DMZ Guide – What is Koschei Complex & How to get access to it

DMZ Koschei Complex

One of the most notable changes in Warzone 2 Season 3 Reloaded is the addition of the Koschei Complex to DMZ. Here’s everything you should know about it.

DMZ Guide – How to get access to Koschei Complex

The Koschei Complex can be accessed from any one of its four entrances. Out of the four locations in Al Mazrah, three have question marks on the Tac-Map, and the other is blank. These bunker exits are portals to the new map, but each one requires solving a different puzzle before you can exit.

Rohan Oil

If you go down into Rohan’s access tunnels, you can get to this entrance. There are open doors on both sides of the underground area, but the one you need to crouch under is a garage door that’s only raised halfway.

Puzzle

If you want to continue through the map, you’ll need to find some jumper cables and a car battery in the External Ops area. These can be found among the loot in the nearby rooms.

Al Mazrah City

Go down into the parking deck beneath Al Mazrah City, where opening doors lead to a stairwell with a broken wall. Pass through the shattered wall.

Puzzle

Similar to the puzzle in the Rohan Oil entrance.

Al Mazrah City and Taraq

A bridge connecting Al Mazrah City and Taraq is marked by a second question mark icon.

Puzzle

A swimming puzzle awaits you if you cross the bridge into the flooded area. Follow the red arrows marked on the walls as you swim through each room. There are two parts to this: The first section is relatively safe, but the second will contain enemies and traps to avoid. Continue to follow the red arrows until you reach the bunker door.

Oasis

The hidden location is called Oasis and is located in the desert in the northwest corner of the map.

Puzzle

This places you in the Defense Research Division, and the cost of choosing the unmarked and somewhat more stealthy entrance is a three-layer puzzle.

The starting area is denoted by a three, and it contains AI enemies and gas-filled bunkers. On the control panel to your right, there should be a button to close the doors and stop the gas leak.

Continue on to Part 2 where you will do it all over again. To turn off the gas, press the button. One of the doors is still letting gas out, and you’ll have to turn a valve by hand to seal it before you can proceed.

Room one will be similar, but it will include a sentry gun and more AI enemies. To stop the gas, clear the area, press the button, and close any manual valves.

DMZ Guide – What is Koschei Complex?

The Koschei Complex is a mysterious subterranean compound hidden in an undisclosed location in Al Mazrah. Because this area will be poorly lit, it is recommended that you attach flashlights to your weapons, but you will also be able to find NVGs in the Koschei Complex. It also has “some of the toughest [[REDACTED]] outside of Building 21.”

Once inside, there’s a ton of stuff to do, from exploring to looting to completing challenges. Bring your finest armor and weapons.

You’ll still need to successfully exfil from the map to keep your gear and complete some specific challenges in Koschei Complex, just like you would in any of the other three DMZ locations. The same blue exfil icon is used to mark these exfil points on the map.

That concludes the information we currently have regarding the Koschei Complex in Call of Duty DMZ.
