One of the challenges that you have in Modern Warfare 4 DMZ is the Robbery challenge, which involves opening a safe. As simple as it may sound, locating the safe may not be an easy task since they do not always appear in the same place. Usually, they can be found in compounds or locked locations, and this means dealing with your enemies first before opening the safe. Here’s how to find and open a safe to complete the Robbery challenge in MW4 DMZ.
How To Open A Safe

In order to complete the Robbery challenge in Modern Warfare 4 DMZ, you will have to find a safe to open. Safes can typically be located inside compounds and closed-off areas on the map. First, launch a match in either Dynamic or Free Roam mode. Solo is recommended for completing the challenge to make sure no other player opens the safe first. In order to play solo, you will have to disable Squad Fill.
Now, in-game, you should open up the map and search for a compound with a tent icon. Then ping the nearest one and move towards it. Before searching the compound and opening the safe, you will have to kill all the enemies guarding it.

After you have cleared the compound, you need to look for the safe. Please note that safes do not always spawn in all compounds; therefore, you will need to look for them a couple of times before locating one. Once you locate a safe, just interact with it and open it to accomplish the Robbery challenge. There is also some good loot that you can obtain from the compound.
In case you have failed to locate any safes here, you should continue with your search in other compounds. Safes can spawn in various locations, and thus you will need to do some exploration. After you have found a safe, just open it to obtain some loot and complete the Robbery challenge. You only need to open one safe, so there’s no need to search for more after completing the objective.
