Descending into the shadowy depths of the Koschei Complex in Call of Duty: Warzone 2‘s DMZ mode offers immense rewards. But many operators have met their demise in the pitch-black corridors before uncovering the valuable loot hidden within. This comprehensive 2200+ word guide provides everything you need to safely navigate the complex and take home high-tier weapons, rare intel, and other prizes.
History and Background of the Koschei Complex
The sprawling subterranean Koschei Complex located beneath Al Mazrah was originally constructed in the 1960s as a secret biological weapons research facility under Soviet control. Named after the immortal villain of Russian folklore, Koschei the Deathless, the classified complex focused on chemical and viral warfare projects before being abandoned decades later.
With the fall of the Soviet regime in the 1990s, the Koschei Complex was left to decay deep under the city streets of Al Mazrah. However, rumors of valuable technology and relics hidden in its depths have drawn modern operators to explore the treacherous, labyrinthine halls. Entering the complex is extremely risky, but those who survive can uncover relics of the Cold War era and cutting-edge modern weapons and tech.
Overview of the Koschei Complex Layout
The Koschei Complex is absolutely massive, with a footprint of over 250,000 square feet according to declassified records. It was designed to be entirely self-sufficient, with living quarters, storage depots, research labs, and a subterranean power plant located deep below the main complex.
Based on intel gathered by previous infiltration teams, we know the multi-level Koschei Complex contains the following areas:
-
Research laboratories and testing facilities
-
Barracks and living quarters for up to 500 personnel
-
Storage rooms and vaults
-
A records archive with documents and data
-
Decontamination chambers
-
A subterranean hydroelectric power plant
-
Maintenance corridors and utility tunnels
-
A mainframe supercomputer command center
Many sections have collapsed, flooded, or become otherwise inaccessible over the decades of abandonment. But for those willing to brave the hazards, the secrets of the Koschei Complex are ripe for the taking.
Locating the Entrances to the Koschei Complex
Venturing into this Soviet-era relic will require accessing one of several possible entry points. These hidden entrances are located across Al Mazrah:
Northern Entrance
This entrance is discreetly located underneath a bridge on the north side of Taraq Village, following the riverbank west just past the dam. It leads directly into the basementLevels Konuko of the complex through a drainage grate.

Parking Garage Entry
A barricaded door inside the parking garage in downtown Al Mazrah City opens into the south wing of the Koschei Complex. Look for the door in the southwest corner of the garage.
Rohan Oil Tunnels
An isolated hatch tucked away deep in the Rohan Oil pipelines provides another path into the complex. Following the pipes southwest of the Rohan Oil factory leads to maintenance tunnels and access shafts.
Sewer Drain Access
Finally, a drain grate connected to the sewer system under central Al Mazrah also allows covert access to the Koschei Complex. This dark, damp route keeps you hidden.
I‘d recommend the parking garage or northern entrances for first-timers. The Rohan tunnels and sewers can be extremely challenging to navigate for operators unfamiliar with the layout.
Approaching and Infiltrating the Koschei Complex
Once you‘ve marked your infiltration point, here are some key tips to get inside safely:
Gear Up Accordingly
Make sure your loadout is tailored to the close-quarters combat of the complex:
-
An SMG or shotgun primary is ideal for tight spaces
-
Throwables like flash or stun grenades help clear rooms
-
Pack a pistol with a laser sight for quickly addressing close threats
-
Bring multiple armor plates – you‘ll likely take damage clearing sections
-
NVGs or a tactical flashlight are a must for the pitch black halls!
Move Slow and Steady
The claustrophobic corridors provide endless spots for an ambush. Take it slowly:
-
Pie each doorway, using corners or objects as cover
-
Check your minimap constantly for enemy signatures
-
Stop and listen periodically for footsteps or movement
-
Don‘t rush – methodical movement will keep you alive
Travel in Numbers
Having teammates watching your back is extremely beneficial. When in a squad:
-
Space properly to avoid grenades wiping you all out
-
Assign roles like pointman or rear guard to keep things organized
-
Flank and collapse on enemies together to overwhelm resistance
-
Have a designated navigator to reduce getting lost in the maze
Avoid Hazards
Keep an eye out for environmental hazards:
-
Collapsed sections blocking paths
-
Flooded areas hiding underwater mines
-
Exposed electric wires and cables
-
Unstable structures that could collapse
-
Lingering chemical contaminants
What to Expect Inside the Complex
Once you manage to pass through those imposing blast doors, you‘ll need to navigate winding corridors, avoid hazards, and be prepared to fight to uncover the most valuable loot. Here‘s what you might encounter within:
AI Combatants
Multiple areas are guarded by AI enemies like armored heavy gunners. Using cover and coordinated squad attacks are key to breaking through these strongholds. The Armored Commander in particular has a 20% chance of dropping a rare weapon case.
Dead Ends and Obstructions
Parts of the complex have collapsed or flooded over time. Expect to find blocked paths that will force you to backtrack and find alternate routes. Refer to your map frequently to avoid getting turned around.
Loot Cache Rooms
Keep an eye out for locked rooms marked "Oruzhiye" (Russian for "weapons") or "Oborudovaniye" ("equipment"). Breaching these rooms often reveals weapon lockers, supply caches, and rare item spawns.
Research Labs
The research labs contain filing cabinets with keys, research documents with hidden codes, and computers with access codes that unlock deeper areas.
The Vault
According to surveillance footage, an armored vault door in the basement lab Level X conceals chemical caches and prototype weapons. Finding the vault key hidden somewhere in the complex is a top priority.
Hazmat Zombies
Some areas still show traces of chemical contaminants. Expect to encounter undead hazmat suited creatures that move slowly but dish toxic damage. Aim for headshots and keep your distance.
Enemy Operators
Of course, other infiltrating Operators may be lurking in the shadows. Remain alert and be ready for close-quarters firefights in the halls. Use suppressors to avoid drawing unnecessary attention.
The Collapse
Note that the collapse circle still closes in while underground! Don‘t lose track of time while looting or you might find yourself trapped. Plan an exfil route in advance.
Recommended Loadouts for the Koschei Complex
Entering the Koschei Complex prepared with the right loadout tailored to its challenges will give you a major advantage. Here are two top loadout recommendations:
CQB Raider Loadout
Perfect for quickly clearing rooms and securing loot.
Primary: Fennec 45 SMG – Agile and hard hitting for close engagements
Secondary: P890 pistol – High handling and mobility
Tactical: Flash grenade – Clear rooms before entering
Lethal: Drill charge – Breach locked doors
Perks: Double Time, Tracker, Spotter, Fast Hands
Infiltrator Loadout
Ideal for stealthily infiltrating deeper into the complex.
Primary: Honey Badger Assault Rifle – Integrated suppressor to stay quiet
Secondary: X13 Auto pistol – Quick follow-up shots
Tactical: Stim – Revive yourself if compromised
Lethal: C4 – Set traps or destroy obstacles
Perks: Cold Blooded, Tracker, Spotter, Ghost
Additional Tips for Dominating the Koschei Complex
Here are some final advanced tips and strategies to give you the best chance of extracting with rare loot from the Koschei Complex:
-
Use suppressed weapons to avoid drawing unnecessary attention.
-
Study your Tac Map to identify possible extraction points before heading underground.
-
Note key landmarks and room names to help navigate the maze.
-
Collect keys, codes, and access cards as you go to unlock new areas.
-
Leave some loot behind initially if you‘re encumbered – you can return for it.
-
Exfil from a different entrance than your insertion point to evade pursuers.
-
Achieving the Subterranean badge (extract 3 items from below Al Mazrah in one match) grants a unique calling card.
In Conclusion
Raiding the infamous Koschei Complex is certain to test the combat skills and nerves of any operator brave enough to try it. But coming prepared and moving carefully through the eerie, darkened corridors can lead to high-value rewards. This guide covers everything you need to know to discover the complex‘s hidden treasures. Stay frosty down there!
