I hope that the AI is better in F.E.A.R 3. Actually, I hope that the enemies in number three are more fearsome, in general.
I ended up feeling sorry for the lackluster foes in F.E.A.R 2, in particular those unfortunate Armacham soldiers. They spend the entire game getting horribly massacred by you, your squad, Alma, the Replicas, the abominations, remnants, phantoms, and nature itself. Those guys need to unionize.
