MW4 Beta Release Date
The MW4 Early Access Beta started on August 21, 2026, at 11:00 AM PT and runs until August 25 at 10:00 AM PT. This first weekend is designed for players with eligible early access.
The second MW4 Open Beta begins on August 28 at 10:00 AM PT and ends on September 1 at 10:00 AM PT. Unlike the first weekend, everyone can join the open beta.
Do You Need an MW4 Beta Code?
An MW4 beta code is not required if you digitally pre-ordered or pre-purchased the game. Early access is automatically linked to your account.
Physical pre-orders are different. Players normally receive an MW4 beta code from their retailer. It may appear on a receipt or arrive through email.
How to Redeem an MW4 Beta Code?
Players who receive an MW4 beta code can redeem it through the official Call of Duty redemption page. After registration, an Early Access token is sent to the registered email address.
This makes the MW4 beta code especially useful for physical pre-orders and promotional giveaways.
MW4 Open Beta Is Free
The biggest advantage of the second weekend is that you do not need an MW4 beta code. Activision says the Open Beta is available to all players without a pre-order.
Players can also preload the Open Beta starting August 26 at 9:00 AM PT.
MW4 Platforms
The MW4 beta is available across supported current-generation platforms. These include PS5, Xbox Series X|S and PC through supported storefronts. Nintendo Switch 2 joins during Open Beta Weekend Two.
What the MW4 Beta Includes?
The MW4 beta focuses on multiplayer gameplay. Players can experience traditional modes, new gameplay systems, weapons, maps and the Kill Block mode. Search and Destroy is also confirmed for the beta.
MW4 Full Release Date
The full MW4 release date is October 23, 2026. The game is being developed for current-generation platforms, with Nintendo Switch 2 also supported.
Final Verdict
For players who already have an MW4 beta code or qualifying pre-order, Early Access is already available. Everyone else can join the MW4 Open Beta from August 28 without purchasing the game first.
With the full release scheduled for October 23, the beta offers the first major opportunity to test MW4 multiplayer before launch.
