[GameSpot] - CoD: Warzone 2 DMZ - How To Access New Koschei Complex Exclusion Zone

[343iBot]

Season 3 Reloaded is live in Call of Duty: Warzone 2, bringing a brand-new exclusion zone to DMZ mode. Instead of being a completely separate map to choose like Ashika Island or Building 21, Koschei Complex is only accessible by locating entrances around Al Mazrah. Here are all the different ways you can enter this secret location.

How to locate Koschei Complex access points

There are four entrances for the Koschei Complex map. Three are labeled as a question mark icon on the Tac-Map for Al Mazrah, and a fourth is an unmarked location. These bunker entrances will teleport you to the new map, but regardless of the path, there will be a unique puzzle to complete for each entrance.

One question mark is at Rohan Oil, and you'll be able to reach this entrance by heading down into Rohan's access tunnels. There are doors open on both sides of the underground area, but you're looking for the garage door that's only partially raised to crouch under.

Another question mark icon labels a bridge between Al Mazrah City and Taraq, and you'll find a broken wall and passage in the wall underneath it.

In the parking deck under Al Mazrah City, go down into the parking deck, where opening doors will lead you to a stairwell with a broken wall. Head through the broken wall.

The hidden location is found in the desert at the northwestmost part of the map called Oasis. This is a cluster of desert ruins, where you can find the fourth entrance to Koschei Complex.

Everyone in your team must be in the airlock room with the bunker door in order to transfer to Koschei Complex. Anyone outside will get left behind.

How to solve bunker access puzzles

External Ops bunker entrance

Here are the puzzles you need to complete based on the route you take:

Rohan Oil: This takes you to the External Ops section of Koschei Complex, and here you'll need to find jumper cables and a car battery to power up the bunker door to proceed further into the map. These will be easily found amongst the loot in the surrounding rooms.

Al Mazrah City and Taraq: Entering through the bridge will put you into a flooded area with a swimming puzzle. Swim through the rooms, following the red arrows marked on the wall. There are two sections: The first is fairly safe, but the second section will have enemies and traps to avoid. Just keep following the red arrows to the bunker door.

Al Mazrah City: This takes you to the Information Extraction section of the map, and you'll need to find jumper cables and a car battery to power up the bunker door to proceed further into the map.

Oasis: This spawns you in the Defense Research Division, and the price of picking the unmarked and somewhat stealthier entrance, comes at the cost of a three-layer puzzle.

The starting area is labeled with a three, and this will have AI enemies and bunkers filled with gas. On the control panel to your right should be a button to close the doors and stop the gas leak.

Progress to the next section labeled as two, and you'll repeat the process here. Press the button to stop the gas leak. There is one door still leaking gas, and you'll need to manually turn a valve to close it before your path will open up.

Room one will have a similar setup, but there will be a sentry gun and more AI enemies. Clear the area, press the button, and close any manual valves to stop the gas. This lets you enter a new bunker airlock and proceed further into Koschei Complex.

What's inside the Koschei Complex Exclusion Zone?

These are all the access points for Koschei Complex, so you'll want to choose whether you want the simple route at Rohan or the Al Mazrah parking deck, or go for a harder puzzle room entrance that might be less contested.

Koschei Complex works just like the other three DMZ locations, meaning you will still need to successfully exfil from the map to keep your gear and complete some specific challenges. These exfil points are marked on the map with the same blue exfil icon.

Once inside, there are plenty of areas to explore, loot to grab, and even challenges to complete. Make sure to take your best weapons and gear here.
