HL1 has still better AI *shrugs* I think the situations where the AI is using cover in F3 is rather coinsidence than realy the AI working. Hell, not even in Skyrim is the AI really taking cover - archers for example tend just to move a little bit from side to side to avoid your arrows. You can see this by the fact that the objects in the F3 game world are very poorly designed for cover-gameplay as it is pretty normal that the textures don't match with the obstacles. You will constantly see your bullets geting eaten by invisible edges where the model sticks out of the texture. Likea around corners, rocks, the gabs between a fence etc. I know games that fixed that stuff as well 15 years ago.
