Concentrated Fire

Concentrated fire is an exclusive ability for humans in Zombie 4: Darkness

Overview
The user is able to perform this ability once the Gauge meter has reached at least 30%, once activated all shots will be counted as a headshot. The more percentage you have, the more it will last.

This is essential when is about killing zombies as any zombie killed while it's activated won't be able to respawn except if at midnight, they will only get stunned or killed temporally.
