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.

[Hacker_lyx]

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

[nise]

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.

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.

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.

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

It was thought impossible, then Zero Master happened.

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

[JMUDoc]

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

[kareharondo]

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

[AP-]

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

[DeamonSorrow]

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

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.
