Modern Warfare 4 Beta Breaks Tradition With Campaign, Multiplayer and Warzone Content

Call of Duty fans have a major reason to pay attention this week.

The Modern Warfare 4 beta begins August 21, 2026, and Activision is doing something unusual with this year's test.

For the first time in the series, the beta will give players access to a single-player campaign mission, rather than focusing exclusively on multiplayer. The mission is called “Entrenched.”

The beta will also include traditional multiplayer content, while the second testing period will add Warzone and additional large-scale gameplay.

That makes this more than a standard multiplayer beta. Players will get an early look at several important parts of Modern Warfare 4 before its full release on October 23, 2026.

Modern Warfare 4 Beta Dates

Activision has divided the beta into two weekends.

Weekend One: Early Access

August 21–25, 2026

The first beta period is available to players who have pre-ordered Modern Warfare 4.

It will be available on:

Xbox Series X|S
PlayStation 5
PC

Players who digitally pre-order the game through supported stores do not need a separate beta code for early access. Physical pre-orders can require an early-access code from the retailer.

Weekend Two: Open Beta

August 28–September 1, 2026

The second weekend removes the pre-order requirement.

That means anyone can participate, including players who have not purchased the full game.

The open beta will also expand platform availability to include Nintendo Switch 2.

This makes the second weekend the most accessible opportunity for players who simply want to try Modern Warfare 4 before deciding whether to buy it.

The Beta Includes a Campaign Mission

The biggest surprise is Entrenched, a playable single-player campaign mission.

This is important because Call of Duty betas have traditionally focused on competitive multiplayer.

Modern Warfare 4 changes that formula by allowing players to experience part of its campaign before launch.

The mission gives players an early look at the game's storytelling, combat design and campaign presentation.

It is also an interesting way for Infinity Ward and Activision to demonstrate that the campaign is an important part of the new game.

Entrenched Will Be Available During the Beta

The campaign mission isn't limited to only one testing period.

Current information indicates that Entrenched will be playable during both beta weekends.

That means early-access players can try it from August 21, while players joining the open beta can experience it from August 28.

This gives a much larger audience the opportunity to experience the new campaign content.

Multiplayer Is Still the Main Attraction

Although the campaign mission is getting most of the attention, Modern Warfare 4's beta remains heavily focused on multiplayer.

The first weekend includes multiple traditional multiplayer maps and modes.

Confirmed modes include:

Team Deathmatch
Hardpoint
Search & Destroy

Additional multiplayer content will be introduced as the beta progresses.

This should give competitive players enough variety to test the game's weapons, movement and map design.

The Second Weekend Adds Warzone

The beta becomes even bigger during Weekend Two.

Activision will add Warzone content, including a new Resurgence map called Zodiac.

This is another major change from previous Call of Duty testing periods.

Players won't simply be testing the standalone multiplayer experience.

They will also get a preview of how Modern Warfare 4 connects with the broader Warzone ecosystem.

Zodiac Is the New Warzone Resurgence Map

The new Zodiac map will be available during the open beta.

It will be used for Warzone Resurgence gameplay, giving players a chance to test the new environment and combat flow before the full game arrives.

The addition of Zodiac makes Weekend Two particularly important for Warzone players.

Ground War Also Arrives During Weekend Two

Large-scale multiplayer fans aren't being ignored.

The second beta period will introduce additional Ground War content.

Reportedly confirmed locations include Imjin Farmland and Wolves Stadium.

That gives players another way to experience Modern Warfare 4 beyond traditional small-team multiplayer.

Call of Duty: NEXT Takes Place on August 21

Another important date is August 21.

Activision has scheduled Call of Duty: NEXT for that day.

The event will feature live Modern Warfare 4 gameplay, developer information, multiplayer details and additional reveals ahead of the beta.

For Call of Duty fans, August 21 could therefore become one of the biggest information days for the game so far.

The beta begins on the same day.

Modern Warfare 4 Releases on October 23

The beta is only a preview.

The full game is scheduled to launch on:

October 23, 2026.

Activision's official beta information confirms the October release date.

That gives Infinity Ward and Activision several weeks between the beta and launch to analyze player feedback and make final improvements.

Which Platforms Will Get Modern Warfare 4?

Modern Warfare 4 is coming to current-generation platforms and PC.

The beta supports:

PlayStation 5
Xbox Series X|S
PC
Nintendo Switch 2 during the open beta

The official Xbox listing confirms the October 23 release for Xbox Series X|S and Windows PC.

The game is not being positioned as a PlayStation 4 or Xbox One release.

PC Players Have an Important Requirement

PC players should check their systems before the beta begins.

Modern Warfare 4's beta requires TPM 2.0 and Secure Boot to be enabled on supported PC configurations.

Players who haven't checked these settings should do so before August 21.

Waiting until launch day could create unnecessary problems if their system isn't configured correctly.

How to Get Modern Warfare 4 Beta Early Access

Getting into Weekend One is relatively straightforward.

Players can:

Pre-order Modern Warfare 4 through a supported digital storefront.
Install the beta when it becomes available.
Log into their Activision account.
Select the platform they intend to use.
Download the beta files.

Digital pre-orders generally include early access without requiring a separate code.

Physical pre-orders may provide an early-access code through the retailer.

The Open Beta Does Not Require a Pre-Order

Players who don't want to pre-order can simply wait for Weekend Two.

The August 28–September 1 open beta is available without a pre-order and expands access to all supported platforms, including Nintendo Switch 2.

This is arguably the best option for players who want to test the game before spending money.

Why This Beta Is Different

Modern Warfare 4's beta is unusual for several reasons.

A Campaign Mission Is Playable

The inclusion of Entrenched makes this the first Call of Duty beta to offer a single-player campaign mission.

Warzone Is Part of the Test

Weekend Two introduces Warzone content and the Zodiac Resurgence map.

Ground War Returns to the Beta

Large-scale combat will also be available during the second weekend.

Nintendo Switch 2 Gets the Open Beta

The second weekend includes Nintendo Switch 2 players, making the test broader than the first weekend.

What Players Should Test During the Beta

The beta isn't just about getting early access.

Players can use it to evaluate whether Modern Warfare 4 is worth buying.

Here are some things worth paying attention to.

Weapon Feel

Try different weapon categories and see whether the gunplay feels balanced.

Movement

Movement has become one of the most important parts of modern Call of Duty games.

The beta should give players an early impression of how Infinity Ward has approached movement this time.

Multiplayer Maps

Pay attention to sightlines, spawn locations and opportunities for different playstyles.

Campaign Presentation

The Entrenched mission should give players an early look at the game's campaign direction.

Warzone Integration

Weekend Two will be particularly useful for players who spend most of their time in Warzone.

Modern Warfare 4 Could Have a Huge Launch

The Call of Duty franchise remains one of gaming's biggest annual releases.

Modern Warfare 4 already has significant attention because of its campaign, multiplayer and Warzone integration.

The beta gives Activision an opportunity to demonstrate all three elements before launch.

If the testing period receives a strong response, it could generate even more momentum heading into October.

Samsung Is Also Partnering With Modern Warfare 4

Another fresh development announced today is a major Samsung partnership.

Samsung has become the official TV, monitor, soundbar and Wi-Fi speaker partner for Modern Warfare 4.

The partnership includes support for HDR10+ GAMING and native 32:9 super-ultrawide support.

That means players using compatible Samsung displays can take advantage of the game's expanded ultrawide presentation.

What HDR10+ GAMING Means for Players

HDR10+ GAMING is designed to improve HDR presentation by dynamically adjusting aspects such as brightness and contrast.

For Modern Warfare 4, the technology is intended to help the game's visuals remain closer to the developers' intended presentation.

It isn't essential for playing the game, but compatible hardware could provide a more advanced visual experience.

Modern Warfare 4 Is Built for Current-Generation Hardware

The game's support for 32:9 displays and HDR10+ GAMING also shows how Activision is targeting newer gaming hardware.

Players using high-end PCs and displays should have more opportunities to take advantage of the game's visual technology.

For competitive players, however, performance and responsiveness will likely remain more important than visual features.

What Happens After the Beta?

The beta will end on September 1.

That leaves several weeks before the full release on October 23.

During that period, Activision and Infinity Ward can analyze:

Player feedback
Weapon balance
Map performance
Bugs
Connection issues
Matchmaking
Gameplay statistics
Campaign reactions

The final version could therefore differ from what players experience during the beta.

Call of Duty: Modern Warfare 4's beta is shaping up to be one of the most important testing periods in the franchise's recent history.

It doesn't simply offer another multiplayer preview.

Players will be able to experience the Entrenched campaign mission, traditional multiplayer, Ground War and, during the second weekend, Warzone's new Zodiac Resurgence map.

The schedule is also easy to remember.

August 21–25: Early Access Beta for pre-order customers.

August 28–September 1: Open Beta for everyone, including Nintendo Switch 2.

The full game then arrives on October 23, 2026.

For players who are still undecided about Modern Warfare 4, the open beta could be the perfect opportunity to test the game without committing to a purchase.

And with Call of Duty: NEXT arriving on August 21, there should be even more information and gameplay footage to analyze as the beta gets underway.
