How to get the Koschei Complex Weapon Case in Warzone 2's DMZ

Koschei Complex in Call of Duty: Warzone 2's DMZ has several intriguing items. One of the primary objectives therein is to acquire the Weapon Case. However, the road to this case will be filled with hurdles one must overcome to get their hands on the Weapon Case successfully. Players will not only have to fight through hordes of AI soldiers but also engage in boss battles, solve complex puzzles, and more.

Koschei Complex was added to Warzone 2's DMZ as part of Season 3 Reloaded content. Unlike Building 21, Koschei Complex is not an Exclusion Zone on its own. This area is accessible only through the four hidden entrances within Al Mazrah. They can be found underneath the parking lot in Al Mazrah City, under the bridge that connects Taraq Village and Al Mazrah City, Access Tunnels of Rohan Oil, and finally, in the hidden passages of Oasis.

Each such entrance will present players with unique challenges to get inside the primary area of Koschei Complex, the Chemical Plant, where they will be fighting bosses and acquiring the unique rewards this grim complex holds.

How to find the Koschei Complex Weapon Case in Warzone 2's DMZ

As previously mentioned, before getting started with actually acquiring Warzone 2 DMZ's Koschei Complex Weapon Case, you must enter the initial area of the complex through one of the abovementioned pathways. Next, you must clear it off enemies and proceed to complete the puzzles to enter the main Chemical Plant.

However, it is worth noting here that these puzzles will vary depending on the entrance you chose. For instance, the Rohan Oil puzzle will require players a set of jumper cables and a car battery to access the Chemical Plant.

Before making your way to the Chemical Plant, ensure you have a pair of Night Vision Goggles, as this area is completely devoid of light. Also, there will be enemies (real and AI) you need to watch out for.

Once in, move to the middle of the plant, and you will find a hut with little light coming out of it. In the vicinity, you will find small passages. Search this area for the Factory Admin Key. Once you find it, proceed to the western part of the map and look for markings of A/1 or A/2. Inside it will be another door that can only be opened via the Factory Admin Key.

Next, clear the area of enemies and move through the Factory Admin to find the Factory Wing section of the map. As you proceed through the area, you will end up in the center of the Factory Wing. This is where you will encounter the first boss Rhino. He will be heavily shielded and will require tons of bullets to take him out. To make it easier, it is advised to use KV Broadside along with a Bomb Drone.

Once defeated, a door will open up on the northern side, giving you access to the upper levels of the complex. Take the staircase and move to the upper level. This is where you will find the second boss Sniper. However, this area will be full of traps. So traverse carefully. Avoid any of the green lasers and defuse all the wire traps.

Upon defeating the Sniper, he will drop a Secure Room Key. Pick it up. This will now mark a location for you on the map. Proceed to the location and use the key to open the yellow door. In this room, you will find the Warzone 2 DMZ's Koschei Complex Weapon Case. Once collected, you will have to securely exfil from the area.
