Play Sonic and Knuckles & Sonic 2 Online

Sonic and Knuckles & Sonic 2 was a 1994 release for the Sega Genesis, developed and published by Sega. It arrived during the peak of the 16-bit console era, a time when platformers dominated the market and Sega was pushing hardware innovation with its cartridge lock-on technology. This particular release was essentially Sonic the Hedgehog 2, but with Knuckles the Echidna as a playable character, offering a fresh way to experience a game many already knew well.

You control Knuckles, who moves through the same levels as Sonic but with a distinct set of abilities; he can glide through the air and climb up walls, which changes how you approach environmental navigation. The main objective remains the same: race through each stage, defeat Robotnik's badniks, and collect Chaos Emeralds. His gliding allows for longer horizontal distances and safer landings, while his climbing opens up vertical shortcuts and hidden routes previously inaccessible. The pacing feels deliberate compared to Sonic's blistering speed, encouraging more exploration of nooks and alternate paths. It feels like discovering a familiar world through an entirely new lens, full of secrets that were always there, just out of reach.
