Modern Warfare 4 Season 1 starts on Friday, November 6, 2026, two weeks after the game’s October 23 launch. Infinity Ward confirmed the date in its official roadmap on October 14. It is also the day Warzone switches over to Modern Warfare 4, and the day Warzone stops working on PS4 and Xbox One. Here is everything that changes.
Modern Warfare 4 roadmap to Season 1
| Date | What happens |
|---|---|
| October 16 | Campaign early access for digital pre-orders |
| October 20 | DMZ early access |
| October 23 | Full launch: campaign, multiplayer and DMZ |
| October 27 | Remastered Shipment map reported to arrive in multiplayer |
| November 6 | Season 1 starts in Modern Warfare 4 and Warzone |
What Season 1 brings to Modern Warfare 4
- The first Battle Pass and BlackCell. If you bought the Vault Edition, its included Battle Pass, COD Points and tier skips become usable when Season 1 starts.
- New seasonal weapons, according to roadmap coverage.
- Infinity Ward has not yet published full Season 1 patch notes, map lists or Battle Pass rewards. Activision usually reveals them in the week before a season.
Warzone integration: what changes
- From November 6, Warzone uses Modern Warfare 4 weapons, operators and seasonal progression as one connected experience. Until then it keeps its Black Ops 7 setup.
- Two new maps are reported for the integration: Hajin for Battle Royale and Zodiac for Resurgence. Treat these as reported until Activision’s Season 1 blog confirms them.
- Operators and weapons you own from Modern Warfare II, Modern Warfare III, Black Ops 6 and Black Ops 7 stay usable, including bought skins and blueprints.
- Warzone stays free-to-play. You do not need to buy Modern Warfare 4 to play it.
- Warzone is also reported to arrive on Nintendo Switch 2 on the same date.
Warzone ends on PS4 and Xbox One
Season 1 makes Warzone unplayable on PS4 and Xbox One. New downloads and in-game stores on those consoles were already closed earlier in 2026. If you still play on last-gen hardware, your account and owned items carry over to PS5, Xbox Series X|S or PC when you sign in with the same Activision account.
Should you wait for Season 1 to buy?
If you mainly play multiplayer or Warzone, buying around November 6 means you start with the first Battle Pass and a game with two weeks of fixes. If you want the campaign, there is no reason to wait. Our Modern Warfare 4 review roundup explains why critics rate it the best Call of Duty in years.
