2026/11/07

We're rolling out another round of fixes and improvements across Multiplayer and DMZ.

Thank you for your continued feedback as we work to improve MW4’s experience.

Here's what's included in today's update.

GLOBAL

Stability

  • Fixed several stability issues for a better experience across all modes.
  • Updated the Operator Selection menu to improve the display and organization of Operator Variants.

MULTIPLAYER

Maps

  • Fixed an issue on Lithium where Field Upgrade equipment could be lost when deployed on certain surfaces.

Modes

  • Fixed an issue where objectives in Grind would not spawn correctly in Private Match.

Killstreaks

  • Fixed an issue where players could be removed from the Gunship Killstreak when their Operator was eliminated.

UI/UX

  • Updated Map Voting widget to support playlists with three map and mode combinations, such as Shransit.
  • Fixed an issue where Grinding for Royalty Warzone event Achievements could appear outside of Battle Royale.
  • Fixed an issue where Battle Pass progress on an individual tier would not roll over to the next tier if the player used a Token.
  • Fixed an issue where players could get stuck on the Scoreboard at the end of a Hardcore match.

DMZ

  • Addressed several issues to improve overall gameplay stability in X01.

Gameplay

  • Fixed an issue where destroying a boat before completing the second-to-last objective in the Operation Fallen Ember Story Mission could prevent players from progressing.
  • Fixed an issue where players using a paid Light Helo Infil could be eliminated by SAM Sites at the Chang-san Military Base shortly after spawning.
  • Updated the Vault Defend interaction to become available only after the Vault Door has been opened.
  • Adjusted the “Power On” interaction location in X01 to prevent its objective marker from overlapping with the door objective.
  • Addressed an issue in DMZ where Player kills in X01 increased your Bounty Level more than intended.
  • Fixed an issue where The Captain and Colossus enemies could eliminate players in Last Stand who were still eligible to be revived.
  • Fixed an issue where Wheelson Commander turrets could continue rotating after being disabled by DDoS and Shock Stick effects.

Audio

  • Fixed an issue where some turret movement sound effects were missing from the Wheelson Commander in X01.
  • Fixed an issue where the DMZ Orders menu could become stuck displaying a "Please Wait" message after completing all Orders.
  • Fixed an issue where using the Argonaut Killstreak could cause an incorrect Operator portrait to appear in the in-game Squad Widget.

Progression

  • Fixed an issue where the BlackCell Camo Challenge requiring players to get 5 kills without reloading 10 times was not tracking correctly.
  • Fixed an issue where players who had already completed the Season 1 Boss Board Challenge prior to Season 1 did not receive the associated trophy in the FOB.

KNOWN ISSUES

  • Platinum camouflage challenges are not tracking for the Cronen Osprey and CSG-35.
  • We’ve temporarily disabled the Warfighter and Warfighter Prime skins while we investigate an issue.
  • We are investigating reports that players on Steam are encountering a crash at launch after taking the Season 1 update.
  • ↳ Please try first verifying the integrity of your game files via the Steam interface to help eliminate unforeseen issues.
  • ↳ As a final workaround, players can solve this issue by reinstalling Modern Warfare 4 and Warzone. When doing this, a player should first uninstall the game on Steam and also delete the Call of Duty folder in steamapps common folder where Call of Duty was originally installed.
  • ↳ We are working directly with Steam on a resolution.
