Half-Life finished in under 21 minutes

Speed-running collective quadrazoid has set a new world record by finishing Half-Life in 20 minutes and 41 seconds.

The successful speed-run, which smashed the previous record of 29 minutes and 41 seconds, took four years of planning and practice to execute, according to the group.

“This run has truly been an endurance test for everyone involved, and we’re extremely happy to finally be able to share it with you,” the runners said.

The run was executed on Hard difficulty, and is the amalgamation of various segments performed by a group of runners. The actual players are: quadrazid, Crash Fort, coolkid, pineapple, YaLTeR, Spider-Waffle, and FELip.

It must be noted that this record-breaking run uses custom scripts for “jump spam, duck spam, 180 degree turn for gauss boost and precise use-key actions” and is cobbled together from 317 segments; 249 of which are shorter than five seconds.

Below is a video of the record breaking run.
