Hajin is the launch DMZ map in Modern Warfare 4. Use the live Tac-Map to check your deployment's objectives, radiation, exfils and nearby threats. This static reference helps you recognize the major locations and useful buildings; it does not show live loot, enemy positions or an extraction point guaranteed for every run.
Start with the place named by your objective, then check its smaller landmark and current threat. The danger shown for AI does not include rival human Operators.
Read the Tac-Map before choosing a route
Open the Tac-Map to zoom, inspect icons and place a squad ping. Grid letters run west to east and numbers north to south. The official Hajin guide uses D7 for Imjin Farmland as an example; keys also include a grid location in their descriptions.
A grid square narrows the search area, but it does not identify the correct floor or door by itself. Match it to the named building, key description and local landmarks. During an Order, a location objective may also appear as a marker you can ping. Check the Orders panel on the right side of the Tac-Map for the actual task and its progress.
Find the main Hajin locations
These are the expected threats listed in the official launch tour, before your own combat raises the local response. The current HUD takes priority when conditions change.
| Location | General part of Hajin | Landmarks and listed starting threats |
|---|---|---|
| 14th Political Prison | Northwest | Prison and Fortress Prison Yard: High. Y-shaped Citadel: Critical. |
| Chang-san Air Base | West | Exterior: Critical. Large underground bunker: Extreme. |
| Deadtown | Southwest | Exterior: Low. Re-Education Center: Medium. |
| Imjin Farmland | South-southwest | Farmland and Jeong Loading Dock: Low. Rice Mill: Medium. |
| Cheongun Village | North | Village, outskirts and border crossings: Low. Heavenly Luck Casino: High. |
| Mirae General Hospital | North-central | Hospital: Low in the launch tour; multiple floors and surrounding military tents. |
| Cheonwang Peak Array | Central | Medium. Elevated DBN TV station array with roof access and wooded approaches. |
| Haneul Nuclear Reactor | Northeast | Reactor: High with radiation. South Korean Border Zone: Medium. |
| NuriGO Mall | Northeast Hajin City | East: Medium. West: High. Large underground shopping area. |
| The Grid | Central Hajin City | Critical across several landmarks; Nenshin Tech Complex is listed as Extreme. |
| Songdo Wharf | Eastern Hajin City | Wharf, Oamsik Turtle Island and Shoreline Station: Low. |
| Wolves Stadium | South-central Hajin City | Stadium and Theatre: Medium. Streets include a police station and bank. |
| Hajin River Heights | Southeast | River Heights, South Island and Jinseo Park Towers: Medium. |
Prison perimeter and the Citadel
The prison has a southern checkpoint and entrance, eastern barracks and a high-walled yard. The Y-shaped Citadel inside the yard is a distinct, more dangerous structure. An objective or key for an outer storage building does not necessarily send you into the Citadel.
The Grid and the underground mall
The Grid is a fortified urban sector with rooftop engagements and limited ground-level exits. NuriGO Mall is next to it, with an extensive underground district reached around the old station courtyard. Three circular structures mark the mall entrances: a pavilion and two light wells, one containing an elevator. Night vision is useful below ground.
The reactor and air-base bunker
The reactor combines hostile resistance with radiation. Prepare suitable protection before entering it. Chang-san Air Base also extends far below its surface buildings, so a surface marker may lead into a much larger underground route. Check the mission briefing before committing to either destination.
Match building icons to the supplies you need
| Map destination | What makes it useful | Identification or limitation |
|---|---|---|
| Police Station | Military equipment and a locked armory | Predominantly blue; architectural design varies. |
| Fire Station | Radiation gear and parachutes | Red buildings; guards may be present. |
| Clinic | Medical loot | Predominantly green; other Operators may also seek healing here. |
| Gas Station | Vehicle repairs, fuel and Gas Can refills | Plan a stop when your transport is damaged or nearly empty. |
| Marine Gas Station | Watercraft repair and refueling | Usually a jetty with pumps. |
| Ammo & Armor Cache | Ammunition and Armor Plates | Often inside compounds; enters cooldown after use. |
| UAV Tower | Reconnaissance and a Side Op | Activation reveals nearby enemy and Operator positions. |
| Lieutenant Hunt tower | Nearby Lieutenant intel | Climb to the laptop; identifying a Lieutenant is separate from killing one. |
| Compound | Defended military loot and intel | A clear can become harder if a loud fight escalates. |
| SAM Site | Anti-air coverage | Capture it at the control computer and defend the process. |
| Bounty Station | Wanted Operator intel and bounty payment options | This concerns human Operator bounties, rather than a Lieutenant hunt. |
Track changing danger and extraction
Threat is local to the POI and appears under your compass. Sustained aggression can escalate the enemy response. Breaking contact, moving into cover or leaving the area can reduce that pressure. A Low label is not a promise that the area has no enemy squad.
Exfil sites are enabled from a pool of locations. Find the current marker and green smoke, call the helicopter, hold until it arrives and board. Radiation intensifies as the deployment continues, so read the timer before starting a long detour. Exfil signals are visible and audible, and other squads may use the site as an ambush.
Vehicles help cross the map but need repairs and fuel in DMZ. Gas Stations can service both ground and airborne vehicles. Keep that constraint in the route instead of treating every found vehicle as unlimited transport.
Keep launch Hajin separate from Season 1
As of October 30, Designation X01 is announced for Season 1, which is scheduled for November 6. The official Season 1 announcement describes it as a new enclosed facility reached through Hajin. Announcement footage is not a current map layer or an already available launch POI.
