Modern Warfare 4 does not have an announced campaign co-op mode in Activision’s current official information. The practical alternatives are to deploy together in the separate DMZ extraction mode or use two-player split-screen Multiplayer on PlayStation 5 or Xbox Series X|S. Neither option lets another player join the story campaign.
This distinction matters because Activision describes Campaign, Multiplayer and DMZ as separate modes. The guidance below reflects the official announcement, game overview and support information checked on November 13, 2026; a later update could change the feature set.

Not according to the official information currently available. Activision’s Modern Warfare 4 announcement lists Campaign, Multiplayer and DMZ independently and does not announce a second-player story mode. That is more precise than saying co-op is permanently impossible: Activision has not announced campaign co-op in the material reviewed, and a future update could theoretically add a feature.
There is no documented campaign setting, unlock, split-screen shortcut or DMZ workaround that turns the story into a cooperative mode. If your goal is to experience the scripted campaign missions with another person, the supported answer today is that you cannot do so through an announced feature.

The wording matters because a mode list is not the same as a promise that every mode shares the same player features. Campaign is presented as the story experience, while DMZ and Multiplayer are described separately. A friend joining your party, a second controller being connected or a private lobby being created does not change which mode is running. Until Activision publishes a specific Campaign co-op announcement, treat the story as a solo activity.
What does Activision actually confirm about the modes?
The official Modern Warfare 4 game page gives DMZ its own extraction-style description and says players can deploy solo or with a squad. That confirms squad play in DMZ, but it does not describe campaign missions, shared checkpoints or a cooperative story route.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Activision Support is equally specific about local play. Its editions and feature information says: “Split-screen multiplayer gameplay (two players sharing a screen) for Call of Duty: Modern Warfare 4 will be available on XBOX Series X|S and PlayStation 5.” The sentence is about Multiplayer. It does not extend split-screen to Campaign or DMZ, and it does not promise three- or four-player local play.
Activision also lists 12 all-new 6v6 Multiplayer maps at launch. That is a Multiplayer content specification, not evidence that the campaign has 6v6, co-op missions or local story support. Keeping these product details in their proper mode prevents the most common buying and setup mistake: assuming that a feature advertised for Multiplayer automatically carries over to Campaign.
Which Modern Warfare 4 modes support playing together?
The following is the clearest way to separate the documented options from the story campaign:
| Mode | What you do | Squad or local play | Important requirement |
|---|---|---|---|
| Campaign | Play the Modern Warfare 4 story | Campaign co-op is not announced in the official overview | Do not assume the Multiplayer split-screen statement applies here |
| DMZ | Enter a separate extraction experience, recover equipment and leave the conflict zone | Deploy solo or with a squad | Continuous internet is required for DMZ |
| Multiplayer | Play competitive matches, including private matches | Two-player split-screen is documented on PlayStation 5 and Xbox Series X|S | Continuous internet is required, including for Private Matches |
Activision’s game page describes DMZ as an experience where players can “deploy solo or with a squad” into a conflict zone. That wording establishes squad play, but it does not describe campaign missions, shared story checkpoints or cooperative versions of the Campaign.

Multiplayer is the other documented way to play beside someone on the same console. It remains competitive Multiplayer, even when you use a Private Match or share a television. Split-screen changes the display arrangement, not the mode’s objectives or the online requirement.
How do you play with friends in DMZ?
DMZ is the official squad-based alternative when you want to play in the same online session. It is a separate mode with its own objectives and extraction structure, so choose it only if you are comfortable playing something other than the scripted campaign.

- Use a supported version of the game. Activision’s announcement lists PlayStation 5, Xbox Series X|S, PC and Nintendo Switch 2. It says Modern Warfare 4 is not available on PlayStation 4 or Xbox One.
- Start the game and open the mode selection. Select DMZ, not Campaign. Menu wording can change with updates, but the mode must be DMZ for the squad feature described by Activision to apply.
- Bring your friends into the session. Use the game’s social or party controls, or the platform’s online invitation tools, to add the people who should deploy with you. The exact button labels can differ between console, PC and later interface updates.
- Confirm the squad before deployment. DMZ supports solo or squad deployment. If a friend has not joined the party, check the lobby before launching rather than assuming they will be added to the operation.
- Stay connected to the internet. Activision Support says continuous internet is required for DMZ. A local network session or an offline console profile is not a documented substitute.
What happens in DMZ should not be described as campaign co-op. You are entering the extraction mode, not replaying the campaign’s missions with a second character, and the official materials do not promise shared campaign progression between the two modes.
DMZ is therefore the right choice when the group wants a shared objective and is happy with an extraction loop. It is not the right choice if the group’s priority is hearing the campaign dialogue, following its scripted set pieces or preserving one player’s story checkpoints. Those expectations belong to Campaign, which currently has no announced co-op feature.

Split-screen is documented for Multiplayer only, with two players sharing one screen on PlayStation 5 and Xbox Series X|S. Activision Support does not state that Campaign or DMZ supports local split-screen, and it does not list PC or Nintendo Switch 2 for this feature.
- Check the console first. Split-screen support is specifically stated for PlayStation 5 and Xbox Series X|S. If you are on PC, Nintendo Switch 2, PlayStation 4 or Xbox One, there is no corresponding split-screen statement in the cited support information.
- Connect the second controller. Have the second player’s controller paired with the console and follow any sign-in prompt shown by the game. The support page’s specification is two players sharing a screen; it does not document a larger local group.
- Choose Multiplayer. Enter the Multiplayer section rather than Campaign or DMZ. Selecting a different mode will not expose the documented split-screen feature.
- Join the second player from the Multiplayer lobby. Use the on-screen join prompt or the console’s player-join flow. Interface labels may change, so follow the prompt displayed by your installed version.
- Select a Multiplayer activity. You can use the available public playlists or set up a Private Match. Activision Support still requires continuous internet for Multiplayer, including Private Matches, so split-screen does not mean offline play.
A second controller is therefore relevant only to local Multiplayer on a supported console. It is not a way to add a partner to the Campaign, and buying another controller will not create a campaign co-op option that the software does not document.
Before inviting someone over, check that the console is connected, the game is updated and both controllers are recognized. If the join prompt is missing, first confirm that you are in Multiplayer and not in a Campaign submenu. Do not assume that a successful local sign-in proves that the other modes support the same arrangement.
What is the difference between DMZ squad play and split-screen Multiplayer?
DMZ gives you cooperative online squad play in a separate extraction mode. Split-screen keeps two Multiplayer players on one supported console, but it remains competitive Multiplayer rather than a shared story campaign.
| Question | DMZ | Split-screen Multiplayer |
|---|---|---|
| Does it continue the Campaign story? | No; it is a separate mode | No; it is Multiplayer |
| Can people play as a squad? | Yes, solo or with a squad | Two local players are documented |
| Is local couch play documented? | No local split-screen statement | Yes, two-player split-screen |
| Where is support stated? | Activision’s official game overview | Activision Support’s editions and feature information |
| Is an internet connection required? | Yes, continuously | Yes, including Private Matches |
| What kind of session is it? | Online extraction operation | Local shared-screen Multiplayer match |
Choose DMZ when the priority is completing an operation with online teammates. Choose split-screen Multiplayer when two people are physically together at one PlayStation 5 or Xbox Series X|S and want to share a display. Choose Campaign only when the priority is the story and you are willing to play it solo.
What should a two-player household prepare?
For local Multiplayer, the practical checklist is short but important. You need a supported console, the game installed on that console, a second compatible controller and a continuous internet connection. Activision’s specification covers two players sharing one screen; it does not establish support for a third local player, a second console in the same room or an offline LAN arrangement.

For online DMZ, each participant needs access to the game on a supported platform and a reliable internet connection. Use the in-game social or platform invitation flow, then verify that every intended teammate appears in the pre-deployment party. The exact menu labels can change, so follow the prompts in the current build rather than a launch video.
Neither preparation list includes a campaign co-op purchase or unlock. A second controller, a Private Match, a DMZ party or a second copy of the game cannot convert Campaign into a two-player mode.
What should you do if you specifically want to play the story together?
There is no supported route to add a second player to the Campaign based on the official information checked. Do not rely on a DMZ invite, a private Multiplayer match or a second controller as a hidden campaign mode; each belongs to a different feature set.
Your realistic choices are to play separate campaign sessions, take turns on the same console, or use voice or screen-sharing outside the game while one person plays. Those approaches can make the experience social, but they do not create simultaneous two-player campaign control. If Activision later announces a cooperative campaign, look for a new official mode description or support entry rather than assuming that an unrelated Multiplayer update applies.
Which platforms can you use for each group-play option?
Platform support is especially important because the split-screen statement is narrower than the general game-platform list.
- PlayStation 5: Campaign, DMZ and Multiplayer are listed platform options; two-player Multiplayer split-screen is documented.
- Xbox Series X|S: Campaign, DMZ and Multiplayer are listed platform options; two-player Multiplayer split-screen is documented.
- PC: The game is listed for PC, and online modes may require continuous internet, but the cited support information does not document local split-screen.
- Nintendo Switch 2: The announcement lists the platform, but the cited support information does not document local split-screen there.
- PlayStation 4 and Xbox One: Activision’s announcement says Modern Warfare 4 is not available on these older consoles.
If you are buying a physical copy, Activision Support says physical editions are available for PlayStation 5 and Xbox Series X through select retailers. Check the platform label before purchase; availability, stock and edition details can change.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsDo not treat the broad platform list as a split-screen compatibility list. PS5 and Xbox Series X|S are the only platforms named in the support statement for two-player local Multiplayer. For PC and Nintendo Switch 2, the cited official information does not document couch co-op, so verify any later platform-specific update before buying extra hardware.
Does split-screen work without an internet connection?
No offline split-screen Multiplayer setup is documented. Activision Support says continuous internet is required for Multiplayer, including Private Matches, so a second controller and one console do not remove that requirement.

The cited support statement does not establish the Campaign’s offline requirements. Consequently, do not infer that the story can be played offline, or that an offline campaign would somehow enable a second player. Check the current support page for the exact requirements of your edition and platform.
The same distinction applies to DMZ: it is an online mode, and Activision Support lists continuous internet as required. A home network problem can therefore prevent both online squad deployment and split-screen Multiplayer, even though only the latter uses one shared screen.

How do you troubleshoot a missing co-op option?
Most confusion comes from selecting the wrong mode or using a platform for which the feature was never documented. Work through this checklist before treating a missing option as a technical fault:
- Verify the mode. Campaign will not show the documented DMZ squad or Multiplayer split-screen controls. Return to the main mode selector and choose the feature you actually want.
- Verify the platform. For split-screen, confirm that the console is PlayStation 5 or Xbox Series X|S. A PC or Nintendo Switch 2 installation may still support the game without having the documented local feature.
- Verify the connection. DMZ and Multiplayer require continuous internet according to Activision Support. Test the console or PC’s connection and retry after the service is available.
- Verify the second player’s controller. On a supported console, pair the second controller and follow the join prompt in Multiplayer. If the prompt never appears, make sure you are not still inside Campaign or DMZ.
- Check for a current update and support notice. Feature labels can change after updates. Use the official Activision Support page for the current edition and platform requirements rather than relying on an old video or forum post.
- Do not interpret the absence of a campaign option as an unlock requirement. The official sources do not describe a campaign co-op unlock, level requirement or hidden menu.
If the issue affects only one mode, compare it with the documented scope instead of assuming the installation is broken. A missing split-screen prompt in Campaign is expected under the current feature description; a missing prompt in Multiplayer on a supported console is the situation that merits checking controllers, updates and the support page.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Could a future update add campaign co-op?
It could, but the current sources do not announce one. The careful conclusion is therefore time-limited: as of the official information checked on November 13, 2026, Activision has not announced campaign co-op.
Recheck Activision’s mode announcements and support documentation after a substantial update. A genuine campaign co-op addition should be identified explicitly, with details about player count, platforms, online or local play and whether existing missions support it. Until such information appears, treat Campaign as solo and use DMZ or Multiplayer for the documented ways to play with someone else.
What access details should you check before buying?
Modern Warfare 4 is a standalone release, according to Activision’s October 2026 launch update. That update also says the game is not included with Game Pass until Holiday 2027, a date-sensitive access detail that should be rechecked before you purchase or subscribe.
More important for a co-op decision, confirm the exact platform edition and whether you need online service access for your console. The official requirements cited here establish continuous internet for DMZ and Multiplayer, but they do not provide a complete offline Campaign requirement.

If you choose a physical copy, Activision Support says PS5 and Xbox Series X editions are sold through select retailers. That statement does not verify a particular store’s stock, price, affiliate terms or edition contents. Check the platform marking and current listing yourself, especially if your plan depends on PS5 or Xbox Series X|S split-screen.
Bottom line: what is the best way to play Modern Warfare 4 with someone else?
If you want the story campaign itself, there is no announced co-op mode to start. For cooperative online play, select DMZ and deploy as a squad. For two people sharing one screen, use Multiplayer split-screen on PlayStation 5 or Xbox Series X|S, with continuous internet. Keep those options separate from Campaign, because neither one adds a second player to the story.
Frequently Asked Questions
Is there a hidden setting that unlocks Modern Warfare 4 campaign co-op?
No hidden toggle, level requirement or unlock is described in Activision’s current materials. Campaign co-op would need an explicit official announcement or support entry; a DMZ invitation or Multiplayer lobby cannot unlock it.
Can three people use Modern Warfare 4 split-screen?
Activision Support specifies split-screen Multiplayer for two players sharing one screen. It does not document three- or four-player local split-screen, so plan on two local players unless a later support update says otherwise.
Does DMZ share campaign missions or checkpoints?
The official descriptions present DMZ and Campaign as separate modes. They do not promise shared campaign checkpoints or story progression, so DMZ should be treated as its own extraction experience.
Can I play local split-screen Multiplayer completely offline?
No. Activision Support says continuous internet is required for Multiplayer, including Private Matches. Local split-screen changes how players share the screen, not the online requirement.
The Tool Desk
Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Is DMZ the same thing as campaign co-op?
No. DMZ is a separate extraction mode in which Activision says players can deploy solo or with a squad. It does not put a second player into Campaign missions or provide documented shared story progression.
The Bottom Line
Campaign is currently solo in Activision’s announced feature set. Use DMZ for online squad play, or use two-player split-screen Multiplayer on PS5 or Xbox Series X|S. Both alternatives are separate from the story, and both require continuous internet.
