The world record for a Portal speed run has been demolished by an attempt that completes the entire game in just 8 minutes 31.93 seconds.
The majority of the video takes place in the lift between testing chambers, and as you watch it, the levels glide past in seconds. The new "Portal Done Pro-Er" run shaves nearly a minute from the previous "Portal Done Pro" record, which was set in 2010. Time is calculated from the moment the player first gains crosshairs to the second that GLaDOS is destroyed.
The video ends in style as the team break into a secret area housing the game's ending cake.The speed run was completed by SourceRuns members Nick "Z1mb0bw4y" Roth, Josh "Inexistence" Peaker, Nick "Gocnak" Kerns, and Sebastian "Xebaz" Dressler.
"To be SDA legal we have done our run without using scripts/cheats/hacks for any portion of the run," the team declared. "This run first started after the discovery of a new glitch, which snowballed into a whirlwind of discoveries of new tricks, skips, and glitches. We started running chambers in April, took a brief hiatus, and then resumed work in late June. The bulk of the run was completed in about two weeks time."
A detailed explanation of each segment and the methods used by the team are expanded on in an eye-watering thorough Google Document.
