Modern Warfare 4 Beta platforms include PS5, Xbox Series X|S and PC during Early Access, with Nintendo Switch 2 joining when the free Open Beta begins on August 28, 2026. PS4 and Xbox One are not supported because Modern Warfare 4 is not being released on previous-generation consoles.
The first Modern Warfare 4 beta weekend begins on August 21 at 11:00 a.m. PT for eligible pre-order players. The second weekend begins on August 28 at 10:00 a.m. PT and opens the beta to everyone on supported platforms without requiring a pre-order.
Modern Warfare 4 Beta Platforms
The Modern Warfare 4 Beta platforms differ slightly between the two beta weekends.
| Platform | Early Access August 21 | Open Beta August 28 |
|---|---|---|
| PS5 | Yes | Yes |
| Xbox Series X | Yes | Yes |
| Xbox Series S | Yes | Yes |
| PC Battle.net | Yes | Yes |
| PC Steam | Yes | Yes |
| Xbox on PC | Yes | Yes |
| Nintendo Switch 2 | No | Yes |
| PS4 | No | No |
| Xbox One | No | No |
Nintendo Switch 2 is the major difference between the two weekends. It does not participate in the August 21 Early Access period but becomes one of the Modern Warfare 4 Beta platforms when Weekend Two starts.
Is the Modern Warfare 4 Beta on PS5?
Yes. PS5 players can participate in both Modern Warfare 4 beta weekends.
Eligible players who pre-order Modern Warfare 4 can start during Early Access on August 21 at 11:00 a.m. PT.
Players who do not pre-order can wait for the free Open Beta, which begins on August 28 at 10:00 a.m. PT.
Digital PS5 pre-orders are automatically registered for Early Access and do not require a separate beta code.
Eligible physical pre-orders from participating retailers may instead provide an Early Access Beta code.
Is the Modern Warfare 4 Beta on PS4?
No. PS4 is not one of the Modern Warfare 4 Beta platforms.
Activision has confirmed that Modern Warfare 4 itself will not release on PlayStation 4.
The game launches only on current-generation consoles and PC, meaning PS4 players cannot participate in either the Early Access or Open Beta periods.
There is currently no announced PS4 version of Modern Warfare 4.
Is the Modern Warfare 4 Beta on Xbox Series X and Series S?
Yes. Both Xbox Series X and Xbox Series S support the Modern Warfare 4 beta.
Eligible pre-order players can participate from August 21, while the Open Beta becomes available to everyone from August 28.
Modern Warfare 4 also supports Xbox Play Anywhere. The full game can be purchased through Xbox Series X|S or Xbox on PC as a single eligible purchase across those current Xbox platforms.
Xbox One is not supported.
Is the Modern Warfare 4 Beta on Xbox One?
No.
Modern Warfare 4 is not being released for Xbox One, and Xbox One is not included among the Modern Warfare 4 Beta platforms.
Activision specifically confirms that Modern Warfare 4 will not be available on previous-generation Xbox One or PlayStation 4 consoles.
Xbox players need an Xbox Series X or Xbox Series S for the console beta.
Is the Modern Warfare 4 Beta on PC?
Yes. PC players can participate in both beta weekends.
Activision lists three PC routes for Modern Warfare 4:
Battle.net
Steam
Xbox on PC
Players who pre-purchase digitally through an eligible PC storefront are automatically registered for the August 21 Early Access period.
The free Open Beta then becomes available from August 28 regardless of pre-order status.
An internet connection is required to participate in the beta.
Is the Modern Warfare 4 Beta on Nintendo Switch 2?
Yes, but Nintendo Switch 2 players have to wait until Weekend Two.
Nintendo Switch 2 is not one of the Modern Warfare 4 Beta platforms for the August 21 Early Access period.
Instead, Switch 2 joins when the Open Beta begins on August 28 at 10:00 a.m. PT.
No Modern Warfare 4 pre-order is required to participate in the Switch 2 Open Beta.
Modern Warfare 4 pre-orders for Nintendo Switch 2 begin separately on August 26.
Why Is Nintendo Switch 2 Missing From Early Access?
The Nintendo Switch 2 version of Modern Warfare 4 does not open for pre-orders until August 26.
That date falls after the first beta weekend, which runs from August 21 until August 25.
Switch 2 therefore skips Early Access and enters directly into the free Open Beta on August 28.
Once Weekend Two starts, Activision describes the Open Beta as available to players on all supported platforms, including Nintendo Switch 2.
When Can Each Platform Preload the Beta?
Players eligible for Early Access can begin preloading the beta on August 20 at 9:00 a.m. PT.
That preload applies to the systems participating in Weekend One.
For Weekend Two, all players can begin preloading on August 26 at 9:00 a.m. PT across the supported Open Beta platforms.
The schedule is:
| Beta stage | Date and time |
|---|---|
| Early Access preload | August 20 at 9:00 a.m. PT |
| Early Access starts | August 21 at 11:00 a.m. PT |
| Early Access ends | August 25 at 10:00 a.m. PT |
| Open Beta preload | August 26 at 9:00 a.m. PT |
| Open Beta starts | August 28 at 10:00 a.m. PT |
| Open Beta ends | September 1 at 10:00 a.m. PT |
Do You Need to Pre-order on Every Platform?
A pre-order is only required to participate in the August 21 Early Access period.
Players who simply want to try Modern Warfare 4 can wait for Weekend Two.
The August 28 Open Beta does not require a pre-order and is available across PS5, Xbox Series X|S, PC and Nintendo Switch 2.
Digital pre-orders on eligible Early Access platforms are validated automatically. Retail pre-orders may instead require an Early Access Beta code.
Which Modern Warfare 4 Beta Platforms Get the Free Open Beta?
All supported Modern Warfare 4 Beta platforms can participate once the free Open Beta begins on August 28.
That means PS5, Xbox Series X|S, Battle.net, Steam, Xbox on PC and Nintendo Switch 2 players can play without pre-ordering the full game.
The Open Beta runs until September 1 at 10:00 a.m. PT.
PS4 and Xbox One are not supported during either beta weekend because Modern Warfare 4 is not being released for those previous-generation consoles.
