Fastest completion of Half-Life (by a team)

The fastest speed-run of Half-Life (1998, Valve Corporation) in "Hard" mode is 20 minutes 41 seconds, and was completed by a group known as "Quadrazoid" on 12 April 2014. The group consists of seven players: "quadrazid", "Crash Fort", "coolkid", "pineapple", "YaLTeR", "Spider-Waffle" and "FELip". This drastically reduced the existing speed-run time for Half-Life of 29 minutes 41 seconds. However it should be noted that the team did complete the run in 317 segments and also made use of tools and automated keyscripts, which gave them extra abilities, such as "jump spam, duck spam, 180-degree turn for gauss boost and precise use-key actions".
