AI stands for Artificial Intelligence and controls the behaviour of all but the simplest of NPC actions. Source's AI is not to be confused with Half-Life 2's restrained implementation of it: it is very powerful and very clever. This category will provide an overview of how to implement and manage AI in your Source game or map. As an alternative to AI, NPC actions can also be controlled by Choreographed Scenes.
