Black Ops Cold War Poison Cabinet Code: How to find and unlock

If you want to experience everything Call of Duty: Black Ops Cold War's campaign has to offer, then you will need to find some codes along the way. We've already shown you how to unlock the CIA safe house door, and now it is time for the pesky Black Ops Cold War Poison Cabinet code solution. Here's how you can unlock the Poison Cabinet during the Desperate Measures mission.

Consider this a spoiler warning as we continue into the next section.

Black Ops Cold War Poison Cabinet Code

During the campaign's Desperate Measures mission, Black Ops Cold War players will come across a locked cabinet in the corner of Kravchenko’s Office.

You will need a code to open the Poison Cabinet and claim the deadly substance. For those who don't want to find it themselves, the Black Ops Cold War Poison Cabinet code is 167560.

If you want to know how we found it, the solution is quite simple but does require a bit of legwork.

First up, you need to take a look at Kravchenko's PC and read the journal entry called Nova 6 Entry 2. 

There are three chemicals listed, namely:

• S: Sulfur
• Re: Rhenium
• Nd: Neodymium

Then, head on over to the wall with the periodic table. The numbers corresponding to the three chemicals listed in the journal are:

• Sulfur: 16
• Rhenium: 75
• Neodynium: 60

With the Black Ops Cold War Poison Cabinet code now in hand, you can unlock it using the code you've found.

So what does the poison actually do? Well, you can use it to poison Charkov to get the Bunker Key which is required to complete the Desperate Measures mission.

However, this is only one of several ways to get the key out of the NPC, so you don't need to use it on him if you don't want to.
