I've played my fare share of developer Valve's original Half-Life, so much so that I still get nervous every time I get into an elevator or hear the words “head” and “crab” in the same sentence. But if you've never seen a speed run of the game that changed first-person shooters forever this is a good place to start.

A team of speedrunners planned out and executed a new world-record run in just over 20 minutes. That's nearly 10 minutes faster than the previous segmented record (which means there where multiple players) in a game that can take players anywhere from eight to ten hours or more to finish.

Working on your own speedrun? Here are the teams details:

* This run sets the new world record for a segmented speedrun of Half-Life on Hard difficulty with an improvement of 9 minutes. (29:41» 20:41).
* Runners, in order of total amount of segments: quadrazid, CRASH FORT, coolkid, pineapple, YaLTeR, Spider-Waffle, FELip.
* The total amount of segments is 317, 249 of which are shorter than 5 seconds.
* 107 saves/segments was made only to cause and abuse save glitches. 53 of those being at Nihilanth.
* This run is heavily scripted using the in-game console, the most widely used scripts are jump spam, duck spam, 180º turn for gauss boost and precise use-key actions.
* To use the better demo functionality and the support of higher FPS values in the Steam version, a mod have been made to restore the gameplay to the way it was before the anti-bhop patch back in 2001. The mod also features a lot of new HUD elements to aid speedrunning.
