MW4 Season 1 starts November 6: Hajin comes to Warzone, and what's next for DMZ

Season 1 is two weeks away from launch. Modern Warfare 4 Season 1 starts on Friday, November 6, 2026, and it is the first big update after DMZ goes live.

The launch calendar

Date	What happens
October 16	Campaign early access (digital pre-orders)
October 19, by 9 AM PT	Required update for DMZ early access
October 20, 10 AM PT	DMZ early access (digital pre-orders)
October 23	Full launch, midnight local time
October 27	Shipment returns to Multiplayer
November 6	Season 1

The Season 1 date comes from the official roadmap Call of Duty shared on October 14. Full Season 1 patch notes and content haven’t been posted yet.

Hajin becomes a Warzone map

With Season 1, Hajin is also a Warzone Battle Royale map. So the zone you learn in DMZ is the same ground Warzone players will drop into.

What this means for DMZ players:

• Your map knowledge counts twice. The 13 major areas, roads and rooftops you learn in DMZ carry over to Warzone.
• DMZ stays its own mode. DMZ keeps its own damage and movement tuning, FOB, progression and exfil rules.
• Not known yet: how much the Warzone version of Hajin changes the layout or closes off areas compared with DMZ.

Your weapon levels and attachment unlocks are shared between DMZ, Multiplayer and Warzone (cross-mode weapon progression), so leveling a gun in DMZ helps you in Warzone too.

What’s next for DMZ

Infinity Ward has named three things coming after launch:

1. XL1. In the From The Ward episode on October 5, the developers named XL1 as a new DMZ location for Season 1 and compared it to Building 21 from the 2022 DMZ.
2. X01. In a Reddit AMA on October 9, the team called its first post-launch DMZ map X01. It isn’t clear yet whether X01 and XL1 are the same place under two names.
3. A bigger Hajin. Hajin will grow toward the Russian border once the northern area opens, in a later season.

The developers also say more bosses, maps and events will follow after launch. We will add them to the database as soon as they are confirmed.

Get ready before Season 1

You have about two weeks of DMZ before Season 1. Good ways to use them:

• Level your DMZ Player Level toward 70 and open the FOB stations. See the FOB page.
• Work through DMZ Orders, which unlock the Boss Board.
• Unlock weapons by exfiling with their Weapon Manuals (weapons guide).
• Save DMZ Cash for Operator Prestige, which starts at 200,000.
