Speed runs are one of my most favorite things when it comes to gaming. Watching a grand master complete a game in the fraction of the time it took me to complete it fills me with awe. Granted, there are speed runs are less fun because they use scripts or cheats, but this is not one of them.

YouTube user, SourceRuns, has posted his team’s run of Portal that completes the game in 8 minutes and 31 seconds. That beats the previous record of 9 minutes and 25 seconds. Here’s the description of the run from the YouTube channel:

Portal Done Pro-er (this run) is our improvement of the current segmented Portal speedrun, Portal Done Pro (PDP). However, to be SDA legal we have done our run without using scripts/cheats/hacks for any portion of the run. 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 2 weeks time. The final result cuts roughly 53 seconds of realtime off of PDP, bringing the total time to 8:31.93. This run is the second official run of a commercial title to be released by the Sourceruns team, and the second run to be submitted to SDA. However, it is the first Sourceruns project to be done without scripts

Check out the impressive speed run below:

As you may have guessed, this run uses liberal amounts of glitches to complete the speedrun. It almost makes sense that the portal gun would be able to create doors into alternate dimensions that allow players to skip entire sections.
