Knuckles in Sonic 2 is the resulting game when Sonic the Hedgehog 2 is locked onto Sonic & Knuckles with its passthrough port. Sonic is replaced by Knuckles and Tails is not playable whatsoever. The title screen features Knuckles also but removes the two player mode and options selections from it. This game is identical to Sonic 2 (aside from a few changes to make it more playable with Knuckles) but with Knuckles now playable instead of Sonic or Tails.


Knuckles plays the same way he does in Sonic & Knuckles and has the same moves and lower jump height. Using his special moves, Knuckles can explore once inaccessible areas (where secrets such as 1-ups have been added). However, some areas are harder because Knuckles cannot jump very high and accelerates slowly. Some bosses are also harder, such as the boss in Metropolis Zone Act 3, as well as the final boss in Death Egg Zone. The palettes for the title cards were also changed to green and red.
