COD: MW 4 Everything you need to know about Revamped DMZ
Activision and Infinity Ward have revealed the first comprehensive look at the updated DMZ extraction mode for Call of Duty: Modern Warfare 4. Set in the high-stakes Exclusion Zone of Hajin, this iteration builds directly on the open-world survival loop by introducing persistent base building, dedicated Level 70 progression, and high-density points of interest (POIs).
What is the Hajin Exclusion Zone?
Hajin serves as Modern Warfare 4‘s primary open-world DMZ deployment zone. Designed as a high-risk sandbox, players infiltrate the map to gather loot, eliminate hostile AI forces, fulfill faction orders, and extract safely while warding off rival squad Operators.
Key Points of Interest (POIs) across Hajin:
14th Political Prison: A heavily fortified Citadel complex tucked behind dense woodlands, ideal for high-tier loot runs.
Haneul Nuclear Reactor & Cheonwang Peak Array: Technical hubs featuring long sightlines and elevated perches for sniper combat.
Mirae General Hospital & NuriGO Mall: Dense urban structures offering room-to-room CQB engagements and medical/tech supplies.
Chang-san Air Base & Wolves Stadium: Open combat zones packed with dynamic air and ground vehicle spawns.
Songdo Wharf & Hajin River Heights: Maritime transit routes tailored for watercraft extractions.
Expanding Your Command: The Forward Operating Base (FOB)
Unlike previous iterations where gear management was largely menu-based, Modern Warfare 4 introduces an evolving hub called the Forward Operating Base (FOB). As players complete deployments and accumulate resources, the base expands from a basic foothold into a full military enterprise housing over a dozen specialized stations:
| Station | Function |
| Operators (Active Duty) | Manage squad rosters, track status, and apply permanent Operator Traits. |
| 3D Printer | Craft equipment, attachments, and base upgrades using extracted materials. |
| Gunsmith & Vendor | Construct custom weapons via extracted manuals or purchase daily rotating gear. |
| Bounty & Boss Boards | Track top PvP players or buy intel to hunt high-value AI Lieutenants and Commanders. |
| Stash & Survival Kits | Store extracted components, weapons, and special thematic loot kits. |
Leveling Up: DMZ Progression and Gameplay Loop
Progress in DMZ now operates on a dedicated Level 1 to 70 progression track, separate from standard multiplayer ranks. Players gain DMZ XP across three core pillars: Combat, Looting, and Objectives, working toward an S-Tier deployment rating at extraction.
Core In-Game Systems
Dynamic & Side Operations: Field-initiated missions accessible via radios scattered around Hajin that reward scaling supply drops.
DMZ Orders: Narrative-driven mission chains that guide new players while offering high-level blueprints and recipes to veterans.
3D Crafting Economy: Extracted ingredients can be converted at the FOB 3D Printer to create rare gear or permanently upgrade base utility.
