📋 About This Mod
This mod applies many changes concerning how NPCs & creatures behave in the game on various circumstances. Greatest focus placed upon enemy combat patterns and detection system.
It is the result of a lot of tweaking, reading and testing in game. Also by having some experience with some modifications I did back in the day for Fallout 3.
-
[]Generic AI detection tweaks
[
]Effect of lighting conditions is now much more important. It will be the most critical factor on detection chance[]Adjusted the impact that sound and noises have on detection
[]NPC status (eg. just woke up, sitting etc) now affects its alertness
[]Player sneak skills now pose a smaller coefficient on successful stealth. Environmental conditions (ie. lighting / darkness) are more important now
[]Detection distance tweaked
[]Changes in various timers, eg. how long enemies will look / be alert, or search for you (increased all the more)
[]Stealth point system tweaks
[]AI visibility fov slightly reduced, from 190 to 170. I believe it was way too much
[]Patrolling / Sandboxing areas are expanded
[]Adjusted some combat tactics, such as how often AI should throw grenades or advance their cover etc.
