Call of Duty: Modern Warfare 4 is getting an open beta before its full launch on October 23, 2026. The beta gives players an early look at multiplayer and helps Activision improve the game. If you are searching for how to download the MW4 beta, the process depends on your access.
The first beta weekend runs from August 21 through August 25 for players who pre-ordered or pre-purchased the game. The second weekend begins August 28 and runs through September 1. This period is open to everyone, so a preorder is not required.
How To Download The MW4 Beta
The process remains simple across all supported platforms.
If you bought the digital version of Call of Duty: Modern Warfare 4 through an official platform, you do not need to find a separate beta download or enter a code. Your beta access is linked to the account used for the purchase.
Follow these steps:
- Open the digital store for your platform.
- Sign in to the account used for your Modern Warfare 4 purchase.
- Search for Call of Duty: Modern Warfare 4 and check the available beta content.
- Download the beta when it becomes available for your account.
- Install the required files and launch the beta through the relevant platform.
- Sign in with your Activision account if prompted.
Digital preorders through the Microsoft Store, PlayStation Store, Battle.net, Steam, and Xbox on PC are automatically registered for early access. You should not wait for a separate email containing a code.
How To Use A Beta Code
Physical preorders from participating retailers work differently. In that case, you normally receive an early access code on your receipt or through an online order email.
If you have a code, sign in to your Activision account and redeem it through the official Call of Duty beta redemption page. After successful registration, you will receive an early access beta token close to the start of the beta. The token can also appear through the redemption page.
Remember that a code is tied to the platform you select during registration. If you choose PlayStation 5, for example, you cannot assume the same code will unlock the beta on another platform.
When Can You Play The Beta?
The schedule is important because early access and open access are separate periods.
- Early Access Beta: August 21 to August 25, 2026
- Open Beta: August 28 to September 1, 2026
- Full game launch: October 23, 2026
During the second weekend, players on supported platforms can join without pre-ordering. Nintendo Switch 2 players are also included in the open beta weekend, while early access is available on Xbox Series X|S, PlayStation 5, Battle.net, Xbox on PC, and Steam.
What About PC Players?
PC players should check their security settings before the beta begins. Call of Duty: Modern Warfare 4 requires TPM 2.0 and Secure Boot on PC. These settings can prevent the game from launching if disabled.
Leave enough free storage for the beta and required updates. Activision may provide additional installation details before launch, so checking the game launcher is worthwhile.
Can You Download The Beta For Free?
The open beta does not require a preorder during the August 28 to September 1 window. That means players can join without buying the full game beforehand. Early access, however, is reserved for eligible preorders or players with qualifying beta access.
Avoid unofficial websites offering “free MW4 beta downloads.” Beta files from unknown sources can be unsafe, outdated, or modified. Use your platform’s official store and the official Call of Duty game listing instead.
