Are you tired of scavs being utterly pointless after level 20? This mod is probably for you then.

Because all of the AI will level with you, they’ll all start wearing gearing that gets better as you get better. Bosses and their guards will always have decent loadouts. Scavs will actually wear the gear they have been scavenging (sometimes). What the hell is the purpose of scavs outside the early game? Now they have a purpose. Maybe they’ll spawn with armour worth yoinking the plates out of? Maybe they’ll spawn with weapons that have useful attachments for you! Who knows! That’s for you to try this mod and find out!

This gives you a reason to actually check your kills and maybe you’ll find something shiny.

All AI have their loadouts adjusted with this mod. Not just scavs. Not just PMCs. All of them.

Bosses still use their vanilla equipment, but have had tweaks to their ammo pools, and available attachments on weapon/gear.

Please review all of the mod page!


Do not use this with another progression mod.

FEATURES

Features

This list is not even close to encompassing everything that APBS can do, or what you can change!

  • Configuration Web App that has 125+ settings.
    • Chances are, if you want to change something - it’s available. If not, ask for it and maybe it’ll be added.
    • Please, actually look at the config - it covers so much more than the features listed here.
  • All AI will level with you.
  • All AI have a tiering system.
  • All AI weapons have individual attachment chances in each tier.
    • Snipers, Marksman Rifles, and Carbines have scopes more often.
    • Assault Rifles have foregrips, stocks, muzzles more often. (etc etc etc)
  • All AI will use MODDED weapons, equipment, and clothing that you have installed.
    • Must be enabled in the config - Not all mods are compatible, no support granted
    • If you have Pack’N’Strap - AI will have the belts in their Armband slot!
    • If you have Realism - You can enable adding gas masks to Bots if you play with Hazard Zones
  • All PMCs will use weapons/equipment for kill quests that require specific things (v1.7.0+)
    • 20 quests are currently available for them to choose from, they must be on an available map and within level range to being “assigned” a quest .
    • Questing Bots is not required for this feature, it’s completely independent.
  • All AI pocket/rig/backpack loot has been adjusted.
    • Balancing - no more ammo box spam on PMCs.
    • Whitelists - nobody can use impact grenades except PMCs, and they must be of a higher level to use them.
  • All AI Weapon Durability has been adjusted and balanced.
  • All AI medical/food/drink items may appear to be used.
  • All AI will randomly choose to use different ammunition in their additional mags.
    • Maybe that SR-25 spawned with M80, but perhaps one of their mags has M62 in it…or BCP. Who knows!
  • All AI can use different size magazines based on your configuration.
    • If they spawn with 60 rounders, they won’t have like 5 of them - they are limited to 2.
  • Your Player Scav will have gear generated based on your PMC level. Maybe you’ll get a decent gun.
  • USEC spawn with weapons that you would expect from non-Russian forces.
  • BEAR spawn with weapons that you would expect from Russian forces.
  • Per map weapon choices for AI? You got it! Factory is mostly short range, but Woods is mostly long range!
  • AI will used NVGs if it’s night, and they have a helmet supporting NVGs. They will not wear them during the day.
  • Scavs have a low chance to use weapons and equipment from the same tier PMC (or lower) as them.
  • Scavs weapon attachments and ammo will always be more basic, never meta.
  • Guards/Raiders/Rogues are beefed up a bit, they should be dangerous instead of a cake-walk.
  • All tiering and item weights are handmade and subject to change.
    • What is tiered?
      • Weapons!
      • Equipment!
      • PMC Clothing!
      • Attachments!
      • Ammo!
    • This is not based on “loadouts” or “kits”, nor traders, nor anything else other progression mods do.
    • It’s just based on tiers (by level), and completely random within those tiers.
  • Custom Presets (v1.1.0+) can be created, and shared between users. Make your own progression!
    • Please see “Presets” tab for information.
    • EVERYTHING that APBS does with AI loadouts and equipment, you can also do.
      • Change their equipment pools? Check!
      • Change their ammo pools? Check!
      • Change the CHANCE of a specific attachment on a specific class of weapons? Check!
      • APBS is yours to create and customize. Share your preset with users. Laugh at them getting wiped by your gigachad scavs. Do what you want.
TIERS

Tiering System

  • All tiers are based on YOUR PMC level.
  • All of these deltas can be changed in the configuration. If you want more variance, then configure it! If you want less, configure it!
    • You can also configure custom level deltas for Scavs separately, if you so wanted.
    • The configuration values for custom deltas are done per tier, so you need to set each of them - the “Tier” is based on YOUR PMC level.
    • If you want AI to be any level possible, set each custom level delta in the config to 79 levels below you and 79 levels above you.
  • Min Level Delta: The number of levels BELOW your player level the AI can spawn
  • Max Level Delta: The number of levels ABOVE your player level the AI can spawn
    • Example #2: Player Level 27. Tier 3. AI will spawn between level 12 & level 34.
    • Example #1: Player Level 32. Tier 4. AI will spawn between level 12 & level 42.
    • Example #3: Player Level 48. Tier 5. AI will spawn between level 18 & level 63.
CONFIG

Configuration

Config App is gone, to edit the configuration run your server after installing and go to:

  • https://127.0.0.1:6969/progressivebotsystem/

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.

ALTERNATIVE MODS

Alternative Mods

I know this mod won’t be for everyone, and the intention is to provide an alternative progression mod. It’s a type of mod that I wanted to take on because progression mods are a different type of hell to develop and implement.

The scope and end-goal of this mod is my vision of progression for SPT. It may not match what you want or enjoy.

If you don’t like it - I won’t be offended and you don’t have to use it.

I would suggest trying any of the following alternative progression mods if you do not like APBS:

ALP - ALGORITHMIC LEVEL PROGRESSION
VALENS-PROGRESSION

SPT REALISM MOD

ANDERN

If you enjoy my work - you can buy me a coffee~

Hi @Acidphantasm, Big thnaks for your work (i mean all the work, i use everyone of your mods) I have a little thing to demand, if you are ok with it, i wan’t sure where to demand it so i put it right here.. Can you add a parameter for manually add specific loot (and a chance of it occur obviously) into inventory of AI ?… before i use your mod, this part of the thing was generated by Andern, and my AI was able to loot GP coins, and now i’m habit with that and thre is never a chance in your way to have that specific loot… (i mean there is a chance but maybe 1 of 1000 or less… completly random thing)

I want to thank you again; it’s thanks to people like you that we’re on SPT.

Hello! I have a question. How do I navigate the config for the level tier presets? By which I mean when T1 goes to T2 at which level that transition happens, I’d like to config it. Also is there a means I can reference to help also navigate the other files as well? I apologize if my questions seem out of place. I just want to make sure I don’t screw anything up when adjusting things. Thank you!

acid is a saint for answering issues that have nothing to do with this mod lol

wttbtt *

as I’ve experienced issues and seen some comments and confusion regarding this, the peculiar scav behavior some have associated with the mod is a result of the currently active halloween event and does not have anything to do with the mod - as it just so happens, these mods were updated for SPT 4.0.2, very close to when the event started, leading to them being installed along with the event AI changes and creating a bit of a coincidence. if you want to, you can turn off either events themselves or just the AI changes for the event using SVM
