About

Sonic the Hedgehog 3 & Knuckles (or simply Sonic 3 & Knuckles or Sonic 3 Complete Edition) is a platform video game which is the result of locking-on Sonic & Knuckles with Sonic the Hedgehog 3 using the former catridge's unique "lock-on" technology. It is essentially a large combined game of its two lock-on components and contains all Zones from the said games and also contains special features unique to this game. This would have been the original Sonic the Hedgehog 3 the developers intended but time constraints by Sega resulted in the game being split into two.
