and found myself thinking the exact same thing when I see enemy npcs they seem to be way more 'alert' in the way they move and this mod highlights that problem and solves it, It would be nice to see a small animation overhaul or switch out so that the player character doesn't look like it's oblivious when combat starts, perhaps maybe make it so that the sole survivor has different animations for being in combat and out of combat? Bethesda pulled it off with the Assaultron helmet. >_>
