Sky Sanctuary Zone (Sonic & Knuckles)

Sky sanctuary is the last, second last, or third last level in the sonic 3 and knuckles games.During this level if you are knuckles you are left to fight a super strong metal sonic that can transform in to a super metal sonic.If tails you have to go through this level chasing the newly risen death egg before it gets to far in orbit. (This is the same secnario with sonic.)At the end of the level you have to fight the same metal sonic as knuckles but it is much weaker.
