NEW MAPS
Season 3 introduces a total of six 6v6 Multiplayer maps to Modern Warfare III.

NEW WEAPONS
Progress the Battle Pass to unlock four base Weapons, including the iconic MORS and BAL-27 from Call of Duty: Advanced Warfare (2014).

FJX Horus (Submachine Gun)

An ultra-compact SMG with best-in-class CQC damage and mobility.

MORS (Sniper Rifle)

This single-load railgun delivers a high-damage payload with excellent velocity and penetration.

Gladiator (Melee)

A compact, concealable punch knife that was initially used by gamblers and politicians.

BAL-27 (Assault Rifle, In-Season)

A bullpup prototype weapon designed to increase fire rate over time while the trigger is squeezed. The first 4 shots are slower to fire but highly accurate.

NEW AFTERMARKET PARTS
Add some spice to previously mastered weaponry with eight all-new Aftermarket Parts.

JAK Cutthroat

This 3D-printed stock provides an unrivaled combination of speed and stability while aiming down sights.

JAK Revenger Kit

This conversion kit turns the BP50 into a CQC legend. A 9mm caliber conversion with shortened receiver and high-capacity magazine.

JAK Jawbreaker

Converts this Shotgun into a hard-hitting, automatic Battle Rifle.

JAK Shadow Titan Kit

Converts the Bruen Mk9 into a compact and integrally suppressed light support weapon chambered in 300 blackout.

JAK Patriot

Converts the M16 into a fully automatic rifle with a heavy ported barrel built to provide superior recoil control and firing aim stability.

Wardens

Relive the glory days, stir up the hornet’s nest, and take down your enemies, leaving no loose ends with these museum-worthy akimbo lever-action Shotguns.

JAK Atlas Kit

Converts the AMR9 into an extremely lethal and accurate 5-round burst carbine chambered in 556.

Photonic Charge Barrel

This hyper-advanced barrel is more than simply a barrel. Holding the trigger charges the rifle and releasing fires a single, high-power energy projectile.

NEW EQUIPMENT
Try fresh tactics with two new Equipment items arriving later in the Season.

EMD Mine (Tactical, In-Season)

Proximity-triggered mine that sticks to surfaces. Once triggered, the mine shoots out tracker devices that reveal the enemy location and direction until removed.

GLOBAL
CUSTOMIZATION
Corrected protection with the Aegist Imperials Blueprint to match the base Riot Shield.

Resolved an issue causing Blueprints to lose aesthetics when saved as a Custom Mod.

MULTIPLAYER
UIX
Added an unlock status and game origin filter for Operators and the ability to sort by latest additions and name.

Added a new option to the Settings menu to test all speakers in the current audio setup.

Seasonal cinematic cutscenes can now be skipped.

Tac-Stance status is now indicated on the HUD in the Firing Range.

Weapon Mastery Emblem unlock requirements are now displayed in the Customization menu.

Adjusted various Attachment descriptions and Pros/Cons listed in the Gunsmith to better reflect their true attributes.

Gunsmith Attachment Filters

Changed filter combination logic from AND to OR.

Bug Fixes

Resolved an issue preventing certain Emblems from being added to Favorites.

GAMEPLAY
Decreased obstructive VFX while firing MWII Weapons to align with MWIII standards.

Removed variance from ADS Idle Sway, allowing a predictable sway pattern.

Our next step toward improving the feeling of aiming across all input devices in Modern Warfare III arrives in Season 3. As previously detailed, aimed down sight idle sway discourages players from holding their sights for an extended period of time with a constant, subtle motion that introduces slight inaccuracy.

In today’s update, we’ve removed variance from aimed down sight idle sway, resulting in a predictable and consistent motion curve. This change raises the skill ceiling and rewards players who take the time to master their favorite Weapons.

PROGRESSION
Added Party Bonus XP, allowing players to earn more XP dependent upon the party size.

2 Players: +25% Rank and Weapon XP

3 Players: +25% Rank, Weapon, and Battle Pass XP
