MW4 DMZ / FIELD NOTES
MW4 DMZ: 17 things the devs just confirmed, and what they mean on the ground
Infinity Ward spent an afternoon answering questions on the DMZ subreddit, and Westie pulled seventeen new details out of it. Some are small. A few change how you will play your first week in Hajin: how healing works, how far a parachute gets you, and whether a solo player gets a solo lobby. Early access opens on 20 October, so here is everything, sorted into what matters in a raid and what matters later, with our notes on where Wing Mait fits.

The biggest change: things now stick
Asked what separates this DMZ from the 2022 beta, the devs named three things: the Forward Operating Base, the permanent stash and dedicated progression for the mode. Everything else in this list hangs off those. In the beta, looting meant very little and dying meant very little. You lost a kit, grabbed another operator and went again. Now loot feeds the 3D printer, the printer feeds your FOB upgrades and gear, and an operator killed in a raid goes MIA with their progression intact, waiting to be rescued. Westie's read, and ours, is that this is the original vision finally landing rather than complexity for its own sake: the beta shipped with what the team could build for Modern Warfare 2 at the time, and the stash and progression were always meant to be there. The practical upshot is jeopardy. Every raid now has something riding on getting out of the exclusion zone alive, which is exactly the moment a second pair of eyes earns its keep.
Healing: wounds, tourniquets and why the medkit is king
This is the one to learn before you deploy. Auto-healing, the beta's default, is gone as your main recovery. Max health in DMZ is 150, and recovery works in states: Tourniquet. Every operator deploys with one, and it works as a self-revive. From last stand it gets you back on your feet, but only to 100 health, with a wound. Wounded. At 100 you stay wounded until you deal with it. While wounded, the tourniquet will not work again: it only becomes usable once you are back to full health. Go down a second time while wounded and you need a teammate. Bandages. These push a wounded operator back up to 150, but only for a few moments. The wound is still there, so health drains back to 100. Medkit. The only item that takes you from wounded back to 150 and keeps you there. There are also proper self-revives to loot in raid, and you can print them at the FOB and pack them before you deploy. Health now needs managing alongside armour, as it does in most extraction shooters. The rule of thumb: a tourniquet buys you one get-up, a bandage buys you a few seconds, a medkit buys you your life back. Carry medkits.


Parachutes are no longer a free escape
In the beta, the chute was Warzone's: cut, repull, use forever. After a year of testing with that version, the team found it made exploring Hajin feel less intense, because a rooftop was never really a commitment. So the base parachute is now limited-use. You will find them in places like fire stations, and there are infinite-use parachutes to find too. Both kinds can be printed at the FOB, and it is a safe bet the infinite-use version will want rarer materials. Westie's prediction for himself is a familiar one: jump off a building, forget the chute is already spent, and fall with style towards the concrete. Count your chutes before you go up.
Sixty players, twenty squads
At launch Hajin holds up to 60 players per match, 20 teams of three, the same count the beta ran on Al Mazrah. Hajin is a bigger map than Al Mazrah, so the density should feel the same or lighter. Proximity chat is back, now with directional audio. Westie, with thousands of beta hours, never found 60 too many: some raids pull everyone into the same fight, others pass with barely a squad in sight, and plenty of teams would rather talk than shoot. That social side is what DMZ did better than anything else in 2022.


Solos, duos and the matchmaker
This one is the most important line in the Q&A for anyone who plays alone, and it is not the answer many hoped for. As read out by Westie, the devs said: "In DMZ, matches are built with the direction of putting solos with solos, duos with duos, and trios with trios. However, there is no guarantee." Players can still truce, betray or assimilate in game, with assimilation capped at four players in total. For solos specifically, the team points to the tourniquet and the stealth meter as mechanics that make solo play richer. So a solo can land in a trio lobby. Westie calls it a step back from earlier messaging, and it may simply be about keeping one large player pool so matches start quickly. Either way, solo DMZ means three-player squads with three sets of eyes and comms against your one, at least some of the time. That gap is the whole reason Wing Mait exists. A squadmate that reads your map and calls what it sees does not fix the numbers, but it does mean you are not the only one watching. DMZ support is in development; what the stealth meter and the new health states look like on the HUD is high on our list to study once early access opens.
Choosing your raid
There is no separate party finder this time. Intent lives in the matchmaking flow instead: you pick Story Missions, Dynamic Ops or Free Roam, and the matchmaker groups you with players who chose the same. If you want a quiet looting run, say so at the start and you are more likely to share the server with people who want the same.

Weather yes, night no
No night mode is planned for launch, and there is no day and night cycle. What Hajin does have is dynamic weather: sun, cloud, rainstorms, fog and mist, and snow. Night vision goggles are in the loot pool for the darker parts of the map. For us that is good news. The compass strip and the location name on the DMZ HUD are printed text, and printed text reads the same in rain as it does in sun.
Inventory on a controller
Plenty of players worry how a full backpack system will feel on a pad. The devs say there is a drag-and-drop system for mouse and keyboard and a quick-action system for controller: equip, drop or stow with a single button. Item information never overlaps the inventory, the backpack sits on the right of the screen, and much of the looting UI is translucent so you can see what is moving around you while you loot. The clips so far look well refined; the real test is the first panicked loot at a contested crate.

The Serpentine question
The beta's Serpentine camo, the oil-slick reward at the end of a long chain of item collections, buy station conversions and challenges across every map, is a fond memory for a lot of players. The devs say they have plans for something similar in the post-launch seasons. No name, no date, but the Easter egg hunt is coming back in some form. The separate DMZ camo grind, with its own set of camos, switches on when early access opens.
Post-launch: X01 and a Russian landmass
Two things are confirmed for after launch. First, the X01 map arrives very soon after launch and sits in the lineup the way Building 21 did in the beta. Second, Season 2 opens a Russian landmass on Hajin. It is already there on the map but stays locked at launch, and when it opens it brings its own story, missions and Dynamic Ops. With it, Hajin becomes the largest map Call of Duty has made. More maps are promised beyond that. Our interactive Hajin map will grow with it.

Quick fire
Party FOB. When you party up, the FOB looks like the party leader's progression, but every station you use shows your own progression and your own items. No skin toggle. Not needed: DMZ lives inside Modern Warfare 4 rather than Warzone, so operators from older games are not in it. Tac sprint on. Enabled by default, unlike multiplayer. The energy drink, the stim shot and smelling salts refill and extend stamina. Own weapon tuning. DMZ damage is tuned separately from multiplayer and Warzone, built around the armour in the mode such as plate carriers. No AP or Stopping Power field upgrade. Not at launch, at least. Reconnect. Crash or disconnect and you can rejoin, as long as the server is running and the match has not ended.
Anti-cheat
Ricochet is active in DMZ with the work done for Modern Warfare 4: server-side culling, TPM 2.0, Secure Boot and stronger account security. The beta had a real cheating problem, and Westie is frank that his confidence is low; with DMZ now part of a paid game, everyone is hoping for cleaner lobbies. Since people ask: Wing Mait does not read game memory, inject anything or send inputs. It reads the picture on your screen, the same pixels you see, and talks to you about them.
Long-term support
The last question was the big one: will DMZ outlive Modern Warfare 4? The devs did not commit, but they did say this, as read out by Westie: "We have big plans for post-launch and we are testing the early seasons of content right now. It's too early for us to make any sweeping commitments, but we can say we have plans to support DMZ and evolve the mode." They added that they will be watching player feedback closely. Make of it what you will. We read it as a team that wants to stay, and is waiting to see if the players do too. See you in Hajin on the 20th.
