Doom II: Nuts 100% Kills - 85 Revenants vs 850 Cyberdemons [TAS]

This is a Tool-Assisted Speedrun!
"Nuts by B.P.R.D contains 10617 monsters in two rooms and is almost unplayable as a result. It is featured in Doomworld’s Top 10 Infamous WADs and also in their Top 100 Most Memorable Maps, placing 4th."
Pain. I started working on this 4 months ago...
This video is in 2 segments for reasons explained below, the second part starts at 17:16.
This is the first true UV-Max completion of this level, where 100% kills and 100% secrets (0 out of 0 in this case) is achieved. The issue with maxing this level is that even with really good infighting and perfect ammo management you are left with roughly 800 cyberdemons at 4000 health each and nothing besides your fists, which deals 2-20 damage per hit, to kill them with.
The monsters can do some damage to the cyberdemons through infighting, most notably the arch-viles, but eventually they get destroyed by the splash damage.
Any monster on the upper area that attacks the cyberdemons are also quickly killed off, so there is only one solution: gather up enough homing revenant rockets to tear through all the cyberdemons. So how many do we need exactly? 850 cyberdemon at 4000 health where revenants rockets do an average of 45 damage, that means we need to simply gather up at least 70000 rockets, great! ... There's just one more problem, while this is an incredibly easy task to do, it should take roughly 5 hours of circling revenants before you've got enough.
5 hours isn't too bad, sure, but that's in game time, unfortunately the game runs a bit slower once the rockets start to pile up... to the point where you are moving 0.5 seconds every minute!
So in real time it takes about 23 days to gather the rockets, which would be extremely boring to do. Luckily the upper area is really large, so what I did was take a segment where I circle the area, copy the inputs and insert them multiple times into the demo so that it's nearly 6 hours long and then simply let my laptop play through the demo for 23 days before I then take control! So nobody, including myself, have actually seen what happens between 30 minutes and 340 minutes.
Then of course the fun part begins, where you are moving 4 frames every 14 seconds to guide the rockets to the cyberdemons. There's a few places where I do some weird things like take damage for no reason, which is because of just horrible controls (I can't even move backwards) and doing it over again takes at least 30 minutes, so I left it like that. I would have tried to make it a bit better looking, but putting in effort to do that would have driven me mad, so it'll have to do. It took roughly 20 hours to do 10 minutes, needless to say that is just an awful experience. Then there was another 25 days or so of waiting to create the video.
At the start you have to help the revenants out by killing the barons, as the barons would win easily. The part between roughly 14:55 to 16:10 is repeated/copied until I have enough projectiles.
This can be done non-TAS, you just need an actual super computer optimized to play doom and about 6 hours.
What an absolute waste of my time this has been, hopefully you'll enjoy this more than I did.

[@killian_palmer]

Congrats on this achievement! In early 2021 I was also working on figuring out a possible strategy for 100% TASing this map, but didn't get very far. I came to the same conclusion: The given ammo isn't nearly enough for killing everything, and causing infighting between the cyberdemons and other monsters realistically isn't going to be feasable without them being killed off immediately. The only renewable source of damage for killing cyberdemons are the revenant fireballs. But I didn't do the math to figure out how incredibly long it would take to generate 7k fireballs, lol. I never got far enough to make a repeatable input sequence and looping it; I got a little distracted by tinkering with XDRE (adding a command to output the number of fireballs; making the in-game minimap's grid match the blockmap exactly; creating a better GUI; etc.). And then I forgot about the whole thing entirely. I'm glad you went though with it, even if it took you ages to complete! Side note: For an Any% TAS, I was trying to better understand the all-ghosts effect, which can be triggered very easily (even accidentally) on this map. I spent a while thinking about how one might trigger the intercepts overflow in such a way, that the resulting 1-width blockmap overlays the exit switch, in theory making it possible to run through walls and enemies outside the blockmap but still finish the level. Or, perhaps, any way to trigger a second intercept overflow when at the exit switch to "uncorrupt" memory. I believe my conclusions were that moving a 1-width blockmap to the exit switch is impossible due to the X,Y coordinate values not having enough range, but I might be misremembering. I didn't go any further, besides some in-game experimentation and code reading.

[@iennefaLsh]

Sort of like programming a robot to play the game, except the player plays the game themselves. Instead of lines of code, it's like trying to play the game literally as perfect as possible. If there's a mistake, immediately load a save file. Need frame-perfect inputs? Literally play frame-by-frame or just slow it down a notch. In TAS, it's all fair game as long as no code modification or cheat codes are involved.

The backstory of how this run was created is fascinating. Apparently, it took over a month to do this video because of the slow frame rate, using programming and a lot of ZM's labour to direct the rockets -- which is now reduced to 30 minutes of gameplay. If 30 min seems long to you, imagine the tedium of making it! I am still not 100% sure what's happening but it seems to be a way to bring about friendly fire from the revenants and cyberdemons.

Revenants fire a honing missile 30% of the time and you can use them to cause other monsters to infight or kill them. This is 70k Revenant missiles all in one, so many in fact it doesn't even render the sprite of the missiles, so it looks invisible.
