@sheparddog117 you can’t shoot at the very top - you have to time it. What I do is shoot once when the platform lines up with the Icon’s “chin”, and then time a rocket when I run off of it. I know that’s probably not too helpful, but it’s hard to be specific. Use what I said as guidelines, and practice it.
The Free Version is fine. If not that, then the album version. Unless you have boxed copies of all the other DOOM games, in which case I'm going to need your address, k thanks.
By the way, Samuel Hayden stating that Icon of sin is getting stronger with every second on earth is a really nice touch, because in Doom 2 this boss fight was just pure race against time, the longer you stay in there, more monsters start and keep spawning, overwhelming you
The icon of sin also keeps spawning demons in doom eternal, starting with fodder and the longer you take fighting it, more heavy demons start spawning.
As a child, I remember map 30 and the Icon of Sin being by far the most terrifying thing in Doom. It was gigantic, so unlike any other demon, there was nowhere to hide from it. The empty-ish hall design only exaggerated this. And the fact that it could kill you even with the god mode on completely freaked me out. I had it in my worst nightmares. The best video game boss ever.
Its not just the Icon of Sin. Forgot which doom game, but there was also the first part where you would instantly die (by telefragging yourself) if you didn't cross the "islands" through the right path. Also yeah, telefrags aren't blocked by iddqd.
It's funny, it seems to show up in just about everything, but I'm pretty sure MAP30 is also the first time I heard it. It always distracts and annoys me when some other piece of media uses it because it's just far too recognizable.
Fun fact, romero being the boss head wasn't planned from the start, a few others put his head in as a joke and weren't gonna tell him before release but he found out so he recorded and snuck in the voice line without telling anyone for a surprise to the other id dudes
9-25-23 So, some of the other developers of Doom tried to sneak his head into the Icon of Sin as a joke. However, John Romero would discover this fact, and would sneak a voice line into the game without telling anyone else. He surprised the people who tried to surprise him. Funny.
Everyone: Icon of Sin ACTUALLY says "To win the game you have to kill me John Romero"! Me: giggling because decino saying "reaction time" sounds like "erection time"
@Agent 005 Sometimes a lot more complicated... But honestly? Sometimes not at all that much more complex. AI in games is still extremely primitive in more cases than you might imagine... Sometimes the AI in a modern game barely surpasses the complexity of pacman. On the other hand, sometimes it's so complicated you'd need to do a 3 year long study just to make sense of it all...
@@jonbartosch1903 No. It's just a random joke in the video, referring to Romero's recent wad for Doom. "To win the game you must kill me John Romero" was the original reversed message.

@@tehberral They already got the classic skin model on Eternal. If they hire a programmer to give it gameplay mechanics, remaster the original levels in idTech 7, and make a Generations style of gameplay (Classic Doomguy cannot jump, can't dash while the Modern Doomslayer can) and voila!
I even got myself a concept for the final Icon of Sin fight now that I thought about it. Both the Doomguy and the Slayer join forces together and head to the portal to the destroyed buildings and he's right there (the full-body one in Eternal) roaring that famous John Romero line menacingly. Both characters take turns in fighting him, as he starts spawning demons using Hell Energy. The Slayer would weaken the body while Doomguy fires on the head, which would stagger him for a while, hence giving the player more time. In the end, after it's almost killed, both of them fire volleys of rockets to it's exposed brain, instantly blowing it up.
I think there's something profound about Doom. As I've watched these informative videos that get deep into the code I appreciate the game more. It was made so long ago, yet the software was ingenious at the time. It's optimized so well, that it has basically become possible to run doom on anything. I love these videos, but I gotta go buy the sigil box set.
_Fun Fact that you probably knew._ The Icon’s brain spit sound is used in multiple movies and other games! _This has been, The fun fact that you probably already knew._
@@ChusenOne It's probably similar to the Doom door sound. While I always mentally associate it with Doom, you'd be surprised once you start listening for it, how many films in shows up in.

First played Doom 2 all the way through on I'm Too Young To Die with god mode way back when I was 8 years old. I made it to map 30 totally confused what to do, running all over the map, when suddenly I died with a big red screen. Scared the bejezus out of me. Now I know it was just a spawn cube telefragging me.
I have a very distant memory of this happening the first time I ever played the map, would be about the same age and confused me for years. Told myself iddqd must have a time limit
I remember some rumors saying that the Icon of Sin could have been a way bigger and more powerful Cyberdemon in previous concepts. And just like all rumors... It was unfounded.
it's worth noting that despite the fact that you can typically only damage the icon of sin with rockets, the romero head actor doesn't actually have any sort of damage immunity. instead, the head in d2m30 ( as well as many, _many_ map30s that follow ) is just too low to hit with most weapons. but, since splash damage only checks proximity on the xy axis, rockets are still able to damage it by hitting the wall behind it and catching it in their explosion. subsequently, ports like gzdoom which make splash damage use 3d collision detection have to "cheat" and ignore that added functionality _specifically for the romero head_ just to make sure that map30 doesn't _break_ also, the explosions from a dying romero hero _don't_ actually hurt ... under the conditions of a typical map30 setup, anyway. the S_BRAINEXPLODE states don't call A_Explode like the normal rocket death states, and while the spawned actors are 100% standard rockets forced into a non-standard state ( meaning, they're still projectiles - even though they're _visibly_ exploding, the rockets haven't actually _died_ ), actors only check to collide with other actors during P_XYMovement. which, as the name suggests, handles movement on the xy axis, not the z one. so, normally, they don't deal explosion damage, nor are they capable of hitting an actor to deal contact damage and _then_ explode normally but here's the thing: projectiles may not be able to collide with _actors_ while moving purely vertically, but they still collide with _planes_ and being under a floor or being above a ceiling counts as colliding with them so, if a romero head is positioned in such a way that its explosions will spawn below a floor or above a ceiling? the rockets will explode _using their normal death state,_ and thus will deal their normal splash damage to anything unfortunate enough to be in the blast radius. this also means that if an explosion spawns below a ceiling, but is carried into the ceiling by its upward momentum before it vanishes, it'll die and thus _reset the explosion animation,_ but this time as an actual damaging explosion - which, thanks to the aforementioned fact that splash damage doesn't bother checking vertical distances, is far more likely to kill something than you might first think
The "monsters can telefrag each other on MAP30" thing explains some odd behavior on MAP30 of the megawad "Epic 2," that being a stream of enemies teleporting in and instantly dying when you hit two switches. It wasn't some weird exploding barrel trick, just the engine doing what it was intended to do, albeit in an unintended way.
I genuinely love these analysis videos. They all have me learn something good and useful about doom. For instance, the armor video showed me that i shouldnt immediately pick up green armor under 100 percent. The rng one are also useful and interesting. Overall, all of your analysis videos helped me so much in playing some wads, and they are all interesting too.
Yay a new doom analysis video, this is so awesome because I love to be able to understand how a game works, and especially if it’s doom so thank you so much for making these videos and taking time to analyse the game. You’re the best 👍
Thank you so much for having visuals to explain this bosses code, I briefly understood what the cubespawner and cubetarget did but vaguely at best. You've mastered the ability of being informative while entertaining.
I just love how much effort, brain power and love is put into this vids and analysis. Decino is a very cool guy and a hidden pearl inside RUclips algorithm
I love these videos so much, I normally only understand a little bit of this stuff, as I'm not versed in coding amd stuff...but THIS is insane, I can't even fathom the complexity of this
I remember seeing 5:06 happen on EPIC2.wad’s MAP30 when you activate one of two buttons to get to the Icon of Sin. A bunch of enemies teleport in, but get telefragged, leaving only a single lousy imp to fight.
Also I believe the explosions from a dying Icon can only be seen if the Icon itself is facing South on a map. Any other direction and you'll get nothing. See: the Icon in TNT Evilution's "Last Call" map faces North, so upon death you'll hear the scream but get nothing.
Someone needs to spawn a -1 cube, and then we'll all place bets on what demon it spawns for 11.4 years - should give tons of time for people to get the pot nice and big. I vote it spawns an Arch Vile, for 100$ 🙃
4:40 i remember when i was a kid and saw my dad beat the game, he made a save file in the icon of sin after grabbing the rad suit, but whenever I tried to load it, it would crash, now i know why almost 20 years later
I lovw the fact that you and Dwars know each other. I'm especially drawn tp his channel because of Heretic and Hexen being the actual first FPS games I played before Doom. BTW, Excellent video as usual!
Hey decino, this video was featured in Cracked article titled "6 Gaming Secrets That Took Forever To Discover" - and they credited you with proper lowercase. :) _"The Icon of Sin is Doom 2's final boss. Its masterplan is literally giving birth to demons that'll hopefully prevent the main character from shooting it in its comically overexposed brains. (...) If you think Sin's strategy isn't flawed enough already, RUclipsr decino found out that, due to some very odd coding, one of the Sin's babies has a gestation period of nearly 11.6 years. So about 11.6 years way too late for anything other than a B-grade revenge-themed sequel."_
Wow Kotaku have done a small piece on the 12 years to spawn a demon part of your video linking this video on it :) really getting noticed out there Decino :D good work.
Well I said earlier we were expecting a yellow background. So much code for just one map, no wonder it came on 5 discs. I will watch this another few times over the next week until it all makes sense 👍 great work

it's worth noting that despite the fact that you can typically only damage the icon of sin with rockets, the romero head actor doesn't actually have any sort of damage immunity. instead, the head in d2m30 ( as well as many, _many_ map30s that follow ) is just too low to hit with most weapons. but, since splash damage only checks proximity on the xy axis, rockets are still able to damage it by hitting the wall behind it and catching it in their explosion. subsequently, ports like gzdoom which make splash damage use 3d collision detection have to "cheat" and ignore that added functionality _specifically for the romero head_ just to make sure that map30 doesn't _break_
also, the explosions from a dying romero hero _don't_ actually hurt ... under the conditions of a typical map30 setup, anyway. the S_BRAINEXPLODE states don't call A_Explode like the normal rocket death states, and while the spawned actors are 100% standard rockets forced into a non-standard state ( meaning, they're still projectiles - even though they're _visibly_ exploding, the rockets haven't actually _died_ ), actors only check to collide with other actors during P_XYMovement. which, as the name suggests, handles movement on the xy axis, not the z one. so, normally, they don't deal explosion damage, nor are they capable of hitting an actor to deal contact damage and _then_ explode normally
but here's the thing: projectiles may not be able to collide with _actors_ while moving purely vertically, but they still collide with _planes_
and being under a floor or being above a ceiling counts as colliding with them
so, if a romero head is positioned in such a way that its explosions will spawn below a floor or above a ceiling? the rockets will explode _using their normal death state,_ and thus will deal their normal splash damage to anything unfortunate enough to be in the blast radius. this also means that if an explosion spawns below a ceiling, but is carried into the ceiling by its upward momentum before it vanishes, it'll die and thus _reset the explosion animation,_ but this time as an actual damaging explosion - which, thanks to the aforementioned fact that splash damage doesn't bother checking vertical distances, is far more likely to kill something than you might first think

Overall, all of your analysis videos helped me so much in playing some wads, and they are all interesting too.
Would honestly love to see an "Ikcon of Simp" boss fight mod
Just go into a female Twitch streamer's chat and say something bad about her
Sounds like something that would fit into a mod like H-doom or the like. ;p
"Hey, that's pretty good!"
@Frax simp
I lost it at this part of the vid lol
Yay a new doom analysis video, this is so awesome because I love to be able to understand how a game works, and especially if it’s doom so thank you so much for making these videos and taking time to analyse the game. You’re the best 👍
Thank you so much for having visuals to explain this bosses code, I briefly understood what the cubespawner and cubetarget did but vaguely at best. You've mastered the ability of being informative while entertaining.
My God this is beautiful, thanks decino! Also.. "Spooky Bois" 😂 👌
I just love how much effort, brain power and love is put into this vids and analysis. Decino is a very cool guy and a hidden pearl inside RUclips algorithm
Game: how many explosions you want?
Icon of Sin: *Yes*
I love these videos so much, I normally only understand a little bit of this stuff, as I'm not versed in coding amd stuff...but THIS is insane, I can't even fathom the complexity of this
Decino, I really love your content. You're a very nice person. Keep doing what you enjoy, we enjoy it too :)
I remember seeing 5:06 happen on EPIC2.wad’s MAP30 when you activate one of two buttons to get to the Icon of Sin. A bunch of enemies teleport in, but get telefragged, leaving only a single lousy imp to fight.
"...oremoR nhoJ, em llik tsum uoy, emaG eht niw oT"
"To win the Game, you must kill me, John Romero..."
I happily went over 20 years without noticing that texture, it cannot be unseen
"What if the Icon Of Sin got stronger the more it stayed on earth?"
"Simple, the game crashes"
Also I believe the explosions from a dying Icon can only be seen if the Icon itself is facing South on a map. Any other direction and you'll get nothing.
See: the Icon in TNT Evilution's "Last Call" map faces North, so upon death you'll hear the scream but get nothing.
Thanks Decino. I always enjoy your content, wether it's a playthrough or an informative video :)
Someone needs to spawn a -1 cube, and then we'll all place bets on what demon it spawns for 11.4 years - should give tons of time for people to get the pot nice and big.
I vote it spawns an Arch Vile, for 100$ 🙃
Aw, sorry Decino, missed this upload somehow. These analysis videos are some of my favorite, keep 'em up DoomGod!
Fun fact:
The German Technology is The finest
Is Stroheim the best worst guy or the worst best guy
@@__-ix7qn Stroheim is best waifu
Bakamonoga
@@metagen77 such heresy being said. Speedwagon is best waifu, everyone knows that.

These yellow background videos are some of my favourite videos on RUclips, and I hope you don't run out of things to talk about in them any time soon
Oddly enough, I just killed the Icon of Sin in TNT Evilution about 35 minutes ago. What a coincidence!
4:40 i remember when i was a kid and saw my dad beat the game, he made a save file in the icon of sin after grabbing the rad suit, but whenever I tried to load it, it would crash, now i know why almost 20 years later
8:07 why
Use your imagination and suppose the gap is part of the wall that the Icon of Sin is inside. Problem fixed. No need to thank me.
Living Between Paychecks Kitchen I’ve been playing doom all my life and never noticed that.
I lovw the fact that you and Dwars know each other. I'm especially drawn tp his channel because of Heretic and Hexen being the actual first FPS games I played before Doom. BTW, Excellent video as usual!
7:43 that scream sounds painful
Sounds memey
The real surprise is that those are actually screams of pleasure from the source.
You are the DOOM MASTER! I love your videos!
Misheard Line:
EVAN DIED EAT EGGS THE MILK YUM YUM
1:03
Man, i sincerely hope you will never run out of topics related to doom. I love your vids so much.
No one has won the game cause John Romero is still alive
"To win my heart, you must subscribe to me, Decino." You're welcome.
Hey decino, this video was featured in Cracked article titled "6 Gaming Secrets That Took Forever To Discover" - and they credited you with proper lowercase. :)
_"The Icon of Sin is Doom 2's final boss. Its masterplan is literally giving birth to demons that'll hopefully prevent the main character from shooting it in its comically overexposed brains. (...) If you think Sin's strategy isn't flawed enough already, RUclipsr decino found out that, due to some very odd coding, one of the Sin's babies has a gestation period of nearly 11.6 years. So about 11.6 years way too late for anything other than a B-grade revenge-themed sequel."_
Cool, but Doomworld found it. Not me.
I just finished playing doom 2 the other day and really enjoyed it. Love your content!
I paused my black metal when I saw this notification. Priorities
What black metal were you listening to?
Arch Enemy's pretty good
@@voidghost4933 What about archvile
5:25 Amazing. Never found the answer to that question. Thanks, outstanding.
is it just me or there's a high pitch noise playing from the beginning of the video to around 2:22
Check the pinned comment.
@@decino Oh sorry haha, missed it! thanks
Wow Kotaku have done a small piece on the 12 years to spawn a demon part of your video linking this video on it :) really getting noticed out there Decino :D good work.
Plot twist: Decino's head is inside Romero's head
So you're saying that Romero has a pumpkin in his head?
Well I said earlier we were expecting a yellow background. So much code for just one map, no wonder it came on 5 discs. I will watch this another few times over the next week until it all makes sense 👍 great work
Fun fact: Icon of sin can sometimes change his voice when he says that message at the beginning (in unity version at least)
Finally, I've been waiting for so long for this video.
Long Live the Icon of Sin.
The Icon of Sin is actually John Romero's head?? Next thing you'll be telling me Super Mario Bros. 2 is actually Doki Doki Panic in Japan.
And then decino will explain to his audience what VHS tapes are and what they were used for.
You do a great job, thank you. Love this channel.
So this explains why I've been buying any random sigils I've come across for the last quarter of a century....
Oh well, money well spent *cackles in demon*.
Another helplessly nerdy and geeky video with need to know stuff about DooM.
And i love it!
"...oniceD ,em ot emoc tsum uoy ,sgnikrow renni eht wonk oT"
Great video.
Never was a big fan of this level, but that music though... still my favourite track in Doom 2
The high pitch sound at 1:27 is like a dog whistle, where’s it coming from
The background music. Check the pinned comment.
So glad I finally know what the Icon of Sin is saying. All those years of uncertainty, it was a nightmare!
1:10
What he really say:
To win the game you have to kill me John Romero.
No. He actually says "oremoR nhoJ em llik ot evah uoy emag eht niw oT"
DIOLOGISCH XD do you know how to take a joke?
@@pinkmanW1 Do you know how to take a meta-joke?
@@pinkmanW1 did I said that is not* funny?
That was fascinating. I love your work!
"To win my heart you must subscribe to me, decino."
5:16 Was that a Heretic/HeXen type of gibbing animation? I've never seen that in Doom.
It's a PrBoom+ easter egg I managed to capture. Happens rarely.
@@decino how interesting 🤔
@@decino Gives a better image of the archie that gibbed you
