F.E.A.R. was the first video game to use Goal-Oriented Action Planning (GOAP) for its AI.

The 2005 game F.E.A.R. pioneered the use of GOAP, a planning system derived from academic AI called STRIPS. Unlike traditional game AI that relies on fixed scripts or finite state machines, GOAP allows NPCs to select goals dynamically and plan sequences of actions to achieve them. This creates more flexible and believable enemy behavior that adapts to player actions in real time.
