To start - I well know realities of deathworld, I even played overloaded deathworld on desert with 30% biters price. I also played some rapant games (though I never played as long as today). Today I got annoyed, because biters don't seem to care in the slightest about amount of pollution that I'm producing. They tripled or even quadripled in numbers after I stopped polluting their nests for over one hour. I see in statistics that their nests no longer absorb pollution, so why they keep attacking? Do biters only care about time that passed in save? What if I got map without any oil and I need to approach it slowly?

I know about AI modes and I know about "onslought" or whatever it is called, but they were not absorbing a lot of pollution since a long time, they shouldn't have "points/credits" to create such a ridiculous attack.

Vanilla factorio with 30% biter cost was less ridiculous, cause if you pollute a lot, they will destroy you, but if you slow down, they will slow down too. In gamethrough with this mod (60% biters cost, so even softer than deathworld. I was not going all-in) no matter what I do, they just increase and increase pressure, they never slow down, is that supposed to happen? That's not fun. I got destroyed by map that didn't gave me any oil (I only just found it after bypassing many biter nests) I was playing slowly and reducing pollution, but biters kept increasing pressure all the time, no matter if I research if I don't research, if I polute, if I don't, they don't care. They seem to care only about time passed (and I set biter evolution time factor to 0, I only complain about attack amount not being dependent on pollution, evolution worked fine)

I can not find option to disable biter strength dependent on time. I want it to be dependent mostly on pollution! Player proximity attacks are fine (though annoying, I was unable to explore and search for oil!) siege AI is fine (nice mechanic), but increasing pressure just because x time has passed is ridiculous.

Maybe there's option to debug biter "points" stored? I know there's debug of AI-state, but I want to know how many points they have at what moment, because I completely don't understand their behavior in this game and miss-understanding leads to frustration.

I was having fun with difficulty level, it was intense, but then last 2 attacks were just 3 -4 times out of proportion I just completely don't understand their proportion even if considering AI-state when they go "all in"

On average, Rampant Fixed creates approximately one squad per minute on the deathworld, spending AI points on this. The generation of points depends on evolution, the total number of nests (slightly) and the presence of nests nearby (significantly). The size of the squad depends on the evolution and presence of biters. So, for example, at 30% the average squad size for AI points is approximately 15 biters. At 50% - 28 biters. 100% - 70 biters

Also, action points are given to the AI when destroying worms and nests. That is, if you go to war, then you should take care of protecting the base

Pollution attacks occur separately. At the beginning of the game, biters cost about 2 times more. Approximately 40% evo - the same. Further, the power of attacks per unit of pollution becomes stronger than the standard one. Thus, it is highly recommended to get the pollution under control at 40-50%evo, otherwise you will be killed by the standard AI.

On average, with careful play, "Rampant Fixed" on the deathworld is easier up to 30% of the evolution and more difficult after that. And the difficult continues to increase.

A "green base" is a necessary but not sufficient condition for victory. There will be attacks in any case, although if the nests are outside the polluted zone and far away, then their strength is much weaker. Therefore, you will have to defend the captured space and ensure the supply of ammunition

If you want to see the total number of action points, turn on the map setting "DEBUG: Print Temperament Changes to Chat"
If you want to see the sqaad being created, turn on the setting "AI: Print Point Spending to Chat"
If you want to remove AI points generation from time, set the "AI: Action points scaling" setting to zero
If you want to reduce the generation of AI points when destroying nests, then set the "AI: Difficulty" setting to "easy". It is impossible to completely remove the generation of action points when destroying nests, so be prepared for counterattacks when attacking nests

Overall, playing against Rampant Fixed is similar to playing against biters on a vanilla standard world. Ideally, you need to clear the area where there will be pollution and the necessary resources from biters as early as possible. With one significant difference - the need for thoughtful defense, which will be needed anyway

For example, here is my typical death world from Rampant Fixed. As you can see, at 30% of evolution the perimeter is not needed.
But later the lack of perimeter will be punished.

Revange for killing their bases must be what caused my demise! Thanks for detailed response, I think I neglected killing bases near my walls regurarly (so their "proximity attacks" became more frequent - even if I had 0 pollution touching them)

What have to be destroying factor for me was that I killed few nests on my way to oil (they attacked with electric+suicide biters in revange) and then I decided to fix hole in my wall and I destroyed few suicide biter nests, which caused even bigger regenerative+sapper wave which destroyed me.

And also - in my case - biters indeed didn't cared about my pollution savings in the slightest, because other factors contributed more to their attacks.

Thank you for the answer!

Man this mod rules
