Call of Duty: Modern Warfare 4 Beta Confirmed for August 21 with First Ever Campaign Mission Entrenched

Activision and Infinity Ward just confirmed the most ambitious Call of Duty beta in the series history. Call of Duty: Modern Warfare 4 will run an early access beta from August 21 through August 25, followed by an open beta from August 28 through September 1, and for the first time ever a single-player campaign mission will be playable during the pre-launch window. Xbox CEO Asha Sharma broke the news on X with a short teaser video for the mission, called Entrenched, and CharlieIntel confirmed the full schedule within minutes.

What is actually in the Modern Warfare 4 beta

Early Access weekend one runs August 21 through 25 and is locked behind a pre-order on PC, PlayStation 5, or Xbox Series X|S. Pre-order buyers get six multiplayer maps: Rooftops, Silkworm, Transit 213, Cachette, Lotus, and Kill Block, plus a rotation of standard modes. The campaign mission Entrenched is the headline addition and it ships on both beta weekends, so even open beta players can see how Infinity Ward is handling the Korean peninsula setting described in the Steam store blurb. Weekend two swaps Lotus out for Lithium when the open beta kicks off on August 28, and that is also when the brand new Warzone Resurgence map, called Zodiac, drops for the first time.

Nintendo Switch 2 players are not left out either. The open beta weekend is the first time Modern Warfare 4 has been playable on Switch 2 hardware, which fits the broader Activision strategy of supporting Nintendo's new console alongside the usual PC, PlayStation 5, and Xbox Series X|S lineup. Anyone who buys the game on Switch 2 will get a free upgrade path from the cartridge release and the same content as everyone else at launch.

Launch date and what Call of Duty: NEXT brings

Call of Duty: Modern Warfare 4 launches October 23, 2026, and the pre-release hype train starts one week earlier on August 21 with the official Call of Duty: NEXT broadcast. NEXT is where Infinity Ward plans to show off full multiplayer gameplay, walk through the new progression system, and reveal more of the campaign before the early access beta kicks off. Asha Sharma framed Entrenched as a deliberate choice to put a chunk of the campaign in front of players before they buy, which is unusual for a series that has historically treated single-player as a launch-day surprise.

The beta being this content-rich also answers a question fans have been asking since the game's reveal: is this another Black Ops 7 situation where the campaign is basically a co-op afterthought? Activision and Xbox are clearly betting that dropping Entrenched into the beta will pull lapsed single-player fans back in. The official Steam listing tags Modern Warfare 4 as Action, Shooter, FPS, and First-Person, and lists Infinity Ward as the lead developer alongside Beenox, Raven Software, Treyarch, Sledgehammer Games, High Moon Studios, Digital Legends, and Activision Shanghai.

Community reaction so far

Reaction across gaming Twitter is mixed but engaged. The official Call of Duty post about Entrenched pulled in over 14 million views and 1 million reposts on the lead-up tweet alone, and CharlieIntel noted that the big question on everyone's mind is visibility, specifically whether muzzle smoke and visual clutter that plagued earlier Infinity Ward entries have been cleaned up. CharlieIntel also floated the idea of a DMZ beta before launch, given that DMZ is shipping as part of the paid Modern Warfare 4 game this year instead of being bundled with Warzone, and over 300,000 people voted in the poll within the first hour.

Kotaku framed the bigger story as Activision Really Wants You To Know Call Of Duty: Modern Warfare 4 Is Not A Horrible Mess Like BLOPS7, leaning into the contrast with last year's troubled launch. That kind of pre-launch defensive positioning is rare for the publisher, and the fact that they put a campaign mission in the beta instead of just hiding it tells you where their confidence sits. Pre-order numbers are not public yet, but with 1 million reposts on the lead tweet and 6 million likes on the main beta announcement, the marketing push is clearly working.

Why the early access split is annoying and fair at the same time

Splitting the beta into a pre-order early access window and then a four-day open beta is the standard Activision play, and it is exactly the kind of thing that makes players grumpy. Pre-ordering is the only way to play Entrenched during weekend one, and the same maps and modes you get during early access are not what the open beta gets, since Lotus is swapped for Lithium when the gates open to everyone on August 28. You also have to pre-order to play Entrenched during the open beta, per the official Xbox wire, which means casual players will get multiplayer, Warzone Zodiac, and a few modes, but they will not get the campaign mission unless they buy in.

That said, putting Entrenched in any form of beta is a real concession. Past Call of Duty betas have been multiplayer-only and the campaign has always been a black box until launch day. The fact that Activision is willing to let players rip into a single-player mission five weeks before release tells you the studio is more confident in this build than they have been in years. It also gives them a chance to gather telemetry on difficulty, pacing, and the visibility complaints that have dogged recent Infinity Ward releases before the October 23 ship date.

The CriticalPixel take

Modern Warfare 4 is shaping up to be the first Call of Duty launch in a long time where the publisher is actively trying to win back lapsed fans instead of just mailing in another yearly entry. The Korean peninsula setting is a return to grounded modern warfare after the near-future Black Ops arc, and dropping a campaign mission into the beta is a quiet admission that single-player still matters. If visibility and gunplay are clean when the early access beta kicks off on August 21, this has a real shot at being the strongest Modern Warfare launch since the 2019 soft reboot. Pre-order if you want Entrenched on day one, otherwise wait for the open beta on August 28 and decide from there.
