Modern Warfare 4’s Beta Is Doing Something Call of Duty Has Never Done Before

The beta includes a real campaign mission

The Modern Warfare 4 beta will include “Entrenched,” a short campaign mission set during the war on the Korean Peninsula. PC Gamer describes it as the first Call of Duty beta to include playable campaign content. Activision has not published a complete list of every past beta, so that “first” is best treated as the report's description of the announcement rather than a separately documented franchise statistic.

The mission follows South Korean marines and an embedded American soldier as they fight through trenches and armored-vehicle attacks. Close-range combat is a major part of the preview, with shotguns and cramped positions shaping the encounter. It is a campaign slice, not access to the full story or a replacement for the October launch.

Where it fits in the new story

Infinity Ward's campaign continues the Modern Warfare timeline after the events of Modern Warfare III. The new conflict begins when North Korea invades the South, and the player follows characters caught in a war that expands beyond the opening attack.

The official campaign material identifies Private Park as one of the new soldiers in the story. The “Entrenched” setup gives the beta a look at that side of the campaign without explaining how the larger operation develops. The full game is scheduled to launch on October 23, 2026, with digital preorder players receiving campaign access on October 16.

Why this is unusual for a beta

Call of Duty betas usually sell the multiplayer loop: weapons, maps, progression, and matchmaking. A campaign mission tests a different set of systems. It shows how the game handles scripted scenes, enemy behavior, vehicle encounters, sound, and pacing before the campaign is available to everyone.

That also changes what players can learn from the test. “Entrenched” may show the scale of the Korean conflict and the way Infinity Ward moves between soldiers, but it will not answer every story question. The mission is designed to demonstrate a piece of the campaign, not spoil the whole route from the invasion to the final operation.

When can you play it?

The mission is part of Weekend One, which begins immediately after Call of Duty: NEXT on August 21 and runs through August 25. That first period is Early Access for players who preorder any edition on Xbox Series X|S, PlayStation 5, Xbox on PC, Battle.net, or Steam.

Weekend Two runs from August 28 through September 1 and is open to everyone on the supported platforms, including Nintendo Switch 2. Activision's beta schedule does not promise that every piece of Weekend One content will remain available for the full open period, so players who specifically want “Entrenched” should plan for the first weekend.

The second weekend adds another first for the current test: Warzone content. PC Gamer reports that Zodiac Resurgence and other Warzone material are scheduled for the open period. The beta therefore moves from multiplayer and campaign content in Weekend One to multiplayer, campaign access where available, and Warzone systems in Weekend Two.

What the mission tells us about Modern Warfare 4

“Entrenched” makes the beta more useful for players who want to know how the campaign feels, not only how the guns handle. It also gives Infinity Ward a public test for a mission built around trenches, armor, and short sightlines rather than the open spaces usually shown in multiplayer trailers.

The mission cannot establish the full campaign quality on its own. One level may not represent later locations, character arcs, or the final performance. It also does not confirm whether the campaign will be longer, more open, or more connected to Warzone than previous Modern Warfare games.

“Entrenched” is still a notable change for a Call of Duty test. The beta lets players see one campaign mission before launch, then returns to the series' multiplayer focus with Kill Block, Gunfight formats, and Warzone content. The full picture will have to wait for October 23.
