Call of Duty: Modern Warfare 4 Update — October 28

Today's update brings more fixes and improvements across Multiplayer and DMZ.

In Multiplayer, we have our first weapon tuning update. We’ve also addressed issues with Challenges, Killstreaks, the Quick Fix Perk, and general gameplay.

For DMZ, we've closed exploits and resolved some issues with Loadouts and Exfil.

We're continuing to monitor your reports, prioritize fixes, and roll out improvements across Modern Warfare 4. Keep the feedback coming, and we'll keep the updates rolling.

PLAYLIST

A note on FFA: Yesterday we noticed that FFA matches were often going to time. We made a quick tweak to the score limit to help with this, and we've seen the feedback on that. We've adjusted the score limit back to 30 for our FFA mains, and in a later backend update we will restore Final Killcam, as it has been in recent MW titles.

GLOBAL

MOVEMENT

We are aware of a movement exploit where the player can immediately dive after a sprint jump to gain a boost of speed. To mitigate this short-term, we have reduced the dive's velocity by 23%. We are working on a long-term solution to fully fix this exploit in a way that the dive's velocity would not be impacted. We'll share more in a future update.

UI/UX

• Fixed an issue where progress counters were missing from Camo and Special Camo unlock requirements across several weapon categories.
• Fixed an issue where the Fungal Grid Camo was not visible in the Camo selection menu.
• Fixed an issue where, in match, the Tracked & Near Complete Camo menu would not automatically track the next Camo Challenge after unlocking a Camo.
• Fixed showing military Camos as locked after the player has Prestiged the weapon.
• Fixed an issue where Prestiging from the DMZ FOB would not correctly reset Multiplayer Loadouts.
• Fixed an issue where Calling Card unlock requirements could overlap with the progress bar.
• Fixed an issue where the Crossfire and Argonaut Killstreaks displayed incorrect icons in the Multiplayer Killfeed.
• Fixed an issue on PC where players could not click and drag the scrollbar in the Tracked & Near Complete Calling Cards menu.
• Fixed an issue where removing an attachment from a Blueprint and then re-adding it would not restore its unique visual while still in the menu.

MULTIPLAYER

Our first broad weapon tuning pass is focused on normalizing hit location damage for a more consistent TTK and general improvements to SMG performance.

Edited for clarity: As mentioned above, normalized hit locations were a focus of this update. These changes primarily targeted upper limb damage multipliers for Submachine Guns.

BUG FIXES

• Fixed a visual issue where the Mosin-Nagant's firing pin could appear in the incorrect position after firing the final round.
• Fixed an issue where taking damage would not interrupt health regeneration from the Quick Fix Perk.

We noticed an issue where Quick Fix would continue to regenerate health even after taking damage. This was causing players to be more tanky than intended. Damage will now properly interrupt Quick Fix.

• Addressed an exploit involving the Riot Shield entering out of bounds areas.
• Improved the visibility of UAVs on Sentry.
• Fixed an issue where certain Melee Kills, Backstabs, and Takedowns were not tracking correctly for some Challenges.
• Increased the maximum range cutoff for Point Blank Challenge tracking.
• Decreased the minimum range cutoff for Longshot Challenge tracking.
• Fixed an issue where players would incorrectly appear as Reece when loading into Gun Game, regardless of their selected Operator.
• Updated the Quick Fix Perk hitmarker icon.

DMZ

The intention for Possum is to give a high level operator a second chance. With the current iteration, Possum was being used as a combat mechanic instead of a survival mechanic. These tweaks are meant to prevent players from getting right back into the fight which they had just lost. We will be watching the use of Possum with this change to see if it has the desired effect.

• We’ve adjusted the Possum Trait so that you are now unable to activate Possum while the team that killed you is nearby or until 4 minutes have passed. This range and duration is tunable going forward.
• Addressed a bug where Possum could revive players who had already abandoned their Operator, which would put them in an unplayable state.
• Fixed an issue where players could encounter a black screen after their entire squad was eliminated while a teammate had the Possum Perk equipped.
• Fixed an issue where using the 3D Printer to add items to the Backpack during deployment could cause players to deploy into DMZ without their Free Loadout weapons or equipment.
• Closed several exploits in DMZ.
• Fixed an issue where weapons could unintentionally drop when moving them from the Primary Weapon slot to the Backpack.
• Fixed an issue where players were not receiving the 3-Plate Armor Vest reward upon reaching DMZ Level 37.
• Fixed an issue where weapons could disappear after repeatedly swapping between weapon slots while using a Backpack with weapon storage.
• Fixed an issue where the Airbase Access Card could not be upgraded during a Story Mission if it was stored in the Secure Slot.
• Fixed an issue where automatically marked Order mission items could lose their Ping markers after players pinged a loot container.

KNOWN ISSUES

• We're aware of an issue where the Patriot XMR Platinum Camo Challenge is not tracking correctly in the UI. The challenge can still be completed and progressed despite not displaying accurately. We are working on a fix.
• We're investigating some Calling Card challenges not tracking as intended.
• We're aware of an issue with Best Play selection logic in Multiplayer modes.
• Players who enter Classic Prestige via DMZ menus instead of MP menus are unable to make new MP classes until previously created MP classes with relocked Loadout items are deleted.
