Modern Warfare 4 DMZ Explained: Hajin Map, Forward Operating Base and the October 23 Launch

Modern Warfare 4 DMZ will launch alongside the campaign and multiplayer when Call of Duty: Modern Warfare 4 arrives on 23 October 2026, and Activision has now explained how the extraction mode works, starting with its Korean map, Hajin. Writing on the PlayStation Blog, Activision’s Daniel Noel called it “Call of Duty’s definitive extraction shooter experience”, and a separate deep dive on the official Call of Duty blog has laid out the map and the hub players will return to between runs.

How Modern Warfare 4 DMZ actually plays

DMZ is an extraction shooter, which means you deploy into a large map, complete objectives, loot what you can and then try to get out alive through an exfiltration point. In extraction modes, failing to get out usually means losing what you were carrying, which is what gives every run its tension. Activision says the mode mixes narrative missions, dynamic operations and free roam, so you can follow a storyline or simply drop in and scavenge.

The threat isn’t only computer-controlled. Hajin is patrolled by North Korean forces of different tiers, backed by armoured units, autonomous drones and helicopters, but rival squads of real players are in the same zone and can ambush you for your loot. Progression runs on its own DMZ track from level 1 to 70, separate from multiplayer ranks, which gives committed players a long-term goal beyond a single run.

Hajin is a 60-location sandbox split across two Koreas

According to the official DMZ deep dive, Hajin is a persistent, open-world zone that covers a mix of North and South Korean territory. It has more than 60 named locations spread across urban districts, military installations, farmland and industrial areas, and each area carries a threat level that climbs from low to extreme. Activision’s own advice is to move quietly in the most dangerous zones rather than go in loud, so for a squad that’s new to extraction games the sensible approach is to learn the low-threat areas first, find the exfil points you trust, and only push into the hardest zones once your loadout and progression can handle it.

The Forward Operating Base is where your progress lives

Between deployments you return to the Forward Operating Base (FOB), the command centre for loadouts and progression. Activision lists stations for Operators, your Stash and Loadout, DMZ Orders, a Firing Range, Survival Kits, a 3D Printer, the Gunsmith, a Vendor, a Bounty Leaderboard, a Boss Board, a Dog Tag Case, DMZ Progression and Deploy. The FOB also expands as you progress, and Activision says a second deep dive focused on the base is coming later this week.

What Nigerian players should sort out before 23 October

Modern Warfare 4 is coming to PS5, Xbox Series X|S, PC and Nintendo Switch 2, but not to PS4 or Xbox One, so anyone still on last-generation hardware won’t be able to play DMZ at all. That’s the same transition behind the Warzone PS4 shutdown, and it’s worth planning an upgrade now if extraction modes are your thing.

Connection quality matters more in DMZ than in a quick multiplayer match, because a disconnect mid-run can cost you everything you were carrying.

Activision hasn’t yet confirmed whether DMZ will be offered on its own outside the full game, so for now it should be treated as part of the Modern Warfare 4 purchase.
