MW4 patch notes: November 5-7, 2026

Season 1 opened on November 5, 2026, and each of the two following days brought an update of its own. The launch day is by far the largest; November 7 was a fix day whose known-issues list carries a Steam crash.

The launch-day balance tables run to seventeen weapons; the figures live on the Season 1 tuning page. Earlier notes: October 23-25, October 28, October 29 and October 30.

November 7, 2026

A fix-only day across Multiplayer and DMZ. Two entries stand out: the map voting widget gained support for three map and mode combinations, and the known-issues section documents a Steam crash.

GLOBAL

• Fixed several stability issues across all modes.
• Updated the Operator Selection menu to improve the display of Operator Variants.

MULTIPLAYER

• The Map Voting widget now supports playlists with three map and mode combinations, such as Shransit.
• Battle Pass progress on an individual tier would not roll over to the next tier if the player used a Token.

DMZ

• Addressed several stability issues in X01.
• The DMZ Orders menu could get stuck on “Please Wait” after all Orders.

KNOWN ISSUES

• Platinum camouflage challenges are not tracking for the Cronen Osprey and CSG-35.
• The Warfighter and Warfighter Prime skins are disabled during an investigation.
• Players on Steam are encountering a crash at launch after the Season 1 update. Activision asks players to verify their game files through Steam first, and gives reinstalling the game as a workaround. The notes give no date.

November 6, 2026

The smallest of the three, carrying a rule change to DMZ stealth items.

MULTIPLAYER

• New playlist Shransit: Shipment, Shoot House and Transit 213. Hardcore is also available via Quickplay.
• Fixed a brief freeze when editing a Loadout for the first time during a match, and Loadouts could break after Prestiging.

Damage Recap

The recap now displays more combat information: health restored by Quick Fix, damage through surfaces, outgoing damage to multiple enemies, and Bomb Squad damage reduction.

DMZ

• The Thermal Padding trait, its Pro variant and the Sedative Inhaler consumable now correctly hide players from UAVs and UAV Towers with the UAV Upgrade trait. The AUAV Fire Support still detects players using them, which the source calls deliberate: “The goal with this change is to Keep Thermal Padding and Sedative Inhalers as powerful stealth items against standard UAVs. The AUAV Fire Support remains the main counter to these items.”
• Addressed additional exploits in DMZ, and clarified the FOB Trait descriptions for Auto Fill, Impact Smokes Pro and UAV Upgrade.
• The BlackCell Login Reward day counter started at Day 0, not Day 1.

LIVE ISSUES

Infinity Ward directs players to its Trello board and CODUpdates for outstanding problems.

November 5, 2026

Season 1 launch day. The launch notes came separately from an “Additional November 5 Updates” block carrying the launch-day fixes and exploits.

Season 1 launch

• Maps — Backstab (a snow-covered town), Canyon (open spaces and natural terrain), Shoot House (returning in a new setting) and Kill Block: Crash (a featured 6v6 combo) join the rotation.
• Modes — Grind returns, where players collect and bank Dog Tags to score; Drop Zone puts teams in control of a rotating objective for Killstreak drops; Gauntlet 1v1 is Coming Soon.
• New Weapons — Cronen Osprey (AR), “Precision-engineered for relentless performance, this 5.56 rifle delivers a best-in-class fire rate without sacrificing control, accuracy, or mobility,” and CSG-35 (SMG), “Dual-wield akimbo CSG-35 SMGs and trade accuracy for a wave of downrange chaos.” Two more weapons and new attachments join the armory over Season 1.
• Battle Pass — a streamlined, linear 100-tier Battle Pass that catches players up to the reward matching the current day of the Season, up to Day 50. Rewards include two new Base Weapons, Operator Skins, Weapon Blueprints and DMZ Survival Kits.
• Events — Threat Briefing: Battle Tank asks players to destroy Battle Tank threats in DMZ and loot and exfil armor fragments. The Wager Match event is Coming Soon, with Trophies as currency.
• GLOBAL — “Performance Mode (120Hz)” is open to all PlayStation 5 and Xbox Series X|S players with 120hz displays, regardless of VRR support. Activision also names Warzone Agent as an unauthorized paid third-party app that enables “lobby shopping”: from Season 1, players running it lose Multiplayer access unless they close it, and may face temporary or permanent account and/or hardware bans.
• DMZ — X01 is a new Exclusion Zone and underground GRANIT Arms black site beneath Hajin, with new areas, additional Orders, new threats and equipment, an in-world 3D Printer, and “Additional X01 intel remains [CLASSIFIED].” The FOB gains updated Boss Board intel and a vendor update adding weapons and gear purchasable with DMZ Cash for S1 BlackCell owners.

Balance and fixes

• Reduced maximum health in Hardcore modes from 30 to 22.
• Argonaut health increased from 800 to 1,200; Crossfire gained spawn protection, bullet radius cut 25% and bullet damage 50%.
• Prox Mine arming time cut from 1.5 seconds to 0.75 seconds; Claymore arming time from 1 second to 0.75 seconds, forward triggerable range from 2.29 meters to 3.18 meters, and triggerable cone from 60 to 80 degrees.
• The Possum Trait lockout radius increased by 2.5x and its failsafe timer lengthened from 4 minutes to 5; Supplied Drops applies to Dynamic Operations crates, with the chance of an extra container rising from 25% to 50%.
• Weapon XP from vehicle kills against enemy AI was lowered; Operator kill XP is unchanged.
• Closed an exploit allowing Proximity Mines on Seeker Drones, an out-of-bounds exploit at Wolves Stadium in Combat Outpost, and several DMZ duplication exploits. Gunsmith now warns when changing Receivers that the change may affect weapon appearance or functionality.

What Activision did not publish

• Gauntlet 1v1 and the Wager Match event are both labeled Coming Soon, with no date. The same applies to the two additional weapons and new attachments, promised only “over the course of Season 1,” and to the mid-season modes.
• X01’s additional intel is published as [CLASSIFIED]. No POI, threat, Order or loot list for X01 is given.
• The tuning tables give damage profiles and the ranges in metres over which each tier applies. Time to kill, recoil pattern and effective range falloff are unpublished.
• The reduction of Hardcore maximum health from 30 to 22 is stated without a reason, and the Steam crash is listed without a cause and without a fix date.
