This DOOM Challenge Took 23 YEARS To Complete!

[@Gilboron]

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.

[@chriswelcome8102]

You must be prepared to do anything to accomplish the holy grail of Doom speed running :-)

[@username19237]

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

[@kastrosadam892]

A small price to pay for salvation

[@twowolveshighfiving]

I think it's pretty damn amazing that the one demon responsible for resurrection is also required to end it all in a pacifist way.

[@MechagirlSachiko]

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.

[@Wepospalient]

Doomguy wins by starting a bar fight and hiding in a corner.

[@nis5e]

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.

[@linguica]

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!

[@SilverVayne]

Dude that's sick, thanks for sharing.

[@Jinx_Skeel]

what????? oh gosh that's so complicated to understand...

[@GoodmansGhost]

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

[@Ahmrikhan]

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.

[@drawmaster77]

My brain just exploded, this is so cool

[@seangraner297]

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

[@meatmaster665]

[@suprememasteroftheuniverse]

He died for our sins. F

Master of the Universe I really love how call of duty will never escape this meme.

[@33LB]

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.

[@Roadrunner_KZSK]

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.

[@flergindergin]

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]

Very interesting, thanks

[@magickmskh]

I see you also watch Decino

[@Sinn0100]

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]

@@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

[@Fuchsia_tude]

One single exception: Barons and Hell Knights can't harm each other with their projectiles. This isn't because they use the same graphic for their attacks, as you might expect; instead, there's a specific exception coded into the monster AI the makes Barons and Knights deal 0 damage to each other. And yes, all monsters' melee attacks can damage their same species. But without something like the barrel last-damaged trick to get them to fight each other, ordinarily there would be no way for two projectile monsters of the same species to aggro on each other, because they're immune to one another's projectiles.

[@lotnemez1655]

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. PS: apologies for any spelling errors, english is not my mother tongue.

[@karljobst]

Yes I have plans to cover dark souls

[@Zelinkokitsune]

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!

[@MrTheBaron]

This is like a sports analyst breaking down an important game. I love it

[@TheFEARSlayer01]

I really enjoyed how in depth and informative this video was, you explained every bit of the run in ways that were easy to understand and get behind, and it's always interesting to see such insane runs be analyzed fully. Keep up the great work Karl

[@RecoveryPlayz]

No, he knows. He said with enough speed, you can hit the button before that other shotgunner kills yous.

[@gamewithgreg]

@@RecoveryPlayz I think what Teodor is saying is that the video says there is a shotgunner in the room but you can get past him with enough speed, yet the video shows 2 shotgunners in the room. It is difficult to see but if you slow the video down as much as possible you can see a second shotgun guy to the left by the exit button.

[@NeatChill]

I was literally waiting for some new video to come up and one from this absolute legend of a speed runner and KZbinr pops in my face! Well only watched 10 seconds time to enjoy myself ! 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!

As always, a fantastic dissection of speed running. If Zero Master is the master of speed running, you sir are definitely the master of analysis in a KZbin video.

Being a pacifist is the hardest mode in any game as well as life.

[@mastrorick]

the way the tas completes the icon of the sin looks like the finale of an action movie: the hero has the main villain in front spamming to him unmesurable amounts of creatures. Unarmed, resolves the only way is to kill the big demon from the inside. Aware the creatures are braindead, he does a leap of faith above the flaming ones, who attacks him with scorching flames. The demonic fire burns his suit, skin and muscles, but provides the momentum to reach the interior of the beast, and the flames he carry on do the dirty job

[@sleeplibrary2845]

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.
