Modern Warfare 4 Open Beta Dates Set for August

Infinity Ward has locked in two Modern Warfare 4 beta weekends in late August, giving players a clear window to test multiplayer ahead of the game’s October 23 launch. The split between pre-order early access and a fully open weekend matters now because it shapes who gets hands-on time first—and what feedback the studio can use to refine the experience.

What happened: two Modern Warfare 4 beta weekends

Call of Duty: Modern Warfare 4 has confirmed its open beta schedule, with an early access period followed by a broader public test. Weekend one runs from August 21 to August 25 and is limited to players who pre-ordered the game. This early access beta will be available on Xbox Series X/S, PlayStation 5, and PC.

Weekend two is the open beta, scheduled for August 28 to September 1. Unlike the first weekend, it is not tied to pre-orders, meaning any eligible player can jump in during the public window. The open beta expands platform support to include Nintendo Switch 2 in addition to Xbox Series X/S, PlayStation 5, and PC.

Infinity Ward also outlined what players should expect during the beta. The test is designed to let participants try multiplayer maps and modes, including a newly introduced mode called Kill Block. Additional multiplayer content named for the beta includes Search & Destroy and the Training Mobility Course. The studio also confirmed the presence of new Operators, along with 19 different weapons for players to trial.

There’s also a key access requirement: the beta will require an internet connection. For Nintendo Switch 2 players, participation will require a Nintendo Switch Online subscription.

Why it matters: early feedback, platform reach, and mode pressure

This schedule is strategically timed ahead of Modern Warfare 4’s October 23 release, giving Infinity Ward a structured way to measure player reactions before launch. By gating weekend one to pre-orders, the studio effectively gathers early technical and gameplay feedback from a committed audience, then broadens the test in weekend two to capture wider impressions.

Platform coverage is another major factor. The open beta’s inclusion of Nintendo Switch 2—paired with a Nintendo Switch Online requirement—signals Infinity Ward’s intent to test performance and matchmaking across more hardware configurations before launch.

The mode lineup also adds pressure on the studio’s iteration process. Infinity Ward previously faced criticism around the Kill Block mode, and the developers have pledged improvements to enhance the gameplay experience. Because Kill Block is explicitly mentioned as part of the beta’s playable content, players should treat the open beta as the clearest opportunity to see whether those promised changes translate into a better in-match flow.

Infinity Ward has also tied the beta lead-in to a bigger reveal moment: the studio confirmed a Call of Duty: NEXT livestream on August 21, intended to show more of Modern Warfare 4’s multiplayer ahead of the first beta weekend.

What to watch next: rewards, Switch 2 timing, and pre-launch milestones

Infinity Ward says more information about beta rewards and the exact schedules will arrive in the coming weeks. That means players planning their participation—especially those focused on progression or unlocks—should keep an eye on further announcements between now and the late-August start.

There’s also a console-specific milestone that lines up with the beta window. The game has confirmed a Nintendo Switch 2 pre-order date of August 26, placing it immediately before the open beta begins on August 28. This timing could influence how quickly new Switch 2 players move from pre-order to hands-on multiplayer.

Beyond multiplayer, Modern Warfare 4 has additional early access plans. The campaign early access is scheduled for October 16, but it will be limited to pre-order holders. That sets up a two-stage pre-launch experience: multiplayer testing in August, followed by campaign access in mid-October—allowing the studio to collect feedback on different parts of the game at different points in the build.

Practical takeaways for players

• Mark your calendar: early access runs August 21–25, while the open beta runs August 28–September 1.
• If you pre-ordered, you’ll get first access on Xbox Series X/S, PS5, and PC; otherwise, plan for the open beta.
• Expect multiplayer variety: Kill Block, Search & Destroy, and the Training Mobility Course are specifically mentioned for the beta.
• Nintendo Switch 2 players should note the need for Nintendo Switch Online, and the beta still requires an internet connection.
• Follow the August 21 Call of Duty: NEXT livestream for more multiplayer details before the beta begins.

Expert View

Locking in a two-weekend beta with a pre-order gate and then a fully open follow-up is the right move for a game that’s generating big expectations. It also puts Infinity Ward under a spotlight: Kill Block is already a known point of contention, and the beta is the first place most players will be able to judge whether the promised improvements actually land. If the studio uses the open weekend’s broader data effectively, Modern Warfare 4 could come out of this cycle with a clearer, more stable multiplayer identity—especially across mainstream and Nintendo Switch 2 audiences.
