Dive into Sonic & Knuckles for Sega Genesis: The epic finale to Sonic 3! Experience revolutionary lock-on tech to play as Knuckles in Sonic 2 or merge with Sonic 3 for one massive adventure.
Sonic & Knuckles (World) is the thrilling conclusion to the Sonic the Hedgehog 3 saga, released for the Sega Genesis. This iconic platformer introduced revolutionary "lock-on technology," allowing players to physically connect other Genesis cartridges (like Sonic 2 or Sonic 3) to unlock special content. When combined with Sonic 3, it creates an expanded adventure called "Sonic 3 & Knuckles," while attaching Sonic 2 lets you play as Knuckles in that game. The standalone game follows Sonic and Knuckles as they race through vibrant zones to stop Dr. Robotnik from harnessing the power of the Floating Island.
