DMZ Sniper Guide: Koschei Complex Access, How to Defeat, and LA-B 330 Blueprint Unlock

DMZ Sniper Guide: Koschei Complex Access, How to Defeat, and LA-B 330 Blueprint Unlock

Deep beneath Al Mazrah lies the Koschei Complex a sprawling underground bunker filled with secrets, high-tier loot, and two of DMZ's most dangerous bosses . The Sniper, also referred to in-game as "Overwatch," is the final guardian of this labyrinth . Unlike the close-quarters brutality of the Rhino on the ground floor, the Sniper is a precision threat who can eliminate operators from across the Factory Wing with a single shot from his Victus XMR .

This guide covers everything you need to know: how to access the Factory Wing, why you must defeat the Rhino first, how to navigate the trap-filled upper level, the best combat strategies, the exclusive LA-B 330 blueprint reward, and mission requirements like Brothers in Arms and Hunting Party.

Who Is the Sniper?

The Sniper is a boss commander in the Koschei Complex, introduced in Season 3 of Warzone 2.0's DMZ mode . According to his in-game biography, he was sent with the Rhinoceros as reinforcements by Al-Qatala to defend the Factory Admin sector from intruders .

Key Characteristics:

  • Alternate Name: In-game subtitles refer to him as "Overwatch" 

  • Location: Upper level of the Factory Wing section, Koschei Complex 

  • Access Requirement: Only reachable after defeating the Rhinoceros boss on the ground floor 

  • Primary Weapon: Victus XMR sniper rifle one-shot potential 

  • Secondary Weapon: Lachmann Sub SMG for close encounters 

  • Guards: Multiple Al-Qatala soldiers on the upper level 

  • Defenses: Laser traps and trip mines throughout the approach 

Critical Note: The Sniper will fire at players in his line of sight, whether they're on the lower or upper level. This means during the Rhino fight, you're also under sniper threat .

Getting to Koschei Complex

Before you can fight the Sniper, you need to reach the Koschei Complex itself.

Koschei Complex Entrances

There are four entrances to the Koschei Complex located across Al Mazrah :

Entrance LocationRegionDescription
Rohan OilNorth Al MazrahParking lot area, follow train tracks, look for crack in wall 
Taraq VillageEastern Al MazrahCrack in wall beneath bridge northeast of village 
Al Mazrah CityCentral cityOne of four possible entry points 
OasisSouthern desertOne of four possible entry points 

Initial Navigation

  1. Enter through any entrance and follow the path to the Chemical Plant

  2. This area is dark you'll need Night Vision Goggles (found in nearby lockers or brought with you) 

  3. Navigate to the center of the Chemical Plant

  4. Look for a hut with small passages nearby this is where Factory Admin Keys spawn 

Accessing the Factory Wing

The Factory Wing is where both the Rhino and Sniper are located. You cannot reach the Sniper without first entering this area and defeating the Rhino .

Factory Admin Key Requirement

ItemLocationNotes
Factory Admin KeyChemical Plant vents and small rooms near central hut Only 2 spawn per lobby, be quick

Finding the Key:

  • Check the small rooms and vents surrounding the central hut in the Chemical Plant 

  • Only two keys spawn per match, so competition is fierce 

  • Once obtained, look for bunker doors marked A/1 or A/2 

Alternative Entry: Emergency Door

There's a second way to reach the Factory Wing through the Defense Research Division:

  1. Enter Koschei Complex through the Oasis entrance (north of Rohan Oil) 

  2. Navigate to the alternate exit door

  3. This puts you behind the Rhino's position, potentially offering a tactical advantage 

Pro Tip: If using the emergency door method, you can reach the Rhino before alerting Level 3 AI soldiers, giving you a brief window of surprise .

The Rhino Fight: Prerequisite to the Sniper

You cannot reach the Sniper without first defeating the Rhino. When you enter the Factory Wing's large central room, both bosses are present simultaneously .

What to Expect

ElementDescription
Rhino LocationGround floor, center of large room

Rhino Combat Tips

  • Rush him down with close-range weapons shotguns excel here 

  • KV Broadside with Dragon's Breath is highly effective 

  • He charges with melee keep distance while shooting 

  • Clear additional soldiers that spawn during the fight 

  • Cluster mines and anti-armor rounds help significantly 

  • Munitions boxes essential he requires hundreds of bullets 

Once the Rhino is defeated, a door opens automatically in the northwest or northern section of the Factory Wing, granting access to the upper levels .

Navigating to the Sniper

The path to the Sniper is deliberately treacherous.

Traps and Defenses

Combat Strategies: How to Defeat the Sniper

The Sniper fight requires a different approach than the Rhino. He can kill you in one shot if you peek carelessly .

Strategy #1: Bomb Drone (Safest)

This is the most effective strategy, especially for solo players or the Hunting Party mission .

How to Execute:

  1. Purchase Bomb Drones at Buy Stations in Al Mazrah for $9,000 each before entering 

  2. Stop before reaching the Sniper's position don't alert him yet

  3. Use one Bomb Drone to target the Sniper directly

  4. Watch for his rifle he may shoot your drone if he spots it 

  5. Take him out with one hit Bomb Drones are lethal to bosses

Why This Works: You eliminate him from complete safety, never exposing yourself to his one-shot rifle.

Strategy #2: Close-Range Rush (Traditional)

If you prefer direct engagement:

How to Execute:

  1. Use smoke grenades to reduce visibility while moving through traps 

  2. Once past traps, rush his position he's less effective at close range

  3. Use KV Broadside or other high-DPS close-range weapons 

  4. Quick-peek corners to avoid giving him a clean shot 

  5. Use grenades to soften him before engaging 

Strategy #3: Squad Coordination

How to Execute:

  1. One player draws aggro (risky requires good cover)

  2. Others flank while he's focused

  3. Focus fire once in position

  4. Clear AI soldiers first to avoid being overwhelmed 

General Combat Tips

  • He can one-shot you never stay exposed 

  • Use smoke to obscure his vision while moving 

  • Bomb Drones work on both bosses one each 

  • Once he's dead, loot quickly the area will attract attention
