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 ROM hack of Sonic the Hedgehog 3 for the SEGA Genesis, unofficially titled Sonic 3 - Power Of Knuckles. It's a fan-made modification that swaps out Sonic for Knuckles as the playable character, letting you experience the main campaign with the echidna's unique abilities. There's no official developer or publisher attached since it's a community creation, and its exact release date is not documented in mainstream sources. You guide Knuckles through the same zones and acts as the original Sonic 3, but with his signature moveset - gliding, climbing walls, and punching through certain obstacles. The core platforming loop remains intact: run from left to right, collect rings, defeat badniks, and reach the goal sign. Unlike the official Sonic & Knuckles lock-on cartridge, this hack might offer a standalone version with Knuckles from the start, though specifics like special stage access or level tweaks aren't widely confirmed. For anyone who's already beaten Sonic 3 and wants a fresh spin, this hack provides a solid way to revisit familiar levels with a different character rhythm. It's not a full overhaul, just a straight character swap, so it's squarely aimed at fans curious how Knuckles handles in the earlier game's level design. The niche appeal means it's worth a try if you're browsing Genesis ROM hacks, but don't expect new content or major changes.

How to play Sonic 3 - Power Of Knuckles online

Getting Started

This is a ROM hack of Sonic 3, so the fundamental goal is the same: guide Knuckles through each act of Angel Island, Hydrocity, Marble Garden, and so on. Press Start to begin from the title screen. Use the D-Pad to move left or right, and hold down to crouch. Jump with the A key, and while in the air, press the jump button again to glide - Knuckles can hold that glide for a short distance or cancel it by landing. He can also climb most walls by pressing toward them while in the air and holding the direction.

Knuckles cannot spin dash like Sonic, so you'll rely on his punch attack (B button while standing or rolling) to break items or hit enemies. Collect as many rings as possible to survive hits - losing all rings means a life lost. At the end of each act, you'll see a signpost; hitting it lets you advance. There are no multiplayer modes here; it's strictly single-player.

If you're unfamiliar with the original game, the level layouts can be tricky with multiple paths and hidden areas. Knuckles' climbing and gliding give you access to some shortcuts that Sonic couldn't reach, so experiment with vertical exploration. The hack likely doesn't include the bonus stages or the special stage ring mechanics from the official lock-on, but check every giant ring you find just in case.
