Portal is one of those games that you can brag about how fast you got through it. It’s not the longest game, start to finish might take a gamer a hour if they apply themselves. However, a gamer by the name of DemonStrate beat Portal in 9 minutes and 25 seconds. How did he do it? Not by memorizing the puzzles or by practicing with the portal gun. He did it by exploiting the game’s glitches, shooting portals through clipping glitches and most importantly walking backwards.
