Call of Duty: Modern Warfare 4 Beta: What We Learned

keywords:

The Modern Warfare 4 beta is officially over, wrapping up an early access weekend from August 21-25 and an open beta that ran from August 28 to a newly extended September 1 deadline [1]. Now that the tests are complete, the full game is on track for its worldwide release on October 23, 2026, for PlayStation 5, Xbox Series X|S, PC, and Nintendo Switch 2 [2].

What happened during Beta Weekend One?

The first chance to play the game was during Beta Weekend One, an early access period for players who had pre-ordered or secured a beta code [1]. This initial test was available on PlayStation 5, Xbox Series X|S, and PC, though it didn’t include the Nintendo Switch 2 version [1]. The servers were live from 11:00 PT on August 21 to 10:00 PT on August 25, giving these players their first hands-on look at Call of Duty Modern Warfare 4.

On PC, Weekend One ran through Xbox on PC, Steam, and Battle.net [1]. It gave pre-order customers an early look ahead of the full release on October 23, 2026 [2].

What changed in Beta Weekend Two, the open beta?

The second beta weekend, starting August 28, 2026 at 10:00 PT, was a true open beta for all players, with no pre-order or code needed [1]. It ran on every confirmed platform: PlayStation 5, Xbox Series X|S, PC, and Nintendo Switch 2, which had no access in Weekend One [1]. It was also the first time a Call of Duty beta included a campaign mission [1].

The open beta was scheduled to end at 10:00 PT on September 1, but it was extended by twelve hours, to 22:00 PT [1]. The launch multiplayer is confirmed to feature 12 core 6v6 maps and modes like Gunfight and Ground War, ahead of the full release on October 23, 2026 [3].

What does the beta tell us about launch content?

The confirmed launch multiplayer includes 12 core 6v6 maps and modes like Gunfight, Kill Block, and Ground War, with named playlists such as Team Deathmatch, Domination, Hardpoint, and Search & Destroy [3]. DMZ, the extraction mode, launches alongside multiplayer as a separate mode [3].

Beta content isn’t a final guarantee of the launch-day product, and technical specs can change before release. PC system requirements are one example: as of September 21, 2026, the Activision Support page still labels the minimum specs as ‘Beta’ requirements, while the game’s Steam page lists them as ‘TBD’ [4][6]. The beta was also not limited to multiplayer: Weekend Two included a campaign mission, the first time a Call of Duty beta has done so [1].

FAQ

What is the story in the Modern Warfare 4 campaign?

The campaign kicks off with a full-scale invasion of South Korea by North Korea, starting near Hajin City [5]. The story is told from two main perspectives: one follows Private Park Hyun Jun, a young soldier caught on the front lines as the invasion begins [5]. The other tracks Captain John Price, who is hunted by his former Task Force 141 allies Ghost and Gaz [5]. As the conflict grows into a global crisis, missions will take players to diverse locations far beyond the Korean peninsula, including New York, Paris, and Mumbai [5].

Does Modern Warfare 4 have a Zombies mode?

No, a Zombies mode has not been confirmed for Call of Duty: Modern Warfare 4. The game will launch with three core modes: a single-player Campaign, a full Multiplayer experience, and the extraction-based DMZ mode [3]. Any Zombies content seen in recent Activision marketing is for a separate game, Black Ops 7, and is not part of the Modern Warfare 4 package [3].
