📋 About This Mod

Fallout 4 AI Overhaul

Not a combat AI mod.

Getting tired of how dull the NPCs daily lives are? Why doesn’t anyone have any sense of self-preservation? Are they even real humans when they just ignore rad storms while the player gets their DNA blasted?

 "F4AIO" is a quest system that incorporates AI adjustments to the generic NPCs populating Diamond City and Goodneighbor. This makes them react to harsh weather, become a bit livelier and unpredictable in their environments and react accordingly to danger. They may even use toilets for 100^10% Immersion

What it does?

  • []Incorporates AI enhancements in the form of a single universal quest system to generic NPCs.

    []Adds new custom markers and idles inside Diamond City, Goodneighbor and interiors shops, bars and public areas.

    []Changes core game settings to NPC Social & Sandbox AI

    []Directly reworks AI package data to a custom AI Overhaul template for NPCs

  • Quest related NPC's and Guards are left alone. Merchants are excluded from weather behavior.

    NPCs now have less static schedules from a complete rework of the default AI packages that is complimented by the dynamic quest AI. They are now much more unpredictable in their daily lives and act more dynamically with the world.

    Idle Markers:

    More markers have been added in towns and public area interiors only. Some are made custom for dynamic use. There are also sleep areas for NPCs without beds to simply lay down.

    Weather reaction:

    During harsh weather conditions NPCs without jobs will find cover. Most NPC's immediately seek shelter in Rad storms.

    Society & Survival:

    The main towns are distinct on how NPCs react to the world. Diamond City residents are less likely to engage in a community wide effort to abolish a single rad roach, whereas the people of Goodneighbor are more likely to help each other out. They will either run home to avoid danger or from you if you attack them.

    Other NPC's:

    Any mod added NPC's will follow the basic sandbox & weather AI while conditions are met.

    Mod added NPC combat reaction will only trigger if they have the Citizen Class inside of those city spaces.

    Performance?

    -NO permanent alias' in use & No scripts.

    -The mod accounts for only 10 additional NPCs which should be enough for mods that add more NPCs while not being overkill on me
