The Call of Duty: Modern Warfare 4 Beta is almost here, with Early Access beginning on August 21, 2026. Players will soon get their first major opportunity to experience Modern Warfare 4 before its full launch later this year.
With two separate beta periods, multiple platforms and different access requirements, here's everything you need to know about the MW4 Beta, including dates, early access, beta codes and how to get involved.
When Does the MW4 Beta Start?
The Modern Warfare 4 Beta is being split across two periods.
MW4 Beta Early Access
August 21 – August 25, 2026
Early Access begins on August 21 at 11:00 AM PT and runs until August 25 at 10:00 Jack WhottonAM PT.
This first period is intended for eligible players with Early Access, including qualifying pre-orders and beta access.
MW4 Open Beta
August 28 – September 1, 2026
The second beta period begins August 28 at 10:00 AM PT and runs until September 1 at 10:00 AM PT.
Unlike the Early Access period, the MW4 Open Beta does not require a pre-order and will be available to eligible players across supported platforms.
How Do You Get MW4 Beta Early Access?
Players looking to start playing on August 21 rather than waiting for the Open Beta will need eligible Early Access.
One method is pre-ordering or pre-purchasing a qualifying version of Modern Warfare 4.
Players may also obtain promotional MW4 Beta Access Codes where available.
Once redeemed correctly, an eligible beta code provides access to the appropriate Early Access period without requiring players to wait for the public Open Beta.
Where Can I Buy an MW4 Beta Code?
Players looking for an MW4 Beta Code can check CODSKINS for current availability.

Availability is limited and may change as the Early Access launch approaches.
How Do I Redeem an MW4 Beta Code?
If you've obtained a Modern Warfare 4 Beta Access Code, make sure you redeem it using the applicable Call of Duty redemption process.
Follow the redemption instructions supplied with your code and ensure you're using the correct Activision/Call of Duty account.
Your gaming platform should also be correctly linked to the account where required.
We recommend redeeming your code before Early Access begins rather than waiting until the beta has already started.
Which Platforms Support the MW4 Beta?
The Early Access Beta supports:
-
Xbox Series X|S
-
PlayStation 5
-
PC via Battle.net
-
PC via Steam
-
Xbox on PC
The subsequent Open Beta expands access further, including Nintendo Switch 2.
Always check the latest official platform requirements before attempting to redeem a beta code.
What's Included in the Modern Warfare 4 Beta?
The MW4 Beta is more substantial than a simple multiplayer test.
Players will get the opportunity to experience selected Modern Warfare 4 multiplayer content, including maps and modes ahead of launch.
Modern Warfare 4's beta also introduces something particularly interesting for Call of Duty fans: access to campaign content during the testing period.
This gives players an opportunity to experience more of MW4 than has traditionally been available through a Call of Duty multiplayer beta.
The later Open Beta period will also expand the experience further with Warzone content, giving players another reason to return for the second weekend.
When Does Modern Warfare 4 Release?
The full version of Call of Duty: Modern Warfare 4 launches October 23, 2026.
The August Beta therefore gives players an opportunity to experience the game approximately two months before release while providing feedback ahead of launch.
Players purchasing eligible digital versions of the game can also receive Campaign Early Access beginning October 16.
MW4 Monster Energy Rewards Are Coming Too
The Beta isn't the only Modern Warfare 4 promotion worth watching.
A new Call of Duty: Modern Warfare 4 x Monster Energy promotion is also arriving, bringing promotional MW4 content and rewards.
CODSKINS is tracking the latest information surrounding the promotion and has created a dedicated guide covering MW4 Monster Energy codes and rewards.
