a refined experience.
