This one isn’t for the queasy.
YouTube user quadrazid posted this 20:41 second run through 1998’s Half-Life, and it’s a thing of potentially motion sickness-inducing beauty.
The video’s author explains that the speed run has been in the planning stages since 2010, involving new routes, tricks, and figuring out ways to beat the previous record of 29:41 on the game’s Hard difficulty setting.
For you purists out there, quadrazid concedes that they did use a handful of keyboard scripts to help with the speed run (“[T]he most widely used scripts are jump spam, duck spam, 180º turn for gauss boost and precise use-key actions”) and also utilized a mod which rolled back some of the updates and changes to the game on Valve’s side over the years.
It’s still nuts, though.
