Infinity Ward's November 7 update fixes Battle Pass token progress and DMZ bugs. Here are the known issues and the official workaround for Steam launch crashes.

Infinity Ward's November 7, 2026 update for Modern Warfare 4 Season 1 addresses Battle Pass progression, Multiplayer and DMZ problems. Steam launch crashes remain under investigation: the steps below are an official workaround, not a guaranteed fix.

Main fixes

• Battle Pass: tier progress now carries over to the next tier when a Token is used.
• Hardcore: fixes getting stuck on the scoreboard at the end of a match.
• Multiplayer: Field Upgrades no longer disappear on certain Lithium surfaces; Grind objectives spawn correctly in Private Match; an Operator's elimination no longer ejects the player from the Gunship killstreak.
• DMZ/X01: stability improvements and a correction for player kills increasing Bounty Level more than intended. The Captain and Colossus no longer eliminate revivable players in Last Stand. Destroying the boat early no longer blocks Operation Fallen Ember. The Orders menu no longer stays on Please Wait.
• Progression: the BlackCell camouflage challenge requiring five kills without reloading ten times now tracks correctly.

Known issues, not resolved by this patch

Platinum camouflage challenges for the Cronen Osprey and CSG-35 are not tracking. Warfighter and Warfighter Prime skins are temporarily disabled. Infinity Ward is investigating Steam crashes at launch after the Season 1 update and says it is working with Steam on a resolution.

Steam launch crash: start with file verification

First verify the integrity of the game files in Steam. If the crash persists, the official notes give a last-resort reinstall workaround: uninstall the game in Steam, remove only the remaining Call of Duty folder from its original steamapps/common installation location, then reinstall.
Warning: uninstalling and deleting this folder removes local installation files and requires another download. Back up any local files you wish to keep before deletion; never remove the whole steamapps/common folder. If you are unsure which folder is correct, do not delete anything and contact official support. We have not personally tested this procedure; it does not guarantee that the crash will be resolved.
