This is a channel on YouTube of various Super Metroid glitches and weirdness. A lot of it is pretty deep magic, and they tend to throw around evocative terms like Murder Beam, Chainsaw Beam, and even Spacetime Beam. Those links are useful in understanding what in the burning acidic heck the narrator is talking about. Knowing and caring about the gameplay of Super Metroid is, of course, required for comprehension.
But if you do know about Super Metroid, and you do care about learning about some of the more ridiculous glitches in videogamedom, then you’re in for something that is a reasonable approximation of entertainment.
The name of the channel refers to a debug feature left in Super Metroid’s code, that can be pulled off without hyper-obscure tech, although in the process it’s likely to crash your game. When you enter into the room of the of the bosses, the Golden Torizo, if all of the face buttons are held down during the transition, your equipment will be overwritten by a number of items. The code gives you all of the beam weapons in the game, which is good, but also turns them all on at once, producing the afore-mentioned Murder Beam, which will likely crash the game, not good. The opposite of good.
Here’s links to a few of these videos: an unused enemy called a Bang, activating “God Mode,” and how to obtain and use the end-game weapon Hyper Beam against bosses. It is some pretty intense geekery, but that’s sometimes what flows out of the faucets around here.
