Sonic & Knuckles (World)

Sonic & Knuckles platform overview

Sega blasted its platforming formula into the stratosphere with this 1994 Mega Drive knockout, building directly on Sonic the Hedgehog 3's cliffhanger ending. What elevates this sequel beyond mere nostalgia is the well-known cartridge 'lock-on' technology, physically letting you plug other Sonic classics into its top—a design quirk modern hardware can barely conceive. Its vibrant 16-bit aesthetic remains breathtaking. Sonic & Knuckles includes region marker: World, which helps separate this page from nearby ports, regional releases, and similarly named entries.

• Innovation You Could Hold
  Locking on a Sonic 3 cartridge merged both games into the epic 'Sonic 3 & Knuckles', while plugging in Sonic the Hedgehog 2 let you drop Knuckles into that entire adventure, creating two games in one in the most tactile way.
• A Dual-Track Classic Campaign
  The full old-school journey splits into two distinct experiences: blitz through iconic zones like Flying Battery with Sonic's raw speed and elemental shields, or uncover new pathways as Knuckles using his climbing punch and slow-gusty glide.
• A Soundtrack and Spectacle Peak
  From the oppressive percussion of Lava Reef Zone's first act to the dizzying ascent of Sky Sanctuary's floating ruins, this game delivered some of the sharpest pixel art and slickest sound chip masterworks of its entire generation.
