You smash the bottle into the closest one's face

From Create Your Own Story

You swing the bottle hard. It shatters on the zombie's cheekbone, crushing the bone in and pulping the brain inside it. The body falls to the ground as you stare in shock. Your hand is cut and bleeding from the broken bottle and the others are still coming at you without any reaction to the apparent death of the fallen one.
