This Call of Duty: Warzone 2.0 guide explains how to enter the Chemical Plant in the DMZ Koschei Complex map.

DMZ has received one of its most significant additions in Season 3 Reloaded. It’s a new exclusion zone called the Koschei Complex.

But it works differently to DMZ’s other maps. The Koschei Complex can only accessed via specific hidden entrances in Al Mazrah. Once you’re inside the complex, there is no tac-map available to help. This makes navigating the facility challenging, particularly because it’s full of locked doors.

At the heart of the Koschei Complex is the Chemical Plant. This area connects the facility with all of its other areas and acts as a central hub of sorts. It is also the only area of the Koschei Complex that players can exfiltrate from.

But getting inside the Chemical Plant isn’t straightforward and there are some specific steps you must take first. Check out the guide below detailing how to enter the Chemical Plant in the DMZ Koschei Complex.

How to enter Chemical Plant in Koschei Complex (DMZ)

This is how to enter the Chemical Plant in the Koschei Complex:

To find the entrance(s) to the Chemical Plant, follow the large red arrows painted on the walls of the Koschei Complex. These arrows will lead you to an airlock door. The Chemical Plant is through the door, however there is no power and the door cannot be opened.

Follow the red arrows.

Collect the “Power Supply” note on the wooden crate near the door. This provides instructions explaining how to restore power. You need to find a car battery and jumper cables. These items are random but fairly common, so search nearby rooms and they should turn up relatively quickly.

Follow these instructions to power the door.

Once you have a car battery and jumper cables, go to the open breaker panel next to the airlock door. Insert the items and power will be restored. Next, press the large red button on the wall to the right of the door. It will open, allowing you to enter the Chemical Plant.

The Chemical Plant is a challenging area. It is almost pitch black and full of enemy soldiers and other operators. So, ensure you enter equipped with flashlights on your weapons and night vision goggles.
