Speedy passage of the game ( English speedrun or runthrough ) - passing a computer game for the smallest period of time as part of a competition or for entertainment. With high-speed passage, the player shows not only his skill, but often uses unusual tricks for this game and features of the game that are not provided by the developers. For demonstration, records of high-speed walkthroughs are created in one of the video formats, or in the demo file format of the game itself.
In an effort to reduce the travel time, the player skips possible branches of the storyline, often breaking it altogether, interrupts any video inserts . Sometimes a game allows you to perform an action not documented by the developer (for example, rocket jump ), which in a number of conditions helps to reduce the time spent on passing the level. Some levels can be designed in such a way that there is a shorter way to certain areas (for example, leaving the level) that you need to reach in a roundabout way. Sometimes, due to flaws in the program code of the game, it becomes possible to perform actions that are not available under normal conditions (for example, to pass through walls or jump a long distance).
High-speed passage can be considered as passing a game in which the player does not lose time exploring the game world, but follows directly to the intended goal. To do this, the player has to carefully examine the playing space in advance, optimally plan his route and at the same time, with a certain degree of probability, hope for good luck. After all, the only mistake can lead to the fact that a carefully planned and perfectly executed performance will be spoiled, and the player will have to start again. The player must also have patience and perseverance, without losing concentration during the passage.
Sometimes a player has to spend several months or even years to get a high result. After all, the player must not only know the shortest path, all the problems of the route and the game’s bugs along the way, but also wait for the most successful combination of random factors, ideally completing the critical parts of speedran that require high skill , and passing all the routine sections at the proper level using their skills acquired through long practice.
“ Doom ” was one of the first games around which a community of speed players was formed, which arose in 1994 from news groups posting demos on FTP and websites . The current became widespread with the advent of the Quake done Quick series for Quake .
Thanks to many tricks and tricks, one of the most common bases for high-speed passage was the game " Metroid ". In such games, there is a built-in player reward system for completing the level for the shortest possible period of time.
The game " Quake ", the passage of which according to the authors ’intention should take several hours, was completed in 11 minutes 29 seconds  .
According to the Speed Demos Archive website dedicated to high-speed computer game passing, the record for the complete passage of Quake (implying the destruction of all enemies and finding all secrets) was set at the highest difficulty level on October 18, 2005 by Justin Fleck  , who completed the game in 1 hour 9 minutes and 33 seconds  .
The Half-Life game, designed for approximately 8 hours of playing time, was completed collectively in 20 minutes 41 seconds due to the possibility of very quick movement between locations - jumping , as well as using scripts from a standard game console. The passage was a montage of several segments, alternately recorded by different players. Location loading screens are cut out. The total number of segments is 317, 249 of which are shorter than 5 seconds.   Similarly, Half-Life: Opposing Force (19 minutes 23 seconds)  and Half-Life: Blue Shift (25 minutes 3 seconds)  were completed . Also, more recently, the SourceRuns team completed Half-Life in 6 minutes and 26 seconds  , using a recent open trick called Save Warping.
Opportunities for speed passage can be detected in RPGs . An example is the Morrowind game, completed in 4 minutes 19 seconds  , although the creators planned that it took several tens of hours to complete the main storyline.
Some games to which the gaming community has already lost active interest, after setting records for high-speed passage, regain a lot of fans who return to the game. An example is the 2001 game Diablo II: Lord of Destruction , which again became popular two ago [ when? ] , when the first results of passing the Normal level of the game appeared in less than 3.5 hours. At the time of March 11, 2019. The record for passing Normal is already 1 hour 10 minutes 31 seconds.
