This Portal player can beat the game in less than 10 minutes, with many levels flying by in mere seconds. How can a Portal speed run happen so fast? Break Portal apart at the seams, of course.
This sprint through Valve’s first-person puzzler is a combination of speedy backwards jumping, slipping through cracks in the world and screwing with Portal’s rules. It’s a great watch, even if you spend most of your time looking at elevator doors, wondering “How the hell did he just do that?!”

Tuesday, December 14, 2010 at 6:10 PMI’m pretty sure he is deliberately singing off key… and that is very hard to do! Especially to stay off key as well as he did. I thought it was a great way to end the vid. :P
