Hint: Auto aim
Instead of having to turn around manually to shoot the zombies, hold R1 and your character will automatically aim their gun at the nearest zombie/danger. Tap L1 while continuing to hold R1 to have your character re-adjust his or her aim. This is a much faster way to fight quick enemies, and saves ammunition from missed shots.
