The loop in one line: deploy into Hajin (solo or trio), scavenge loot and complete objectives for 30 minutes while a gas circle closes in — then reach an exfil in the final 10-minute window. Extract and you keep everything; go down and your Operator goes MIA with whatever wasn't secured.

The three mission types

TypeWhat it isWhen to run it
DMZ OrdersOpen-ended objectives that teach scavenging, crafting and FOB upgrades — an extended tutorial trackAlways available, any infil type, any time
Story missionsMulti-step narrative objectives at specific POIs across Hajin — six missions at launch, tied to MW4's post-launch storyMust be selected during infil so teams don't collide on the same objective
Dynamic OpsRandomly generated multi-step objectives that differ every matchFiller objectives while roaming — good XP between plans

The FOB: what to unlock first

The Forward Operating Base is the pre-deployment hub — loadouts, crafting, vendors and progression all live here. Some stations are open from the start; the rest unlock along DMZ's 70-level progression track.

Early priority: rush the first two DMZ Orders to open the Boss Board, then level toward the Vendor (5) and Gunsmith (10) — a tuned loadout matters more in DMZ than raw loot luck.

Rules worth knowing

30 + 10 match clock

You get 30 minutes of match time before irradiated gas floods the map, then a final 10-minute window to reach an exfil point. Miss the exfil and the run is a loss.

Notoriety marks you

Killing other players raises your notoriety level, which flags your squad's presence on the map for others to hunt. PvP is allowed — it's just never free.

Trait trees are permanent

Each Operator levels an individual trait tree granting skills and bonuses tuned to playstyles — the persistent part of progression that survives bad runs.

Weather escalates

Rain and snow roll through Hajin and intensify as the match goes on — visibility and audio both degrade late, which changes how late-game fights play out.

Secure slots save your run

Going down sends the Operator MIA along with unsecured gear — whatever sat in a secure slot comes home with you. Bank the valuables before the risky plays.

AI and players mix

Hostile NPC forces and rival squads share the zone — the PvPvE mix means every fight can draw a third party, so loud engagements are risky by design.

FAQ

Is DMZ in Modern Warfare 4 free to play?

DMZ is a mode inside Call of Duty: Modern Warfare 4, which launched October 23, 2026 on Xbox Series X|S, Xbox on PC, cloud, Battle.net, Steam, PlayStation 5 and Nintendo Switch 2. It needs the game — there's no standalone free DMZ client.

How many players are in a MW4 DMZ match?

Up to 60 players in squads of three — twenty trios sharing the Hajin exclusion zone with hostile AI forces.

Is MW4 DMZ the same as the old DMZ from MW2 (2022)?

It's the returning mode rebuilt for MW4 — same extraction DNA, but rebuilt around the FOB hub, trait trees, notoriety and Dynamic Ops rather than the original faction-mission structure.

What happens if you die in DMZ?

Your Operator goes MIA: unsecured gear is lost, while anything in secure slots extracts with you. Permanent progression — levels and traits — is never lost.
