Activision has locked in the beta schedule for Call of Duty: Modern Warfare 4, giving players a clear timeline for testing the upcoming shooter. This schedule matters because it defines exactly when you can jump into the game and what steps you need to take to get there before the full launch. Players who want early access must pre-order the title on supported platforms, while others can wait for the open beta window.
Activision confirms early access and open beta windows for the upcoming shooter
The game lands on PC via Steam, Xbox, and Battle.net, alongside Xbox Series X|S, PlayStation 5, and the Nintendo Switch 2. Activision confirmed these platforms in its recent update, ensuring broad availability across current and next-generation consoles. The Nintendo Switch 2 preorders open specifically on August 26, allowing those players to join the subsequent open beta.
The early access beta runs from August 21 to August 25 for those who pre-ordered on PC, Xbox Series X|S, and PlayStation 5. The open beta follows immediately after, running from August 28 to September 1 for all players regardless of purchase status. The full game release is scheduled for October 23, 2026, marking the end of the testing phase.
Activision describes the beta experience as featuring fluid movement and new modes like Search & Destroy and the brand-new Kill Block. The company also highlights a Training Mobility Course and the Gunny tool for building loadouts.
