A speedrun is a play-through of a computer or video game, created with the intent of completing it as quickly as possible, optionally under certain conditions, mainly for the purposes of entertainment and competition. The term, a compound of the words speed and run (as in “running” through a game, referring to the playing of a game) is only used in the context of games that were not originally or primarily designed with fast completion in mind; one generally does not “speedrun” a racing game (in those cases the game's standard setting for achieving and recording fast times is called a time attack or time trial mode).[1] Speedrunning is often seen as a display of skill and is practiced competitively, as a pastime, in Internet-based communities, on which the resulting movies are released as rendered multimedia versions such as AVI files.[2]
In order to attain the highest possible quality of play in a speedrun, the author usually has to look at and think about the game differently than most casual gamers would. Generally, games' physics engines are not flawless and will allow the runner to do unexpected things that could save time. Despite their inherent differences, game engines seem to share a lot of common traits in this context, such as sufficient complexity to warrant a route to be mapped prior to the making of the run; the ability to disjunct the common sequence of events in a game and thus skip entire parts of it, or sequence breaking; and the ability to use programming errors, or glitches, to one's advantage.
Some games have been considered to be ideal specimen for fast completion purposes, and have been supported fanatically by practitioners who have built virtual communities around them, which provide (or have provided) a highly active platform for the discussion and exertion of speedrunning one or more particular games.
Overview
In its very essence, a speedrun can be described as an exceedingly skilled playthrough of a particular video game or part thereof in a competitive matter, which is usually recorded for either verifiability or simply entertainment purposes. Verifiability may be described as stemming from the necessity to provide evidence that one's playthrough went by the typical or game-specific speedrunning rules and thus counts as a valid attempt to beat the record. Entertainment has traditionally been the reason for the creation of speedruns, as it stems from enthusiasts who began comparing each others' playing skills via movies exchanged over the Internet.
The bare requirements for the creation of a speedrun pertain to one's ability to play the game; skillful playing is crucial, along with good knowledge of the game, as a player must know exactly what to expect during an intensive “run” through the game, and also realize the most optimal method to do so. Lastly, the making of a speedrun requires perseverance, as it relies heavily on luck in addition to skill (the latter has been described as “that which makes it possible”, while the former is seen as “that which makes it happen”), and thus requires persistence during the course of action, regardless of difficulties, obstacles, or discouragement.[3] Despite this, speedrunners will usually cease their attempt in case a mistake is made, depending on how it could affect the run's outcome; breaking previously set records is the goal for many runners, and one must keep in mind that even the slightest mistake could null one's chances of doing so, especially if the holder of the current record did not make that same mistake. For example, in Quake speedrunning, mistakes as small as missing a single shot could be reason enough to stop the current attempt and try again, as years of intensive competition have brought about very high quality standards; there is a lower threshold for less popular games, however. Runners practice intensively to attain the ability to play at such a high level of skill for usually months, but sometimes even up to years (especially in the case of constantly updated speedruns or those for which entire Internet communities have been set up, such as Quake). For example, Mike “TSA” Damiani, the author of a speedrun for The Legend of Zelda: Ocarina of Time wrote this about his record achievement:[4]
[...] back in the day, I played Ocarina of Time more times than I can count. I was quoted as saying I played this game for 10,000+ hours, when in actuality, it's probably closer to 25,000 hours. I mean I played this game non-stop for over two years. It's not even a matter of ability anymore when it comes to Ocarina of Time. It's just part of my nature when it comes to this game, it's just so natural. I'm sure there are others out there who share this same experience with other games.
—Mike “TSA” Damiani
Depending on the popularity of the game, it may be so that a generous amount of practice is required in order to attain such a quality of play that one may attempt to beat the record.
Classification
There are two major genres in speedrunning: “unassisted” or “regular” speedruns, and “tool-assisted” speedruns.[5] Unassisted speedruns are done in real-time using only whatever features there were in the actual game on the original hardware, while tool-assisted speedruns also use features found outside the game in order to create the movie, such as the “save state” feature found in emulators (which is called re-recording in this context).
Among the subgenres, there are two major categories: “any%”, and maximum or “100%” speedruns. Any% runs involve the player aiming to complete the game as quickly as possible, skipping as much of the game as needed, while 100% runs require that as much of the game is played as possible, such as killing all enemies in the game, collecting every item available, or completing all goals or missions. Some runs fall into the “low-percentage” or “low%” category (sometimes also called “minimalist”), where the fastest time is attempted while collecting only the bare minimum amount of items, power-ups or abilities required for completion.[6] These are usually slower than the any% runs due to extra time spent killing enemies with lesser abilities or actively avoiding items.
The creation of a speedrun is usually done by one person, and sometimes by a whole team.[7] By one person, it can be done in one play session (a single-segment speedrun) or multiple (a multi-segment or segmented speedrun; usually replaced by the number of segments: “in ten segments”). Segmented speedruns are done by defining what a game's divisions are in order to run them separately, in multiple sessions (usually separated by save points). This allows for a higher level of perfection because the entire game does not need to be run all at once; runners can redo small parts of a game as many times as they need to until they are satisfied with the result; it's for this reason that segmented speedruns are exclusively faster than their single-segment counterparts. It is normal, however, that the individual parts are done in order of appearance in the game, since the actions taken in one segment would affect later segments; such as the weapons that one obtains in a first-person shooter or the experience points that one attains in a role-playing game.
Rationale
As was previously noted, speedruns stem from the closely related act of sequence breaking, and were traditionally made mostly for reasons of entertainment and competition, initiated by enthusiasts from online Internet-based communities who wanted to compare each others' skills. This is still the incomparably dominant reason for the creation of speedruns today, although the competitive aspect of it has become increasingly important, especially since efforts to help people publish their speedruns started being exerted by the Speed Demos Archive team. When tool-assisted speedrunning was introduced, reasons for the making of a speedrun that pertain only to this special category of runs were invented (in addition to the usual ones): they argued that the runs they were producing could be considered a form of art, claiming that they significantly hold “creativity, variability, surprising outcomes, and speed”, which makes them “beautiful to watch”.[8] They also function as proof-of-concept demos for the making of unassisted speedruns or as visual walkthroughs. The tool-assistance community also further defined exactly what entertainment in a speedrun should imply: it should be interesting (as in not slow, boring or repetitive), it must be surprising (the runner must do the unexpected in order to do so), and it must be skillful (the player must be able to handle awkward situations efficiently and creatively).[8] Due to the fact a tool-assisted speedrun cannot be expected not to strictly try to adhere to these requirements, as it is easily possible to redo segments of a run in case it is determined that it is not entertaining enough, it is also stressed that they do not necessarily pertain to unassisted runs; despite that, unassisted runs usually do conform to them quite naturally, as a high level of playing skill may ensure this.
History
Doom developed what might have been the first online speedrunning fanbase, emerging in 1994 around newsgroups, FTPs and websites that collected demos (see Doom speedrunning). Speedrunning entered mainstream with the famous Quake done Quick demo for Quake created by the eponymous group. QdQ also produced Quake done Quicker, which was later made obsolete by Quake done Quick with a Vengeance, and Scourge done Slick, movies which in addition to top-notch speedrunning skills featured humorous plot and camerawork, making QdQ one of the pioneers of the machinima community.
It could be argued that all of the Metroid games were among the first to have major speedrun challenges. They have built-in rewards for speed in the form of earning better endings for beating the game faster. However, even earlier games like Super Mario Bros. would reward the player with points for completing levels quickly.
Common techniques
In order to attain the fastest possible time in a speedrun, the author usually has to look at and think about the game differently than most casual gamers would. Generally, games' physics engines are not flawless and will allow the runner to do unexpected things that could save time. Despite their inherent differences, game engines seem to share a lot of common traits in this context.
Route planning
Route planning sheet for the
Bomb Man stage in Joel Yliluoma's
Rockman tool-assisted speedrun
An essential part of speedrunning is to find the most optimal feasible route that leads to the completion of the game (or segment thereof). A route, in the context of speedrunning, is a course of action with which to get from one point in the game to another. The need for determining such a route stems from the complexity of the separate areas in which the gameplay takes place. For example, a level designed as a maze will require extensive planning to ensure that the best method for passing the area is found. Even in games in which the levels seem fairly straightforward, it is often required that a route is taken that ensures some kind of advantage; such as a certain degree of safety or beneficial items that can be found along the way, as an “optimal” route is designed not only to be fast, but also to take into account the effect it might have on other resources that might affect later levels. The need for the construction of a route depends on the structure of a level.[9]
In highly non-linearly structured games there is often no obvious choice, as there might be many choices that the player can choose from that require extensive research to appraise. For example, the shortest possible route might contain so many obstacles that it is virtually impossible to use; it is therefore often necessary to find a compromise between ease and distance. Depending on how the player's skill improves, faster but increasingly difficult routes may be chosen; record times for this reason mostly utilize the most highly yielding route, depending on the popularity of the game — it is nearly impossible that a fair degree of competition will not force players to get the advantage by taking the routes that have the most potential. Contrary to strictly linear levels which can only be finished using one predetermined route, there are games in which levels leave a lot of room for creativity in its playthrough.
While route planning may seem like simply the planning out of a route that allows one to efficiently finish a level, it also pertains to other aspects of a game that incorporate choice. For example, one may find that when allowed to choose between several starting conditions, such as the choice to play the game with a certain type of character, will also greatly affect the feasibility of a playthrough. In the game Hexen, for example, we are allowed to choose between three different “classes” of characters, one being a knight (who is agile and strong), a mage (who is slow, yet has powerful magic abilities) and a cleric (a versatile combination of both); speedrunner “Cacodemon Leader” found out that the cleric was the most feasible character to play the game with, as it isn't as slow as the mage in the beginning, yet does gain a significant usability boost near the end of the game (which the knight does not), thus yielding the best outcome in the end.[10] Runners would describe this choice as obvious, seen as how it simply allows the runner to finish the game more efficiently. And yet, it may not be optimal if the goal of a speedrun were to change. After all, we see that the knight is a very strong character in the beginning of the game; if the speedrun's goal were to finish only the first cluster of levels, then the knight, who is able to rush through the first few levels with relative ease, would likely be the most useful character; if the speedrun's goal were to finish using only the first weapon in the game, the mage would be the strongest, as the mage's first weapon continues to be viable even during later levels. A separate rationale, and a very important aspect of this form of route planning, is that some cases may be described as tiers as well; using Hexen as an example again, we find that some runners might want to do a run on the game using the knight or mage anyway, even if this ensures a slower playthrough than when the cleric is used, simply in order to set a fastest time using a different character choice as prerequisite. Such runs are then in a separate category than the “main” run which would still pertain to the cleric. In essence, this is the same as the difference between other differences in classification, such as 100% and any% runs. The possibility to run through a game faster by using a superior strategy that spans across the game in its entirety depends on its linearity. The more linear the game is, the less able a player will be to alter the large-scale route of play, as there simply will not be many choices to take or affect.
The amount of planning that can go in both the level sequence and the actual gameplay may vary a lot and be disproportionate; one might spend a lot of time planning out the route of an individual level while the general route in the game is relatively straightforward, for example. On the contrary, one may also find that the route of an entire game is much more important than the planning out of individual levels, as would be the case with many racing games that incorporate a certain degree of strategy, Gran Turismo, a racing game in which the player is able to buy different cars and upgrades, being an example; the speed at which one can play this game depends almost entirely on the choices made outside of racing, as a player will have to plan out which of the in-game racing tournaments he will attend to be able to get to the point where he can attempt the final one as quickly as possible.
While this type of strategic route planning is essential, there are other (usually highly linear) games in which it is useless. In that case, runners are often presented with extensive methods for optimizing routes for individual levels or segments of the game. A good example is Quake, in which we can find many good examples of the effect that route planning can have on the outcome of a speedrun, as even years after the initial versions of its speedrun routes there are still additional shortcuts being discovered that can speed up one's progress. One notable example of a level which has undergone a lot of route changes in this game is E4M3 [3] (The Elder God Shrine).[11] Originally, the route for this map was very long and involved going through the graveyard in addition to many other things. After the release of the first Quake done Quick video, in which this route was recorded as a 1:21 run by Yonatan Donner, it was found out that a large part of this route could be skipped by using a slope jump in the starting room, leading to Donner improving his run to 0:57.[12] This was the basic foundation of the map's route, which is still being used today: do the slope jump, get the silver key, run back to the start room, jump to the other side, get the gold key, and exit. A variety of new shortcuts were found since then, constantly updating the optimal route. Following Donner's record, “DooMfienD” used an in-flight grenade jump from the back of a Fiend rather than one from balcony to balcony in order to get to the other side of the start room. He also added a grenade jump at the silver key and got 0:55 for Quake done Quicker.[13] Markus Taipale later replaced this with a bunny hop.[14] Evan Wagner ran 0:54 by adding a grenade jump from the Knights near the gold key and an additional boost in a long hallway. These additional grenade jumps became possible due to more efficient health usage attained by picking up the second large health upgrade when returning at the starting point rather than when starting. Ilkka Kurkela added bunny hops to get 0:50. The grenade jump at the silver key went through a few revisions (being replaced by a double grenade jump or a quad boost) but was eventually reverted to DooMfienD's original method because the health was needed for a much more important trick devised by Markus Taipale: a Fiend boost after the start, and a Quad Damage grenade jump at the gold key that carries the player at full speed nearly all the way to the exit. Combining all of these tricks, Markus was able to record 0:40 for Quake done Quick with a Vengeance, a run which he later improved to 0:37.[15]
Even so, this route was still not optimal, as proved by Peter Horvath, who added a grenade jump from a Spawn in the lava near the silver key — labelled by the team as a “never-thought-of-before trick” — which gave him the currently fastest time of 0:33.[16] While this route is currently believed to be optimal, Horvath himself admits that it is still possible to improve on his play.[17]
Sequence breaking
Aside from route planning, there are multiple other commonly utilized techniques that are separate from the typical prerequisite of excelling playing quality. With the previous paragraph in mind, it is implied that the best routes rarely rely upon the paths and progressions that were designated by the developers; skilled players will usually discover ways to finish parts of the game in a different order than was intended, and they consequentially often find ways to skip parts of a game entirely. Using these shortcuts, which are closely tied to route planning in that it builds upon it by providing additional strategic depth, is called “sequence breaking”. Sequence breaks are often possible because their existence has been overlooked by the developers, or via a glitch (see section “Glitches” for an explanation). Usually, only shortcuts that are believed to not be part of the gameplay as the designers had intended it are considered to conform to the definition.

Bowser's sub before the game,
Super Mario 64, is supposed to allow the possibility. This allows the runner to skip a total of 54 stars and save around 50 minutes of time; see a video of this trick being performed below.
The first documented action in a video game to be called a sequence break occurred in the Nintendo GameCube game Metroid Prime. It was called “Gravity Suit and Ice Beam before Thardus”; using the since then common “x before y” notation in the nomenclature of sequence breaking (as the disjunction of sequences is the essence of such events). Thardus was designed to be a mandatory boss before the Gravity Suit and Ice Beam could be obtained, hence the novelty of bypassing the boss while still obtaining the items. This was first achieved by Steven Banks on January 18, 2003, after the possibility of such an act was suggested by “kip”, an online persona and important Metroid speedrunner whose real name is unknown.[18] Banks posted his findings about the act being possible on the Metroid Prime message board on GameFAQs in a thread which attracted a number of interested gamers. The gamers quickly became a separate community and strove to accomplish more and better feats in the game. It is currently assumed that the term, as used in this context, was first coined by a person known online as “SolrFlare” in this thread on February 5, 2003.[19] Thus, the term remains most often applied to the Metroid Prime series of games, as opposed even to other games in the Metroid series or games in general (in other contexts, it is also simply called a shortcut).[20] Sequence breaking has become an integral part of speedrunning and has been applied to many other games besides those from the Metroid series. It is always considered a possibility when planning a speedrun.
Sequence breaking methods are usually discovered after new techniques have been found. A runner has to adapt his strategy to make the most of such new techniques, which may also create opportunities to skip parts of the game, if the techniques are beyond typical gameplay. A well-known trick for sequence breaking in first-person shooters is the so called “rocket jump”, which consists of intentionally jumping over a mine or shrapnel while it is exploding, or while shooting the ground with a rocket launcher. The propulsion from the explosion allows the player to jump higher than normal, reaching nearby but otherwise unreachable places. Obviously, the player incurs significant damage from the explosion; one usually has access to a limited number of rocket jumps in one level before a next one would cause the character to die. For that reason, rocket jumps require extra planning to make the greatest usage of the health that is available in the level, both directly (through health packs that are found on route, for example), or indirectly (such as by taking a detour to get more health if the resulting rocket jump capabilities will make up for the time lost to obtain the health).
The “
trigger” object on the foreground (highlighted in red) is bypassed in a creative way, allowing an unreachable key (not pictured) to be grabbed; if the player were to touch the trigger object, the key would be transported out of reach.
In another example (again, from the Quake done Quick speedruns), the runner jumps to an otherwise unreachable key (used to open up a door that leads to the exit) by deliberately getting hit by a gib that was fired at him by a nearby zombie at the beginning of E3M2 [4] (Vaults of Zin).[21] By getting hit by the gib, the runner gains additional upwards momentum, which, if done right, can carry one over the trigger that would activate a QuakeC script which would move the key out of reach when touched. This technique requires precise timing and practice, and ultimately also a lot of luck.[22] Since the level is centered on finding an alternative way to reach the key, the sequence breaking permits the runner to skip almost the entire level.
One famous example of sequence breaking is a series of glitches which allow Super Mario 64 to be completed after collecting only 16 stars (as opposed to 70, which is the game-legitimate minimum); the game can be completed in less than twenty minutes by doing so.[23] The tool-assisted run of the game utilizes a similar series of glitches to complete the game after collecting only 1 star, allowing a time of under 7 minutes to be achieved.[24]
Glitches
Sometimes a glitch will allow for an interesting speedrunning opportunity. When running a game, it is sometimes possible to use the physics of the game to do things that would normally seem out of ordinary gameplay possibilities.
The classic example, which has been possible since the early years of video games, and can be found in modern game engines even today, is being able to walk through an enemy due to a simplistic “close approach” collision detection; since games usually don't do pixel-precise collision checks, it is sometimes possible to touch and even go partially inside the enemies without getting hurt. This is due to the so-called “hit boxes”, which detect whether an object is inside another and are often smaller than the sprites or models of enemies themselves. Additionally, if one is moving very fast, it's sometimes possible to go through objects because the game does not render a frame in which one is inside the object. Combined with the close approach collision abuse, the speed may not even need to be very high. For example, if a hit box a is moving diagonally upwards and to the right at 4 pixels per frame towards hit box b, it could pass through an area of 4×4 pixels.
Similarly, by various means (such as pushing into corners in strange ways or getting pushed by an enemy), one may sometimes get inside the floor, walls, or ceiling. While it might be that the player just gets stuck and ruins his game because he can now no longer continue, it might also allow the usage of new routes that did not exist before. For example, one might be able to jump out of the clipping zone very easily, allowing the complete passing through it. Because of close approach collision detection being so simple to most games, it is made to look accurate by “ejecting” the object if it ends up partially inside a wall or other impassable zone. It also ensures the character can't get stuck inside a wall because of simple programming. Visually, this appears as scrolling: the game automatically moves the object that's inside the wall, usually horizontally and to the right, until it finds a place where it can exit the wall. When this happens, sometimes the game will even push the player further into the wall. This trick, called “zipping”, can be used to take radical shortcuts in games, but are usually too difficult to pull off consistently in most unassisted speedruns.
Another commonly used technique is the usage of temporary invulnerability given to the player by the game, usually straight after getting hit by an enemy. Most games visualize this invulnerability by making the player character flicker. This is to prevent the player from immediately getting hit again, but can sometimes also protect him from instant death hazards, such as deadly spikes or lava. It can also be used to pass through monsters that would otherwise take more time to destroy, or to pass through other nearby monsters that would do more damage. Temporary invulnerability is also usually given to the player during a cutscene that cannot be interrupted, such as a story dialogue or the animation for finishing a level. If the player touches something lethal during this state of game, the game may very well ignore it and let him continue like nothing at all has happened. A good example is Tenchu, in which all cutscenes happen in the same environment as the gameplay. Since the state of the environment is carried over to the cutscene, it is possible to, for example, place a mine on the path of one of the acting characters; the character will walk over it, trigger it, get set on fire, and yet continue partaking in the scene as if nothing happened.
Many polished and acclaimed speedruns are filled with glitch abuse, but the usage of several inconspicuous glitches may be left unnoticed by casual gamers.
Tool assistance
A tool-assisted speedrun (commonly abbreviated TAS) is a speedrun movie produced with the use of tools such as slow motion and re-recording. The basic premise of these runs is that a “tool” (like an emulator that provides the author with slow motion and re-recording functionality) is used in order to overcome human limitations such as skill and reflex.[8] These tools are used to create theoretically “perfect” runs.
Tool-assisted speedruns are mostly done with emulators for old console systems. Emulators that currently feature the tools necessary to create these tool-assisted speedruns include the Nintendo emulators Famtasia, FCE Ultra [5], Nintendulator and VirtuaNES, the Super Nintendo emulators Snes9x [6] and ZSNES [7], the Genesis emulator Gens [8], the Game Boy Advance emulator Visual Boy Advance [9], and the Nintendo 64 emulator Mupen64 [10].
The tool-assisted speedruns try to avoid comparisons to the unassisted runs, as this would be unfair to the players. In unassisted runs, it would be unacceptable to use emulator's save-state features to take a shorter but more dangerous path, saving the game when passing an obstacle. Tool-assisted speedruns also abuse glitches that are sometimes impossible to replicate in unassisted play, causing more separation between the categories.
Ideally, tool-assisted speedruns are not created to show off one's playing skills, but rather to show off all kinds of techniques that are theoretically possible in the game but impossible to do in practice, and to try and establish an “optimal” playthrough of a game. Because of this, tool-assisted runs discern themselves by pushing the gameplay to the physical limits of the game's engine. This is extensively demonstrated in the Mega Man [11] and Rygar [12] runs.
While speed is desired in these runs, the focus is on entertainment. For example, there is a famous tool-assisted speedrun of Super Mario Bros. 3 by “もりもと” (“Morimoto”) that finishes the game in approximately 11 minutes; the fun is in the breathtaking speed and overall unfathomable method at which the game is being played, not the presumed skills of the runner.[13] The video has since been rendered obsolete by a faster tool-assisted speedrun, but this video is still the most famous example of its kind.
The controversy revolves around the similarity between the finished products. Websites exist dedicated to each side in the hopes that the movies will be considered separate. However, some individuals have allegedly tried to submit tool-assisted speedruns as unassisted speedruns. Without careful analysis, it is sometimes hard to tell the difference between the two, and this has been said to undermine the effort put into unassisted speedruns.
Tool-assisted speedruns usually extensively abuse glitches, such as this zipping trick, which makes travelling through walls possible. Contrary to how it may seem, the game (
Mega Man) was not modified for the production of this image; the
input used is fully “legal” and accepted by the game.
Notable games for speedrunning
-
Traditionally, speedruns have been performed by members of online communities about games in general, usually through discussion forums, using strategies devised by members of such forums. When the activity became popular enough to acede subculture, the first sites dedicated to speedrunning started appearing — usually specializing in just one or a few games. Some of these sites have sustained activity for a long time, sometimes even up to today, due to the large potential its games have for speedrunning.
Only the most noteworthy games that have been proven to be ideal for speedrunning purposes have been listed here with a short description on the histories of the communities that surround it. There are other games which have been fought over actively by many runners but don't have large or active collaboration websites dedicated to it (and haven't in the past); information on these games may be found in Notable games for speedrunning.

Quake is arguably the only game to rival Doom as the most popular game to speedrun ever.[25] People first started recording demos of Quake playthroughs when it was released in June 1996 and sharing them with others on the demos/e directory in Cdrom.com's Quake file hierarchy. There were two distinct kinds of demos: those in which the player killed all monsters and found all secrets on the map (called 100% demos) and those in which the player ignored these goals in order to finish the level as fast as possible (called runs). All levels were, at that time, recorded solely on the “Nightmare” difficulty level, the highest in the game.
In April 1997, Nolan “Radix” Pflug first started the Nightmare Speed Demos web site to keep track of the fastest demos. The first Quake done Quick [14] project was finalized in June that same year. Quake done Quick, unlike the conventional record demos, featured a full playthrough of the game, carrying over one level's finishing statistics to the next. The project ended up finishing the entire game on Nightmare difficulty in 0:19:49 [15]; an astonishment at that time. The run was “recammed”, reconstructed so that it could be also viewed from a third-person perspective, which gained it its machinima status and arguably had made it more comprehensible and entertaining for a wider audience. It received widespread attention from gaming magazines, being distributed with free CDs that usually came with them. This popularized speedrunning for a much larger audience than before and attracted many newcomers. Not all of those newcomers agreed with the old-timers' dogma that runs should be made on the hardest possible skill level. Thus, in August 1997 Muad'Dib's Quake Page came to be, run by Gunnar “Muad'Dib” Andre Mo and specializing in “Easy” difficulty runs. One month after that, the famous Quake done Quick movie was superseded by a new movie called Quake done Quicker, on September 14, 1997, which improved the game's fastest playthrough time to 0:16:35.[16]
In April 1998, Nolan and Gunnar merged their pages, thus creating Speed Demos Archive, which today is still the central repository for Quake speed demos of any kind. Ever since its creation, a large variety of tricks have been discovered in the Quake physics, which kept players interested even up to today, almost ten years after Quake's release. Subsequently, Quake done Quick with a Vengeance was released on September 13, 2000, which featured a complete run through Quake in the hugely improved time of 0:12:23.[17].
As of March 2006, Speed Demos Archive contains a total amount of 8481 demos (on both official and custom maps), accounting for a total time of 253 hours, 44 minutes and 39 seconds.[26] The fastest any% single-segment completion times that have been recorded thus far, as of June 10, 2006, are 0:13:46 [18] for the easy difficulty run and 0:19:50 [19] for the nightmare difficulty run, both by long-time Quake runner Connor Fitzgerald. The 100% single-segment completion times are 0:46:02 [20] for the easy difficulty run and 1:09:33 [21] for the nightmare difficulty run, by respectively Marlo Galinski and Justin Fleck.[27] Additionally, a new Quake done Quick movie with the working title Quake done Quick with a Vengeance Part II is in the making. The improvements that have been made thus far would result in a time of 0:11:32 for the entire game, an improvement of 51 seconds.[28]

Doom
December 1993 saw the release of id Software's Doom. Among some of its major features, like at that time unparallelled graphics, LAN- and Internet-based multiplayer support, and user modification possibilities, it also gave the players the ability to record demo files of their playthrough. This particular feature was first picked up by Christina “Strunoph” Norman in January 1994 when she launched the LMP Hall of Fame website.
This site was, however, quickly made obsolete by the DOOM Honorific Titles, launched in May 1994 by Frank Stajano, which introduced the first serious competition between players.[22] This site would create the basis for all DOOM demosites that would follow. The DHT were designed around a notion of earning titles by successfully recording a particular type of demo on pre-determined maps in the IWADs. These 'exams' became very popular as the player had to earn each title by sending in a demo of the feat to one of the site's judges to justify his application. Doom II was released in October 1994, and the DHT conformed to the new additions as well as the new Doom version releases. At the height of its popularity, the DHT had many different categories and playing styles. For example, playing with only the fists and pistol while killing all monsters on a map became known as Tyson mode, named after the heavyweight boxer Mike Tyson. Pacifist-mode was playing without intentionally harming any monsters. Each category had easy, medium, and hard difficulty maps for players to get randomly chosen for. Many legends in the Doom speedrunning scene started out in the DHT, including George Bell (Tyson), Steffen Udluft (Pacifist), Kai-Uwe “Gazelle” Humpert, Frank “Jesus” Siebers (Nightmare), Benjamin "Cowboy" Lauterbach (Reality), and Yonatan Donner. However, the DHT always had trouble retaining a permanent Internet location. This, combined with the changing rules and the diminished importance of most of the titles, made public interest wane as the years rolled on.
In November 1994, the Doom speedrunning scene, in the form of the COMPET-N website, took off.[23] Its creator, Simon Widlake, intended the site to be a record scoreboard for a variety of Doom-related achievements, but unlike its predecessors, they all centered around one key idea: speed. Players were required to run through Doom's levels as fast as humanly possible in order to attain a spot on the constantly-updated COMPET-N scoreboards which eventually made Doom one of the most popular games for speedrunning.[25]
Like the DOOM Honorific Titles, this site experienced multiple location changes over time; it was even at Cdrom.com for a while before Istvan Pataki took over as maintainer and moved the site to the now defunct FTP server ftp.sch.bme.hu. From there on, since early 1998, it was in the hands of Adam Hegyi, who has been the maintainer ever since. It is currently located at Doom2.net.[24]
As of March 2006, COMPET-N contains a total amount of 6072 demos (on both official and custom maps), accounting for a total time of 462 hours, 8 minutes and 20 seconds.[29]

Metroid series
Metroid Prime completion screen after Nolan “Radix” Pflug's famous 100% speedrun, now made obsolete by an even faster version
Released in August 1986, Metroid was the first game to introduce special rewards for fast completion times. Featuring highly non-linear gameplay, it was possible for a player to extensively search for faster routes towards the end of the game. This has been researched thoroughly since the game was created, and it has since been concluded that only a few items are necessary to complete the game.
The release of Super Metroid in 1994 greatly increased the quality of Metroid speedrunning. It featured a physics system that allowed for a wide array of skills for mobility, like wall jumping or the Shinespark, allowing players to skip over large areas of the game, or play through the game in different manners based on how well they could perform these tricks in contextual situations. Additionally, it had the same non-linear gameplay the fans had come to expect from the series. Due to the way the game is laid out, several different run types or tiers that incorporate different completion percentages have been done (see section “Glossary”). The most popular type is the maximum or 100% run, in which as many items as possible are obtained. Besides it, speedrunners also attempt any% runs, which focus solely on finishing the game as fast as possible with no other prerequisites.[25] One such speed run, created by Brian Hodge, was completed in 0:42 minutes. This has since been recognized by Twin Galaxies as the current any% world record. [26]
The tool-assisted community has also made a run in which as few items as possible are obtained, accounting for a completion percentage of 14%. Even though much fewer items are taken in this run, it's slower than the route in the any% run because of how long it takes to kill Ridley and Mother Brain with only the Ice Beam, despite it being unnecessary for completion (as the Speed Booster may also be used to get past the first Zebetite as well).[27]
Following Super Metroid there was an 8 year gap during which no new Metroid games were released. During this time, the first games in the series were played intensively by dedicated gamers, and many tricks were discovered that allowed players to achieve incredibly short completion times. As the Internet became more available to the general public, runners began to find each other online. Groups of players started collaborating on message boards and sent tricks back and forth to one another, in what became a community based on playing the games speedily.
The first Metroid community that was created for the purpose of fast completion was Metroid Prime Discoveries, created and led by Jean-Sebastien “Zell” Dubois.[28] Rather than being a site that focused on speedrunning, it was dedicated to documenting the possibilities of sequence breaking in the game Metroid Prime. When the interest arose to begin the documentation of other games in the series, however, the new site Metroid 2002 was created by Nathan Jahnke in August 2003.[29] Initially, the only incentive was to document the two Metroid games released in 2002 — Metroid Prime and Metroid Fusion — but this changed when Nathan was asked to take all content of Metroid Online, another site that had been developed at that time and contained sequence breaking documentation, a message board, and a 1% Metroid Fusion run, and relaunch Metroid 2002 as “the one resource for Metroid Prime sequence breaking info.” This relaunch happened less than two weeks later than the proposition and came to be in November.[30] Ever since, it has been the central repository for everything related to speedrunning the Metroid series.
It was also in November 2003 that Metroid speedrunning reached its peak, after Nolan Pflug released his 100% run of Metroid Prime, in which he finished the entire game in 1:37.[31] Since it was featured in the games section of Slashdot, it gained widespread attention.[30] Publications in numerous different languages ran stories on the run, and topics about the run were made on gaming message boards around the world. The first segment of his run was being downloaded over five thousand times a day at the peak of its popularity.[32] The Metroid 2002 IRC channel was flooded with people who had heard about the run and wanted to know more about it, quickly dwarfing the original population, and its message board saw its member count double in size the month following the run's release. As a result of the popularity of this run, it was decided that in order to best serve the growing bandwidth consumption, Metroid 2002 would have to merge its array of videos with Speed Demos Archive, which was at that time being provided nearly limitless server capacity for their runs on the Internet Archive.
As of June 2007, the best completion time and the best 100% time was reduced to 0:42 by Max "Jesus" Kiefer, demolishing Nolan's hugely popular run.[31]
Notable speedrun records
As speedrunning is typically the pastime of Internet communities, most of the produced runs do not get media coverage, even if the phenomenon itself does. Despite this, several runs have been reported on outside of their niche.

On August 28, 2005, speedrunner Cody Miller reported that he had finished making a run of Halo 2 on the “Legendary” difficulty level, the hardest in the game, without dying, in 3 hours and 28 minutes.[33] He states that he initially got the idea from a bounty of $250 offered by the video game record database Twin Galaxies,[34] which also outlined the rules to which the run had to conform.[35] Although runs confirmed by Twin Galaxies are not usually verifiable by independent parties, as the site upholds a policy of not publishing videos of the recordings they receive in order to protect the record holder's strategies, Miller decided to explain the contents of his run in detail and offer the video for download on the Internet Archive.[32] In 2006, this led to his efforts being recognized by Guinness World Records — his record was published in the 2007 edition of the book, and he became the first speedrunner to appear in it. The story was noticed by Bungie Studios,[36] the developers of the Halo series, and was picked up by several major news sites, including CNET,[37] GameSpot,[38] Joystiq,[39] and Yahoo!.[40]
Glossary
In the context of speedrunning, many common terms, usually neologisms, have been created. These terms are necessary to understand most general discussions about the phenomenon. This list covers the most ubiquitous terminology. Note that some words may have a different typical meaning outside of the lexicon of speedrunning; for example, frame applies to movies as well as to video games, but only the latter has relevance in this case. Also, there are more specific terms in the context of tool-assisted speedrunning which can be found in its corresponding article and paragraph (see section “Glossary” in Tool-assisted speedrun).
- Frame
- One of the still images composing the animation of a video game. Most gaming systems update the screen (approximately) 50 (PAL) or 60 (NTSC) times per second.[41] Every one of such updates is called a frame — even if only every second or third frame is rendered, as seen on some systems, notwithstanding lag (see below). Almost all console systems check the input (which buttons are pressed on the controller) once per frame, which is therefore the highest possible resolution of input.[42] For example, if firing a weapon by means of pressing a button (or otherwise providing one particular type of input) costs one frame of input in a game that runs at 60 frames per second, it is possible to fire that weapon 30 times per second. (Per the Nyquist–Shannon sampling theorem, at least one frame of not giving any input is required after each pressing of the button to prevent the system from seeing the input as one long depressed state as opposed to many individual depressions. If two buttons can be used to perform the same action, they may be used subsequently to perform the action without pausing.)[43] Maximum input is usually only performed by tool-assisted speedrunners.
- Glitch
- An unintentional feature in a game ― usually considered erroneous. Many games contain glitches, some very small and hardly notable, but others very significant. Glitches are the result of sloppy programming, whether accidental or intentional. Because many console games are ran on rather slow machines, there is usually a limited environment for performing calculations. “Perfect” programming (such as pixel-perfect collision checks) would often be too slow to be practical. As a result, programming “shortcuts” have to be taken for some routines (such as checking whether a character is entering an impassable area, and other ubiquitous or otherwise often executed code) in order to ensure that the hardware would have sufficient processing power to execute it. Glitches are used (or, arguably, “abused”) by speedrunners in order to progress through the game faster, skip parts of the game, or change the course of the gameplay altogether. See section “Glitches” for further information.
- Lag
- The effect experienced when the game runs slower than normal due to there being too many instructions for the CPU to calculate in the time of one frame. Thus, the CPU will spread the calculations over multiple frames. Because it cannot show the results of the calculations when expected, there will be identically rendered frames while it is working. Often, during lag, the game will ignore the player's input until the calculations are performed. There might also appear graphical anomalies, such as head-up displays appearing in the wrong place. Note that lag often refers to delays experienced in computing communications, such as during online gaming; this particular definition is of little relevance to speedrunning as very few speedruns are played by multiple people simultaneously via an internet connection.
- Low-percentage, low%, minimalist
- Type of speedrun in which the fastest time is attempted while collecting only the bare minimum amount of items, power-ups or abilities required for completion. These runs are slower than their “any%” counterparts due to the extra time spent killing enemies while having lesser in-game abilities or actively avoiding items.[6] Speedruns of the Metroid series are particularly good examples, as the open nature of the games, coupled with the ability to use programming errors, allows for extensive route planning to yield very low completion opportunities.
- Maximum, 100%
- Type of speedrun in which as much of the game is played as possible, such as killing all enemies in the game or collecting every item available. These runs are slower than their “any%” counterparts due to the taking of actions and going to places in the game which are not necessary for the game's completion.
- Any%
- Speedrun which involves the player aiming to complete the game as quickly as possible, skipping as much of the game as needed (notwithstanding tiers).[6] This is the original, conventional, and most ubiquitous type of run.
- Multi-segment
- A speedrun performed in multiple play sessions (or “segments”). In formal descriptions, such runs are usually accompanied by the number of segments, such as “in ten segments”. Segmented speedruns are done by defining what a game's divisions are in order to run them separately, in multiple sessions (usually separated by save points). This allows for a higher level of perfection because the entire game does not need to be run all at once; runners can redo small parts of a game as many times as they need to until they are satisfied with the result; it's for this reason that segmented speedruns are exclusively faster than their single-segment counterparts. It is normal, however, that the individual parts are done in order of appearance in the game, since the actions taken in one segment would affect later segments; such as the weapons that one obtains in a first-person shooter or the experience points that one attains in a role-playing game.
- Run
- A short and informal term for speedrun. It is often used instead of the term “speedrun” on online discussion forums. Similarly, tool-assisted speedruns are commonly abbreviated TAS (see section “Glossary” in Tool-assisted speedrun).
- Single-segment
- A speedrun performed in one continuous play session. Single-segment speedruns are often, if not always, slower than multi-segment speedruns, due to the fact a runner does not have the ability to stop the game periodically to redo (and thus optimize) parts that he has already played.
- Tier
- A particular intention or set of rules with which to record a speedrun, such as playing with different characters or taking a certain route. For example, if a route is found that allows extremely fast completion of a game via a glitch, it will often be considered a separate “tier” in order to preserve the old route's movies and records, as people may find the old way of doing it to be more enjoyable or otherwise interesting.
- Tool-assisted speedrun, TAS
- A tool-assisted speedrun (commonly abbreviated TAS) is a speedrun movie produced with the use of tools such as slow motion and re-recording. The basic premise of these runs is that a “tool” (such as an emulator that provides the author with features that are unavailable in regular playing) is used in order to overcome human limitations such as skill and reflex.[8]
- Unassisted, regular
- An explicit indicator that this speedrun is not tool-assisted. The term “speedrun” alone, without either “tool-assisted” or “unassisted” accompanying it, is expected to be unassisted. It is thus mostly used in order to highlight the differences between unassisted and tool-assisted speedruns.

- ^ Although the term “time attack” is used to indicate a playthough of a game's dedicated mode for achieving fast completions, the term “タイムアタック” (“taimuatakku”) is the dominant terminology for both unassisted and tool-assisted speedruns in Japan. There is no commonly used loanword deriving from the term “speedrun”.
- ^ Despite a large majority of speedruns being released in a video format, and this largely being the preferred format due to the number of players that can be used to open it, some (game-specific) communities utilize a game's native demo format due to these inherently being much more compact and thus easy to share; even such communities encode major releases in a more ubiquitous format.

- ^ With the PAL and NTSC standards in mind, screen update rates of respectively 50 and 59.94 times per second would be the most compatible choices (twice the standard rates of respectively 25 and 29.97 times per second). However, for various reasons, consoles may refresh the screen at non-standard rates. The hardware of the Nintendo Entertainment System, for example, causes an update rate of slightly above the standard: about 50.006978 in PAL regions and about 60.098814 in NTSC regions.

- ^ The Nyquist–Shannon sampling theorem states that for a periodic phenomenon's period to be measured, the sampling rate must be at least twice the period. In this context, the period is how long it takes a button to go from pressed to non-pressed and back, and the sampling rate is how often the game checks the button state. Most games check the state of a button 50 or 60 times per second (PAL and NTSC systems, respectively), while it is not necessarily parallel to the rate at which the screen is updated (The Legend of Zelda: Ocarina of Time, for example, checks the input 60 times per second on an NTSC Nintendo 64 console, while the screen is usually updated only 20 times per second). Therefore, if a button is down for 1⁄60 second and then up for 1⁄60 second, the game will only register 30 actual down states, as a faster rate than 1⁄60 is not registered (as such, one cannot simply double the speed of input, as then the game would register either only down states or up states, which it would not consider separate). This theory does not apply to actions that are performed while a button is held down. Is should also be noted that a “button” refers to any valid method of input, not restricted to a controller, and that this theory goes for every state the input method may allow for.
