New “Portal Done Pro-er” Speedrun Smashes Previous Portal 1 World Record


A year and a half ago, in late 2010, Michael “DemonStrate” Yanni created a jaw-dropping 9-minute speedrun of the original Portal, titled “Portal Done Pro. It was the new world-record time for the fastest playthrough of Portal 1, and understandably, it was widely publicized at the time.

But you know what they say: records are made to be broken. And yesterday, PDP’s world record was not only broken, but smashed wide open. Read on!

Jaw-Dropping Half-Life 1 Speedrun: Single-Segment, in 32:55


Speedrunning! It’s been around since 1994. Some consider it a form of art, some don’t. But what we do know about it is that it is damn fun to watch! I mean, come on. Whether you’re watching a Quake speedrun, a Metroid speedrun, or what have you, it’s almost as entertaining as actually playing the game in question.

There’s two main types of speedruns: single-segment speedruns and multi-segment speedruns. The latter is a speedrun in which the runner does not actually do it in one sitting – he does it in multiple sittings, in multiple segments to ensure perfection and correct any mistakes. The former is a speedrun made out of one single segment. No pausing, no saving. One single sitting. That means every time you make a mistake, you either bear with it, or call off the entire thing and start over. So a single-segment represents the ultimate test of skill and endurance.

The Valve community hasn’t shied away from speedrunning either. Last year’s astounding 9-minute Portal speedrun by DemonStrate still holds the world record for Portal speedruns. And there’s also been numerous Half-Life speedruns – single-segment, multi-segment, crowbar-only, you name it, these guys have probably done it.

The world speedrunning record for Half-Life 1 is still held by Blake “Spider-Waffle” Piepho, who completed his infamous “Half-Life in Half an Hour” speedrun (for which a series of commentary videos can be found here) in October of 2006, with a time of 29 minutes and 41 seconds. Blake’s also done a number of other Half-Life speedruns.

But let’s get to business, shall we?
