Call of Duty Modern Warfare 4 Beta Release Date and Schedule
The Call of Duty Modern Warfare 4 Beta release date is divided into two timed participation windows in 2026. The first weekend is Early Access for eligible pre-orders and pre-purchases. The second weekend is the Open Beta, which is available to all players on supported platforms without a pre-order requirement.
The official schedule lists all times in Pacific Time. Because the Beta is a limited-time event, players should plan around the exact start and end hours rather than assuming access will remain available throughout each calendar day.
| Beta phase | Start date and time | End date and time | Who can participate |
|---|---|---|---|
| Early Access | August 21, 2026, 11:00 AM PT | August 25, 2026, 10:00 AM PT | Eligible pre-order or pre-purchase players |
| Open Beta | August 28, 2026, 10:00 AM PT | September 1, 2026, 10:00 AM PT | All players on supported platforms |
| Early Access preload | August 20, 2026, 9:00 AM PT | Before Early Access begins | Players who meet Early Access requirements |
| Open Beta preload | August 26, 2026, 9:00 AM PT | Before Open Beta Weekend 2 | Players preparing for the open weekend |
The Early Access period is also described as Beta Weekend 1. Open Beta access is Beta Weekend 2, and it expands the available content while removing the pre-order requirement. Nintendo Switch 2 players are specifically scheduled to enter during Weekend 2, beginning August 28, 2026.
Convert the Pacific Time schedule to your local time before August 21. The Early Access and Open Beta windows end at 10:00 AM PT, not midnight.
The full game launch is scheduled for October 23, 2026, according to the official Beta information. Progression and rewards earned during the Beta are described as usable in the full game once it launches, subject to the terms of the event.
Preload Times and Access Windows
Preloading is the most reliable way to avoid losing play time when each Beta weekend opens. Eligible Early Access participants can begin downloading the first Beta build on August 20, 2026, at 9:00 AM PT. The broader Open Beta preload begins on August 26, 2026, at 9:00 AM PT across supported platforms.
| Action | Date | Time | Recommended preparation |
|---|---|---|---|
| Early Access preload | August 20, 2026 | 9:00 AM PT | Verify eligibility and available storage |
| Early Access launch | August 21, 2026 | 11:00 AM PT | Start the Beta and sign in to the required account |
| Open Beta preload | August 26, 2026 | 9:00 AM PT | Install the Weekend 2 build or update |
| Open Beta launch | August 28, 2026 | 10:00 AM PT | Join without a pre-order requirement |
| Open Beta close | September 1, 2026 | 10:00 AM PT | Complete final matches and reward goals |
The Early Access preload date comes before the first participation window, giving eligible players time to install the client. Players who wait until the launch hour may face download queues, patches, or account verification delays.
Confirm Your Participation Window
Decide whether you qualify for Early Access through a participating digital or retail pre-order. If you do not, plan for Open Beta Weekend 2 beginning August 28, 2026.
Prepare the Correct Platform
Confirm the platform selected during registration. Retail codes are issued for the console chosen during the redemption process, so selecting the wrong platform can create access problems.
Preload the Beta
Download Early Access beginning August 20 at 9:00 AM PT, or download the Open Beta build beginning August 26 at 9:00 AM PT.
Sign In Before Launch
Use the Activision account connected to your Beta registration. Digital pre-orders are automatically validated on the listed storefronts, while participating retail purchases may require code redemption.
Beta access is limited-time and may vary by territory or retailer. Check your local schedule and retailer instructions before relying on a code or launch window.
A stable internet connection is required. The official notice also states that an online multiplayer subscription may be required for multiplayer access, depending on the platform and account conditions.
Platforms and Beta Content
The 2026 Beta supports a broad group of platforms. Early Access codes are listed for Xbox Series X|S, PlayStation 5, PC Battle.net, Xbox on PC, and PC Steam. Weekend 2 expands access to all supported platforms, including Nintendo Switch 2.
| Platform or access route | Early Access availability | Open Beta availability | Entry notes |
|---|---|---|---|
| Xbox Series X | S | Listed | Listed |
| PlayStation 5 | Listed | Listed | Digital pre-orders are automatically validated |
| PC Battle.net | Listed | Listed | Digital pre-purchase registers access |
| Xbox on PC | Listed | Listed | Requires the applicable Xbox PC route |
| PC Steam | Listed | Listed | Digital pre-purchase registers access |
| Nintendo Switch 2 | Not listed for Weekend 1 | Listed for Weekend 2 | No pre-order required for August 28 access |
The Beta focuses on multiplayer gameplay across multiple maps and modes. The listed content includes core 6v6 maps and modes, Kill Block, and the single-player Campaign mission “Entrenched.”
Weekend 2 adds Ground War: Combat Outpost and the new Zodiac Resurgence map in Call of Duty: Warzone. These additions make the second weekend especially important for players who want to sample the widest announced Beta content.
Core 6v6
Traditional team-based multiplayer maps and modes designed for smaller-scale engagements.
Kill Block
A listed Beta mode that adds another multiplayer format to the Weekend 1 and Weekend 2 rotation.
Entrenched
The available single-player Campaign mission included in the Modern Warfare 4 Beta.
Weekend 2 Additions
Ground War: Combat Outpost and Zodiac Resurgence expand the Beta offering on August 28.
Weekend 1 is useful for getting an early look at core multiplayer and the Campaign mission. Weekend 2 is the key window for the largest announced content lineup.
The official Beta page notes that platform availability and launch dates may change. Treat the published schedule as the current 2026 plan, but recheck the official Call of Duty Modern Warfare 4 Beta page before each preload or launch window.
How to Get Early Access
Early Access depends on the purchase route. Digital pre-orders and pre-purchases through the Microsoft Store, PlayStation Store, Battle.net, and Steam Store are automatically validated for Early Access on the applicable platform. In these cases, a separate code is not required.
Participating retail purchases work differently. A qualifying retail order provides a 13-character Early Access Beta code, usually printed on the receipt or sent through an online receipt email. The code can be redeemed at the official Beta redemption page.
| Purchase method | Code required? | Main action | Account requirement |
|---|---|---|---|
| Microsoft Store digital pre-order | No | Preload when available | Activision account connection |
| PlayStation Store digital pre-order | No | Preload when available | Activision account connection |
| Battle.net digital pre-purchase | No | Preload when available | Activision account connection |
| Steam digital pre-purchase | No | Preload when available | Activision account connection |
| Participating retail order | Usually yes | Redeem the 13-character code | Activision account required |
Early Access Preparation:
- Confirm the selected platform before redeeming a retail code
- Create or verify an Activision account
- Redeem a qualifying retail code at the official Beta redemption page
- Check the account email for the Early Access token
- Begin preload on August 20, 2026, at 9:00 AM PT
After entering a retail code, players must log in with an Activision account. Registered players receive an Early Access token by email before the Beta begins. The official information states that tokens are expected shortly after the Beta preload starts on August 20, 2026, at 9:00 AM PT, and may also appear through the redemption page.
If a retail code is missing, unreadable, or never arrived, the correct solution is to contact the retailer. Avoid using a code intended for another platform, because the token is tied to the console selected during registration.
Digital pre-orders and pre-purchases are the simplest Early Access route because the official storefront validates participation automatically without a separate redemption code.
Players who do not pre-order can still join the Open Beta during Weekend 2. This is particularly relevant for Nintendo Switch 2 players, whose announced Beta access begins August 28, 2026, without a pre-order requirement.
Rewards, Requirements, and FAQ
The Beta includes in-game rewards for participation. Rewards become available for use in the Beta after they are unlocked and are described as playable in Modern Warfare 4 after the full game launches on October 23, 2026.
