Audio problem: The zombie chasing the man gets tangled on a wire fence and gets shot in the head. When the bullet impacts his skull he makes a grunting pain noise just like everybody else who gets shots in movies makes the same grunt. First of all zombies don't feel, so how can he express pain, and secondly when people get shot and die they don't grunt, they drop dead. (00:09:30 - 00:10:00)
