The final Tier 5 Black Mous faction mission is one of the most time-consuming and complex missions in Call of Duty: Warzone DMZ. Crack The Code tasks you to acquire the special diamond-tipped drill and use it to open the Factory Safe. In this guide, I’ve shown in detail how you may complete this mission fast and with ease.
Below are all the objectives for Crack The Code:
Items required for this mission
Before we begin, I want to brief you on some items I recommend you take with you to Crack The Code:
Now, deploy into Al Mazrah and then travel to Koschei Complex via theentranceof your choice. Make your way to the Chemical Plant section and equip yourNight Vision Gogglesfor clear vision.
Where to find the R4D Detector and Factory Admin Key
To solve the puzzle of the keypad-locked room inside Alpha Cluster, you’ll need the R4D Detector tactical equipment. This gadget can be found inside thetwo small office roomsin theChemical Plantsection. Also, get your hands on the Factory Admin Key that should be sitting somewhere in the nearbyvents.

Where to find the Alpha Cluster and how to unlock it
Once you have the required items, head in thesouth directionuntil you come up onBunker Door C/1 or C/2. Between these doors, you’ll find a breaker panel where you need toplace the Car Battery and Jumper Cablesyou brought with you. This will power up the bunker doors, which you can then unlock to access the Alpha Cluster.
Make your way inside the Alpha Cluster, and at thewest endof the sector, you’ll find two sentry turrets guarding an area. Take out the guards and the turrets and approach thekeypad-locked room, as shown in the first image. Scan the keypad next to the door with your R4D Detector, and you’ll seethree symbols. Todecipher these symbols, look forchalkboardsaround the Alpha Cluster and scan them using the R4D Detector.
Each chalkboard has a symbol, and it may or may not be the one you need to decipher. If you find a chalkboard with one of the symbols you need to decode, note the number associated with it. In my case, the digit for the first symbol B was 5 as you may see in the last picture. Also, beware of the laser traps and guards while exploring the area.
Once you have decoded at least two of the symbols, go back to the keypad-locked room and try to unlock the door by guessing the third digit that you don’t know. For instance, I knew the first two digits were 5 and 7, so I started using numbers from 0 to 9 for the third code until I finally unlocked the door. Now, pick up theDiamond Bit Drillfrom the table and head back out of the Alpha Cluster. You can also take theHeated Madness blueprintpart from the room.

Where to find the safe in the Factory Wing
In thenorth end of the Chemical Plant, you’ll findBunker Doors A/1 and A/2. Enter either one of these airlocks and use the Factory Admin Key to unlock the yellow door. This will lead you to the Factory Admin section, where you can access the Shopkeeper buy stations. I highly suggest you fill up your backpack with munition boxes and armor plates, as you’ll need them soon.
Proceed further inside the area while fighting off bots, and you’ll eventually reach theFactory Wing. This is the section wherethe Rhinoceros and the Sniperare held up. While the Rhino will be on the same level as you, the Sniper resides one floor above that you may access only via the door you can see in the image above.
Now, you can take out the Rhino in one magazine of theKV Broadside Shotgunif you have the 25 Round Drum mag and Dragon’s Breath attachments on it. Make sure to shoot him up close and be prepared to take some damage.
Alternatively, the easiest way to take the boss out is by using theBomb Dronekillstreak. Sit in a safe spot away from the bots and fly the Bomb Drone close to the Rhino before detonating it. Similarly, use the second Bomb Drone, if you have it, to kill the Sniper hiding on the top floor.
Once the Rhino is down, take the stairs up and carefully dodge and disable thelaser traps. Now, kill the Sniper if you don’t have the second Bomb Drone. Once the Sniper is down, he’ll drop aSecure Room Key. Grab this key, and the Secure Room will be marked for you. But for this mission, you don’t even have to unlock that door as thefactory safesits in the corner outside the room (see image).
How to drill the safe in the Factory Wing
The next part is simple, just approach the safe and press the interact button tostart drilling. Remember, this is only possible while you’re carrying the diamond-tipped drill from the Alpha Cluster. Wait until the drilling process is over for the safe to open. Inside the safe, you’ll find three types of vests,Dr. M’s Lab NotebookandBunker Safe Note.
I stowed both the notebook and safe note into my backpack just in case. Once you’ve picked up the two items, all you have to do is exfil from Koschei Complex to complete the Crack The Code mission. I suggest using theL2 Restricted Zoneinside Factory Wing to extract as it’ll be safer than the Chemical Plant exfil elevator.
