Sonic & Knuckles for Mega Drive was released on October 18, 1994 in Japan.

Sonic & Knuckles utilizes 'lock-on technology' that lets the cartridge plus the Mega Drive access data from Sonic the Hedgehog 2 and Sonic the Hedgehog 3 so that elements of both Sonic & Knuckles and the locked-on game are combined. To play these combined games, the hatch on top of the Sonic & Knuckles cartridge can be flipped open and the second game placed inside.

This game is known as "Sonic 3 & Knuckles" when locked on with "Sonic the Hedgehog 3".
