Key points
- The latest update is November 10, 2026. It fixes the Ghost perk, disables UAVs in DMZ's X01 and adds a Scavenger Bonus for failed exfils.

The newest Modern Warfare 4 update landed on November 10, 2026. It is a round of fixes: the Ghost perk bug is gone, UAVs are switched off in DMZ's X01, and DMZ now pays a Scavenger Bonus when you fail to exfil. The big balance changes came with the Season 1 launch notes on November 5, and they are summarised below from Infinity Ward's official notes.
Season 1 update timeline
| Date | What it was |
|---|---|
| November 5 | Season 1 launch notes: maps, modes, weapons, weapon balancing, plus a second batch of fixes the same day |
| November 6 | Shransit playlist, better Damage Recap, DMZ UAV rule change |
| November 7 | Stability, Battle Pass token fix, DMZ X01 fixes |
| November 10 | Ghost and nameplate fixes, X01 UAVs disabled, Scavenger Bonus |
November 10 update: what changed
Multiplayer
- Ghost could sometimes hide players who fired unsuppressed weapons. Fixed.
- Enemy nameplates could show when the enemy was hidden, or through Care Packages. Fixed.
- Aim-down-sights sensitivity now switches back to hip sensitivity earlier when you leave ADS.
- Match-wide chat is on in Free for All and Gun Game.
- The Cronen Osprey no longer plays an extended animation when you switch to it.
DMZ
- Scavenger Bonus: if you fail to exfil, you now get cash based on the value of what you looted and how long you were deployed. It does not apply to Story Missions.
- X01: UAVs and Advanced UAVs can no longer be deployed there at all. The Mini Tracker trait's radius is slightly smaller.
- Players can no longer get stuck in the X01 Vault Elevator, and explosions under a departing exfil helicopter no longer hurt players on board.
Platinum camo tracking for the Cronen Osprey and CSG-35, which was a known issue on November 7, is listed as fixed.
Weapon buffs and nerfs in Season 1
Most changes are buffs to range or to long-range damage. The standouts:
| Weapon | Change | Verdict |
|---|---|---|
| Axion (AR) | Bullet velocity 415 to 470 m/s, mid range 34.8 to 38.61 m | Buff |
| Kastov 762 (AR) | Mid damage 24 to 25, mid range 40.13 to 42.16 m, headshot 1.33x to 1.35x | Buff |
| M4 (AR) | Max damage range 25.91 to 27.94 m, headshot 1.25x to 1.3x | Buff |
| Han 86 (AR) | Headshot 1.25x to 1.3x | Buff |
| Patriot XMR (AR) | Max damage range 31.24 to 33.53 m | Buff |
| Hyeon Burst (AR) | Base mid damage 24 to 25 | Small buff |
| Hyeon Burst, Hyperbust Apex Attachment | Max damage 30 to 23, min 25 to 20, range 24.64 to 30.99 m | Nerf |
| Wz.55 Striga (SMG) | Max damage 26 to 27, min 17 to 19, headshot 1.3x to 1.4x | Buff |
| VEL 46 (SMG) | Damage ranges down about 4 to 5%, min damage 13 to 14 | Mixed |
| ISO Nightshade, PPSh-41, X-58 Nyx (SMGs) | Higher long-range damage | Buff |
| APOC-338 (LMG) | Min damage 33 to 32, headshot 1.35x to 1.3x | Nerf |
| Type 73 (LMG) | Headshot 1.25x to 1.3x, slightly more range | Buff |
| Rezi 12 (shotgun) | Longer mid ranges, min damage 14 to 16 | Buff |
| Oris 8.6 (marksman) | Max damage range 19.05 to 22.61 m, min damage 58 to 63 | Buff |
| Krait P68 (pistol) | Slightly more range, lower torso 1x to 1.1x | Buff |
What it means: if you were running the Hyeon Burst with the Hyperbust attachment, that build lost about a quarter of its close-range damage. The base rifle is fine. The Kastov 762 and Axion are the assault rifles that gained the most, and the Wz.55 Striga is the SMG to try.
Killstreak and equipment changes
- Argonaut: health up from 800 to 1,200.
- Crossfire: bullet damage cut by 50% and bullet radius by 25%, with spawn protection added.
- Prox Mine: arms in 0.75 seconds, down from 1.5.
- Claymore: arms in 0.75 seconds, down from 1, with a longer trigger range (2.29 to 3.18 m) and a wider cone (60 to 80 degrees).
- Hardcore: maximum health reduced from 30 to 22.
New maps, modes and weapons
- Maps (6v6): Backstab, Canyon, Shoot House and Kill Block: Crash.
- Modes: Grind and Drop Zone return. Gauntlet 1v1 is marked as coming soon with the Wager Match event.
- Playlist: Shransit mixes Shipment, Shoot House and Transit 213.
- Weapons: the Cronen Osprey assault rifle and the CSG-35 SMG, which can be dual-wielded. Two more weapons are due during the season.
- Battle Pass: a linear 100-tier pass that catches you up to the current day of the season, up to day 50.
- Consoles: Performance Mode (120Hz) is now open to all PS5 and Xbox Series X|S players with a 120Hz display, even without VRR.
DMZ: the new X01 zone
X01 is an underground GRANIT Arms facility reached through Hajin, with new Orders, threats and an in-world 3D printer. Since launch the developers have changed how stealth works: Thermal Padding and Sedative Inhalers now hide you from standard UAVs and upgraded UAV Towers, and as of November 10 UAVs cannot be used in X01 at all.
Known issue on Steam
Infinity Ward's November 7 notes say some Steam players crash at launch after the Season 1 update. The suggested steps are to verify the game files in Steam first and, as a last resort, uninstall and delete the Call of Duty folder in steamapps/common before reinstalling.
Also on our radar this month: the GTA 6 release date is eight days away, and Fortnite players can check the next Treasure Hours times and odds.

Frequently asked questions
What changed in the MW4 update on November 10?
It is a fixes update. Ghost no longer hides players firing unsuppressed weapons by mistake, enemy nameplates no longer show through cover, UAVs and Advanced UAVs are disabled in DMZ's X01, and DMZ players now get a cash Scavenger Bonus when they fail to exfil.

Four joined the 6v6 rotation: Backstab, Canyon, the returning Shoot House and Kill Block: Crash. Infinity Ward says more maps arrive later in the season.
