Two deathclaws not too far from each other and only about 20 feet away from me on the road. I can quite clearly see them, yet they seem blind to me.

[censored], I'm dead, I think to myself.

Shoot first deathclaw. Second doesn't even notice. It was a MISSILE! Come on! How is that not noticed 10 feet away from the other deathclaw? In any event the one I hit starts to charge at me.

Kill first deathclaw. Second still hasn't noticed. Hello there, I killed your mate/pack mate/child or something. Finish job. Feel cheated out of a "oh [censored]" situation.

I know the AI has never been the smartest in these games, but there comes a point where it just gets silly.

My favorite is when you kill a raider with a sniper rifle and you hear other raider's go "Oh, did you hear something?"

Well when they start putting rounds down range in your direction because they can't see you and one of them has a Fatman...

Big step up from 3/NV.

This is one of my big issues for this game. The AI on all enemies is completely and utterly stupid. Sneaking around in the base, "WHAT THE **** WAS THAT?" Literally 2 seconds later, " The Jet will make you jittery hurp derp". This happens even when I'm blowing people's heads off. I mean seriously... your buddy just died, in front of you... his gray matter is on your face. Nope the jet is making me jittery... better go take another hit. Hopefully a mod or something will overhaul the AI because i highly doubt Bethesda will.

Hmmm... I'm seeing the enemies notice me well before I've even gotten a shot off in a lot of cases

I love it, it feels like a bad movie I never manage to kill Deathclaw fair and square because no matter what I do they break at some point.
