In campaign my gun and site is not visiable. Can anyone tell me why?
Have you activated the Blind skull?
The Blind Skull removes your HUD display, it’s the only logical reason for that to happen.
You probably accidentally turned on one of the Skulls in the game. If that’s not the case, you probably have a broken and glitched out copy of the game. It’s more likely that you unintentionally turned-on one of the Skulls, because there hasn’t been any reports of malfunctioning copies of Reach.
That fixed the problem thanks
