Weak point

The head. Some carry knives.

Tactic

Standard zombie: a head or leg shot staggers it, then a shove with A (Grace) or a kick (Leon) and the finish. Destroy the head or inject it, or it comes back as a Blister Head.

Collection & Testing (chapter 6): use the wall-mounted Disposal Tanks: they spray hemolytic gas and an infected bursts after 3-5 seconds. Tanks run dry: move on to the next one. Without the gas, they mutate into Blister Heads.
Cemetery escort (chapter 7): Leon picks them off with the Classic 70 from the windows; reload only when nobody is near Grace.
If a zombie grabs Grace, she uses up the knife to break free (it stays stuck in the zombie; you get it back if it dies) or takes a bite.

Drops

Blood for Grace's Blood Collector; Transfusion Bags in some rooms.

Insanity: 3 in the Pantry (they rise as you enter), 1 in the Blood Reports Room and 5 on arrival at the Cemetery (3 on Standard). On Insanity a grab can kill Grace even at full health (Game8).
