Sonic 3 and Knuckles: Difference between revisions

** '''Angel Island,''': Standalone[standalone ''Sonic 3'' only:] During Act 2, enter and exit a bonus stage or special stage to remove the boundary preventing Sonic from returning to Act 1. Once back in Act 1, stand on top of the left-pointing wall-spikes under the crumbling cliff, face left and look up. While the screen is scrolled up, have Tails air-lift Sonic until the spikes are just out of sight. Let Tails descend with Sonic in tow, and he will be hurt and fall into the wall. When Tails returns, have him lift Sonic up to just below the slope above. Hop off to the right and walk over an invisible floor under the slope; he will fall through an invisible shaft, and land in Knuckles' boss area. Start to play Knuckles' Act 2 as normal, hitting the checkpoint under the breakable floor. Unfortunately, the lower boundary is locked too high, and trying to progress causes Sonic to die as though he fell into a bottomless pit. When Sonic respawns at the last checkpoint, the breakable floor returns, and he cannot escape from Knuckles' Act 2. (In ''Sonic 3 & Knuckles'', the offending checkpoint is removed.)

** '''Marble Garden''': In Act 1, as Hyper Sonic, find the only spinning top on a pedestal in the act. Head to the right, and drop into the area under the moving platforms, where the Lightning Shield is. Stand right next to the right wall, and crouch until the camera scrolls all the way down. Jump as high as you can; the game will bug out, and drop Sonic into an eerily empty version of Act 1. Go to the location of one of the Super Rings (it's the one that's normally at the end of a hidden tunnel to the right of a 1-up monitor). This will trigger the Act 2 boss fight(!). If Eggman is defeated, the timer stops and the Egg Capsule hovers down as usual, but the Capsule will be impossible to hit in this location. Since the clock has stopped, and the screen is locked in place, there is no way to lose a life. The only way out is to reset the console.
