* It's possible to actually ''survive'' charging through the dangerous liquid that normally drains when you've killed all the metroids in an area by just having enough Energy Tanks to survive the trip, allowing you to take on most of the game's areas ahead of time. This holds little purpose outside of the novelty of being able to come back to finish the previous area off with late-game equipment, as the [[DevelopersForesight developers foresaw this]] and set the FinalBoss to not appear until you've killed ''every'' metroid.

* A glitch coined as "Pseudo Wave Beam" allows any beam shot to travel through walls ala the wave beam if you properly time doing a slide jump and bonking your head on a ceiling while shooting. Pulling this off can allow you to perform tasks like skipping the tutorial EMMI, getting the Speed Booster before getting the Diffusion Beam, and even skipping the Drogyga boss fight. This trick is also available in the demo, inadvertently showcasing another bit of classic ''Metroid'' gameplay and enabling you to fight Corpius in the demo, prior to its February 2022 update officially allowing you to reach the boss; [[https://www.youtube.com/watch?v=oq44S5BTjSk performing]] a Pseudo Wave on the explosive goop after the Save Room allowed you to continue the game from right after where the demo ended, and fight Corpius without the music and the cutscenes' sounds working - though the demo would crash and boot you back to the Switch's main menu after you collected the Phantom Cloak.

* It is possible to skip the first Torizo via the "Arm pumping" glitch, but for humans this is a PAL-only trick--Samus was made faster to adjust for the slower 50hz signal, thus letting her narrowly escape the room.

** There's also a way to do it without the Shinespark -- Samus can freeze the enemy blocking her path by using a very carefully timed and aimed Ice Missile launched from a diagonal angle. The secret message only acknowledges the Shinespark method though, as the second trick was a dev team oversight that was fixed in the European release of the game.

* Using the Scan Dash glitch allows for the Space Jump Boots to be acquired before any other upgrades. The Scan Dash was removed in later versions of Prime, so Samus must perform an alternate, but difficult method by locking on to one of the Seedlings in the Temple Hall and heading backwards to the Gunship in Landing Site, before doing the rest like the NTSC version. You can get the Morph Ball early by using this glitch.

** Do note that this is a ToolAssistedSpeedrun and not a normal speedrun. It's not entirely clear if it's RTA-viable, meaning that it could require things a human just can't do.

* Samus' [[RocketJump Bomb Jump]], which is used in her Morph Ball form. As the name suggests, it uses the knockback from a bomb's explosion in order to elevate Samus, with her being unharmed by her own bombs.[[note]]In [[VideoGame/Metroid1 the first game]], as well the original [=GameCube=] releases of ''VideoGame/MetroidPrime'' and ''VideoGame/MetroidPrime2Echoes'', it was the only way to jump in that form. Other games give Samus the ability to jump normally with the "Spring Ball" power-up at some point during her adventure.[[/note]] Since the bombs can be laid in midair and they [[SelectiveGravity don't obey gravity]], proper timing and bomb placement can allow you to chain explosions together and gain even more height. This is to the extent of a triple bomb jump (Bomb-Trick) in the ''Prime'' series, and ''unlimited'' bomb jumps (Infinite Bomb Jump) in the 2D games, making it one of the key techniques used in sequence breaking and {{Speedrun}}s throughout the series.[[note]]The only game in the series where this technique is impossible is ''VideoGame/MetroidFusion'', due to bombs functioning differently in that entry.[[/note]]
