SPT 4.0.3 Compatible
Configurable spawn mod, allows waves / starting PMCs / boss chances / progressive boss chances. ABPS will always try to keep your raids full and different each time.
Please review the configuration app, as the default configuration is built the way it is because I enjoy it like this. All options in the configuration app have tooltips, please read them. You can adjust it freely to your liking. The configuration comes with starting PMCs only, and no additional PMC spawns - all bosses are set the same as vanilla defaults in SPT. The default Scav configuration will attempt to keep the map at near caps for the map at all times.
Both PMC & Scav spawning has been built to only spawn a specific distance from players, and any other bots to spread them around the map a bit. The distance values for this are configurable in F12 - but be careful not to go overboard making them as high as you can as that may delay spawns.
Support for Legion/Punisher is automatic, but ABPS allows those mods to control their bosses. There is no special configuration for them in this mod.
ABPS is also Fika compatible as far as I have tested, only the hosts settings will be used.
Do not use this with another spawn mod.
This mod is still in active development. It may be missing features or configuration options you may want.

Demonstration Video (yoink):

Config App is gone, to edit the configuration run your server after installing and go to:
https://127.0.0.1:6969/botplacementsystem/
All configs can be updated and edited while the server is running - provided nobody is in raid.
If you are using Fika then put the appropriate IP and port instead.
Known Issues
- AI hostility may be fucky. When I’m bored of Dune: Awakening I’ll be working on it.
- Spawning too many PMCs in a wave will probably cause issues with those bots
If you enjoy my work - you can buy me a coffee~

Special thank you to CWX for doing an initial port of ABPS to SPT 4.0 - I took their foundation, expanded it, and updated logic where I felt necessary. Without CWX doing this, ABPS would not be updated today.
I tested this with SAIN and 60+ PMCs on Customs in a single raid and never saw any problems, but there was a LOT of fighting constantly.

umm what about web config with fika? hm
May I ask what happened to the old Config menu?
Hey again, is there a way to change only the “custom timers” settings for factory/labs/labyrinth ? I find the spawning to be fine on most maps, but on factory there is just not enough time between all the scavs throwing themselves at you. I had the same issue in 3.11 SPT on labs, but there I just tweaked the raider spawn timer as it’s set to -1 by default which means they just immediately spawn more after killing them.
Testing to confirm my configuration and applying only this mod, performance drops 20% from 60 to 40 FPS, limiting the number of bots on the map to 10—even fewer than the default SPT version. However, it’s a good mod for limiting the number of bots, especially for PCs with plenty of FPS.thans
most pmcs are still friendly to eachother unfortunately. i constantly see them all walking next to eachother and only fighting me with the latest version and group chance 0.
did anyone know how to turn the boss rotation on maps back on with this mod? with htis mod no boss roation
what was wrong with the config app?
uh.. hello is there a way to change bot spawn distance from player? i literally died after spawn at 00:00:05 lol
Is there a way to reduce scavs? I tried jiggling with the settings but i am guessing these apply only to factory etc? Since i installed this mod Scav spawns are out of control i end up the raid and i see 10 scavs on raid and it kinda being heavy on my FPS since i run the server on my pc. Thanks for this mod though.
Getting raiders on labs at raid starts, not sure this is intended? Haven’t played in quite some time
