What does Chemfluence do?
Chemfluence is a dynamic Fallout 4 mod that revolutionizes combat interactions. This innovative modification enhances AI behavior by integrating two key factors: chem usage and weapon choice. With Chemfluence, AI characters not only respond to chem consumption with distinct combat strategies but also adapt their tactics based on the weapons they wield. Ranged weapon users maintain distance, shotgun enthusiasts close in for impactful shots, and melee combatants showcase various behaviors like flanking, aggressive assaults, or skillful defensive maneuvers. This mod elevates combat realism and unpredictability, making each engagement a unique and strategic experience.
Combat Behavior by weapon
Chemfluence introduces several new combat styles to NPCs, which are randomly selected per NPC and change depending on chem usage.
Melee Weapons
4 new combat behaviors. This will spice up your melee combat experience, as different raiders, can have different behaviors. Some like more to block. Others are more aggressive. Some like to flank before they attack.
Ranged Weapons
6 new combat behaviors. They have different ranges they prefer. Some NPCs like to get closer. Some may stay further away and prefer to snipe you. Others may don't care about their bullets and shoot more aggressiv but less accurate, while others take their time for more precise shots at you.
