Right now, noises are played relative to the character instead of to what the screen is showing. So if, say, there's a zombie to the LEFT of my character but I pan the screen so that the zombie is CENTERED, I will still hear the zombie's sounds to the LEFT.
Or, when checking if the coast is clear, I may pan the screen PAST a zombie that is to the character's LEFT, so that it now shows to the RIGHT of the screen. In this case, I will still hear the zombie on the LEFT side even when it's to the RIGHT of the screen.
This is confusing, and even dangerous when fighting in a zombie-heavy area, since it is not an audible representation of what you are actually seeing.
