Since I have so many failed demos recorded from speedrun attempts I figured I'd do the same as I did with UV difficulty and compile a video of some of the deaths. There are many more failed attempts than what is shown here (yes, even by the door on map 09). A lot more frequent than death are mistakes that doesn't kill me and cost time, and if the time loss is too big then I'll be too slow.
As this is single segment attempts, every death means I have to start from map 01 again.
Enjoy!
Some comments:
Spectres are a lot harder to see in CNDoom sourceport, they are easy to see in this video because the video is recorded while the demos are played back in PrBoom+.
Highest chance of getting killed are map 02 and 05, usually I don't keep demos that doesn't make it past map 05. So not too many interesting deaths to show for maps 02-04.
Only on map 21 and 28 have I never lost a run.
First death on map 06 in this video I didn't shoot because it moves the shotgunners around, and so when I did I lost a run because I got hit trying to skip the elevator.
Map 07 perfectly shows how projectiles are likely to go through walls on nightmare.
I die a lot on map 09 when I try to go through that door, even though I could use the elevator. In this route I skip the mega armor and pick it up on my way back, which saves a lot of time on the next maps by making them easier. If I take the elevator then I lose too much time so going through the door is the best option. More often than not I survive, but there's a good chance I'll just die.
On map 11 I end up getting killed next to the pain elemental after failing to jump down to the cacodemons. What happened there is that I go from moving forward to instantly moving backwards after colliding with the wall\pain elemental. Monsters can't push you without doing damage and I am holding move forward, so it should be impossible, but due to some weird stuff with the movement code this can happen and end a run. It is more common in some spots due to geometry and monsters, I've lost a run here 4 times to this.
On map 18 my inputs are identical every single time after I go through the teleporter. Due to randomness the results vary greatly, in these cases the outcome was death!
On map 20 the rocket somehow missed, I've never had the rocket go upwards and miss everything even when I practiced. There are just some weird things you can't prepare for.
Very likely to fail something on map 22 or 23.
On map 24 I failed to hit 3 inputs at the same time (I hit either turn left or strafe left a single frame too late). However, that should not have been a problem because my exact position should have allowed that to work. But because I managed to move very close to the wall (.00 coordinate, which was very unlikely to happen) it also failed. The second time I got hit by a lost soul, which will always cause the wallrun to fail.
Map 25, low on health or plasma on all of these attempts, which makes it hard to survive and forces stupid looking mistakes like killing myself with a rocket.
On map 27 you need the arch-vile to open the door, however there are some cases where he will get to the door and not open it. If this happens it takes around 12 seconds for him to get back and try again. There is nothing I can do about that, as it depends on the RNG index which is impossible to predict. In this case I needed that arch-vile to open the door and I would have a decent chance at sub 23 minutes, but a 12 second time loss would be impossible to make up. I knew the door was closed when I didn't hear him, but I couldn't afford to wait either so I went and looked and just ended the run there instead of playing it out.
First death on map 29 showed here I needed a good time, so I had to rush things (like the mancubus). The BFG on the first cacodemon missed by the smallest possible amount, the minimum amount of turn right I could do would have killed him. I've never had such a low health going into the next room so I missed the BFG when I had to go for the 25% health.
The second death on map 29 was really brutal, the time was good enough for under 23 minutes, assuming I didn't completely fail map 30, but I took a baron fireball and the hitscanners finished the job.
Failed twice on map 30, the first time was because I hit fire a frame too early. The second time I got hit by a revenant and I had no idea where my position on the platform was (with HUD I couldn't see the platform I was standing on at all), so my visual que for when to fire the rocket was off and so I fired too early.

This is a Tool-Assisted Speedrun!
Runner: Zero-Master
Date: 2023-10-03
IWAD: Doom2.wad
Category: UV Stroller TAS
Map: 1-30
Source Port: DSDA-Doom v0.26.2
Time: 1:16:58
Description:
Have you ever wondered if you could simply walk into map 30 and destroy the icon of sin, all while never harming a monster? Well, wonder no more as Ive yet again wasted my time trying to dodge projectiles + lots of hitscanners that are directly in front of me and applied the Arch-Vile Space Launch Program.
The stroller category is walk only, no strafing and pacifist, I also try to take damage as few times as possible.
I take damage on 5 levels:
Map 06: Impossible to reach the switch that lowers blue key elevator without damage boost, no invulnerability available either.
Map 25: Damage floor is too long after mega sphere room. The damage floor leading to the center area can be avoided by building momentum against a monster and running inside the bloodfall area, but would require a lot of work to do. No radsuit or invulnerability available.
Map 26: Damage floor is too long again after red key door, could avoid it on the way back though. Rad suit is available on the level, but is also impossible to reach without taking damage from the floor.
Map 29: Impossible to get past the 3 barriers near the end without a damage boost.
Map 30: Only level damage from monsters is required.
Tools used: 2xIDDT, frame by frame building, rewinding and segmenting, slow-motion (mostly 35% and 50%), coordinates and disabled pain palettte. Valid inputs and pacifist is verified by the source port.
Also several times I have probably been saved by the blockmap bug.
Thanks to Kraflab for DSDA-Doom and Napsalm for the HUD settings.
Map comments:
Map 01: Easy enough.
Map 02: Hitscan everywhere, fortunately its not too bad as they also infight easily.
Map 03: Blue key section was rough, not much room to move around.
Map 04: Didnt expect the imps at blue key being so annoying to get past.
Map 07: Switch press trick to exit immediately.
Map 09: This level doesnt look that bad oh boy, what a nightmare this one was. The moment I got to the rad suit I realized Ive messed up bad thinking this would be simple. Getting from the switch to the platform in time is really close with no monsters around, but here theres lots of monsters with little opportunity to cause infighting. Massive amount of work manipulating the monsters to somehow give me enough space to make both platforms in time.
Map 11: Another level I underestimated, the start is really rough, especially the arachnotrons as their projectiles are so quick. Then I discovered that the spectres are actually stuck by red key bridge switch, but fortunately it doesnt take too much effort to clear them with infighting.
Map 14: This map seems quite difficult, but I got past everything rather quickly.
Map 15: Easier to go with the secret exit here.
Map 31: Decided I might as well include map 32 this time.
Map 17: I knew this level was going to be rough, the start went ok, but the worst part is beyond the yellow key barrier. The 2 jumps you have to make here are extremely precise, if they were 0.5 units longer then they would have been impossible without a damage boost. Lots more infighting and I decided to take a couple of cacodemons with me to try and deal with the arachnotron up top.
Map 20: Also underestimated this one, the hitscanners after the teleporter were awful to deal with. Fortunately I could activate the teleporter elevator before going through, if not I would have needed to drag a cacodemon all the way to the tower to clear them out first.
Map 22: This one was easier than expected, spectres provided good cover from all the chaingunners when they infight while the revenant dealt with the rest. Didnt need to kill the chaingunner at red key, but I wasnt sure if I was returning the same way I came in.
Map 23: Easy, unfortunately 1 barrel was harmed in the making of this demo.
Map 24: Spent probably 10 minutes thinking this level was impossible to do without taking damage, just completely forgot that there is a normal route that allows you to avoid the damage floors. Also brought a lost soul with me into the red key room in case it was easier to activate a linedef to lower the platform.
Map 30: Much easier to get the arch-viles this time, lots of rewind just before the spawn cube + using the automap to easily confirm what monster spawned made it a much smoother. What was not easier was exiting the level. Without running you wouldnt be able to stand on the elevator for long enough on the way up as that was barely possible with normal movement speed. So here I have to launch myself off from the second level and somehow be able to enter the hole while having enough arch-viles attacking me afterwards. Took a few hours to get 33 viles (3 more than last time) and clear out the monsters to make the path clear, then several more hours before I finally managed to make it work. By far the hardest level.")

Who needs Quake duel when you have buffed marauders.
Ive had a few requests to do the updated the holt slayer gate, its not interesting enough to be worth to upload was my thoughts, so why not make it interesting. There was no doubt the original one was too easy, and I have heard some rumours that this new one is too difficult so its going to get nerfed. No idea if thats true, but in that case I figured Id do this before its too late. (edit: this gate is now easier in the current patch of doom eternal.)
ai_haste_overriderate 2 = double movement and attack speed.
No idea how many times I should have died here... or how many times I actually died attempting this.
Blood maykrs at double speed is probably the most bullshit thing I have ever seen in doom eternal so far. Carcasses that respawn constantly is not too far behind. And of course, a possessed marauder, where you have absolutely no idea when hes going to attack. I dont think Ive been bullied this much by an AI since Xan in unreal tournament some 20 years ago. I kind of forgot about the second marauder spawn, I think a carcass shield saved me from him, so theres that :)
Enjoy.")

This is a Tool-Assisted Speedrun!
Runner: Zero-Master
Date: 2021-06-28
IWAD: Doom.wad
Category: No Monsters 4-Player Coop TAS
Map: E4M6
Source Port (demo): XDRE v2.21
Source Port (video): PrBoom-Plus v2.5.1.5
Time: 0:42
Description:
For E4M6: Against Thee Wickedly you are required to kill a cyberdemon in order to finish the level, this means that a no monsters playthrough should be impossible since there is no cyberdemon to open up the pillars blocking the exit. However, there does exist a deathmatch spawn room where there exists a switch that can open the exit, so perhaps there is something we can do.
E4M6 nomo coop tas is probably not the most interesting thing in the world, but this level has never been done without monsters and it does two void glides in mid-air, which is a rather absurd trick thats also never been done before. To finish it off theres a rocket boost + BFG boost to access an area in order to activate a switch through a wall allowing another player to open the exit.
There is no air control in doom, and so there should be no way to create momentum mid air with exception of damage boosts. Yet doomguy manages to increase momentum to go through the wall anyways. The explanation for this is complicated, so Ill leave it out, but this took many hours of throwing doomguy at the wall and its one of the most difficult void glides Ive done.
So overall its pretty crazy that this was possible in the end.
A few times I punch another player, this was supposed to be used for activating switch to open exit area directly, but it turns out it didnt work even though I expected it to. You might wonder why punching another player helps activating a switch... well hopefully I can find a use for it sometime and Ill explain it then.
What the players do:
Player1: Get rocket launcher, open cyberdemon area, get invulnerability, void glide and open a deathmatch door for Player2:
Player2: Get red key, use red key switch to open up path to invulnerability and BFG, activate switch to open exit area and exit.
Player3: Get blue key, activate blue key switch, trigger linedef for teleport to lava section, use infinite height to block players next to the void entrance.
Player4: Get soulsphere, get rocket launcher, get BFG, void glide and boost player 1 using a BFG.
1-Player and/or non-TAS is not possible from my current knowledge unfortunately, though this could have been done with 3-Players.
Thanks for watching!")

Im sure everyone expected this.
Okuplok Slaughter Map: https://doomwiki.org/wiki/Okuplok_Slaughter_Map
UV-Fast: All kills and all secrets with -fast parameter (https://doomwiki.org/wiki/Fast_monsters)
No hit aka Almost Reality: Only damage taken is from unavoidable damaging floors.
TAS: Tool-Assisted Speedrun
Something a little bit out of the ordinary from me, but not quite brutal doom levels of weird. Creating a demo like this was basically impossible with the previous tools available, because frequent use of segmenting is necessary, and for long levels with a lot of monsters the load times get extremely tedious. However, recent improvements to segmenting has made stupid things like this possible.
I took damage at 2 points from damaging floors, first at 46:27, maybe I could have avoided it with some perfect timing, doesnt matter as theres another point at 1:42:25 where theres absolutely no way to avoid the damage. Obviously no IDDQD cheat is used, whenever I got hit I would simply re do it until I didnt get hit.
Nightmare is probably impossible with TAS, I dont think theres a possibility to get past the hell knights at 1:50:00 because of respawn. This map uses -complevel 9 or boom, which has a different respawn mechanic, in vanilla a monster will not respawn if its starting place is blocked by another monster. In boom however the monster can spawn on top of another monster causing them both to get stuck. So you have a massive wall of health you need to get through both ways with no way to move around it. (edit: actually I have an idea that might work, but I have no plans of actually trying it.)

The midi in oku2v31.wad got copyrighted, so I tried to replace it with the same midi that azu used in his UV-Max TAS. Of course youtubes copyright detection is complete trash so that one got falsely copyright claimed by AdRev Publishing, nice scam. Thankfully KoD has several other great midis, so hopefully this will do.
Thanks for watching.
FAQ:
You got hit!: What happens when you get hit? Thats right, you take damage, which only happened twice on damaging floor. This alone proves that I didnt get hit, but what if I modified the game to take 0 damage when hit or edited the video? Well in that case you can take the demo file where all my inputs are stored and play it back for yourself! It would be completely impossible for me to cheat like that as it can be easily checked by anyone. As for IDDQD its impossible to include it in a demo and it would have been extremely obvious if I actually did get hit. Its also possible to see every projectile from a free camera view when playing the demo, obviously that isnt necessary as the game tells you if you got hit or not.
You cheated, this isnt real: No shit, I have TAS in the video title, I have This is a Tool-Assisted Speedrun in the video description, what could that possibly mean? At no point have I ever claimed to dodge 10000s of projectiles in real time for 3 hours straight in a single segment, its literally impossible to reach the mastermind at the start doing that. So what does TAS mean? In this case the main feature that is used to achieve this is something called rewind or segmenting, and as I explained, whenever I take a hit I simply go back until I didnt take a hit and try again. This is incredibly easy to do. Take damage - rewind back a second - try something else - make progress or repeat until progress is made.
Why didnt the hit register??: Sprite size does not equal hitbox. Mancubus projectiles are much larger than their hitbox, so even if it looks like I should have gotten hit then that doesnt make it so.
Claiming someone is cheating in a TAS is incredibly dumb, a TAS would be a cheated run if there is no mention of TAS being used. So TAS is using features that would otherwise be considered cheating, so essentially its like saying: Youre cheating in this run which you are saying is intentionally cheated. However its is and has always been clearly labelled as a TAS, it would actually take a lot more effort to cheat by video editing or modifying the game etc.")
![Doom Eternal - Cultist Base Master Level [Nightmare][AI_Haste 2]](https://i.ytimg.com/vi/we-LOXy82ms/hqdefault.jpg "Doom Eternal - Cultist Base Master Level [Nightmare][AI_Haste 2]
This is cultist base master level on nightmare difficulty with the following console command:
ai_haste_overriderate 2
I dont know exactly what it does, but as you can tell the gameplay is a little bit different :) (I guess since its not too obvious, it doubles demon movement speed and attack speed/rate, no idea if it does anything else, and it definitely doesnt affect the slayer and it doesnt affect projectile speed, but theres a command for that as well).
Ive played with this setting before, originially I was planning to do the entire campaign with it about 1-2 months after the game released, but it was too exhausting so I gave up on it. I only did a couple of attempts and my only attempt that got past like the first level died at the end of ARC Complex to the marauder after I missed the ice bomb glitch. At 6:15 you can see the only marauder fight in this master level, its a lot easier when you have space to move around, unlike the end of ARC which is quite brutal in a straight up fight. The hardest part of the campaign itself is actually the gladiator, and marauders in general are difficult after the ice bomb fix.
Ive also played this master level with this setting before, but that was a few months ago now, usually I died a few times then, especially in the pit. This was actually my first attempt at recording a deathless playthrough, so thats fortunate.
This might be unexpected, but the most dangerous demon on this setting might just be the hell knight. An absolute terror because of its ability to cover the distance quickly and annihilate you immediately, and is therefore always the first priority to kill.
Thanks for watching.")
