Call of Duty DMZ's New Trailer Gives You a Closer Look at Hajin's War-Torn Battlefield

Call of Duty has officially kicked off its DMZ marketing week with a new World Builder trailer, giving you a closer look at Hajin and the events that have turned the region into a war-torn battlefield. The roughly two-and-a-half-minute trailer is largely focused on the setting and story behind DMZ, while also offering several glimpses at what you can expect to encounter when you enter the map.

The trailer opens with Hajin already in rough shape, with its roads damaged and much of the population driven out by the blast. The destruction is directly related to the nuclear reactor, which plays a major role in the story. As the situation worsens, the North begins to retreat into the region, and important intelligence is received concerning its activities.

According to the information presented in the trailer, Hajin sits above a network of military facilities containing chemical, biological, and nuclear weapons. The North is believed to be searching for these weapons, but it isn't the only threat operating in the area.

Rogue operators are also active throughout the DMZ, giving you multiple groups to deal with as you explore the region.

The trailer makes it clear that the situation is larger than a simple military operation. And if the weapons are recovered, that threat may not be confined to Hajin itself. That's why the operators are sent in to locate the enemy, deal with combatants, and uncover what is happening beneath the city.

The operation is also described as being off the books, meaning the operators won't have access to unlimited resources. Instead, you'll have to find what you need yourself as you move through the DMZ. That fits the mode's extraction-based nature, where searching the environment and using whatever you find can become as important as winning a firefight.

One of the trailer's biggest highlights is Hajin itself. You get to see several different sections of the map, including its coastline, bridges, downtown streets, rooftops, highways, and more built-up urban areas. Some of these locations have already appeared in previous Call of Duty material, including areas connected to Ground War and the stadium map.

The city also appears to have plenty of verticality. Several rooftops are accessible, while zip lines connect different sections of the environment. A bridge on the right side of the city also carries a train through the area, adding another recognizable feature to the urban landscape.

Hajin doesn't look like a map built around a single environment type either.

As you move away from the dense downtown area, the landscape transitions toward hills, forests, military facilities, and other built-up sections. The map looks like it will mix urban and rural environments, so depending on where you are, you'll have different environments to play around with.

The trailer also shows Hajin in different weather and lighting conditions. One sequence is set during a rainy period with broken highways filled with derelict and destroyed vehicles. Some cars are now covered in overgrowth, highlighting how long the conflict has affected the area.

Other parts show alleyways, military checkpoints, tanks, and large government-style buildings. The roads are in bad shape, and it's raining. Ghost is seen overlooking the area from above. Even the weather seems to add to the map's overall feel, rather than just being background scenery.

Ghost watches the battlefield, rain pouring on his position, giving us yet another look at the battle raging on. His part is also vital to the trailer, where he appears intimately involved in the operation and finally becomes the lead character in one of the last sequences.

The trailer also gives you a better idea of where the nuclear reactor fits on the map. The destroyed reactor is shown to be the event that contributed to the current Hajin environment. The explosion spread destruction throughout the surrounding environment.

This top-down view of the area gives a rough idea of how the map is laid out.

The nuclear reactor is visible at the top right, with the city of Hajin below. The city is much denser and more urban. Several highways run through it. The center of the map appears to transition to hillside terrain, while more built-up areas appear toward the left and bottom-left.

An out-of-range section appears toward the top-left, while forests and damaged buildings spread around the reactor. The trailer uses these views to show how far the explosion's effects have spread. The destruction isn't limited to buildings and vehicles either.

You can see the aftermath of mass casualties, with officers dealing with captured people in some of the more disturbing sequences. These scenes help establish why the region has become so dangerous and why so many different forces are interested in what lies beneath it. Those underground facilities appear to be a main driver of the conflict.

Some of the gameplay footage also shows toxic trucks, similar to elements previously seen on the Zodiac Resurgence map. The trailer shows objects you can interact with or destroy, so you might be able to deal with threats differently depending on the circumstances.

You also get glimpses of weapon caches around the map.

The trailer reveals that weapon caches lie hidden beneath the map, with North Korean forces and rogue operators both eager to get to them. These caches and the warheads stored below Hajin seem to drive much of the fighting throughout the region.

Several locations are marked with different colors: red, blue, and green. Not sure what each marker is for yet, but it looks like the red ones are hostile zones and the others might be checkpoints or other points of interest

The variety continues outside of the city. One sequence takes place around what appears to be an oil field, with radio towers and other structures scattered across the landscape. One area even shows what looks like a small crab shack, suggesting Hajin isn't made up of only military compounds and ruined city streets.

The trailer also shows multiplayer operators moving through these locations, suggesting that the characters you've already seen elsewhere in Call of Duty will have a place in DMZ as well.

One of the more interesting parts of the footage is the way the game handles interiors. A building shown in the trailer is almost completely dark despite it being daytime outside. Floodlights are visible around the area, but the interior itself remains pitch black because the power has been knocked out.

That could create a noticeable contrast as you move through Hajin. You might walk down a bright, sunny street before entering a building where you can barely see anything. That difference could make interior combat and exploration feel very different from simply fighting outside.

The trailer also brings back night-time footage, which could become one of the more interesting elements of DMZ's gameplay. One sequence shows a squad moving through a forest during what appears to be a full night-time infiltration. Without additional equipment, visibility is extremely limited.

Flashlights and night-vision goggles could become important in these situations, especially if the night-time environment is available as an actual infiltration option. The footage also suggests that darkness may not always be handled in the same way.

A rainy or darker version of the map could produce a different experience from a completely black night-time setting.

The forest sequence is especially notable because Ghost stalks the squad from the shadows. The operators move through the area while Ghost quietly follows them before taking them out. The scene shows how different Hajin can feel depending on the conditions.

A daytime match could have you moving through a bright forest and seeing the environment clearly, while a nighttime match could turn the exact same area into a much more dangerous location. If players have access to NVGs or thermal equipment, those tools could become important parts of the way they approach these situations.

The trailer doesn't confirm every detail about how the lighting and weather systems will work during actual gameplay, but it gives you a clear look at how much the environment can change. Even entering a building during the day could potentially create a completely different situation if the power is out.

Looting also gets a brief look, with operators searching bodies and collecting equipment. That reinforces the core Modern Warfare 4 DMZ loop of moving through dangerous areas, searching for useful resources, and deciding what you can safely take with you.

By the end of the trailer, Ghost takes center stage once again.

His role seems closely tied to the DMZ operation, which is why he is so prominent in the footage. Rather than simply appearing as another operator, he seems to be one of the main figures connected to the story and the operation taking place in Hajin.

Overall, the World Builder trailer gives you a much clearer picture of what DMZ is trying to build around Hajin. You have a ruined city, military checkpoints, forests, coastlines, underground weapons facilities, damaged infrastructure, changing weather, dark interiors, and potentially full night-time infiltrations all tied together within the same region.

The story also gives the map a clear reason for its conflict. North Korean forces, rogue operators, and other combatants are all searching for weapons hidden beneath Hajin, while your operation takes place outside the official chain of command. That combination gives you plenty of reasons to explore the map while also keeping the larger conflict moving in the background.

The biggest gameplay takeaway is still the possibility of dynamic lighting and different infiltration conditions. Seeing Hajin transition from bright daylight to heavy rain, darkness, and near-total blackouts suggests that the same locations could play very differently depending on when and how you enter them.

With the DMZ marketing week now underway, this trailer is only the beginning of the information expected to arrive. For now, though, Hajin looks set to be a large, varied battlefield where the environment itself could be as important as the enemies waiting inside it.
