Gameplay FAQ

What should I know before playing Sonic & Knuckles?

'Lock-on Technology' was the cartridge's unique physical design letting gamers plug Sonic 2/3 carts directly into it, thereby unlocking Knuckles as a playable character in those entire games – a groundbreaking feature for cartridges and physical content in 1994.

Do I have to own or pair Sonic 3 to play Sonic & Knuckles?

No, Sonic & Knuckles is a full-length standalone platforming adventure that can be played without attaching anything. However, pairing with Sonic 3 unlocks its combined version known as 'Sonic 3 & Knuckles', and attaching Sonic 2 allows you to play through a 'Knuckles in Sonic 2' mode.

How should beginners approach Sonic & Knuckles?

Beyond the aesthetic, Knuckles is a very different character. He's slower and cannot roll into a ball by default but has powerful punches, can glide in mid-air to reach new areas, and can slowly scale almost any vertical surface, offering a distinct exploratory play style.

How does the story connect?

The game picks up immediately after the Sonic 3 cliffhanger where the Death Egg falls back to Angel Island. This final chapter in the Super Emerald saga sees Sonic and often-reluctant ally Knuckles uniting to prevent a fully operational Death Egg from being resurrected.

How do the Special Stages and Super transformations work?

Giant Rings throughout levels grant access to fast mini-game Special Stages to find new 'Super Emerald' keys. Successfully combining all seven Chaos Emeralds from previous entries and all seven Super Emeralds from this game unlocks the ultimate Super forms for Sonic and Tails/Shadow for Knuckles.
