** Block Shifting, which is triggered by moving vertically while mashing the Select button and causing the screen to scroll, will actually change the physical layout of the game. It so thoroughly breaks the game that it's been ruled illegal for speed runs.

** The "[[https://www.youtube.com/watch?v=BY1GVbR-A-w Invincibility]]" bug makes Samus completely invulnerable to damage (including extreme temperatures) until she enters a cutscene or another zone. This is triggered with either the "Teleporting Ball" bug, or by [[https://www.youtube.com/watch?v=T1QlaJvsQ7Y unmorphing at an E.M.M.I. zone door]] at a precise position. It also prevents Samus from bouncing off the Robot Chozo Soldiers with the Screw Attack, resulting in an instant kill when it hits multiple times.

** The "[[https://www.youtube.com/watch?v=tL-JJC35H40 Teleporting Ball]]" bug involves morphing into a ball at the right moment when Samus gets up on a ledge. It saves her position on the ledge and teleports her there as soon as she un-morphs. It can help to save backtracking time, but the biggest boon of this is that it is one of two ways to trigger the Invincibility bug.
** The "[[https://www.youtube.com/watch?v=BY1GVbR-A-w Invincibility]]" bug makes Samus invulnerable to damage (including extreme temperatures) until she enters a cutscene or another zone. This is triggered with either the "Teleporting Ball" bug, or by [[https://www.youtube.com/watch?v=T1QlaJvsQ7Y unmorphing at an E.M.M.I. zone door]] at a precise position. While this is active it also prevents Samus from bouncing off the Robot Chozo Soldiers with the Screw Attack, resulting in an instant kill when the Screw Attack hits multiple times.
** The "[[https://www.youtube.com/watch?v=Sp620pGxgp0 Camera Lock]]" bug involves refreshing the Melee Counter cutscene by reloading a checkpoint in Corpius' fight. If Samus kills the Muzby from behind before triggering the cutscene by entering the area from the front, the Muzby disappears from the cutscene and locks the camera, keeping all entities in other rooms from loading. With some skill and the Speed Booster, a player can then maneuver themselves to any other part of Artaria, use a Shinespark to deactivate this camera lock, allowing them to obtain the Screw Attack ''far'' earlier than normal.
** The [[https://www.youtube.com/watch?v=x-UJRvc0_tU Z-Axis]] bug allows Samus to end up facing the screen if she's cornered between an enemy and a wall while using the Melee Counter, allowing her to shoot towards the screen or "run towards the screen" to charge up a Shinespark, among other things. It can be used along the Invincibility bug against the Purple E.M.M.I. and a destructible wall to reach its Central Unit without the Gravity Suit.

** There's a bug that allows Samus to sometimes shoot through walls without the need of the Wave Beam by sliding, jumping out of the slide and shooting, or clipping a shot through a ceiling via proper timing when doing a wall jump. This can immensely help in SequenceBreaking and skip certain segments entirely, such as the first E.M.M.I encounter and Drogyga. This same method can also help Samus [[https://www.youtube.com/watch?v=exrfttEdJwI use the Grapple Beam on Grapple Blocks from the wrong side]].
** The [[https://www.youtube.com/watch?v=7PkX4PwKEEA "Water Bomb Jump"]] bug. Normally, trying to Bomb Jump underwater while not on the ground will provide Samus with ''very'' little lift, usually making it impossible to get higher without the Gravity Suit. However, if Samus does a Bomb Jump underwater on the ground and is uncurled ''before'' touching the ground again, a bug occurs where they will be affected by mid-water Bombs as if they were on the ground. By doing this, one can Bomb Jump and quickly uncurl before landing to initiate the bug, jump + Morph Ball + Bomb to place a bomb mid-water and uncurl again before landing, then jump + Morph Ball to mid-water Bomb Jump with ''much'' greater height than normal. This allows the player to access a good number of areas that they would not have been able to normally without the Gravity Suit.
** There's a bug that allows Samus to get extra jump height at the water's surface with the Space Jump. Normally, the game tries to limit the height of an underwater Space Jump to the max height of your first jump. However, Space Jumping near a ceiling without hitting your head on it allows you to gain a little bit of height. This seems oddly specific, [[https://youtu.be/CNUMMGCL8vs?t=37 but if used correctly you can exit a water area with a small overhang]] leading to the Screw Attack to obtain it much earlier, and thus [[spoiler:skip not only the ''entire frozen Artaria sequence'', but also ''the fight with Experiment Z-57'']].

** The "[[https://www.youtube.com/watch?v=d1uuULdnWsI Shine Sink Clip]]" bug. This allows Samus to clip through a 1-block floor if she uses a Flash Shift on a wall, then Shinespark at the right time. Normally, the game would kill Samus via TeleFrag if she happens to be inside the ground, but if the player presses certain commands that involve sliding and using the Grapple Beam, she will clip through the 1-block floor unharmed. This of course leads to several ways of SequenceBreaking, including getting the Screw Attack ''much earlier'' by performing this trick in Cataris to get to the teleporter leading to Artaria.
** The "[[https://www.youtube.com/watch?v=tL-JJC35H40 Teleporting Ball]]" bug involves morphing into a ball at the right moment when Samus gets up on a ledge. If done correctly, it saves her position on the ledge and moves her there as soon as she un-morphs. This can help to save time when needing to backtrack from an area, as long as Samus keeps in her Morph Ball form until then. However, the biggest boon of this is that it is one of two ways to trigger the Invincibility bug.
** The "[[https://www.youtube.com/watch?v=BY1GVbR-A-w Invincibility]]" bug makes Samus invulnerable to damage (including extreme temperatures) until she enters a cutscene or another zone. This is triggered with either the "Teleporting Ball" bug, or by [[https://www.youtube.com/watch?v=T1QlaJvsQ7Y using the Morph Ball and unmorphing at an E.M.M.I. zone door]] at a precise moment. While this is active it also prevents Samus from bouncing off a boss with Screw Attack, resulting in ludicrous damage when the Screw Attack hits multiple times.
** The "[[https://www.youtube.com/watch?v=Sp620pGxgp0 Camera Lock]]" bug is performed by triggering the Melee Counter tutorial cutscene against the Muzby, then loading the last saved checkpoint upon entering Corpius' room. This reactivates the Melee Counter tutorial cutscene, and when Samus returns to the Muzby later it will play out. If Samus kills the Muzby from behind before triggering the cutscene from the front, the Muzby will disappear from the cutscene and the camera will lock, keeping all entities in other rooms from loading. With some skill, a player can then maneuver themselves to any other part of Artaria with enough equipment and abilities, then use a Shinespark to deactivate this camera lock, allowing them to obtain the Screw Attack ''far'' earlier than normal.

** The "[[https://www.youtube.com/watch?v=tL-JJC35H40 Teleporting Ball]]" bug involves morphing into a ball at the right moment when Samus gets up on a ledge. If done correctly, it saves her position on the ledge and moves her there as soon as she un-morphs. This can help to save time when needing to backtrack from an area, as long as Samus keeps in her Morph Ball form until then. However, the biggest boon of this is that [[https://www.youtube.com/watch?v=BY1GVbR-A-w Samus becomes invulnerable to damage]] (including extreme temperatures) after the teleport is performed, which lasts until she enters a cutscene or another zone.

** The "[[https://www.youtube.com/watch?v=tL-JJC35H40 Teleporting Ball]]" bug involves morphing into a ball at the right moment when Samus gets up on a ledge. If done correctly, it saves her position on the ledge and moves her there as soon as she un-morphs. This can help to save time when needing to backtrack from an area, as long as Samus keeps in her Morph Ball form until then.

* In the ''VideoGame/SuperMarioAllStars'' version of the first game and ''Lost Levels'', the [[DemonicSpiders Hammer Bros.]]' hammers can't hurt you if you're on the far left edge of the screen. This has little practical use in the first game, but in ''Lost Levels'' with Hammer Bros that ''march towards you'', it helps trivializez them.

* ''[[VideoGame/BanjoKazooie Banjo-Tooie]]'' has the [[https://youtu.be/aLUlBwHmGbA Pack Jump]], which allows Banjo to DoubleJump during his Pack Whack attack. While not entirely game-breaking, it does allow quite a few shortcuts to areas.

* Similar to the above, ''VideoGame/SonicBoom: Rise of Lyric'' has a glitch where pausing the menu while in the middle of the jump [[https://www.youtube.com/watch?v=ZPwXKHqdXDw allows you to jump again]], allowing for ridiculous [[SequenceBreaking sequence breaks]] (including a 1 hour speedrun finished ''a day after the game's release'').

* ''VideoGame/Spyro2RiptosRage'' and ''VideoGame/SpyroYearOfTheDragon'' both had a few levels with the 'swimming' glitch - if you charged out of the water just ''so'' at certain points where the ground is level with the water, you can trick the game into letting you swim through the entire level. It makes finishing the stage a cinch and you can even finish a few of the challenges in a level by using this bug to cheat at them, like swimming around collecting sprockets instead of riding a cart for them.

** In ''VideoGame/Jak3Wastelander'' there's a bug that requires the Light shield and flight powers. Normally, the flight ability is more of a gliding power, only really slowing the speed and increasing the distance of falling. However, the shield power seems to suspend you in mid-air for a moment if used while jumping. So by activating Light Jak and then alternating between using the shield and flapping the wings given for flight, you can now achieve true flight. Enabling Infinite Light Jak allows you to fly ''anywhere''.

** In ''[[VideoGame/RatchetAndClankGoingCommando Going Commando]]'' you can climb most walls by going up to them in first person, jumping, and then spamming your wrench at a downwards angle.

** The battle against King Whomp becomes much easier once you know that if you jump when he falls forward on you, you'll pass straight through him and can ground-pound his vulnerable point immediately.

** The [[http://metroid.wikia.com/wiki/Door_Jump Door Jump]] which is famous enough to get its own Wiki entry. The gist of it is there is a means to use a door to clip inside a wall which can be used for both SequenceBreaking as well as accessing the game's [[MinusWorld Secret Worlds]].

* ''VideoGame/KirbysAdventure'' has a puzzle in the third level of Orange Ocean that leads to a switch that will activate an event in the HubLevel; you're faced with a cannon, which has a fuse that you have to light. The only problem is that the fuse is underwater, which means that using fire is out. In concept, you're supposed to get the Laser ability from a Laser Ball just outside the room and then shoot a laser at the (slanted) ceiling above the fuse, which will light it. In execution, however, you can also inhale a Hothead, walk over to the fuse, and then swallow it, which makes the fire from the resulting TransformationSequence light the fuse. This was fixed for ''[[VideoGameRemake Nightmare in Dream Land]]''.
** However, in ''VideoGame/KirbySuperStar'', a certain treasure chest in ''The Great Cave Offensive'' can only be reached if you know to light a fuse this way, making it an AscendedGlitch as well (although you can also get a helper to light it for you).

* ''VideoGame/MegaManX6'' is host to a multitude of different bugs, mainly due to the game's short development cycle not allowing for proper playtesting. This also results in the game being NintendoHard, and [[FakeDifficulty rarely for reasons that are fair]], but thankfully some bugs can potentially alleviate game's infamously high difficulty.
** When Zero performs an Ensuizan (the move he learns for beating Rainy Turtloid), he is completely invincible until the move is completed. However, if the animation were to be interrupted while Zero is standing on solid ground due to said ground ceasing to exist (i.e., the Ensuizan itself breaks a destructible platform underneath him or he slides off the platform he is standing on due to it being slippery), the game will think that Zero is perpetually still performing the move, rendering him completely invincible to enemies, spikes, and certain other hazards. The glitch will wear off if Zero performs the Ensuizan again, falls into a BottomlessPit, is crushed, or goes through a screen transition, such as into a boss corridor. This glitch can be performed in many different stages, most notably during the fight with ThatOneBoss, Gate.

** Input the password "[[https://www.youtube.com/watch?v=x3UyVylP7AI ENGAGE RIDLEY MOTHER FUCKER]]". The results are hilarious, if suicidal. Unfortunately, it simply freezes the system (requiring a hard reset) if done on a 3DS.

* ''VideoGame/SpongeBobSquarePantsBattleForBikiniBottom'' has the Cruise Boost, done by performing the Cruise Bubble and Bubble Bowl moves at the same time against certain walls makes [=SpongeBob=] slide forward, letting him run faster, jump farther, and get extra height with the Bash (Which lets [=SpongeBob=] jump higher but he can't move while doing it). [[https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0CB4QFjAA&url=http%3A%2F%2Fwww.youtube.com%2Fuser%2FCOEL625&ei=cBYlVInBAeup8QHNjoDwBw&usg=AFQjCNFQmr5SoW0pwRRRkb60YM1CSk5KbQ&sig2=y7FwRutSeDTIPhXLB776Uw This Youtuber]] has a series where he gets various collectibles without doing normal jumps using this trick.
** In Goo Lagoon's boardwalk area, there is a Skee Ball machine in which Spongebob can use his Bubble Bowl move (provided he unlocked it; it's rewarded after defeating a boss) to get various amounts of Shiny Objects, the currency of the game. The payout is normally incredibly small, however using Patrick to pick up and throw a pair of tikis in just the right spot inside the machine, swapping to Spongebob, and using the Bubble Bowl often leads to the ball becoming stuck in between one of the holes and the Tikis, rewarding Spongebob with the regular skee ball reward ''once per frame''. This has been dubbed "Skee Ball Abuse" and is used in certain speedrun categories due to it being a great source for Shiny Objects to easily pay for the Golden Spatulas (The primary collectibles that unlock areas and bosses) Mr. Krabs charges you for, as well as the clam gates that open additional areas for a fee.

* The [[GameEngine Hedgehog Engine]] (which was used in ''VideoGame/SonicUnleashed'' and ''[[VideoGame/SonicGenerations Generations]]'') works by [[DynamicLoading loading the textures of the next part of the level when the player hits loading triggers]]. When playing the game normally, you get detailed levels that load seamlessly and without texture pop-in. However, if you're a SequenceBreaking {{speedrun}}ner, sometimes you will miss one of these triggers, and now your supersonic hedgehog can add [[https://www.youtube.com/watch?v=qmpc8lOkMTY#t=495 walking on air]] (some explanation of how this works can be heard [[https://www.youtube.com/watch?v=qmpc8lOkMTY#t=431 here]]) to his list of superpowers until you hit the next one.

** The life underflow glitch. Taking damage at the right moment while drowning can cause you to lose 2 lives instead of 1, and if this happens when you're on your last life, the game will [[FissionMailed appear to end... and then resume]], with the number having looped back around to 255 lives, although the life counter can't display numbers that massive correctly correctly (even when gained in [[InfiniteOneUps non-glitchy ways]]).

*** The four main bosses: [[spoiler:It's possible to use the door to the statue room in a way that clips you underneath the statues, putting you on the elevator and letting you bypass the requirement to kill them.]]

*** Kraid: [[spoiler:If timed correctly after the initial missile shot to the mouth, the player can switch to super missiles and pump three rapidly into Kraid during his damage animation. it is possible to kill him before he lifts out of the ground with this glitch.]]

*** The four main bosses: [[spoiler:With a recently discovered door glitch, it's possible to enter Tourian without defeating them.]]

* ''VideoGame/SuperMetroid'' has the incredible Murder Beam (also known as Space/Time Beam or Spazma Beam), a bug caused by activating the Spazer Beam and Plasma Beam simultaneously (needs pretty good reflexes or dexterous fingers). In most locations, firing this weapon will cause everything to slow down and fade to black as the game crashes. In some places, though, the game does not crash but just causes minor graphical glitches instead. This includes the final boss fight, where using it causes the boss to move slower, making the fight a bit easier. If you save after using the beam in a safe spot and reload, the game will be reset back to the very beginning, at the Space Colony. All upgrades (except missiles) are retained, however, allowing you to beat the crap out of the early bosses with weapons that kill them in one shot and obtain up to 900% completion.
** What the Murder Beam does is that it creates a vertical wall of damage, and anything in the wall takes constant streams of damage. But the only way to fire it without crashing the game is by firing a charge shot Left. Since you have to fire once to start charging, you have to pause the game, hold the fire button, and unpause it to charge without firing an uncharged shot, and fire left. Since Mother Brain is the only boss in the game that consistently stays to the left of you, she's the only one it's really effective against.
** The wave/spazer/plasma combo results in the Chainsaw Beam, which has an absolutely amazing rate of fire, but only affects beam-destroyable blocks (it can't hurt enemies).
