Unofficial ROM hack. The notes below come from community sources and have not been verified against the patch itself, so levels, mechanics and features may differ from what is described.

This is a fan-made modification of Sonic 3 & Knuckles for the SEGA Genesis, often referred to as "Sonic 3 & Shadow." It was created by the ROM hacking community - no official Sega involvement - and released online sometime after the original game's 1994 launch. The hack replaces the standard Sonic sprite with Shadow the Hedgehog, giving players a new visual and gameplay twist on a classic platformer. At its core, the game plays just like the original Sonic 3 & Knuckles: you run through side-scrolling levels, collect rings, defeat enemies, and reach the goal ring at the end of each act. The main difference is that Shadow handles very similarly to Sonic - he can spin dash, jump, and use elemental shields, but some versions tweak his speed or jump height slightly. The level layouts remain unchanged, so veterans will recognize every zone and boss pattern. For fans of the series, this hack offers a fresh way to replay the beloved master Sonic 3 & Knuckles. It's not an official release, but the attention to spriting and the novelty of controlling Shadow in a classic engine makes it a neat curiosity. If you've played the original to death, swapping in a different character can breathe new life into familiar stages without changing the core challenge.

How to play Sonic 3 & Shadow online

Getting Started

When you boot up the game, you'll see the SEGA screen and then the title screen - press Enter to start. From the menu, you can choose between Sonic & Tails, just Tails, or just Knuckles in most versions; since this is a hack, the character select may be modified. Use the D-pad (arrow keys) to highlight an option and press X (A button) to confirm.

The core loop is pure Sonic: run from left to right through each act, collect rings (they protect you from one hit), smash badniks, and reach the giant ring at the end. If you hold down on the D-pad and press X or S, you can spin dash. Coins let you roll into enemies faster. Watch out for spikes and bottomless pits - one mistake and you'll lose your rings, followed by a life if you get hit again without any.

Because this is a fan hack, menus and text are in English (assuming you're playing the common version). There are no difficulty settings or language options to worry about. Just jump in and enjoy a familiar run with a different character.
