Portal 2 speedrunning isn't just about who can get around fastest: another category exists that focuses entirely on getting around using as few portals as possible.
As shared by prolific Portal 2 speedrunner PerOculos, the latest breakthrough is on the Chapter 4 level Column Blocker, which had previously been completed with a minimum of two portals. Back in 2016, another speedrunner called Jetwash demonstrated that a zero-portal route would be possible for the level, but admitted some "crazy bullshit luck" would be required for the method to work. After a lot of practice, PerOculos managed to jump to the cage, turret climb and then perfectly align that (frankly ridiculous) turret throw.
"In my brain, I practiced enough to know I only needed to mind two things," PerOculos said. "Timing the throw, and throwing it up high enough, and it came together so well."
