Your controller is going to eat it's batteries if you're far away enough from the receiver. Enough trips to the kitchen from my room while talking to my friends over party chat seems to drain them faster than just leaving the controller behind.
I had my gun drawn on the main surgeon and went up to his face with it. I then tried to melee him to try and knock him out or something and Joel ending up slicing the dude's jugular with his own scalpel. It was disappointing because it's not like you can find surgeons popping up everywhere in this post-pandemic world and Joel just fucking wastes him.
