8. Portal Lets Make This Quick
http://youtu.be/mC47O6mKHJY Often, speed runner looks to exploit glitches in-game to skip past entire sections, in order to attain the fastest possible run without using hacks or cheats. The above is one such run, which derails GLaDOS' twisted little game in about as much time as it takes to cook up a microwave dinner. So fast is the run that many of the YouTube comments on the YouTube page (the clip was posted to
sourceruns) question its authenticity; cry that it's simply
too fast and as a result hacks must have been used - others swear by its adherence to normal speed runner rules and are appropriately impressed. What do you think?
