Modern Warfare 4 joins Call of Duty: Warzone with Season 1, announced for November 6, 2026 at 00:00 ET / November 5 at 21:00 PT. Warzone is the free-to-play game; buying MW4 is a separate purchase for its Campaign, Multiplayer and DMZ. The October 23 MW4 release did not itself launch this later Warzone integration.
This page records the official October 28 Season 1 announcement, checked October 30. The announcement says a fuller Warzone briefing is coming November 2. That future briefing has not been used as a source here.
MW4 Warzone integration schedule
The announcement ties MW4 integration to Season 1 and gives the season's cross-platform start time. The conversions below refer to that same instant, using the time-zone rules on the release date.
| Time zone | Announced season start, converted where needed |
|---|---|
| US Pacific — PST | November 5, 2026, 21:00 |
| US Eastern — EST | November 6, 2026, 00:00 |
| UTC / UK — GMT | November 6, 2026, 05:00 |
| Central Europe — CET | November 6, 2026, 06:00 |
| China — Asia/Shanghai | November 6, 2026, 13:00 |
These are scheduled times, not proof that servers or every playlist are accessible at that moment. The US clocks have returned to standard time by November 6; reusing an October daylight-saving offset would shift the conversion by an hour.
Separate the free game from paid MW4 modes
| What you want to enter | Which release or product matters? |
|---|---|
| MW4 Campaign, Multiplayer or DMZ | The paid Modern Warfare 4 release, October 23 |
| MW4 content integrated into Warzone | Warzone's Season 1 update |
| Optional premium seasonal rewards | The relevant Battle Pass or BlackCell terms, separately from base access |
An MW4 store listing, a Warzone installation and a premium reward bundle answer different access questions. Do not buy the paid game solely because an installation screen mentions Warzone. Conversely, free Warzone access does not grant the paid MW4 Campaign, Multiplayer or DMZ.
For edition and upgrade contents, use the Standard and Vault price guide. For MW4's original access stages, use the game release schedule.
Announced integration content
The October 28 overview names Hajin and Zodiac as two new Warzone maps, alongside the return of Verdansk and Rebirth Island. It also announces connected MW4 content and seasonal progression. It does not provide every Warzone playlist, map rotation or installation requirement in that overview.
Open the official Season 1 roadmap at full size. The image separates Multiplayer, DMZ and shared content; open it when you want the full visual overview.
Read the labels on the roadmap before assuming an item belongs to Warzone. MW4 Multiplayer maps and DMZ's X01 location are not automatically Warzone destinations. Likewise, a mid-season item should not be treated as available at the season's opening.
Prepare without assuming unannounced requirements
- Check the installed product and account: distinguish Warzone from MW4's paid content packs.
- Keep the scheduled season time separate from a storefront's original MW4 release date.
- Check the official Warzone briefing when it is published, especially for playlists, required downloads and platform-specific instructions.
- If the expected option is absent after the scheduled update, check the current in-game message and official service information before buying another edition or repeatedly reinstalling.
This check does not establish the update's download size, prove account-specific reward transfers, or verify live server access. The current MW4 patch guide covers dated fixes; it is separate from this integration schedule.
