01

14th Political Prison

C3 · Northwest

High Citadel: Critical

A walled prison on a cleared plateau with a watchtower on every corner and the Y-shaped Citadel, a maze of cell blocks, in the yard.

Play
Squad up and scout the Citadel from outside before you go in, so you are not surrounded. Barracks sit on the east side.
Bosses
Lieutenant The Warden, in the mess hall. He pushes behind a riot shield: flank him or flash him so he drops it.
Materials
Nylon Cloth and Nylon Laminate in the Citadel wings; Nitro Compounds and Volatile Explosives in the Prison Yard chemical buildings.
02

Chang-san Air Base

B5 · West

Critical Bunker: Extreme

A military base cut into a granite hillside: runway, hangars, barracks and a command building over an underground bunker. Three SAM sites guard it.

Play
Your best armor, a medkit and a full squad. The bunker is a separate Extreme run; its doors are on the southern hillside, reached through the woods.
Missions
Operation Iron Citadel (Story Mission). The SAM sites work for Eye in the Sky.
Bosses
Colossus has been met in the bunker. One tracker places Lieutenant Bale in the bunker's tank depot; most guides put him in Deadtown.
Materials
Structural Alloy and Alloyed Plating (hangar, repair bay), High-Tenacity Fibers and Ballistic Fabric (armory, barracks). Detonators, Reactive Metals and Electronic Sensors are often seen here.
03

Deadtown

B7 · Southwest

Low Re-Education Center: Medium

An abandoned farming town between two toxic rivers: street fights above ground, sewers below, a clinic and gas station at each end and military storage in the raised blocks by the river.

Play
Good mid-step after the Low areas. Enemies stack up around the two central buildings of the Re-Education Center; use the sewers to move unseen.
Missions
Execute Intel (Counterfeit). The town also has a Lieutenant Hunt tower for Hunter.
Bosses
Lieutenant Bale, at the Re-Education Center. He throws smoke constantly: push through it or bring a thermal optic.
Materials
CPU and Comms Module in the hillside facade buildings; Nylon Cloth and Nylon Laminate in the underground holding area.
04

Imjin Farmland

D7 · South-west

Low Rice Mill: Medium

Rice fields, farms, narrow roads and rail lines on a floodplain, with the Rice Mill towering over the fields.

Play
Long sightlines and little cover: bring a long-range weapon and expect snipers. Approach the Rice Mill through the warehouses. Ammo and armor caches make it a good restock stop.
Materials
Stock Rod and Turned Components in the rice mill; Nitro Compounds and Volatile Explosives in the storage tents. Players also report Experimental Compounds on the ground here.
05

Cheongun Village

F4 · North

Low Heavenly Luck Casino: High

The northernmost South Korean village, split by the border crossing to Russia. The Heavenly Luck Casino is a fortified block of dark gambling halls over several floors.

Play
A quiet start outside the casino. Inside, bring night vision: the underground car park has no power.
Missions
Operation Silent Ledger (Counterfeit finale, the casino vault) and Eyes Everywhere (mark enemies in the casino with a Recon Drone).
Bosses
Lieutenant Jin-Tae, in the casino. Colossus is reported patrolling the village.
Materials
Nylon Cloth and Nylon Laminate in the casino's Mujin Nightclub; Control Unit and CPU are also seen here.
06

Mirae General Hospital

F5 · North-central

Low

A hospital beside a train station between Cheongun Village and Hajin City, with triage tents and barracks outside and wards inside.

Play
The usual first farming stop. Close-quarters fights through the wards: bring an SMG or shotgun.
Missions
Operation Critical Extraction (Human Intel finale).
Bosses
Lieutenant The Doctor, in the parking garage, in a white hazmat suit. He drops the Command Office Key for a locked room on the top floor.
Materials
The best spot for Biomaterials, Binding Catalyst and Stabilized Reagents (medical cabinets, first aid kits, medical tents).
07

Cheonwang Peak Array

F6 · Centre

Medium

The biggest telecom array in Hajin, on a flat summit in the middle of the map, with barracks, a rooftop helipad and server buildings.

Play
Hold the high ground for long views over the centre, then work through the server buildings for safes and electronics.
Bosses
Lieutenant Iskra, at the array. Lieutenant Gorani roams the forest to the south toward Mujin Pass: he throws smoke and decoys, so check your target before you fire.
Materials
CPU and Comms Module in the server rooms.
08

Haneul Nuclear Reactor

I4 · Northeast

High Radiation

The damaged nuclear plant on an island in the northeast, under a spreading radioactive cloud that gets worse inside the facility.

Play
A gas mask and radiation gear are required: fire stations hold radiation gear. Get in by water or through the Compound Delta tunnel.
Missions
Operation Fallen Ember is reported to take you inside.
Bosses
Lieutenant The Chemist, in the radiation zone with a few guards. Fog limits vision: a gas mask covers the yellow zone, a hazmat suit the red zone.
Materials
Printed Circuit Board and Power Regulator.
09

NuriGO Mall

H6 · Hajin City

Medium High

Shops, a police station, a clinic and City Hall above an unlit underground mall at the north edge of Hajin City. Guides disagree on which half is High threat, so treat both as hot.

Play
Night vision for the mall below ground. Grab crafting materials and valuables first instead of filling up on low-value loot.
Missions
Operation Shopping Hacks (Underground finale).
Bosses
Deathstalker is often seen overhead. Our mission data puts Lieutenant Jang-ui's encampment here; most boss guides fight him in The Grid.
Materials
Nitro Compounds and Volatile Explosives in the DRC lab; Rigid Synthetics in shops and duffel bags.
10

The Grid

G6 · Hajin City

Critical Netshin Tech Complex: Extreme

The walled business district at the centre of Hajin City and the toughest area on the map: DBN Headquarters, Hanex Bank, Hotel Lucera and the Netshin Tech Complex, with barricades, watchtowers and rooftop fights.

Play
Coordinated, well-geared squads only. Clear drones and turrets before you take on the bosses.
Missions
Operation Grid Assault (Story Mission). It rewards Roze's Highrise Armory key for the armory in Netshin.
Bosses
Lieutenant Roze on the DBN Headquarters rooftop (can one-shot you, so never push in a straight line) and Lieutenant Jang-ui on the 15th floor of Netshin, among exploding drones and laser turrets. Deathstalker patrols overhead.
Materials
CPU and Comms Module in the Netshin server rooms; Stock Rod and Turned Components in the construction zone.
11

Wolves Stadium

G7 · Hajin City

Medium

A ruined baseball stadium in the south of Hajin City, ringed by shops, apartments, a theatre, a police station and Compound Echo.

Handy for Orders that need a police station or a compound: Hostile Force, Robbery, No One Left.
Materials
Electronic Sensors are reported here.
12

13

Songdo Wharf

I7 · Hajin City

Low

The east side of Hajin City, from the reactor down to the river's south fork: apartments, a market, a pier, a lighthouse, Oamsik Turtle Island and working train and monorail lines.

Play
A calm loot area, but check for other squads before you climb anything exposed.
Missions
Triangulation (Underground): place a transmitter on the La Grande Vie antenna mast.
Bosses
Deathstalker often hovers over the wharf, and Colossus is reported patrolling here.
Materials
High-Tenacity Fibers and Ballistic Fabric on the La Grande Vie rooftop; Control Unit at Songdo Pier; Biomaterials and Volatile Explosives on Oamsik Turtle Island.
