The latest in IGN's "Devs React to Speedrun" series. This time Adrian Finol, Robin Walker, and David Speyrer from Valve react to speedrunner waezone's run through Half-Life 2.

Yeah this video is great, any HL2 fan should watch it!

The ratio of time to create the level to the time waezone took to complete it. šŸ¤£

i love that at one point in development Gordon had physics and could kill himself by walking into a wall. they really need to bring that back

I love when they're joking about patching the physics bugs the day before a major speedrun kicks off.

Why's he running backwards, is that quicker? Pretty impressive, no idea how he gets so much speed! I'm playing through half life 2 again on geforce now and after a few minutes he's already further than I am after a couple of hours.

The part where he's backing the airboat into the wall and just launches through the level is hilarious.

I love this exchange

'Wow the airboat sections alot longer then I remember'

'Yeah because nobody thought that section was long at all'

Yes bunnyhopping backwards is faster. Valve tried to stop people going fast by bunnyhopping forward in the 2007 engine update by applying negative acceleration when you tried it so speedrunners do a quick 180 and use the negative acceleration to go super fast backwards.
There is an outdated Summoning Salt speedrun history video that explains some of these tricks.

Man, I wish they'd do one for Half-Life as well. It's the most spectacular speed run I've ever watched

Fantastic series. I love hearing all the behind the scenes stories the developers end up sharing.

There's a speed limit on some of the fast movement tech while the player is moving forwards. Devs never considered that players would simply turn around.

Awesome thanks!

I re-play HL2 recently and I still remember how I disliked the airboat section very much; stretched way too long. Wish I could learn that speedrunning technique to skip the section entirely.

This was super cool to see! Love hearing developers talk about their game in a relaxed manner.

Does not make me want to replay the game though, remembering all the talks you have to 'stand' through haha. Maybe I'll just grab some boxes and teleport myself away.. šŸ˜Ž

How is this even remotely humanly possible? These people are literally wizards

Not only are the movements and timing on a whole different dimension than what I could ever imagine doing, but that they remember every tiny detail of the entire game down to the exact square inch of game space to be able to pull of these maneuvers. Absolute madmen.

This is segmented, means that after each small segment they save and if they fail any trick, they just load back a few seconds. They may do hundreds of attempts for each trick until they get it perfect, so this is not realtime, but it's still shows that it's technically humanly possible. Still, mighty impressive.

There are realtime runs on YT that do it in 27 minutes:

Here's a commentary video from the two main runners, where they break down pretty much the entire run. It's really long but a fascinating watch if you care about knowing the details. There's an insane amount of planning that went into it.

I love how they keep attempting to talk about how they developed the area the runner is in only to abruptly stop and be like "well nevermind he's past it now" LMAO
