It is up for Sonic and Tails to stop the evil scientist. Robotnik carries out his plans to repair the damaged Death Egg and launch it into space to bring chaos to the world. The conclusion to the grand Death Egg saga, Sonic 3 & Knuckles is set on the Floating Island, where Dr. Sonic 3 & Knuckles is the original Sonic the Hedgehog 3 the developers originally intended to release to the public but time constraints and manufacturing costs by Sega resulted in the game being split into two separate titles.

It is essentially a large combined game of its two lock-on components which contains all Zones from the said games and also contains special features unique to this version. Sonic the Hedgehog 3 & Knuckles ( ソニック・ザ・ヘッジホッグ3 & ナックルズ, Sonikku za Hejjihoggu Surī to Nakkaruzu ?), also known as simply Sonic 3 & Knuckles ( ソニック3 & ナックルズ, Sonikku Surī to Nakkuruzu ?), is a 1994 platform video game in the Sonic the Hedgehog series made for the Sega Genesis/Mega Drive, which is the result of combining Sonic & Knuckles with Sonic the Hedgehog 3 using the former cartridge's unique lock-on technology.
