Infamous Video Game Glitches
Video games are complicated pieces of software, and sometimes things go wrong in spectacular fashion. A single coding mistake can turn a serious moment into comedy gold, launch players into orbit, or create digital chaos that lives on in gaming history.
Some glitches are so bad they ruin games, while others become beloved features that players actively seek out. The gaming community has a strange relationship with glitches.
We complain when they break our saves, but we also laugh at the absurdity of a giant soaring through the sky or a character’s face disappearing mid-conversation. Here is a list of infamous video game glitches that became legends in their own right.
MissingNo
Pokemon Red and Blue introduced players to a bizarre creature that wasn’t actually a Pokemon at all. MissingNo, short for ‘missing number’, appeared as an L-shaped block of scrambled pixels when players performed a specific sequence involving an old man in Viridian City and the coast of Cinnabar Island.
The glitch occurred because the game tried to load a Pokemon that didn’t exist in its data. Catching this digital anomaly gave players 128 copies of whatever item sat in their sixth inventory slot, making it incredibly useful for duplicating rare items like Master Orbs.
Nuclear Gandhi
Civilization’s peaceful leader had a dark side that emerged through an integer overflow error. Gandhi’s aggression rating was programmed so low that when India achieved democracy (which lowered aggression by 2), his value would drop below zero and wrap around to 255, the maximum possible rating.
This transformed the pacifist leader into a nuclear-weapons-obsessed warmonger. While the original developers have since stated this glitch didn’t actually exist in the first game, the legend became so iconic that later Civilization titles intentionally programmed Gandhi to favor nuclear options as a nod to the urban legend.
Corrupted Blood Incident
World of Warcraft experienced an accidental pandemic that fascinated disease researchers worldwide. A debuff from the Zul’Gurub raid was supposed to damage players briefly and stay contained within that specific area, but hunter pets could carry the disease out into populated cities.
Low-level characters died almost instantly while NPCs spread the infection without suffering its effects, becoming perfect disease vectors. The Centers for Disease Control and Prevention actually studied this event as a model for understanding human behavior during disease outbreaks, making it one of the few video game glitches to contribute to real-world epidemiology research.
Minus World
Super Mario Bros contained a glitched level that became one of gaming’s earliest urban legends. Players could access World -1 by performing a precise wall-clip maneuver at the end of World 1-2, slipping through the pipe in just the right way.
This underwater level looked identical to World 7-2 but contained one critical difference: the exit pipe sent players back to the start of the level, creating an infinite loop with no escape except death or resetting the console. The name ‘Minus World’ came from how the game displayed a blank character where the world number should be, making it appear as World -1.
Backwards Long Jump
Super Mario 64’s most famous glitch revolutionized speedrunning by breaking the game’s physics engine. Mario had no negative speed cap when performing backwards long jumps, so repeatedly jumping backward on stairs or slopes allowed him to build up ridiculous velocity.
Players who mastered this technique could phase through walls, doors, and even the magical barrier on the Endless Stairs that normally required 70 Power Stars. The glitch enabled speedrunners to beat the entire game in minutes by skipping directly to Bowser battles, and Mario’s rapid-fire ‘Ya-ya-ya-ya-yahoo!’ became a meme in the gaming community.
Giant Launch
Skyrim’s giants had a habit of sending players into low orbit with a single club swing. When giants attacked low-level characters, the game’s physics engine miscalculated the force applied, launching victims hundreds of feet into the air like human cannonballs.
Bethesda actually discovered this bug during development but found it so amusing they chose to leave it in the game intentionally. The glitch became such an iconic part of the Skyrim experience that players would deliberately pick fights with giants just to experience the launch, and it appeared in countless YouTube compilations.
Assassin’s Creed Unity Face Glitch
Ubisoft released Assassin’s Creed Unity in such a broken state that it became a cautionary tale about rushing games to market. The most disturbing bug caused character faces to fail loading properly, leaving behind floating eyes, teeth, and hair with no skin or skull.
These nightmarish visages appeared during important story cutscenes, completely destroying any sense of immersion or drama. The technical disaster was so severe that Ubisoft stopped selling the season pass and gave free games to everyone who had already purchased it, while also prompting the company to slow down its annual Assassin’s Creed release schedule.
GTA IV Swing Set
Liberty City contained an ordinary playground swing set that defied all laws of physics and common sense. When players drove vehicles into this particular swing set, the collision detection went haywire and catapulted cars across the entire city at absurd speeds.
Vehicles would spin violently, launch hundreds of feet into the air, and often explode upon landing miles away from the original impact point. The glitch turned this unassuming piece of playground equipment into one of the most entertaining features in the game, with players sharing videos of their most spectacular launches.
Heavy Rain Shaun Glitch
Heavy Rain’s emotional climax turned into an unintentional comedy when a prompt bug ruined the tension. Early in the game, players could trigger protagonist Ethan to shout his son’s name, but sometimes this prompt wouldn’t disappear properly.
During the final confrontation with the killer, this resulted in Ethan screaming ‘SHAUN!’ over and over, completely drowning out dialogue and destroying any dramatic weight the scene was supposed to carry. The relentless shouting continued even during reunion scenes and emotional moments, transforming a serious thriller into an absurdist comedy.
Pac-Man Kill Screen
The arcade classic had a hard limit that developers never expected players to reach. Level 256 caused the game to split in half, with the right side of the screen becoming a jumbled mess of corrupted graphics and symbols.
This happened because the game used a single byte to store the level number, and when it reached 256, the value overflowed and caused the display to malfunction. The glitched level was actually unbeatable since too many dots appeared on the corrupted side to collect, creating an impassable barrier that marked the absolute limit of how far anyone could progress.
Roach on the Roof
The Witcher 3’s faithful horse Roach gained internet fame for constantly defying gravity and common sense. The mare would spawn on rooftops, stand on her hind legs, walk through walls, and generally appear wherever physics shouldn’t allow.
The most iconic version showed Roach casually standing on cottage roofs, staring down at a confused Geralt below. CD Projekt Red embraced the meme so thoroughly that they released an April Fool’s video ‘explaining’ why Roach was so glitchy, and fans even created paintings commemorating the absurdity.
FIFA Giant Hands
FIFA 14 introduced a visual bug that gave every player on the field comically oversized hands. Goalkeepers suddenly had massive mitts that made saving shots almost trivial, while field players ran around with enormous flailing appendages.
The glitch spread through online matches and created hilarious screenshots that circulated across social media. FIFA games have always had their share of visual oddities, but the giant hands stood out as particularly memorable because of how ridiculous everyone looked sprinting around with hands the size of their torsos.
Donkey Kong Country 2 Castle Crush
Breaking a specific barrel in Castle Crush could literally destroy your game cartridge. This glitch caused a cascade of visual corruption, phasing characters through walls, transforming sprites into pixelated blobs, and creating kaleidoscopes of distorted colors.
The real danger came when these glitches damaged the cartridge’s hardware itself, rendering the game permanently unplayable. Players had to buy entirely new copies, making this one of the few glitches that could cause actual financial damage beyond just corrupting save files.
Sketch Glitch
Final Fantasy VI contained a dangerous exploit tied to the character Relm’s sketch ability. When the sketch command missed its target, it triggered a programming error that corrupted the game’s memory in unpredictable ways.
Savvy players figured out how to manipulate variables like which spell occupied their 28th magic slot to control the corruption and duplicate rare items. Entire strategy guides emerged devoted to mastering this glitch, though using it wrong could scramble save data and ruin hours of progress.
Floating Mammoths
Skyrim’s physics engine sometimes forgot to calculate vertical distances properly when spawning creatures. This resulted in mammoths materializing high in the sky, hovering majestically for a moment before gravity remembered to exist and sent them plummeting to earth.
Players wandering the frozen tundra would occasionally witness these massive beasts falling from the heavens like furry meteors, dying on impact and leaving behind lootable ivory. The glitch completely shattered immersion but provided some of the most unexpected and entertaining moments in the game.
Red Dead Redemption Donkey Lady
One of gaming’s most disturbing glitches transformed a human character into a nightmarish donkey-human hybrid. The creature had a human body awkwardly twisted to match a donkey’s posture, with limbs bent at impossible angles.
It would glitch across the landscape in unsettling, jerky movements that looked like something from a horror movie. The bizarre fusion of human and animal became infamous in the Red Dead Redemption community, appearing in countless ‘scariest video game moments’ compilations despite coming from a Western action game.
Swordless Link
The Legend of Zelda: Ocarina of Time let players remove Link’s iconic sword through careful manipulation. In the original version, players could save and quit during the final Ganon fight right after he knocked away the Master Sword, causing Link to respawn without his weapon.
Later versions required more complex glitches involving the ocarina system. While this seemed pointless, removing the sword actually enabled numerous other glitches like floating through the air and accessing areas that should be locked, making it an essential trick for speedrunners and glitch hunters.
Spider-Man White Cube
Marvel’s Spider-Man 2 experienced a bizarre glitch that transformed both web-slingers into tiny white cubes. Despite their geometric prison, Peter Parker and Miles Morales retained all their abilities and could still swing through New York City as miniature blocks.
Videos of small white cubes performing acrobatic aerial maneuvers and fighting crime went viral almost immediately. The glitch became such a beloved part of the game’s launch that it helped build community enthusiasm, proving that sometimes the bugs are more entertaining than the actual game.
When Glitches Become Gaming History
These digital accidents have shaped gaming culture in ways developers never intended. MissingNo remains more famous than many actual Pokemon, speedrunners build entire careers around mastering techniques like the backwards long jump, and some glitches like Skyrim’s giant launch became so beloved that removing them would disappoint fans.
Modern games still ship with bugs despite massive budgets and extensive testing, reminding us that software perfection remains an impossible goal. The most memorable glitches don’t just break games; they create stories, foster communities, and occasionally contribute to fields like epidemiology in ways nobody could have predicted.
