Call of Duty Modern Warfare 4 Beta sign up Requirements
Call of Duty Modern Warfare 4 Beta sign up depends on how you purchase the game and which Beta window you want to enter. The official Open Beta supports Early Access for qualifying pre-orders, while the second weekend is available to all players on supported platforms without a pre-order.
For Early Access, you can pre-order or pre-purchase Call of Duty: Modern Warfare 4 through a participating retailer or a supported digital storefront. Retailer purchases generally provide a 13-character Beta code. Digital purchases through the Microsoft Store, PlayStation Store, Battle.net, or Steam Store automatically validate your eligibility.
| Access route | Pre-order required | Code required | Registration method |
|---|---|---|---|
| Microsoft Store | Yes for Early Access | No | Automatic validation |
| PlayStation Store | Yes for Early Access | No | Automatic validation |
| Battle.net | Yes for Early Access | No | Automatic validation |
| Steam Store | Yes for Early Access | No | Automatic validation |
| Participating retailer | Yes for Early Access | Yes | Redeem code at Activision |
| Open Beta Weekend 2 | No | No | Join during the open window |
A retailer receipt or online order confirmation should include the Early Access code. If the code is missing, unreadable, or lost, contact the retailer before the Beta begins.
Digital Storefront
Digital pre-orders on supported stores are automatically validated for Early Access.
Retailer Purchase
Participating retailers provide a 13-character code for Beta registration.
Activision Account
An Activision account is required to redeem an Early Access code.
Open Weekend
Weekend 2 is open to all players on supported platforms without a pre-order.
The official Call of Duty: Modern Warfare 4 Beta page is the best place to verify current eligibility, platform availability, and participation details.
Step-by-Step Beta Registration
Use the following process when you receive an Early Access code from a participating retailer. Digital pre-orders do not normally require manual code redemption, but you still need the correct Activision account and platform connection for access.
Choose a Supported Platform
Select Xbox Series X|S, PlayStation 5, PC Battle.net, Xbox on PC, or PC Steam when purchasing for Early Access. The Beta code is tied to the console or platform selected during registration.
Create or Sign In to Activision
Visit the official Beta redemption page and sign in with your Activision account. If you do not have an account, create one and complete email verification before entering the code.
Redeem the Retailer Code
Enter the 13-character Early Access Beta code at callofduty.com/betaredeem. Follow the instructions carefully and confirm the platform selection before submitting.
Watch for the Beta Token
Registered players receive an Early Access Beta token by email shortly after the preload period starts. Tokens are also expected to appear on the official redemption page.
Preload and Join
Preload Early Access begins August 20, 2026, at 9:00 AM PT. Once the Early Access window opens, download the Beta and sign in using the same account connected to registration.
| Registration stage | What to prepare | Expected result |
|---|---|---|
| Account setup | Activision account and verified email | Account can receive Beta notices |
| Code redemption | 13-character retailer code | Early Access registration completed |
| Platform selection | Correct console or PC platform | Token is issued for the selected platform |
| Preload | Storage space and internet connection | Beta client is ready before launch |
| Beta login | Linked Activision account | Access during the eligible window |
Select the platform you actually plan to use. The official registration guidance states that a code is issued only for the console or platform chosen during registration.
If you pre-ordered digitally through a supported storefront, do not look for a separate code unless the store specifically provides one. Digital purchases are automatically validated for Early Access, and the Beta can be downloaded when access becomes available.

Beta Content and Reward Progression
The Modern Warfare 4 Beta focuses on Multiplayer content across core 6v6 maps and modes, with Kill Block also listed among the available experiences. The Beta additionally includes the single-player Campaign mission “Entrenched.” Weekend 2 introduces Ground War: Combat Outpost and the Zodiac Resurgence map in Call of Duty: Warzone.
Playing the Beta unlocks cosmetic rewards during the test period. These items become available in the Beta after unlocking and are planned to remain usable in Modern Warfare 4 after the full game launches.
| Player level | Reward |
|---|---|
| Level 4 | Three Paces legendary emblem |
| Level 8 | First Reserve weapon charm |
| Level 12 | Mion’giao legendary weapon sticker |
| Level 16 | Last Charge legendary calling card |
| Level 20 | Dread Tiger operator skin for Reyes |
| Level 23 | Field Tested epic spray |
| Level 26 | Beta Rights epic loading screen |
| Level 30 | Beta Forge ISO 9 Shadow weapon blueprint |
The first Beta weekend reaches level 20, while the second weekend raises the maximum progression level to 30. This makes Weekend 2 especially important for players pursuing the Reyes operator skin, loading screen, and ISO 9 Shadow blueprint.
Additional cosmetic rewards may be connected to Twitch viewing, challenges, and combat record progression. The listed Twitch reward requirements include viewing milestones of 30, 45, and 50 minutes, but individual reward assignments should be checked through the official campaign information when available.
| Reward activity | Requirement | Reward status |
|---|---|---|
| Beta leveling | Reach levels 4 through 30 | Listed rewards available by milestone |
| Twitch Drops | Watch designated streams for 30–50 minutes | Cosmetic rewards listed for viewing milestones |
| Classified challenge | Complete the stated challenge | Reward details classified |
| Combat record | Progress through combat record objectives | Blueprint, emblem, and charm details classified |
| Default items | Enter the Beta and review available content | Three default items listed |
If you want the broadest listed reward set, continue progressing into Weekend 2 and aim for level 30. The final listed milestone includes the Beta Forge ISO 9 Shadow weapon blueprint.
Beta rewards are limited-time unlocks. Plan your play sessions around the active windows because the provided official information states that Beta rewards will not remain earnable after the Beta concludes.
