- Call of Duty Modern Warfare 4 Beta preload begins August 20 for eligible Early Access players.
- Open Beta preload begins August 26 for all players across supported platforms.
- Separate installation is required because the Beta is not bundled with the regular Call of Duty install.
- PC preparation includes an SSD, broadband internet, TPM 2.0, Secure Boot, and compatible drivers.
- One download covers both weekends when you participate in Early Access and the Open Beta.
Call of Duty Modern Warfare 4 Beta preload Dates and Access
Call of Duty Modern Warfare 4 Beta preload access is split between Early Access and the Open Beta. Early Access is reserved for eligible players, while the second weekend is available to everyone on supported platforms. All listed times use Pacific Time and apply to the 2026 Beta schedule.
The Beta is a separate installation from the main Call of Duty experience. You must locate it through your platform storefront or launcher and start the download manually. A normal Call of Duty update will not automatically install the Beta.
| Beta Period | Preload Begins | Play Begins | Scheduled End | Eligibility |
|---|---|---|---|---|
| Early Access, Weekend One | August 20, 2026 at 9:00 AM PT | August 21 at 11:00 AM PT | August 25 at 10:00 AM PT | Pre-order, pre-purchase, or valid Beta Code |
| Open Beta, Weekend Two | August 26, 2026 at 9:00 AM PT | August 28 at 10:00 AM PT | September 1 at 10:00 AM PT | All players |
| Nintendo Switch 2 Weekend Two | August 26, 2026 at 9:00 AM PT | August 28 at 10:00 AM PT | September 1 at 10:00 AM PT | All players |
Early Access
Download from August 20 if your account qualifies through a pre-order, pre-purchase, or redeemed Beta Code.
Open Beta
All players can begin downloading on August 26 without a pre-order or code.
Separate Install
Search for the dedicated Beta listing instead of waiting for the main Call of Duty client to update.
Progress Carryover
Weekend One and Weekend Two use the same Beta installation, so a second download is not required.
Start the preload as soon as your access window opens. Storefront availability can vary by region, and downloading early leaves time for updates or troubleshooting.
For the latest timing notices and launch conditions, check the official Call of Duty Beta information before the weekend begins.
How to Download and Launch the Beta
The fastest approach is to use the storefront or launcher associated with your platform. Install the Beta separately, then launch it only after the scheduled play window begins. Signing in with an Activision Account helps connect eligible rewards to your future game profile.
Confirm Your Access Window
Check whether you are joining Early Access or the Open Beta. Early Access requires a qualifying pre-order, pre-purchase, or Beta Code, while Weekend Two is open to all players.
Search for the Dedicated Beta Listing
Open your platform’s digital storefront or PC launcher and search for “Call of Duty: Modern Warfare 4 Beta.” Do not rely on an automatic download from the main Call of Duty installation.
Install the Beta
Select the Beta listing and choose Install or Download. Allow the full preload to finish before launch time, then apply any additional update shown by the platform.
Sign In with Activision
Launch the Beta with the Activision Account you want to use for progression and rewards. This keeps eligible cosmetic rewards connected to your account.
Launch During the Live Window
Open the installed Beta after the scheduled start time. If the game does not appear immediately, refresh the storefront, check for updates, and restart the launcher or console.
| Platform | Download Path | Launch Path | Early Access |
|---|---|---|---|
| Xbox Series X|S | Microsoft Store, search for the Beta | My Games & Apps, then select the Beta | Available |
| Xbox on PC | Xbox app, open Store and search | Xbox app library | Available |
| PlayStation 5 | PlayStation Store, search for the Beta | Home screen or Game Library | Available |
| Steam | Steam Store page for Modern Warfare 4 | Steam Library | Available |
| Battle.net | Call of Duty page, select MW4 Beta in Game Version | Call of Duty page, then Play | Available |
| Nintendo Switch 2 | Nintendo eShop for Weekend Two | HOME Menu | Weekend Two only |
Players joining both Beta weekends only need to download the Beta once. Content and progression from Weekend One carry into Weekend Two during the test period.
On Xbox for PC, an initial portion of the Beta may download before the larger download becomes available. If the install appears incomplete, check the listed release time rather than repeatedly restarting the application.
PC Requirements and Performance Setup
PC players should prepare more than storage space before the preload. The Beta requires an SSD, broadband internet, and a DirectX 12-compatible system. Shader Preloading is also designed to prepare graphics data before play, which can reduce shader-related stutters during matches.
| Component | Minimum Specification | Recommended Specification |
|---|---|---|
| Operating System | Windows 10 64-bit, latest update | Windows 11 64-bit, latest update |
| Processor | AMD Ryzen 5 1600 or Intel Core i5-8400 | AMD Ryzen 5 3600 or Intel Core i7-8700 |
| Memory | 12 GB RAM | 16 GB RAM |
| AMD Graphics | Radeon RX 470 | Radeon RX 6700 XT |
| NVIDIA Graphics | GeForce GTX 970 or GTX 1060 | GeForce RTX 3060 Ti |
| Intel Graphics | Arc A580 | Arc B580 |
| Video Memory | 3 GB | 8 GB |
| Storage | SSD required | SSD required |
| DirectX | DirectX 12 compatible | DirectX 12 compatible |
| Network | Broadband internet | Broadband internet |
| Driver Brand | Listed Beta Driver |
|---|---|
| NVIDIA | 610.47 |
| AMD | 26.7.1 |
| Intel | 32.0.101.8861 |
Shader Preloading prepares rendering data for your specific graphics card and driver combination. On Battle.net, it is enabled from the first Beta installation. On Steam, the first boot still requires a one-time shader compile, after which Shader Preloading supports later updates.
The process may use some system resources while it runs in the background. You can continue using the PC, disable the feature in settings, or interrupt it and allow it to resume later. Waiting for shader preparation before entering a match is generally preferable to troubleshooting visual stutter during play.
TPM 2.0 and Secure Boot must be enabled for online Beta play on PC. If either feature is disabled, resolve the Windows security setting before launch.
Use the following preparation order:
- Update Windows before the preload begins.
- Confirm the Beta is installed on an SSD.
- Install the listed graphics driver for your GPU brand.
- Enable TPM 2.0 and Secure Boot in your system firmware if required.
- Close large downloads and background applications during shader preparation.
- Leave enough free SSD space for updates beyond the initial installation.
The published specifications apply to the 2026 Beta and may differ from the requirements for the full game at launch.
Troubleshooting Preload and Launch Problems
Most preload problems come from one of four causes: the Beta is not live for your platform, the account lacks Early Access eligibility, the storefront has not refreshed, or the installation still needs an update. Work through the checks below before reinstalling.
| Problem | Likely Cause | Recommended Fix |
|---|---|---|
| Beta does not appear | Wrong access window or storefront cache | Confirm the date, time, region, and eligibility, then restart the storefront |
| Download is only partial | Platform has released an initial package | Check the scheduled bulk-download time and keep the listing installed |
| Beta will not launch | Live window has not started or an update is pending | Check for updates, restart the platform, and relaunch after the start time |
| PC blocks online play | TPM 2.0 or Secure Boot is disabled | Enable both Windows security features in firmware settings |
| Stuttering on first launch | Shaders are still compiling | Allow Shader Preloading or the first-run shader compile to finish |
| Update Requires Restart appears | A data patch arrived while the game was open | Restart the Beta so the patch can apply correctly |
Preload Readiness Checklist:
- Confirm the correct 2026 Beta weekend and access requirement
- Search for and install the separate Modern Warfare 4 Beta listing
- Sign in with the intended Activision Account
- Verify SSD storage, broadband internet, and current PC drivers
- Enable TPM 2.0 and Secure Boot before online PC play
Modern Warfare 4 reduces the number of updates that require a restart, but a restart may still be necessary when a patch arrives while the Beta is running.
On PlayStation 5, data patches generally do not require a restart unless the game is running or suspended when the patch is released. On Xbox Series X|S and Nintendo Switch 2, Beta patches may continue to require a restart. PC data patches usually apply without a restart unless the game is open during deployment.
If the Beta is missing, verify these items in order:
- The Beta is currently available for your platform.
- Your account meets the Early Access requirement, if applicable.
- The storefront or launcher is using the correct account.
- The dedicated Beta listing has been installed.
- The platform has been restarted after the listing or update appeared.
Beta Rewards, Progression, and Account Preparation
Beta rewards are tied to the Activision Account used during the test. Cosmetic rewards earned in the Beta are scheduled to become available when Modern Warfare 4 launches on October 23, 2026. Beta rank, weapon unlocks, and other in-Beta progression do not continue after the Beta ends.
| Reward Unlock Level | Reward | Weekend Availability |
|---|---|---|
| Level 4 | “Through the Paces” Legendary Emblem | Weekend One and Two |
| Level 8 | “First Served” Weapon Charm | Weekend One and Two |
| Level 12 | “Meonjeo” Legendary Weapon Sticker | Weekend One and Two |
| Level 16 | “Last Charge” Legendary Calling Card | Weekend One and Two |
| Level 20 | “Dread Tiger” Operator Skin for Reece | Weekend One |
| Level 23 | “Field Tested” Epic Spray | Weekend Two |
| Level 26 | “Beta Rights” Epic Loading Screen | Weekend Two |
| Level 30 | “Beta Forged” ISO Nightshade Weapon Blueprint | Weekend Two |
Weekend One has a maximum player level of 20, making the first five listed level rewards available. Weekend Two raises the maximum to level 30, allowing players to reach all eight milestone rewards.
Additional cosmetic rewards may come from default items, classified challenges, and Combat Record activities. Their availability and exact unlock conditions should be checked in the live Beta menus rather than assumed from the level track.
Account Rewards
Use the correct Activision Account so eligible cosmetic items can be connected to the full game profile.
Weekend One Goal
Reach Level 20 to pursue the first five milestone rewards, including the Reece Operator Skin.
Weekend Two Goal
Reach Level 30 to unlock the complete listed milestone track, including the ISO Nightshade Blueprint.
Prioritize regular play and the available Beta challenges. Do not expect Beta rank, weapon unlocks, or temporary progression to carry into the full release.
Twitch Drops are also planned for Call of Duty: NEXT and participating Modern Warfare 4 Beta streams. Link your Activision and Twitch accounts before watching eligible broadcasts. Listed viewing milestones include cosmetic Emblems, Calling Cards, and Charms earned at 15, 30, and 45 minutes.
