MP1st is distributing free Modern Warfare 4 beta codes to players ahead of the early access and open beta weekends, with access spanning multiple platforms and including both campaign and multiplayer content
MP1st has announced a new community giveaway offering free beta codes for Call of Duty: Modern Warfare 4, ahead of the game's upcoming early access and open beta periods. The initiative is designed to encourage genuine player engagement and limit automated code collection, with codes distributed to readers who participate in the site's comment section. No purchase is required, and the codes are valid across all supported platforms.
Beta Access and Schedule
The Modern Warfare 4 beta is structured across two weekends. Early access begins on Friday, 21 August, immediately following the Call of Duty: NEXT event, and runs until 25 August. This initial phase is available to players on Xbox Series X|S, PlayStation 5, and PC who have digitally pre-ordered the game. The open beta follows from 28 August to 1 September, expanding access to all players, including those on Nintendo Switch 2.
To participate in the giveaway, readers are asked to leave a comment on MP1st, sharing feedback or suggestions for the site. Winners will receive their beta codes via the email linked to their commenting account. Codes can be redeemed for any platform, with platform-specific download instructions provided closer to the beta start date.
Beta Content and Features
This beta marks the first time Modern Warfare 4 will allow players to experience both multiplayer and a segment of the campaign ahead of launch. The early access beta introduces five new 6v6 multiplayer maps-Rooftops, Silkworm, Transit 213, Cachette, and Lotus-alongside the new Kill Block map and mode. The campaign mission 'Entrenched' will also be available for preview.
Multiplayer modes confirmed for the beta include Team Deathmatch, Domination, Hardpoint, Kill Confirmed, Inflation, Search & Destroy, and the new Kill Block mode, which supports both 10v10 and 3v3 Gunfight variants. The open beta will add the Zodiac Warzone Resurgence map, additional Ground War maps, and the Lithium multiplayer map, broadening the available content for all participants.
Platforms and Redemption Process
Beta codes distributed through the MP1st giveaway are compatible with Xbox Series X|S, PlayStation 5, PC (via Steam and Battle.net), and Nintendo Switch 2. To redeem a code, players must visit the official Call of Duty beta redemption site, log in or create an Activision account, and enter their code along with their platform and region. Successful registration will be confirmed on the site, with platform-specific download codes sent out closer to the beta's start.
Players should note that the initial code does not grant immediate access to the beta client; a second, platform-specific code will be required for download, which will be delivered by email ahead of the relevant beta weekend. MP1st has stated that winners will be selected before the beta period begins, ensuring timely access for those chosen.
What Remains Unconfirmed
While the beta content and schedule have been outlined, some details remain subject to change. The final list of available maps and modes may be adjusted prior to launch, and technical performance across platforms has not yet been independently verified. It is also unclear whether progress made during the beta will carry over to the full release. Players are advised to monitor official channels for any updates or changes to the beta structure or content.
Understanding how beta access works is essential for players interested in early hands-on time with upcoming releases. A beta is typically a pre-release version of a game made available to a limited audience for testing and feedback. Access may be restricted by platform, pre-order status, or community engagement, and content is often limited compared to the final release. Progress and unlocks earned during a beta are not always retained, and technical performance may differ from the launch build as developers continue to optimise the game based on player input and internal testing.
