This is an old Sonic 3 glitch I used to do. You get to fight many bosses at the same time!! It's a really messed up glitch and fun to do. In this video Knuckles fights multiple Dr. Robotniks! Rockets back and forth real quick smashing them all!!
I made a few sonic boss glitch videos today. I would like to put out more of them soon. I want to work on the Super Mario glitch worlds again too! I like how this game sequence went. It's really off the wall, the graphics look kinda messed up. Don't want to give away too much in the description. Take a look at how I messed up the game! I always loved messing up these games back in the day!
