Warfare 4 Beta: Dates, Early Access and Download

1. When is the Modern Warfare 4 Beta?

The Modern Warfare 4 Beta is divided into Early Access and Open Beta periods. Early Access begins on August 21, 2026, and runs through August 25. It is available to players who preorder an eligible edition of Modern Warfare 4 or receive a valid Early Access code.

The free Open Beta begins on August 28 and ends on September 1, allowing all players on supported platforms to participate without preordering the game.

The exact start and end times for each region have not yet been announced. Activision also notes that actual platform availability and timing may change, so players should check the official Beta page again as the event approaches. An internet connection is required, and an online multiplayer subscription may be required on some console platforms.

2. How to Get the Modern Warfare 4 Beta？

There are three main ways to access the Modern Warfare 4 Beta. You can wait for the free Open Beta, preorder a digital edition for automatic Early Access, or preorder a physical edition and redeem the code supplied by the retailer.

Option 1: Join the Free Modern Warfare 4 Open Beta

The free Open Beta starts on August 28 and is available on Xbox Series X|S, PlayStation 5, supported PC platforms, and Nintendo Switch 2. No preorder or Early Access code is required.

• Wait until the Open Beta begins on August 28, 2026. Sign in to the platform account you plan to use.

• Search for the Modern Warfare 4 Open Beta in the relevant platform store or launcher.

• Download the Beta when the listing becomes available.

• Sign in or create an Activision account if prompted.

Option 2: Preorder a Digital Edition for Automatic Early Access

Preordering a digital edition is the most straightforward way to join the Beta on August 21. Eligible digital editions are available through the Microsoft Store, PlayStation Store, Xbox on PC, Battle.net, Steam, and the Call of Duty in-game store.

• Open the official store for the platform on which you want to play.

• Select an eligible digital edition of Modern Warfare 4. Complete the preorder or prepurchase using the same platform account you will use for the Beta.

  

• Check your order history and confirm that the purchase was completed successfully.

• Download the Beta when it becomes available.

Important:

Digital customers do not need a 13-character Early Access code. Eligibility is automatically attached to the account used to purchase the game. Buying the game digitally on one platform does not automatically provide access on unrelated platforms.

Option 3: Preorder a Physical Edition and Redeem the Retailer Code

Players who preorder a physical edition through a participating retailer must register an Early Access code before they can play. The code is normally printed on the purchase receipt or included in the retailer’s confirmation email. If the code is missing, unreadable, or lost, contact the retailer that supplied it.

• Pre-order an eligible physical edition from a participating retailer.

• Find the 13-character Early Access code on your receipt, order page, or confirmation email.

• Sign in to your verified Activision account and open the official Beta redemption page.

• Enter the code, select your preferred platform, and confirm the registration.

• Wait for Activision to send the platform-specific Early Access Beta token.

• Redeem the token on the selected platform, then download and install the Beta.

⚡ Free Up Space Before Downloading the Modern Warfare 4 Beta

Activision has not yet announced the Modern Warfare 4 Beta download size or preload schedule. However, multiplayer Beta packages, shaders, launcher files, and later updates can place additional pressure on a nearly full system or game drive. Preparing storage space in advance can help prevent interrupted downloads, installation failures, and insufficient-space warnings.

Deleting a few visible files manually may not be enough because Windows can accumulate temporary installation files, application caches, system logs, and other unnecessary data across several folders. 4DDiG Partition Manager provides a Windows Clean feature that scans selected junk-file categories and helps users review and remove data they no longer need.

• Install and open 4DDiG Partition Manager. Select “Windows Clean” from the program’s navigation panel. Choose the types of files to scan. Clik “Start scan”.

• Allow the software to analyze the selected areas. After scanning, 4DDiG will display temporary files, system caches, log files, and other files that can be safely removed. Select the file categories you want to delete and click Clean to proceed.

  

• After cleaning up, the drive has enough free space to ensure a smoother Modern Warfare 4 Beta experience.
