📋 About This Mod

This mod changes the settings of stealth and combat AI behavior. More than 40 parameters have been rebalanced in the Combat Search, Visibility and Sound Perception categories. Enemies are now very active when searching for the protagonist.

You are probably familiar with the situation when during the battle you could kill one of the enemies, then wait out the end of the alarm for a short time and all the NPCs quickly returned to their places of deployment as if nothing had happened before.

Now everything will be a little different. 

                                                                         War… War never changes.

This mod significantly reworks the settings of combat intelligence:

  • []enemies will hear the sounds of shooting and explosions at a considerable distance (this is especially noticeable indoors),

    []AI is searching for a longer time,

    []the search radius inside and outside buildings has been increased,

    []the visibility modifier has also been redesigned (now the light is your enemy, and the night is the perfect time for sabotage),

    []for realism, the angle of view of enemies is reduced to 142-148 degrees (default = 190),

    []for realism, penalty for stealth for wearing armor has also been changed to a lesser extent (together with a reduced NPC`s viewing angle you can more successfully inflict hidden attacks with melee weapons),

    []NPC sleep sensitivity has been significantly reduced. Sleeping NPCs will no longer wake up from your every movement.

    • []You can choose from 4 game profiles: Easy, Normal, Hard or Extreme. They differ in the level of AI sensitivity to your actions.

      []"New Detection" mod does not contain scripts, it just changes certain parameters of the vanilla game.

      []Tests were actively run in the following areas: Super-Duper Mart, Springvale School, metro tunnels and some open locations.

      []You can start using this mod at any time. You don't have to start a new game.

      []This mod has become part of the global rebalance mod - Simple Set Pack

    • For more spectacular integration, it is recommended to use this mod in combination with other mods and utilities (the list is published below).
