Modern Warfare 4 Open Beta: Dates, Early Access, Preload, Platforms and How to Join

The Modern Warfare 4 beta begins on August 21, 2026, giving players their first public opportunity to test Infinity Ward’s new multiplayer before the full game launches on October 23.

Activision has divided the test into two periods. Eligible pre-order customers get the first opportunity to play, while the second period opens the servers to everyone on supported platforms. Nintendo Switch 2 players will only be included in the free weekend.

Several important details remain unconfirmed. Activision has not announced the beta’s exact start times, preload schedule, download size, complete map list or progression cap. This guide separates confirmed information from details that are still pending.

Modern Warfare 4 beta dates at a glance

The early-access period begins immediately after the Call of Duty: NEXT presentation on August 21. Activision has not announced the broadcast time, so the opening date should not be treated as a guaranteed full day of play.

Who gets Modern Warfare 4 beta early access?

Early access is included when you pre-order or pre-purchase an eligible edition on PS5, Xbox Series X|S, Xbox on PC, Steam or Battle.net.

Both the Digital Standard Edition and Vault Edition qualify. You do not need to buy the more expensive Vault Edition simply to enter the beta on August 21.

The registration process depends on where you place the order.

Digital platform-store pre-orders

Digital orders made directly through the PlayStation Store, Microsoft Store, Steam or Battle.net are registered automatically.

You will not receive a separate Modern Warfare 4 beta code. Once early access begins, the beta should become available through the storefront connected to the purchase.

Before the test starts, confirm that the correct Activision account is linked to your platform profile. This is especially important for PC players who have previously used different Steam, Battle.net or Activision accounts.

Physical and third-party retailer pre-orders

Orders placed through participating retailers may include a 13-character early-access code. It is normally printed on the receipt or included in the retailer’s confirmation email.

Sign in to your Activision account, enter the code on the official beta redemption page and choose the platform on which you intend to play.

Activision will send the final platform token closer to the beta. A retailer code only covers the platform selected during registration; it does not unlock access on every linked system.

Does Game Pass include beta early access?

No. A Game Pass membership by itself does not replace an eligible pre-order or promotional code.

Activision has also confirmed that Modern Warfare 4 will not launch through Game Pass. Xbox players who want the first beta period must use a qualifying pre-order or another valid early-access offer.

How to join the Modern Warfare 4 open beta for free

The free Modern Warfare 4 open beta runs from August 28 through September 1.

No purchase or pre-order is required. Players can join on:

• PlayStation 5

• Xbox Series X|S

• Xbox on PC

• Steam

• Battle.net

• Nintendo Switch 2

An internet connection is required, and an online multiplayer subscription may be necessary on consoles. Availability may also differ by country, platform or retailer.

The free period is the better choice when you are undecided about buying the game. It gives you several days to test the movement, weapons, maps, matchmaking and performance without paying first.

Which platforms support the MW4 beta?

PlayStation 5

PS5 supports both testing periods.

A digital PlayStation Store pre-order provides automatic early access. Physical purchases may include a retailer code that must be redeemed through Activision.

Modern Warfare 4 is not planned for PS4, so previous-generation PlayStation players cannot enter either beta period.

Xbox Series X|S and Xbox on PC

Xbox Series X|S and Xbox on PC support early access and the free beta.

Microsoft Store purchases use Xbox Play Anywhere, allowing one qualifying digital purchase to provide access on current Xbox consoles and Xbox on PC. The game and beta are not available on Xbox One.

Steam and Battle.net

PC players can pre-purchase through either Steam or Battle.net for automatic early-access registration.

The official PC requirements and beta download size have not been published. Players should update the relevant launcher and check that their Activision account is correctly linked before August 21.

Nintendo Switch 2

Nintendo Switch 2 does not participate in the early-access period.

Its first playable window begins with the free beta on August 28. Activision says Switch 2 pre-orders will open on August 26, although no pre-order is needed to join the open test.

Can you preload the Modern Warfare 4 beta?

Activision has not announced a Modern Warfare 4 beta preload date or file size.

The official beta page currently states that further preload information will be shared later. Any date circulating without confirmation from Activision should be treated as a rumor.

Automatic digital registration does not mean the beta files are already available. It only confirms that the qualifying account has early-access permission.

Before the servers open:

• Update your console or PC launcher.

• Confirm the email address on your Activision account.

• Link the correct platform account.

• Redeem any retailer code.

• Leave enough storage space available.

• Check official Call of Duty channels for the preload announcement.

Players with slower internet connections should install the beta as soon as official preloading begins, since Call of Duty downloads can be substantial.

What content is included in the MW4 beta?

Activision has confirmed that the test will feature several multiplayer maps and modes.

Players will be able to unlock as many as 19 weapons and create loadouts using Tacticals, Lethals, Field Upgrades, Perks and Killstreaks. Match sizes will range from smaller 3v3 encounters to larger tactical battles involving tanks.

Confirmed modes and activities include:

• Search & Destroy

• Kill Block

• Training Mobility Course

• Small-scale 3v3 matches

• Large tactical battles

Kill Block is one of the more interesting additions. Its layout can change between rounds, which should force teams to adapt instead of relying on one memorized route.

The Training Mobility Course will provide an opportunity to learn the movement system before entering competitive matches. This could be especially useful if Modern Warfare 4 makes substantial changes to sprinting, sliding, mantling or general traversal.

The full map list, exact playlists, level cap and beta rewards have not yet been revealed.

What do Vault Edition owners receive during the beta?

Vault Edition customers can use Operators from the Hostile Alliance and Special Forces packs during the multiplayer beta.

They will also be able to test weapons and Blueprints from the Signature Weapon Collection. These bonuses do not provide extra beta days, exclusive maps or separate matchmaking.

The Standard Edition grants the same early-access dates when pre-ordered. Choose the Vault Edition for its additional cosmetic and launch content, not because you think it provides a longer beta.

Is beta early access worth pre-ordering for?

The answer depends on whether you already intend to buy Modern Warfare 4.

Early access ends on August 25, and the free beta begins three days later. That gap gives pre-order customers additional testing time, but it is not a long period of exclusivity.

A pre-order makes more sense when:

• You already plan to buy the full game.

• Your friends are entering early access.

• You want more time to learn the maps and weapons.

• You want to test several loadouts before the public weekend.

Waiting is safer when the beta will decide whether you buy the game. The open weekend still provides enough time to judge the core multiplayer without making an early commitment.

Remember that a beta is not the final build. Weapon balance, visibility, performance, matchmaking and playlists may change before launch. Progress may also be reset when the full game arrives.

Prepare for Modern Warfare 4 through TETHUB

Players who plan to pre-order through a platform store may need compatible wallet credit for their account region.

TETHUB offers digital gaming products and gift cards for several major platforms. Before ordering, check the account region, card currency, product type and redemption rules. A discounted code from the wrong region may not work on your account.

Xbox players can read the Xbox Gift Card guide and the article about the best Xbox region to buy games before choosing store credit. PC players using Battle.net can consider a compatible Blizzard Gift Card, while the guide on how to buy gift cards with USDT safely explains the required region and payment-network checks.

Final beta checklist

• Early access runs from August 21 to August 25.

• The free open beta runs from August 28 to September 1.

• PS5, Xbox Series X|S and PC support both periods.

• Nintendo Switch 2 joins only during the free beta.

• PS4 and Xbox One are not supported.

• Digital platform-store pre-orders need no code.

• Retailer purchases may include a 13-character code.

• Preload timing and download size remain unannounced.

• An active Activision account is needed for code redemption.

Use the Modern Warfare 4 beta as a real purchasing test. Look beyond the initial excitement and pay attention to gunplay, movement, map flow, visibility, matchmaking and technical performance. Those elements will tell you far more about the finished multiplayer than any pre-order cosmetic.
