How to Play Modern Warfare 4 Open Beta: Dates and Platforms

Activision, Infinity Ward, and Beenox confirmed Call of Duty: Modern Warfare 4's open beta will span two August weekends: early access August 21–25 for pre-orders, followed by a public open beta August 28–September 1.
Players can test various multiplayer modes, including the new Kill Block experience and 3v3 skirmishes, while unlocking as many as 19 different weapons across small-scale tactical battles and large-scale engagements featuring tanks.
Vault Edition pre-orders unlock exclusive Hostile Alliance Operator Pack characters and Signature Weapon Blueprints; Modern Warfare 4 skips Xbox Game Pass at launch, meaning all players must purchase or pre-order to access the beta.
The Call of Duty: NEXT broadcast on August 21 will precede the early access beta, featuring live gameplay and developer commentary as the primary multiplayer showcase before public testing begins.
Marking the franchise's return to Nintendo platforms, Modern Warfare 4 launches October 23 on PC, PS5, Xbox Series, and Nintendo Switch 2, with Switch 2 pre-orders opening August 26.
