MW4 DMZ Explained: Hajin, the FOB, Bounties and MIA Rescues

DMZ is back in Modern Warfare 4 and playable now, since DMZ Early Access opened on October 20, 2026. This time it is not a beta bolted onto a battle royale. Here is how the mode actually works, and what it means if you are the person who always ends up carrying the squad's loot.

Hajin: where DMZ takes place

The setting is Hajin, a South Korean exclusion zone sealed off after the reactor meltdown in the campaign. The story picks up shortly after the campaign ends, so places you fought through as a soldier come back as ruins you loot.

It sits in a tri-border area: most of the zone is on the South Korean side, with North Korea and Russia across the line. Activision calls the region one of the largest and most ambitious environments the series has built, and names the landmarks: the irradiated Fallout reactor, a heavily secured Prison complex, what is left of Hajin City and a defended Military Base, with sealed areas, secret rooms and entrances you can only reach through water.

Two systems change how a raid feels:

• Threat levels per area. Each region carries its own difficulty, from Low to Extreme, shown under the compass when you enter. All 13 points of interest and what each one rates: the Hajin map.
• Dynamic weather. Rain, fog, wind and clear skies rotate, and Infinity Ward confirmed at TGS that weather affects what enemy AI can see and hear, not just what you can see.

What you actually do in there

You deploy as an off-the-books asset working for a CIA handler: secure military technology before hostile forces do, capture or neutralise threats, and get out. Other players are in there too, and you decide whether to work with them or kill them.

There are three ways to play a deployment:

• Story Missions. Narrative missions that carry the Modern Warfare 4 story on after the campaign, built for squads and for solo players, with more coming over time.
• Dynamic Operations. Multi-step objectives that chain into a climax, picked at deployment or started in the field, for example by answering a phone. Rather have them cleared for you? That is our MW4 DMZ Dynamic Operations boost. They pay out in care packages.
• Free Roam. Drop in, loot, hunt, leave.

Your missions arrive as DMZ Orders, and finishing a page of orders is what unlocks the next story mission. Exfil is by helicopter or skyhook, if you get that far. If you would rather have the order pages cleared without the deployments, that is DMZ story missions.

The FOB is half the game

Between deployments you sit in your Forward Operating Base. It is not a menu with a coat of paint, it is where the progression lives, and it grows visually as you rank up. Confirmed stations:

• Orders and Objectives: your active missions and the rewards waiting on them.
• Stash and Loadout: persistent storage between deployments. Each Active Duty operator has their own backpack and loadout, and the Stash size goes up as your DMZ rank goes up.
• Wallet: in-game cash. Missions and operations are the main source. Cash buys weapons and attachments, Lieutenant intel and MIA rescues.
• 3D Printer: crafting. Recipes are ingredient combinations, and rarer ingredients unlock better gear and upgrades for the printer itself.
• Gunsmith: weapons and attachments are bought with cash. The option to buy a weapon directly opens up as you work through Mission Orders and extract Weapon Manuals from Hajin. Until then you fight with what you scavenge.
• Weapon Vendor: a rotating, limited selection of specialised weapons, bought with cash and dropped straight into your Stash.
• Active Duty: your roster of operators, including the ones waiting to be rescued.
• Boss Board: intel on Lieutenants. Both boss types, and what each one drops: MW4 DMZ bosses. Pay for it here, or pull it from a Hunt Tower out in the field.
• Bounty Leaderboard: the most dangerous players currently in the zone.
• Deploy: the paid infil system, quiet on foot or loud by helicopter or plane, with the option to bring a vehicle.

All of it unlocks with DMZ XP, and there is no XP penalty for dying. A failed exfil still moves the base forward.

Operators and traits: why you will run one main

The Active Duty slot system is back. Every operator keeps their own backpack, loadout and trait tree, and the points stay with the operator who earned them. Activision has now published how deep that goes.

Each operator carries a Dog Tag, and its level is that operator's progression. It runs through 18 levels in six tiers: Steel, Bronze, Silver, Gold, Damascus and Onyx, each with a I, II and III. Every level up hands you one Trait Point. Reach Onyx III with 18 points earned and that operator is fully leveled. Your operator's level and your overall DMZ player level are separate tracks.

Those points go into three trees: Warfighter, Scout and Survivalist. There are 66 traits in total, 22 per tree, made up of six Major traits and 16 Minor ones. You unlock one trait per branch, so a single tree caps out at nine. With only 18 points before an operator maxes out, the real decision is whether you max two trees or open all three partway.

Two details that bite later:

• Once a trait is picked it is locked in. No respec, no swapping.
• The more traits an operator carries, the more expensive they are to rescue when they go down. A fully built operator is a liability as well as an asset.

Operator Prestige, and what it costs

At 18 Trait Points you can Prestige that operator. This is its own system, separate from the 1 to 55 player progression and from the 1 to 70 DMZ track, and it is tied to the individual operator.

The first Prestige asks for all of this at once: two weapons at Rare or better with three attachment slots each, a Rare plate carrier, a Rare backpack, four Rare printer ingredients, and DMZ cash. All of it is consumed, and the operator's traits are reset to nothing.

What you get back is a random permanent Prestige Trait, bound to that operator for good, even if you dismiss them, move them to another slot or change their skin. An operator can hold up to three.

That is the honest shape of it: the grind to Onyx III, then a deliberate wipe to keep one random perk forever. Prefer to skip the grind to Onyx III? Our DMZ operator leveling farms the XP and the trait points, and it raises the Stash size with the rank. The reset itself, with the cash and the rare items it consumes, is Operator Prestige.

MIA: losing an operator is not a wipe

When an operator does not make it out, they go MIA. You then spend in-game cash at the FOB to send a rescue team after them, and their progression continues instead of starting over. The more progress that operator carries, the more the rescue costs, and Infinity Ward's example at TGS was a 3,000 dollar bill.

The gear they went down with is gone. The trait progress is what the rescue saves. There is also a new Tourniquet, which patches you to a wounded state if you are not running self revive, enough to buy a moment, not enough to win the fight.

If the operator is worth it and the Wallet is empty, that is exactly what MIA rescue and DMZ cash are for.

Bounties and notoriety, the part that will decide lobbies

PvP is the spine of DMZ this time. Kill rival operators and your notoriety rises, which makes you easier to track and puts a price on your head. Rival squads collect by killing you and extracting with your dog tags, and the same works in reverse: hunt bounty targets, extract with their tags, get paid, and take some of the heat off yourself. Both sides have leaderboards.

Two details worth knowing:

• Notoriety is tied to the operator, not your account. An aggressive operator in one slot does not drag your quiet looter into the same mess.
• Proximity chat is back and rebuilt, with distance falloff, directionality and reverb. You will hear the squad that is about to third-party you, if you are listening.

That loop is bounty hunting and notoriety if you want it run for you.

Lieutenants and the Hundred Spirits

The zone is held by a faction called the Hundred Spirits, and their Lieutenants are the mini bosses. Infinity Ward confirmed at TGS that Lieutenants are hired foreign fighters played by operators from earlier Call of Duty games, and named Roze and Bale as examples, with the warning that they are very tough.

Kill one and they drop dog tags that populate your Boss Board once you extract with them, which also makes you a target for every squad that wants those tags. Lieutenants carry their own customised weapons, attachments and camo finishes included.

The AI around them scales too. Easy, medium and hard are the published difficulties, and Infinity Ward added at TGS that there is a fourth state: cause enough chaos and you get marked for elimination and hunted until you leave. Push into an area and the faction pushes back with reinforcements, up to attack helicopters.

Want the Boss Board cleared? That is Lieutenant boss hunts. The Commanders above them, the Colossus, the Deathstalker and the battle tank, are Commander takedowns.

What is still open

• The post-launch plan. Infinity Ward says there is a solid one and that new stories and content are coming, but the roadmap is not public.
• The exact economy. Cash rates and XP curves are being worked out by players rather than published, so anyone quoting precise figures this early is estimating.
• The sealed Russian border area, which is not reachable at launch and arrives in a later season.
• How much of the old Al Mazrah DMZ carries over in spirit. Faction rep, keys and weapon cases as you knew them are not part of what has been shown.

We update this guide when those land, not a week later.
