Half-Life in 20:41

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!
