Counting Room Vault Key Location


In order to get the Counting Room Vault Key, players need to complete the Story Mission called “Operation Silent Ledger” in MW4 DMZ. The mission can be found in the Heavenly Luck Casino, located in the Cheongun Village, in the Counterfeit chapter. After completing the mission, the key will be unlocked automatically in the stash.
Counting Room Vault Key Use

Once you have the key, go to your Tac Map and look for the Heavenly Luck Casino right in the middle of Cheongun Village. Find the casino on your Tac Map and travel there. As soon as you arrive at the entrance to the casino, move to the right side and walk around the building till you come across the entrance to the vault.
You need to take care of yourself while moving through this part of the building, as there are some enemies here. You can shut the doors behind you so that you are able to hear any incoming enemies while looking around the room.

Inside the vault, you will find several valuable items. Look around carefully, as you may also find crafting recipes, including one for the Zip Gun. These recipes are worth collecting because they unlock useful crafting options.
There is also a back room within the vault that holds two more locked chests. Interact with each one and press the necessary button to unlock it. There is the possibility of gaining even more valuable loot from them, so make sure to check both before exiting.
Enemies can arrive when you are looting, so get ready to face several enemies at once. You can place traps if you have them to take care of the approaching enemies. One of the items that you can find here is a Gold Skull that sells for approximately 25,000.
Given the value of the loot inside, it will be worth paying a visit to the Counting Room Vault after completing your objective in the area. Collect everything you can, then head to an extraction point to secure your rewards.
