Modern Warfare 4 beta dates confirmed, Switch 2 included
First CoD beta for Switch 2, dates set but not revealed

Activision confirmed beta dates for Modern Warfare 4 today, with both closed and open beta windows planned across PC, PlayStation, Xbox, and Switch 2. The announcement came via Eurogamer, marking the first time a mainline Call of Duty beta will run on Nintendo's upcoming hardware.
The closed beta kicks off first, followed by an open beta window later in the cycle. Exact dates weren't detailed in the initial announcement, but Activision confirmed the return of Call of Duty: Next, the annual multiplayer showcase event that's become the standard reveal format for new CoD titles since 2022. Expect gameplay footage, map breakdowns, and weapon balancing details at Next before the beta drops.
Switch 2 inclusion is the real story here. If the handheld can hold 60fps in matchmaking — a tall order given portable thermal constraints — it opens up CoD to an entirely new audience. If it struggles, expect performance discussions to dominate beta coverage.
