This is a segmented Portal speed run by Nick “Z1mb0bw4y” Roth, Josh “Inexistence” Peaker, Nick “Gocnak” Kerns, and special guest Sebastian “Xebaz” Dressler, in the time of 8:31.93, and in 24 segments.
There were no cheats, hacks, or modifications made to the game while the speedrunning took place. Everything you see in this video can be done on a current Steam version of Portal without using any console commands. Any part where the video “stutters” or when a “console box pops up” signifies a segment. The console box is a demo artifact, and we couldn’t fix it from popping up.
