Background
Sonic and Knuckles comes XBLA. Picking up where Sonic the Hedgehog 3 left off, players can now play as Knuckles for the first time. In addition, if players already have Sonic the Hedgehog 3 or Sonic 2 in their library, they will be able to access the lock-on bonus content for each game for the very first time since the days of the SEGA GENESIS! This allows for gamers to play Sonic 2 & 3 as Knuckles!
