Half-Life Speedrun Breaks World Record At Just Over 20 Minutes

After months of theorycrafting and planning, speedrunner quadrazid and his friends were able to run through Half-Life — a game that's anything but short — in 20 minutes. And the fact that it's almost 10 minutes faster than the previous world record shows how perfectly executed their run was.

You can see the entire speedrun above, it's just amazing. The team's also shared a few technical details about this run:

* This run sets the new world record for a segmented speedrun of Half-Life on Hard difficulty with an improvement of 9 minutes. (29:41» 20:41).

* Runners, in order of total amount of segments: quadrazid, CRASH FORT, coolkid, pineapple, YaLTeR, Spider-Waffle, FELip.

* The total amount of segments is 317, 249 of which are shorter than 5 seconds.

* 107 saves/segments was made only to cause and abuse save glitches. 53 of those being at Nihilanth.

* This run is heavily scripted using the in-game console, the most widely used scripts are jump spam, duck spam, 180º turn for gauss boost and precise use-key actions.

* To use the better demo functionality and the support of higher FPS values in the Steam version, a mod have been made to restore the gameplay to the way it was before the anti-bhop patch back in 2001. The mod also features a lot of new HUD elements to aid speedrunning.

    I rember Quadrazid's blue shift speed run with his mates. Insane.

    Wait so, he falls from so high up and doesn't die? And how does he run that quickly? Looks like an insane form of bunny-hopping!

    I am sorry, but I just can't be impressed by speed runs that modify the game. A proper speed run should be the base game only, no hacks, no mods, no cheats. No editing the game of the game in any way.

    Correct me if I am wrong, but I don't think there is a "non cheating" way to get over 2000HP in the game.

      There is a door that you can do a glitch with that gives you insane amounts of HP. Everything in this run is base game and no cheats (cheats: as in no console commands or external tools/mods).

        ....Unless you're talking about another run.

      The HP boost is in the original, it's an underflow bug from that door doing damage.
      If you were watching the game unmodified you would see the HUD HP looping up to 255, the only modification here is that the 'true' hp is actually displayed correctly. The only real benefit is that they can more easily optimize the time spent in that doorway.

      The run uses a modded version of the game that brought back a version of bunnyhopping that did exist in the game at an earlier time as well as providing several HID elements such as speed (which don't even make it to the final video). AFAIK, many Quake runs do similar things.
      If you're after more 'vanilla' speedruns, single-segment scriptless runs may be more your style (There are a plethora of people streaming these on Twitch)

      Correct me if I am wrong, but I don't think there is a "non cheating" way to get over 2000HP in the game.

      It is 100% possible to get 4,000HP in the unmodded game, do the same thing he did and get yourself stuck inside that particular doorway and your health continually goes up. The only difference is that the game was modded to display all 4,000 hitpoints whereas the vanilla game won't display more than 255, so the mod here provided additional viewer clarity and didn't modify the mechanics of the game.

    This run is heavily scripted

    No thanks.

    This run is heavily scripted

    You should see me no-clip the entire game in 7 minutes....

      does that actually work?

        i tried once, stopped about half way but yeah it was working... kept getting lost though...

    You should see me no-clip the entire game in 7 minutes....

    There is a difference between scripts and cheats... Scripts automate menial things such as jumping at the correct time while bunny hopping or crouching at the right time to avoid fall damage. Both of these things are doable by a human but made easier with a script.

    Noclip, on the other hand, requires cheats to be enbled, and that will produce a rather unexciting video.

    EDIT: lol, this sites javascript is so broken that I can't even reply or use the formatting buttons

      its a very fineline between the two i assure you... there is a heavy amount of scripting involved that is blatantly obvious watching this.... this is speedhacks galore... none of this is possible or doable by a human without said sctipting...

        I won't deny there are a lot of scripts (And the triggerdelays for teleporting through some levels (Like into On a Rail) are almost exclusively script-based.

        "Speedhacks" though, I'm not sure what you mean - it is simply just perfected bunnyhopping, a script is used to remove the issue of not jumping at the perfect time (It literally just spams the space bar, you can achieve the same effect by binding jump to your mouse wheel and rapidly scrolling).

        If you want to see things not doable by a human, take a look at YaLTeR's Half-Life TAS Mod videos on YouTube, the difference in execution between a human (This run) and tool is huge.

    Scripts... BS. This is so lame.

      Don't view this as lame because of scripts. View it as a great technical feat. Movies aren't "lame" because of CGI. They (arguably) improve the movie and take many hours to complete.

      If you've ever recorded a speedrun, you'll know how tricky it is getting things done, especially if you can't "savestate" like you can with SNES / NES / N64 / etc. emulators.

      So do as I am, sit back and enjoy the show and marvel at how they put it all together!

        No I am sorry, but this is like putting on cheats in Darksouls and finishing it on NG+ 2. It is like cheating in GTA... NO ACHIEVEMENTS FOR YOU!!!

          I see your point. But what if you 'level out' the playing field by setting aside a record solely for scripted runs? Some years ago I played Tony Hawk's Pro Skater on the PS2 and joined a few online maps. Many of them had cheats enabled, but it evened things out, because you had the cheats on too. In the end it wasn't about who had cheats, but who could make the most of the cheats.

          But there you go. HL done in 37 minutes, on hard mode, single segment, no cheating or scripts. There's also a TwitchTV video which shows a guy playing the game with some "cheating" (reloading saves only, I think? Maybe some heavier glitches, I didn't watch the whole thing) and he includes a webcam shot of himself playing so you can see him use the keyboard and mouse.

          Given that there's at the least only 8 minutes difference between the old "scripted" record and the clip I've linked above, I'd say scripts help get stuff done, but don't do stuff for you -- you still need to know how to play and plan your game out accordingly, because falling too far or jumping a millisecond too late could cause a timing or health problem further on down the track

    you idiots going on about "scripts very lame" etc are obviously just casual morons from the current gen of achivement spoiled brats. the technicality and ability of these players, both in scriptless and scripted runs, outdo any gaming ability you have by ten-thousand fold. enjoy your GTA achievements you complete plebs. christ.
