When Does Warzone Switch to Modern Warfare 4?

Modern Warfare 4 launched on 23 October 2026. Warzone did not change that day, and a lot of people expected it to.

Why nothing changed at launch

Warzone's integration with a new Call of Duty has run on a separate schedule for several years now. Modern Warfare 4 shipped with Multiplayer, the campaign and DMZ. Warzone stayed on its Black Ops 7 integration.

The reported date

Season 1 is widely reported for 6 November 2026, for both Modern Warfare 4 and Warzone. No start time has been published, and Activision has not posted a single global timestamp across its regional pages.

Treat the date as reported rather than confirmed-by-the-hour, and expect the usual regional timing differences.

What the integration is expected to bring

Reporting points to Modern Warfare 4's weapons, Operators and movement mechanics coming into Warzone, headlined by the Hajin battle royale map, which served as the DMZ setting, and a Zodiac Resurgence island.

Whether Verdansk features is where sources disagree. We would not plan around it.

Also reported for 6 November: the end of Warzone support on PlayStation 4 and Xbox One.

What is not announced

Season 1's exact start time, the new Multiplayer maps and modes coming with it, and the Battle Pass contents.

What to do before then

If you want Modern Warfare 4 weapons ready for Warzone on day one, level them now. Weapon level is not mode-locked the way camo challenges are, so the work carries. Weapon leveling covers it, and the Warzone camos are worth reading before you plan a grind around them.
