Zombie Army 4 Dead War: How to open safes - Ultimate Guide

The indication that a safe is closed is the red light it emits, but just because it is closed doesn't mean that it can't be opened, but you will have to do something first.

After the first mission in the game you will find a safe in a shed near a bridge that crosses the train tracks and when you approach the shed you will hear a cry for help. You will have to save at least one person so that the safe remains open and you can loot it, but if you don't save anyone and you die the safe will close and you will have to try again.

Just like this, every safe requires you to do something before you can access it, all require something different and offer a unique reward when you open them, although not everything you find is impressive, many things are worth it, so it's good to know how to open them and to unlock them when the opportunity arises.
