What algorithms are used to control NPCs on First Person Shooter games?

I was wondering if Reinforcement Learning has been used for this purpose in any commercial FPS games so far.

I work at a small AI startup, and our CEO worked on the AI for the NPCs in F.E.A.R. [0]. He has written about developing the goal-oriented action planning [1] approach in the game. Great to see how it was done!

Historically its been mostly hardcoded waypoints with simple state machines.
