Presenting Half-Life 21.
Starting back in the summer of 2010, the estimated time for this run was thought to be roughly 27 minutes. However, after almost four years of painstaking planning, theorycrafting and execution, we have arrived at our final time, smashing all of our wildest expectations.
Not only do we owe this new world-record time to all the new tricks we’ve discovered, the new routes we’ve found and the new ways we’ve
learned to manipulate the game. A lot of the improvement from the first estimation and the previous world record (29 minutes, 41 seconds)
comes from the very hard work and countless hours put into perfecting each and every segment, no matter how short or trivial. 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.
Enjoy, Half-Life in 20 minutes, 41 seconds!
- 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.
- This run is heavily scripted using the in-game console, the most widely used scripts are jump spam, duck spam, 180* 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. Read more and download here.

The videos are available with both 60 and 120 fps. 120fps is recommended only for users with more than 60hz, preferably 120hz. The files may also be heavy for old computers to play properly.
I strongly recommend Media Player Classic for the 120fps verison, it will play fine. VLC however will not.
For details about chapters, maps, segments, players and times, there is a detailed spreadsheet.
