It's a game mechanic that dramatically slows down time and gives you a unique HUD for targeting, placing your shots, and assploding the F out of someone or something's head in a giggly spray of blood and gore. Vault-Tec Assisted Targeting System - is one of those things that Fallout diehards love to argue about. I hear someone somewhere scoffing at the idea as they look for their New Vegas CD and I don't even care. can make you a total badass if you do it right. One thing at least hasn't changed at all. I guess that was the whole idea and it turns out that playing FO4VR puts your head on a swivel and makes a fun game even more fun. When you're meandering through the wastes on your way to help that damn settlement for Preston and you hear Dogmeat barking or Piper screaming behind you, it almost feels like something is really behind you. I don't wanna be that guy and say it feels more immersive but holy crap does it ever feel more immersive.
