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

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

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.

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.

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!

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

•Came to be called an absolute legend •Stayed for the amazing content

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.

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

Kills: 10800% Damn!

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.

Kills - 10800% Yep... that's Doomguy.

R.I.P. Doomsguy 1993-2019 He saved Earth from demon invasion by sacrificing himself and without harming a single demon

It was thought impossible, then Zero Master happened. -DOOM challenges in a nutshell.

"civil war" is an interesting way of saying monster infighting

Favourite part of any of Karl's videos: "to achieve T H I S run"

9:45 did you just say Shadow Zero instead of Zero Master 😂

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

I love how you approach to the topic and explain everything step by step!

"You absolute legends" *blushes

Your content just gets better and better. Not only one of the best Perfect Dark/Golden Eye players ever, but a great content creator. Love your work.

I can't believe Doom had demo files back then, the third person view is great feedback.

9:45 "Shadow Zero" You mean Zero Master? 😂

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

That icon of sin strategy by looper was breathtakingly beatiful.

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!

*realizing being called an absolute legend, is the only compliment I'll get today*

Cacodemons are probably my favorite enemies from Doom. They just look so cool.

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

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.

Well, now im addicted to this channel.

9:44 Shadow Zero lol someone was playing some Mana

I like when doomguy moves hes super fast. We ate just so used to running fast!

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.

Doomguy: The problem of being faster than light is to live in darkness...

I was literally waiting for some new video to come up and one from this absolute legend of a speed runner and KZfaqr 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!

Seeing the title and "pacifist" on the thumbnail made my mind jump straight to map02. Great video!

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 KZfaq video.

10:26 there is a second shotgunner in the room, he's visible for one frame (left side)

I love how much detail goes into your videos. So much homework done, I dont even play Doom myself but you get me hooked. Thanks, you absolute legend!

Icon of Sin theory: *Exists* Random SpeedRunners: Challenge Accepted

My jaw fucking dropped when I saw that TAS. I thought he was just gonna get in the hole so he could punch John Romero to death but using the fire from the Archvilles is genius.

Finally! Was buzzing for another Doom or Quake speed running video, more of these please!

Love these videos man. Very informative and professional with the way you explain what’s going on, without silly jokes or cutaways.

Imagine the day this strat manages to be pulled off, that's going to be one of the greatest days in the history of gaming.

Love your stuff, love your style. Please do more doom!

This is one of my favorite channels, you do a great job explaining things!

Some of these strats are absolutely insane.

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.

crazy how Doom has lasted this long. I still play Doom 1 and 2.

Thanks for the great content Karl, in a time where my attention span is at minimal levels, I always watch your videos all the way through.

i watched zeromaster's video couple weeks ago, figured you would do a video about it some day, but then this video showing up right after i just watched was almost like you were reading my mind. great work as always.

Hah, pacifist "challenge". I do the pacifist challenge in every game, bullets and the fall killed them not me, honest! 😇

It always blows me away how people are still unlocking these secrets within the game that allow for faster/more optimized runs. Incredible.

i love this because it doesn't rely on glitches but just massive amounts of trial and error.

I watched Decino cover this topic a while back. It's always cool to see someone else's view. Thanks for the continued Doom content, Karl. Keep it up!

I have so much respect for the few speedrunners that are also content creators! You all do so much for the world of speedrunning making it accessable like this!

Good stuff as always. Love the attention to detail.

That strategy at the end is extremely impressive I would love to see somebody do it while playing, but I know it's impossible Seriously I have always loved doom runs, they'res just something about them that makes them unique to all others

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.

okay, I'll admit, having the demons kill each other is a pretty hilarious strategy

Zero Master is an absolute legend

The last bit saying impossible to complete icon of sin pacifist hurt my heart. And the only way to theoretically beat it is to be burned to death. Yo I feel like I relate too much to this like my brain hurts like it feels like it's burning.

Look foward to these vids everyday. I still play original doom on my xbox at least once a week and have actually found a few secrets recently on my own! Best feeling ever

great video karl as always!

Another amazing video man! Loved it! Keep up the great work :D

Yet another impeccable KJ vid. And congrats on the family news!

Excellent video! The trick with the Archviles is just too awesome... pure Doom oddity.

Awesome content. I find it fascinating how true legends optimize games down to the very understanding of the code. That's dedication.

I like to imagine that every playthrough of every doom game, doom guy experiences and remembers. That's why he's so good. He's had lifetimes of practice. As well as untold number of deaths.

Ah, Underhalls. The level you get the super shotgun for the first time. And you mean to tell me people had a hard time doing a pacifist run? I submit that the real reason for this is that they couldn't resist blasting zombies with the best fps shotgun ever made, the SSG.

Another great video. Narration and presentation on POINT, and very interesting subject matter. Love it

Zero master is absolutely a legend

I'm baked

Just found recently your channel. All videos are very interesting and I always watch to the end. Keep up the good work! 😀

Been enjoying your vids recently, good stuff man

Dude, I've watched Zero Master for a long time now. He is a *legend*

I don’t even play doom but I loved that you included the answer to the title question in the thumbnail and the video was great!

11:31 I've seen that part before. Man that's epic! Coolest way ever to finish the game in :-)

I was 3 when I first played this, it scared the living shit outta me, I can still feel a little fear from back then inside me now while watching it

The fact that Karl does videos on my two favorite speed games (Doom 2 and Goldeneye) makes him my tied for first speedrun content maker. Goose is tied with him

As a person with a casual interest in speedruns, I love your channel. Always interesting!

Yeah see how hard this shit is? Yet Gandhiji has already done life on this difficulty. Hail to the King!

I really do enjoy how your viewers are the absolute legends

Newb: internet 1337 haxxor: internets

Nice to see doom speedrunning get more attention. Thanks for that karl!

Watched zeromasters run and linguicas explanation but still coming back for more on this insane run

With Karl and Decino I feel like I know everything there is to know about Doom and yet there's still more being discovered today.

your videos are so entertaining, love watching them

I always look forward to these videos. Love it

i love this channel,so much info in a well made video! what a legend ;)

"Yeah, I'm a pacifist. I'll past my fist...through your face."

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

Playing Doomguy "True Pacifist" style is like trying to force Wolfwood to live by Vash's philosophy.

4:18 I THOUGHT I got through that gap when I first played it! Thank you!

Blindfolded Doom speedruns are the future!!!

We may be legends, Zero Master is pure GOD of DOOM

I didn't know that the door at 7:00 couldn't be manually closed. That makes the blue keycard room ten times harder than I thought it would be.
