TRIVIA

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

The Japanese members of Sega Technical Institute in California developed Sonic & Knuckles simultaneously alongside Sonic 3. The two were intended to be released as a single game, but time constraints and small cartridge sizes forced Sega to split the project.

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 3 and as Knuckles the Echidna in Sonic 2 when locked on with Sonic 2.

The game was backed by a $45 million marketing campaign; at the time, video games typically had a marketing budget of $5 million. It was released around the same time as Nintendo's Donkey Kong Country. Industry figures called the coinciding releases a battle as both advertised revolutionary technological advances (lock-on technology for Sonic & Knuckles and 3D-rendered graphics for Donkey Kong).
