John grit his teeth. Between him and the only exit out of the ally was three zombies. Ordinarily it wouldn't be a problem, but he'd recently fired off the last of his ammo and had no knives on him. He steeled himself to overpower them, though it was unlikely he'd get all three. He was even more surprised when an arrow went through the head of one. His ears picked up a sharp whistle that caught the zombies' attention before the left most one was behead by a... wolf and the right another arrow.
