Item Condition
Game only: the cartridge in a protective holder, no box or manual. For the specifics, look to the photos — they're of this exact cartridge. Every cartridge's shell, label and board are checked for authenticity when it comes into the store, and it's tested before it's listed. It ships in a collector's bag or a hard plastic case.
Item Description
Sonic & Knuckles is the cartridge with a door in its roof. Open the hinged flap on top and you find a second slot, Sega's Lock-On Technology, and what you plug into it changes the game entirely. On its own, it finishes the story Sonic the Hedgehog 3 began; with Sonic 3 attached, the two halves join into one of the biggest and best adventures of the 16-bit era.
Played by itself, it picks up on Angel Island as Dr. Robotnik races to relaunch the Death Egg. You can take Sonic, who still draws special moves from his elemental shields, or Knuckles, starring for the first time, who glides across gaps, climbs walls and smashes through rock to reach routes Sonic can't. The zones are a classic-era highlight reel: the autumn woods of Mushroom Hill, the airship Flying Battery, the sinking sands and haunted pyramid of Sandopolis, the molten caverns of Lava Reef, the mysterious Hidden Palace, the floating ruins of Sky Sanctuary and the Death Egg itself, with Knuckles' story following its own path to its own final showdown.
Lock-On is where the legend grew. Attach Sonic 3 and you get Sonic 3 & Knuckles, the complete adventure, with Knuckles playable through Sonic 3's zones, Super Emeralds and Hyper forms to chase. Attach Sonic the Hedgehog 2 and you can play that entire game as Knuckles, his glide and climb opening fresh routes through familiar zones. Even the original Sonic the Hedgehog unlocks something: a seemingly endless supply of Blue Sphere bonus stages. No other Genesis cartridge did anything quite like it.
That makes Sonic & Knuckles more than a sequel. It is a clever piece of Sega hardware design and the key that completes the Sonic 3 story. With Sonic 3 on hand, this is the half that makes it whole, and with Sonic 2 it turns an old favorite into a brand-new way to play.

About the game
Sonic & Knuckles is a side-scrolling platform game that continues the events of Sonic the Hedgehog 3.

Players can control either character through a series of zones, collecting rings and Chaos Emeralds while defeating enemies and bosses. Knuckles can glide, climb walls, and break certain obstacles, while Sonic can use abilities granted by elemental shields.
