Discord Nitro subscribers can access the Call of Duty: Modern Warfare 4 beta early by claiming a free code through the Nitro rewards tab. This early access period runs from August 21 to August 25, 2026, and is available on Xbox Series X/S, PlayStation 5, and PC via Battle.net, Steam, and Xbox on PC.
How to Claim Your Beta Code
Follow these steps to secure your access:
- Open the Discord desktop app and ensure you are logged into an account with an active, full Discord Nitro subscription.
- Navigate to User Settings and select the Nitro tab.
- Locate the Modern Warfare 4 beta promotion within the available rewards and click Take me there.
- Copy your unique code once it appears.
- Visit the official Call of Duty beta redemption page.
- Sign in to your Activision account, enter your code, and select your preferred platform and region.
- Submit the form and look for the confirmation message to complete the process.
Important Access Details
The code is limited to one per account, and you must select your platform carefully during the redemption process. If you choose PlayStation 5, for example, the token will not function on PC, and codes cannot be swapped after submission.
If you miss the early access window, an open beta will be available to all players starting August 28, 2026, and running through September 1, 2026. No codes are required for the open beta period.
