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.

Metal Sonic in Sonic the Hedgehog 3 & Knuckles is a ROM hack for the SEGA Genesis that replaces Sonic with his robotic rival, Metal Sonic. It was created by a fan in the ROM hacking community and is not an official release. This hack builds on the beloved Sonic 3 & Knuckles standalone experience, swapping sprites and some animations to give players a different character to control. At its core, this is the same side-scrolling platformer as the original. You run through zones, collect rings, defeat enemies, and face bosses at the end of each act. Metal Sonic retains the basic moveset of spin dash and jump, but his handling may feel slightly different due to the sprite changes. The objective remains to reach the goal ring while navigating the familiar levels of Angel Island, Hydrocity, and beyond. For anyone who has played Sonic 3 & Knuckles to death, this hack offers a simple but effective twist. Seeing Metal Sonic in place of the blue blur adds a fresh visual layer. It is not a full overhaul or new game, but a fun change of pace for diehard fans of the series. If you have ever wanted to play through the classic as the antagonist, this is a neat way to do it.

How to play Metal Sonic in Sonic the Hedgehog 3 & Knuckles online

To begin, load the game via an emulator and press Start to get past the title screen. The game automatically starts at the first level with Metal Sonic. The core loop is the same as any Sonic game: run to the right, collect rings, avoid spikes and enemies, and reach the end of the act within the ten-minute time limit. Important mechanics include the spin jump (press the A button) to defeat enemies, the spin dash (hold B in a crouch then release) to build speed, and collecting 50 rings to access the special stages if you pass a checkpoint with them. Metal Sonic's crouching sprite may look different, but his hitbox is unchanged. There is no tutorial, so familiarity with the original game is helpful.
