Call of Duty Modern Warfare 4 Open Beta Starts August 28

The first major public playtest for the upcoming video game Call of Duty: Modern Warfare 4 will begin next month, publisher Activision has confirmed. An early access beta for players who pre-order the game will run from August 21 to August 25 on PlayStation 5, Xbox Series X/S, and Windows PC. This will be followed by a free open beta from August 28 to September 1, which will also include players on the Nintendo Switch 2 for the first time in the series.

The beta is a critical feedback window for developer Infinity Ward ahead of the game's full release on October 23, 2026. It will offer a substantial preview of the multiplayer experience, featuring 19 unlockable weapons, a selection of new Operators, and several game modes. These include the returning fan-favorite Search & Destroy, a Training Mobility Course, and a new mode called Kill Block. Described as a modular 10-versus-10 battleground, Kill Block dynamically reconfigures its layout each match using pre-made parts, creating over 500 possible map configurations. Progress and rewards earned during the beta will carry over to the full game.
