I learned there is a cover mechanic. Peek around corners at your enemies. Spy on your loved ones. Play peekaboo with Strong and Dogmeat

Also, no real glitches here. A minor hiccup once in a while that won't let me look at my pipboy. Just have to change views to fix it real quick. But one thing that does seem to happen on occasion is Dogmeat will randomly disappear. And then yelp. And be hobbling when I find him. I caught him once. Learning to fly. He just randomly takes off into the air. So high that he basically dies on impact. Except he can't die. And he makes a horrible Superman. His breath stinks
