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.

Sonic 2 with Knuckles v1.1 is a rom hack of the SEGA Genesis classic Sonic the Hedgehog 2. This fan-made modification places Knuckles the Echidna into the main game, replacing Sonic and Tails for single-player. The hack was created by an unknown author and released as a downloadable patch. It is not an official Sega product but a labor of love from the retro modding community. As Knuckles, the player runs through the familiar zones of Sonic 2, but with unique abilities. Knuckles can glide through the air by pressing the jump button in flight, and he can climb walls by pressing up against them. The core loop remains the same: collect rings, defeat enemies, and reach the goal ring before time runs out. The special stages are also modified to accommodate Knuckles' handling. For anyone who has played through Sonic 2 dozens of times, this hack offers a fresh perspective. Knuckles' different physics change the flow of each level, making even the most familiar sections feel new again. While it lacks the two-player mode of the original, it is a solid alternative for solo players who want a different challenge. The v1.1 release fixes some bugs from earlier versions, making it a stable choice.

How to play Sonic 2 with Knuckles v1.1 online

To start, select 'New Game' from the title screen. You will take control of Knuckles immediately. The game follows the same level order as Sonic 2. Use the D-Pad to move left and right, and press the jump button (X) to leap. Knuckles can glide by pressing jump again while in the air. To climb walls, hold the D-Pad toward a wall while in contact. Avoid spikes and enemies, and collect rings to survive. The special stages are accessed by collecting 50 rings and jumping into the giant ring at the end of a zone. Practice the glide timing to reach high platforms. The core strategy is similar to Sonic 2: maintain speed and gather rings. Knuckles cannot spin dash, so his ground speed is slightly slower than Sonic's, but his aerial mobility makes up for it. Use climbing to bypass obstacles and find secret areas. The game ends when all zones are completed. If you are new to this hack, start with Emerald Hill Zone to get used to Knuckles' controls. The level design remains unchanged, so memorized players will know where to go. Just adapt to the different physics.
