Sonic 3 & Knuckles is a singleplayer and multiplayer side view scrolling platform game co-developed by Sonic Team and Sega Technical Institute and published by Sega. It is part of the Sonic the Hedgehog series.

Originally released on Sega Genesis in 1994 as a combined title of two separate games (Sonic the Hedgehog 3 and Sonic & Knuckles), it was ported to PC and released on January 26, 2011. Unlike the version included in Sonic & Knuckles Collection which runs native on Windows, this version is an emulated re-release.

The game was eventually delisted on all storefronts on May 20, 2022 in preparation for the release of Sonic Origins.

Essential improvements

Sonic 3: Angel Island Revisited

Sonic 3 A.I.R. is a fan project aimed at making an accurate, reverse-engineered PC port of Sonic 3 & Knuckles. It includes a number of graphical improvements such as 16:9 widescreen (can be changed back to 4:3 or other aspect ratios; see Ultra-widescreen), consistent frame rate, 60 FPS in special stages, smooth sprite rotation, and mod support. It requires a Sonic 3 & Knuckles ROM identical to the Steam release[Note 1]; ROM hacks (modified ROMs) are incompatible.

Restoring the original zone order and features:

  • Original Zone Order - Places Flying Battery in-between Carnival Night and IceCap, as intended prior to the game being split in two in the original release
  • Sonic 3 Complete FBZ Night Palette - Improves continuity with the original level order by porting the Sonic 3 Complete night time palette for Flying Battery Zone.
  • FBZ Doorboarding - Replaces the snowboard in Icecap Zone with the door from Flying Battery Zone to create better continuity between Zones.
  • Knuckles Fights the Carnival Night 2 Boss - This mod forces Knuckles to fight the boss in Carnival Night Zone Act 2 instead of skipping it as he normally does. Incompatible with Original Zone Order.
  • Launch Base Zone Eggman Fleeing Recreation - Re-creates an unused animation where Dr. Eggman flees after Big Arms is defeated at the end of Launch Base Zone Act 2.
  • Sonic 3 Complete Launch Base Zone Transition - A mod that ports the Death Egg falling onto Angel Island transition sequence from Sonic 3 Complete in between Launch Base Zone and Mushroom Valley Zone into Sonic 3 A.I.R..
