* [[https://ki-no-shirayuki.dreamwidth.org/18419.html A selection of several cases from]] ''VideoGame/ToukenRanbu'', which includes such gems as swords saying other swords' lines, swords turned into ''[[AttackOfTheFiftyFootWhatever giants]]'', an ''enemy'' being the MVP and, in a chilling moment of BreadEggsMilkSquick, a sword who has only sustained serious damage being displayed as ''[[FinalDeath dead]]''.

'''Danny:''' So what you're telling me is if you fucking carry bowls around you can walk through walls? [[CrazyAwesome That is the stupidest most awesome thing I've ever heard!]]

While professional players of single-player games like speedruners are usually allowed to use glitches to clear games faster, they often have a sort of code of honor of making a separate category where you're not allowed to use glitches to [[SequenceBreaking skip parts of the game]], although discerning glitches from unmentioned game mechanics can sometimes be controversial. In online multiplayer games, exploiting glitches for your advantage is often considered the same thing as cheating and in some cases may even lead to your account being banned, but in other cases glitches may instead be treated as unintended but fair mechanics. Opinions about these bugs are often controversial and can easily cause a FlameWar.

* ''VideoGame/ResidentEvil4'' had several that were BoringButPractical such as running at 1.5 times Leon's normal speed by switching to the [[ShotgunsAreJustBetter Striker]], raising it and then quickly equipping another weapon before the laser sight could activate ([[http://speeddemosarchive.com/ResidentEvil4.html useful but cautiously used]] in [[SpeedRun speedrunning]]). However, the most memorable is Ashley's abilty to [[TookALevelInBadass suplex enemies]] by [[https://www.youtube.com/watch?v=d0Tg1btDrMA whacking them with a door]]. It's also possible to open locked doors from the wrong side with the TMP equipped to bypass entire "find the key" {{Fetch Quest}}s, pressing L + R before every PressXToNotDie moment which (most of the time) makes the other button prompt appear, and being able to push Ashley through the scenery by getting her into a corner and pushing against her when she ducks (useful for keeping enemies off of her). Also, the gimmick where Ashley scolds you for looking up her skirt is literally set to trigger ''anytime'' Leon's eyes aim up in that direction - even when he's been knocked down by an enemy or his [[SugarWiki/FunnyMoments severed head rolls between her legs]].

** ''Videogame/SaintsRow1'' had, in the words of Cabel Sasser, "the world's most awesome bugs." [[https://www.youtube.com/watch?v=9l_YN-yRCVY He even composed a medley about them.]]
** ''Videogame/SaintsRow2'' has a slight glitch having to do with reloading. Usually, your nameless protagonist will reload dual [=SMGs=] by spinning them in his/her hands and keeping them at his sides. Sometimes holding down the reload button makes the game act as if you are still firing while you are in a reloading animation, meaning it looks like the guy you took out in front of you was killed by some crazy richochet.

* The ''WebVideo/SteamTrain'' playthrough of ''VideoGame/{{Skyrim}}'' relies heavily on these in order to feasibly complete such a long game in only 13 episodes (About 3 hours, give or take), with Ross using {{Speed Run}}ing tactics like using wooden plates to clip through walls, running forever in spite of the SprintMeter with torches, and climbing sheer vertical cliffs with a horse, much to Danny's sheer bemusement and delight.
--> '''Danny:''' What?! What, wha-- ''what?!'' Explain what just happened!
--> '''Ross:''' So the hitboxes in Skyrim are really finicky. The walls are like totally ''fucked''. So if you put a plate between you and the walls the game just kind of approximates where you are between the character and the plate, and for some reason since the plate's hitbox is slightly bigger and goes through the wall it glitches and just knocks you through the wall.

If a Good Bad Bug is liked ''enough'', it may become an AscendedGlitch. In some games, the bugs are a major draw for the game, which can lead to claims the work was SoBadItWasBetter if the bugs are removed. Subtropes include MinusWorld and GlitchEntity. Compare ArtificialStupidity and AIBreaker, which are more to do with how the game's processing handles (or, sometimes, can't handle) playing the game itself.

** This was such a horrific thing to be on the receiving end of, that Germany actually accused the United States of human rights violations for using the shotguns to clear trenches, citing the part of the Hague Convention which restricts the use of cruel and unnecessarily painful weapons. Note however that, in the trenches, your one other option was a trench knife that would undoubtedly cause a [[FateWorseThanDeath festering wound in a war zone.]] Compared to that, [[MercyKill the shotgun was downright humane.]]

* The setting of ''Roleplay/TheBalladOfEdgardo'' had a city called Haven. So long as a character is inside the city, their Spirit (the game's equivalent of {{mana|Meter}}) is automatically filled up to the [[{{Cap}} maximum amount they can hold]]. There's a perk availble during character creation which gives the character ''no'' maximum on the amount they can hold, but nobody had ever taken it (except for the narrator who [[ReadTheFreakingManual neglected to read the description properly]]) because it had the [[ThatOneDisadvantage crippling downside]] of locking the character out of all elemental attacks, leaving them stuck with the NonElemental "Raw Spirit". Raw Spirit, despite [[ArmorPiercingAttack not being resisted by anything]], was so weak that spending the same amount of Spirit on an elemental attack would usually still do more damage even ''if'' the target resisted it. Any character relying solely on Raw Spirit would therefore be next to useless in a fight... unless, of course, [[OneHitKill they happened to have an unlimited amount of Spirit to spend on every attack]].

** Bull with Poco's ''Da Capo!'': While the Star Power would normally cause Poco to heal teammates, it caused Bull to Burt teammates.

* Will Keith Kellogg and his brother, John Harvey Kellogg, of Battle Creek Michigan, were Seventh-Day Adventists and ran the Battle Creek Sanitarium in the late 19th century; the food, in accordance with their beliefs, was to be served bland. One day, they had to leave some wheatmeal sitting to take care of a problem at the Sanitarium and came back to find that it had gone stale. Since they were on a tight budget, they couldn't just throw it away, so they decided to roll the stale wheatmeal to make long sheets of dough. They were, however, surprised when the wheatmeal instead broke off into flakes, which they baked and served to the patients. It turned out to be a very popular choice of breakfast food, so they decided to play around with the recipe by substituting other grains for wheat. They struck gold with cornmeal and went into the breakfast cereal business, [[AndNowYouKnowTheRestOfTheStory and the rest, as they say, is history]].

* ''VideoGame/{{Paperboy}}'', the coin-op version, had a race where you tried to get through a timed game. At the end of the race, you're supposed to cross the finish line. Here's where the bug comes in: if you cross just off the edge of the finish line outside of the edge but before the hedge of the game, it switches to an inverted video version of the race you just ran. This game normally has a high score of around 50,000, but the scores for things you hit in this strange area are way out of range, making it possible to get a score of around a billion, so high it can overwrite part of the screen.

* The video game adaptation of ''Film/SpiderMan2'' allows you to fly into the stratosphere if you're hit by the train.

* ''VideoGame/{{Bayonetta}}'' has the Lt. Col. Kilgore, the slow but powerful rocket launcher tonfas that can launch a rocket with each attack. By putting the Durga in lightning mode on her feet in the first weapon set and the Kilgore on the second, use the [[SpamAttack rapid-fire kick attack]] of the Durga's lightning mode and [[RealTimeWeaponChange switch weapons]] after the animation starts. Bayonetta will continue to do the Durga's kick animation and fire the Kilgore's rockets with every kick. Mind you, the rockets are balanced to only launch one or two per attack.
** Using this glitch on the fight at the end of Chapter 2 during the fight's invulnerability phase can get you ''millions'' of halos.
* ''VideoGame/DMCDevilMayCry'' has multiple glitches that make Dante fly around the screen avoiding enemy attacks, bosses that are unwilling to attack or are just paralyzed. The fandom decided to use them [[https://www.youtube.com/watch?v=pFLUE2kdemE to have fun.]]
* In ''[[VideoGame/DragonBallZTheLegacyOfGoku Dragon Ball Z: Buu's Fury]]'', you have to get a Senzu Bean (an item that gives full health and Ki) very early in the game for a FetchQuest, but you also can eat it before you deliver it. Does this mean the game wants you to get another bean? No, it'll just take the one you don't have, which gives you [[UsefulNotes/PowersOfTwoMinusOne 255]] Senzu Beans, a number far above the item's normal {{Cap}} of three.

* The Toy Spitball Gun in ''VideoGame/DeadRising2'' really only serves as ItemCrafting parts to make the Fire Spitter weapon. Except for when you face TK's Helicopter, which takes ScratchDamage from anything except thrown weapons. Due to a programming quirk, the Toy Spitball Gun's foam balls are considered thrown weapons, meaning they'll bring it down in under a minute.

* [[https://ki-no-shirayuki.dreamwidth.org/18419.html A selection of several cases from]] ''VideoGame/ToukenRanbu'', which includes such gems as swords saying other swords' lines, swords turned into ''[[AttackOfTheFiftyFootWhatever giants]]'', an ''enemy'' being the MVP and, in a chilling moment of BreadEggsMilkSquick, a sword who has only sustained serious damage being displayed as ''[[PermanentlyMissableContent dead]]''.

** In the original, the "random" point value of the flying saucer was actually a completely predictable function of how many time the player had fired. It was worth 50 points if hit with one of the first 8 shots, 100 points if hit with shots 9 10 11 or 12, 150 points if hit with shots 13 or 14, and 300 points if hit with shot 15; then the cycle started over. A savvy player could count his shots and get 300 points each time.

* ''VideoGame/{{DmC Devil May Cry}}'' has multiple glitches that make Dante fly around the screen avoiding enemy attacks, bosses that are unwilling to attack or are just paralyzed. The fandom decided to use them [[https://www.youtube.com/watch?v=pFLUE2kdemE to have fun.]]
* In ''Anime/DragonBallZ: Buu's Fury'', you can eat a Senzu Bean before you give it to someone for a quest. Does this mean the game wants you to get another one? No, it'll just take the one you don't have, which gives you [[UsefulNotes/PowersOfTwoMinusOne 255]] Senzu Beans.

* The Toy Spitball Gun in ''VideoGame/DeadRising2'' really only serves as ItemCrafting parts to make the Fire Spitter weapon. Except for when you face TK's Helicopter which takes ScratchDamage from anything except thrown weapons. Due to a programming quirk the Toy Spitball Gun's foam balls are considered thrown weapons meaning they'll bring it down in under a minute.

* Certain more recent ''VideoGame/{{Tamagotchi}}'' models have [[http://www.pixelmood.com/tamagotchi_connection_debugging.htm a trick]] with a pencil and a screwdriver that lets you access the device's debug menu, which allows you to choose any pet you want, including those that were DummiedOut.

* Website/{{Netflix}} has a bug that can swap the description of shows. [[https://i.imgur.com/UJhdfc3.png Pictures of kids' shows with descriptions of adult shows and movies]] quickly became a meme.

* The setting of ''Roleplay/TheBalladOfEdgardo'' had a location called Haven. So long as a character is in Haven, their Spirit is automatically filled up to whatever the cap is. There's a trait a character can have which gives them ''no Spirit cap whatsoever'', but it was normally never used because it locked the character out of all elemental attacks and left them stuck with Raw Spirit only, which is extremely weak. [[DidntThinkThisThrough Unless you've got an unlimited amount of it, that is...]]

* TabletopGame/GameOfLife: Towards the end of the game's path, there is a space called "You're a grandparent!" It is entirely possible to land there without having any children.
