…and more 🙂


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.



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 Atlas Kit

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

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

Our next step toward improving the feeling of aiming across all input devices in Modern Warfare III arrives in Season 3.

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.
