Lynch’s NPCs Essentials is a comprehensive AI behavior enhancement addon designed to upgrade several of Garry’s Mod default Half-Life 2 NPCs. Its goal is to improve combat readability, make NPC battles more entertaining to watch, and add subtle but impactful quality-of-life improvements across various NPC types - all while preserving performance.

This addon features individual behavior upgrades, logic-based decision-making, improved reactions, and fully configurable systems through ConVars. It is compatible with most AI base addons (like ZBase).
