Which Weapons Are Stronger after October 28 CoD MW4 Update?

PublishedPublished: Oct 29, 2026

Since the release of CoD MW4, the official team has been rolling out patches at a rapid pace, with updates arriving daily from October 23 through October 25. On October 28, the team released a particularly significant update.

The update covers both Multiplayer and DMZ, featuring weapon tuning, bug fixes, adjustments to challenges and killstreak rewards, general DMZ gameplay improvements, and the closure of several exploit methods.

Playlist

As for the playlist, Shipment, Frontline, Inflation, Collateral, Kill Block, and Gun Game had already gone live the previous day.

Free-for-All score limit remains at 30, but the maximum party size has been reduced from four players to two. This change is hardly surprising, as four-player parties could easily become a way to boost scores. Reducing the limit to two is a reasonable restriction.

Global Fixes

In the global update notes, the official team acknowledged a movement exploit that allowed players to gain extra speed by diving immediately after a sprint jump.

The team has not fully resolved this issue yet. As a short-term mitigation measure, dive speed has been reduced by 23%. This means regular dives will also be affected to some extent in the meantime.

The update also includes numerous UI/UX fixes, including missing camouflage and special camouflage unlock progress counters for certain weapon categories, military camos incorrectly appearing locked after Weapon Prestige, and Calling Card unlock requirement text overlapping with progress bars.

First Round of Weapon Tuning in Multiplayer

Multiplayer has received its first extensive round of weapon tuning, with a focus on standardizing hit location damage, making TTK more consistent, and improving SMG performance across the board. This is also one of the most closely watched aspects of the update.

The specific changes include:

Han 86's maximum damage range has been increased, but its neck and upper torso damage multipliers have been reduced;

The maximum damage ranges of Kastov 762 and M4 have been increased;

ODEN's neck and torso damage multipliers have been reduced, while the maximum and medium damage ranges of Sentinel Apex Attachment have been decreased;

Hyeon Burst's maximum damage in full-auto mode has been slightly reduced, while its maximum damage range has been slightly increased. Its medium damage range has been removed entirely;

The recoil control penalties for Patriot XMR's Haste Barrel and Fury Grip have both been reduced, which should make these attachments easier to control in practice.

PPSh-41's ADS speed value has been adjusted from 300 to 280. Its horizontal movement, crouch movement, hip-fire, general movement, and sprint speeds have also been improved, along with its damage multipliers, resulting in more consistent overall performance.

VEL 46, Wz.55 Striga, X-58 Nyx, and ISO Nightshade have received similar across-the-board improvements to PPSh-41, making their TTK performance more consistent.

APOC-338 has been significantly nerfed, with its medium damage, medium damage range, and minimum damage, which applies at long range, all reduced.

FiNN LMG's medium damage range and arm damage multiplier have been reduced;

Type 73 has received a long-range damage increase;

Warlord's medium damage range has also been reduced when using Slugs.

If you haven't completed the camo challenges for certain weapons yet, consider using the buffed weapons listed above to make progress faster. You can also buy MW4 Bot Lobbies to level them up more quickly.

Multiplayer Bug Fixes

Multiplayer fixes include correcting the inaccurate firing ping indicator for Mosin-Nagant and resolving an issue where taking damage did not interrupt health regeneration from Quick Fix. Previously, this allowed Quick Fix to become excessively powerful while restoring health, making this an important fix.

The official team has also addressed an exploit involving Riot Shield and improved UAV visibility on Sentry map, where snow and fog made the aerial reconnaissance device difficult to see.

Issues preventing certain melee kills, backstabs, and executions from being tracked have been fixed. The maximum distance threshold for Point Blank kills has also been increased.

Additionally, the team has fixed an issue that sometimes caused players to be incorrectly displayed as Reece and updated the hit marker icon for Quick Fix perk.

DMZ Mechanic Adjustments and Fixes

CoD Modern Warfare 4 Possum
CoD Modern Warfare 4 Possum

In DMZ, Possum was originally designed to give high-level Operators a second chance. However, in its current form, it has functioned more like a combat mechanic than a survival mechanic.

The latest adjustment aims to prevent players from immediately returning to combat after being eliminated. Possum can no longer be activated if the squad that eliminated you is still nearby or if four minutes have not yet elapsed. Its range and duration may be adjusted further in the future.

This is not simply a nerf but something closer to a rework. Possum was often used as a PvP mechanic, whereas its revised role focuses more on tactical re-entry and preventing players from losing their Operators. It remains to be seen whether players will simply wait out the full four minutes or start placing mines on bodies immediately after wiping a squad.

DMZ has also received several bug fixes. For example, Possum could previously revive players who had already abandoned their Operators. Adding items to a backpack with a 3D Printer during deployment could cause players to enter the deployment without their free weapon loadout. Air Base Access Card could also fail to upgrade during story missions, among other issues.

Outstanding Issues

The official team is still investigating several unresolved issues, including a UI bug affecting Patriot XMR's Platinum Camo, problems with certain Calling Cards, and issues with Best Play. Fixes may arrive by the end of this week, early next week, or alongside the launch of Modern Warfare 4 Season 1 on November 6.

Overall, this is a substantial and somewhat unexpected update that will have a noticeable impact on the weapon meta and TTK performance. Hopefully, the changes will make gunfights more consistent across different weapons.
