Mastering the Koschei Complex: Locating the Elusive DMZ Shopkeeper

As an avid Call of Duty player, few things excite me more than dropping into a high risk, high reward DMZ mission. The brand new Koschei Complex exclusion zone ratchets the danger factor up to 11 – but so does the loot!

Venturing deep into this labyrinth grants you exclusive access to rare weapons, epic killstreaks and the mysterious shopkeeper…if you know where to look. Luckily, I‘ve already cracked the code on navigating the perplexing chemical tunnels and secured that prized first meeting.

In this exhaustive guide, you‘ll learn insider strategies to efficiently locate the shopkeeper and unlock game-changing DMZ upgrades.

DMZ Shopping Spree – What You Can Unlock

Before we dive under, let‘s spotlight why you NEED to track down this elusive shopkeeper. Complete his requested missions, and he grants you exclusive access to the Secure Buy Station tucked away in the factory admin room.

This shopkeeper-only buy station contains devastating killstreaks and specialty weapons you won‘t find anywhere else in Warzone 2. We‘re talking chopper gunners, orbital lasers, RPK LMGs and .50 GS hand cannons.

These gear unlocks persist between DMZ sessions, giving you a major leg up on enemies in future raids. With the right tools, you‘ll soon be mopping the floors of Al Mazrah with Overlord‘s goons!

Step 1 – Infiltrating the Chemical Processing Plant

Let‘s get straight to it! Here are the steps for locating the shopkeeper deep inside the Koschei Complex mechanical maze:

The first step is entering the facility‘s main chemical room. Look for giant yellow caution signs warning of corrosive danger to find the right area.

Once inside, stay sharp! This processing plant is filled with automated laser turrets and prowling armored commanders, ready to gun you down.

Clearing the Chemical Tunnels

Your goal here is locating one of the small tunnels branching off the main room. These contain the golden ticket – our factory admin keycard.

I suggest systematically checking each side tunnel while hugging cover to avoid alerting nearby foes. Don‘t forget to check bodies and loot chests – keys can spawn on enemies too!

Secure the Factory Admin Keycard

Once secured, this keycard grants access through locked bunker doors deeper inside the complex. Our next stop is the factory admin control room tucked away in the northern section.

Here‘s my optimal route from the chemical room, avoiding patrolling enemies:

Step 2 – Shopkeeper Showdown

Okay, keycard equipped and inside the factory admin room. Be ready for automated turret fire when you first enter! Pop an Armor Plate bundle and quickly dispatch the sentry gun to proceed.

Through the next secure door awaits your main objective – the shopkeeper! Look for a "Shop" sign to finally rendezvous with this mysterious figure.

Supplying the Shopkeeper‘s Requests

Congrats, you‘ve unearthed the Koschei Complex‘s best kept secret! But the real work is just beginning. The shopkeeper won‘t unlock those exclusive upgrades for nothing.

You‘ll need to provide him with some very specific supplies from your next few DMZ raids. And dying means losing whatever rare items he requested!

Completing Shopkeeper Missions

Here are a few of the hyper-specific requests I‘ve received so far:

  • 3x AQ Dossiers: Classified documents hidden around zones like Oasis. Details enemy movements and plans.
  • Chemical Formula Sheet: Looted from Sawmill area. Exact ingredients needed for chemical weapons development.
  • Weapon Case Receipts: Found on Armored Commanders. Tracks arms trafficking between groups.

As soon as you return and provide the requested loot, he‘ll unlock new killstreaks and guns for your future DMZ sessions!


Locating the Koschei Complex shopkeeper takes grit and dedication. But the rewards completely overhaul your DMZ capabilities for the better. With the right tools and strategy, Operators can transform from vulnerable looting scavs into extermination machines even Overlord grows to fear.

Good luck securing those highly coveted unlocks. See you inside the exclusion zone!
