In this video tutorial, I explain how to perform a difficult glitch in Super Metroid that grants Samus a nearinfinite amount of Missiles and Super Missiles. This glitch is commonly referred to as the “Draygon ammo underflow.” You can see this glitch performed in “14% Chargeless” speedruns. The glitch takes advantage of the way the game was programmed in such a way that you essentially “trick” the Crystal Flash into draining more ammunition than Samus actually has. I go into more of the technical details in the video. I hope you enjoy!

As mentioned in the video, if you want to see a better quality image that shows the frame in which you should lay a Power Bomb to initiate the Crystal Flash, head here: https://wiki.supermetroid.run/images/...

Thanks for watching, everyone! Please let me know if you have any questions or comments.
