The upcoming Call of Duty: Modern Warfare 4 beta is introducing a major shift for the franchise by including content outside of traditional multiplayer testing.
For the first time in Call of Duty history, players participating in the beta will get access to a campaign mission alongside Warzone content. Details regarding the specific campaign mission or the exact scope of the Warzone additions remain tied to the initial announcement, but the inclusion breaks from the traditional multiplayer-only structure seen in past series betas.
Additional release windows, platform availability dates, and participation requirements for the Call of Duty: Modern Warfare 4 beta have not yet been detailed beyond the initial feature confirmation.
