    A pacifist giving his life to kill the icon of sin, is truly poetic.

    So basically - to beat the Icon of Sin pacifist-style, you have to let your enemies turn you into a living bomb and launch you into the boss...
    That is very, very metal.

  • Gilboron
    Gilboron 3 years ago +3527

    I think it's a nice thematic capstone that in order to beat the Icon of Sin in a pacifist run, Doomguy has to sacrifice himself.

      Yeah I was gonna say. That’s pretty meta that the last level left unbeaten pacifist is the last level in the game.

    • Mechagirl Sachiko
      Mechagirl Sachiko 3 years ago +20

      The Doom Rogue-Like Angel of Pacifism challenge follows the same basic idea. When you reach the final level, the only way to kill the Spider Mastermind is by sacrificing yourself.

    One wrinkle that was skipped is just how lucky ZM got with the infighting. In Doom, things "remember" what the last thing to injure them was. This includes barrels. During the run, at one point the shotgunner up above happened to nick an unexploded barrel. The barrel then "remembered" that it had been hit by that shotgunner. Then a little later when there are two imps left, one of the imps hits the barrel with a fireball and it blows up, killing one and injuring the remaining imp. The code looks to see what hurt the final imp, and then checks if the barrel "remembers" who damaged it. The barrel's "memory" is still of the shotgunner, because it's only updated when it is injured, not killed, and so the barrel tells the imp that it should be mad at the shotgunner instead!

      Admit it, you learned that from Decino's video on infighting right before watching this one =P Amazing facts none the less.

    • Ahmrikhan
      Ahmrikhan 3 years ago +56

      This is also detailed in decino's latest video about monster infighting, if anyone else needs a visual aide to help in figuring it out. But Linguica did a great job explaining it.

    It seems fitting that the last level of a Doom pacifist run requires the hero to sacrifice himself to stop the evil.

      it seems fitting that doomguy basically becomes jesus Christ on the last level of a doom pacifist run, given that doom is the most Christian video game there is.

    I can’t believe they turned Doom into a puzzle game...

  • Roadrunner KZSK
    Roadrunner KZSK 3 years ago +363

    11:29 Imagine you are the doom guy who is about to sacrifice his life in an ATTEMPT to end it all. You jump on the elevator and you are thinking "Will this work? Will my life go in vain and the whole universe remains overruled by this evil for ever?" You turn around while the platform is rising and the very last thing you see is the terrifying view on all those archviles raising their hands and are about to obliterate you in a few seconds. For a moment your skin freezes feeling the touch of death reaching it's arm to you and immediately after your skin starts to burn. You quickly jump as far as you can and the fireblasts rip your body mid air launching it across the room.... There is nothing more, only darkness. You will never know what happened next.

  • Tristan Crosley
    Tristan Crosley 3 years ago +255

    Fun fact: Monsters in doom that are the same type cannot infight or even deal dammage to each other. The reason Zero Master was able to let the shotgunners/zombiemen kill each other is due to hitscan. If these monsters shot projectiles, like the imps fireball, they would not deal dammage/infight. There is a youtuber named Decino who has some annalysis videos looking into these sort of mechanics for DOOM if anyone is interested.

    • mathprodigy

    • Puppet
      Puppet 3 years ago +7

      yeah except if an imp attacks a barrel and that barrel explodes on another imp then they will infight. However their projectiles still do no damage to eachother.

    • Sinn0100
      Sinn0100 3 years ago +7

      Actually, all hitscan enemies can infight. What I don't understand is how he got two imps to fight after the barrels were gone. The one imp kills the other with standard fire which should be impossible.

    • SyoShinozaki
      SyoShinozaki 3 years ago +8

      @Sinn0100 I've heard many years ago that Imps' close range attack (claws) do hurt other Imps, so when they go infight they hurt each other with their claws

    Man I don't comment often. But Karl, if you read this I just want to give you props. I instantly click your vids when I see them, especially the doom ones. It's so simple, yet you make it so entertaining and with very knowledgeable information. Keep up the amazing work bro! Of course I won't forget the editor either *cough* having to cut that many deaths off when you play haha.
    Jokes aside, your videos are of quality. I really hope you become big

    • Lot Nemez

      True. Because of this channel, I realized, that speedrun is a unique kind of online culture (not that the games are to be played online but you share and compare your results online) with various disciplines. Very interesting.

    I learned about you and your videos when i watched the video about you doing the 52 in goldeneye dam, i have never played goldeneye, doom, quake etc but your videos are absolutely legendary
    you break down everything while being entertaining and to the point, i can watch one of your 20 minute videos and it looks like i only watched a minute because of how good they are.
    You are the true definition of a good content creator.
    Do you have intentions of making videos about more recent games? I'm a big fan of games like bloodborne and dark souls and find watching speedruns of those very entertaining despite not being a speedrunner myself.
    Keep being an absolute legend Karl, we'll all be here to support you.

    I'm getting right into these challenge vids at the moment, I just finished watching a Donkey Kong Country no enemies death attempt among others. This ones an incredible story, even with me not being a huge fan of DOOM I found it enthralling how far someone would go to figure out new ways of playing their old favorites. It's giving me ideas... Great work mate.

    Yesss I am so glad that you did this topic! I actually watched his explanation video of this and the original run. But you make it so much clearer what's going on by explaining everything in great detail. Plus the icon of Sin bonus stuff at the end is absolutely insane. Thanks for another excellent video Karl!

  • Milo Novik

  • Zelinkokitsune
    Zelinkokitsune 3 years ago

    I think with the TAS that goes understated is so hard it is to just get the Archviles to spawn the numbers required to do the final launch. It's around 0.78% that an archvile would spawn and ZeroMaster uses 30 of them in the TAS. It's utterly insane for odds!

  • riffbw
    riffbw 3 years ago

    I remember the day each of these dropped. Zero Master blew my mind with each one. It's crazy how long Underhalls took, but it was gripping. It's insane that it requires a ghost camera to adequately explain it.
    The TAS Icon of Sin was a thing of beauty. I don't know how long it took to get that created, but that might be the ZM's best work to date.

  • 2ndShiftSupremeOverlord

  • shaman zen ghost
    shaman zen ghost 2 years ago

    tool assisted accomplishments normally feel a little irksome but the exact mechanism that the level is conquered, where a swarm of the most powerful and hated monster in the game accidentally destroys the overlord monster by way of an incredible leap-death combination - is 100% excellence, for the first time ever Tool assist has given me rightful grins.

  • Allstin
    Allstin 3 years ago

    It’s crazy what really goes into this, isn’t it?!
    And the Romero head isn’t on the enemy count I thought, just the starting revenant is the only enemy in the map at first (at least with GZDoom’s alternate HUD, which isn’t used for these runs). But I guess it still counts!

    Being a pacifist is the hardest mode in any game as well as life.
    Pacifist doomguy knew this, and with his sacrifice he overcame mans basic instinct of rage, chaos and destruction and being a pawn of a weapon.
    instead he became the element of evolution.
    F to pay respects for Doomguy end boss sacrifice.

    Isn't there another level that is pretty much impossible to beat pacifist? Stronghold from TNT if I remember correctly. It was at one point deemed impossible to even simply finish the level with no restrictions on the nightmare difficulty, and it took a really long time before anyone actually did it.
    So doing a pacifist run of that seems pretty much on the same level as the icon of sin part :)
