Modern Warfare 4 and Warzone Season 1 Arrives November 6

Season 1 for Call of Duty: Modern Warfare 4 and Call of Duty: Warzone launches November 6, 2026, per Activision's roadmap and Xbox Wire. The date marks full integration between the two: Modern Warfare 4's weapons and progression arrive in Warzone, with a shared Battle Pass so every match counts toward the same bar whether you're dropping into the big map or sprinting six-versus-six lanes.

It is also an ending. Warzone support for PS4 and Xbox One wraps up with Season 1, closing the last-gen chapter of the battle royale.

The details

• Season 1 start: November 6, 2026 for both MW4 and Warzone
• Integration: MW4 weapons, progression, and a unified Battle Pass in Warzone; BlackCell (via Vault Edition) begins with the season
• Last-gen: Warzone PS4 and Xbox One support ends with Season 1
• Already live: DMZ in early access since October 20; Shipment returned October 27, with Possession (October 29) and Infected (October 30) timed for Halloween

The warm-up is already underway

Activision has been drip-feeding content ahead of the season since the game's October 23 launch: the returning fan-favorite Shipment map landed October 27, and the Halloween-flavored Possession and Infected modes round out the week. DMZ's early-access run has been collecting balance patches — AI aggression and XP-rate fixes shipped in the launch window — with the mode's broader rollout continuing into the season.

Season 1 is always the real launch date for a modern Call of Duty: the October release is the opening act, and the first unified season starts the live-service flywheel that keeps weapon trees and battle pass tiers feeding each other for the rest of the year. The calendar officially starts November 6 — last-gen consoles just won't be on it.
