Sonic the Hedgehog 2+ is a fan-made modification of the classic SEGA Genesis platformer Sonic the Hedgehog 2. It was created by Alex Field and showcased at the Sonic Hacking Contest expo2020. This is not an official Sega release but rather a ROM hack built upon the original game's code, intended for use on emulators or flash carts. It retains the core Genesis platforming identity while introducing custom changes.

How to Play Sonic the Hedgehog 2+ Online

Getting Started

Start a new game from the title screen by pressing the Start key. You take control of Sonic as he runs through vibrant zones. The objective is to reach the end of each act by navigating obstacles, defeating enemies by jumping on them, and collecting rings for protection. Losing all rings when hit means losing a life.

The core loop involves moving from left to right while maintaining speed. Keep an eye out for item boxes containing shields or invincibility. Familiarize yourself with the classic Sonic physics: momentum is key, and you can roll into a ball by pressing down while moving. Since this is a hack, some stages or mechanics may differ from the original game, but the fundamentals remain the same.
