Yeah, you see, its already in Fallout 3 just not in the right place, and it doesnt have to be immediate but...
Situation: Raider party, me on hill, i open up a can of Heavy Weapons Guy and pour lead downhill.
Why cant they at least flee to cover?
Common sense doesn't play a part, its instinctual self-preservation.
There is a morale system in the game. I don't know how it works, so maybe a modder who knows can shed some light. I do know that if you bring a NPCs health down close to 0 and they can, they'll flee. I've also seen non-unjured NPCs flee when a large percentage of their spawn mates die. We also know of the companion "Nerve" trait. So there is a morale system in the game. What that system is programmed to recognize as contributing factors, I don't know, other than obviously NPC health. I suppose since this "Nerve" is probably a setting in the GECK, that maybe a modder will have more knowledge.
-Gunny out.
