Call of Duty: Modern Warfare 3 Season 4 is now live and brings a variety of new content to the game's Multiplayer and Zombies modes. To learn more about the changes, check out the latest patch notes below.
I like how Sledgehammer Games has handled MW3 by continuously adding fresh content and keeping the game enjoyable. Besides the new weapons, maps, and game modes, Season 4 also added some weapon balancing, bug fixes, and quality-of-life improvements. A minor update has been pushed on all platforms just a week after the big content drop that addresses some minor bugs and issues.

Modern Warfare 3 Patch Notes - May 29
Season 4 Content
NEW MAPS
The fog of war goes global. Take to the streets of Tokyo and Paris at the launch of Season 4, then look for desolate and disgusting arenas later in-season.
NEW MODES
Several new and fan-favorite Modes debut in MWIII in Season 4. Look out for weekly Playlist Updates to know when your favorite Modes arrive.
NEW WEAPONS
Alongside returning icons, fresh new weaponry is on the horizon in Season 4.
Kar98k (Battle Pass, Marksman Rifle)
This modernized version of a WWII bolt-action rifle is powerful and accurate. High damage output with a slow rate of fire.
Superi 46 (Battle Pass, Submachine Gun)
This pistol-caliber carbine chambered in 4.6x30mm is designed to give impressive stopping power with a skeletonized, lightweight frame. Exceptionally adaptable, this weapon can be modified to excel in most combat scenarios.
Reclaimer 18 (Battle Pass, Shotgun, In-Season)
A tactical shotgun that can be fired in both pump-action and semi-auto modes. Pump-action provides superior range while semi-auto increases fire rate.
Sledgehammer (Weekly Challenge, Melee, In-Season)
Smack some heads with this hammer claw bar Melee weapon with unique attack modes.
NEW AFTERMARKET PARTS
Eight all-new Aftermarket Parts arrive throughout the weeks ahead in Season 4. Every one of which is a fully-fledged conversion kit for fan favorite weaponry.
JAK Harbinger Kit (M4 Assault Rifle)
This .50 Cal conversion kit for the M4 is an extremely deadly, quick-kill weapon. The slow fire rate, drop in bullet velocity, and a significant increase in recoil will require a careful hand.
JAK Gunslinger (Basilisk Handgun)
A frame and cylinder conversion that allows the revolver to hold eight rounds of .357 ammunition with an exceptional increase to rate of fire and a near instantaneous trigger action.
JAK Volkh (KV Inhibitor Sniper Rifle)
A meticulously crafted stock and receiver modification that updates the weapon to fire a two-round burst at minimal MOA dispersion, making every trigger pull count.
JAK Scimitar Kit (FJX Horus Submachine Gun)
Improved range and recoil are standard with this aftermarket kit which also unlocks the use of a high-capacity drum mag for the FJX Horus.
JAK Thumper-656 (RGL-80 Launcher)
An improved long barrel for an infantry-carried grenade launcher. Fires projectiles at higher velocities and distances. Compatible with a wider variety of launcher projectiles.
JAK Requiem (Kastov 762 Assault Rifle)
A counter-balanced rifle system designed to completely eliminate vertical recoil.
JAK Decimator (Lachmann Shroud Submachine Gun)
This modification allows the Lachmann Shroud to fire in full auto.
JAK Intimidator (Renetti Handgun)
Slow down your fire rate and take more deliberate shots with this modification that changes the Renetti to a single-shot weapon.
NEW KILLSTREAKS
Powerful new armaments join the Killstreaks arsenal in Season 4.
Loitering Munition - 8 Kills (1,000 Score)
An unmanned rocket equipped drone loiters over the targeted areas. On each activation the drone selects the targeted location with the largest number of viable targets to bombard with rockets. Can be activated up to three times.
I.M.S. - 7 Kills (875 Score)
The Intelligent Munitions System is loaded with 4 smart explosives that eliminate enemy personnel and vehicles within range. When triggered, it will eject an explosive upwards, which then locks onto its target and propels towards them.
Missile Drone - 11 Kills (1,375 Score)
Piloted drone that fires guided missiles.
DNA Bomb - 25 Kills
Call in a DNA altering bomb that eliminates the entire enemy team without ending the match.
NEW PERKS
Tailor Loadouts to your playstyle with new Vest and Gear Perks.
Mission Control Vest
Duplicate effects do not stack. If equipped with Mission Control Comlink, gain the effects of High Gain Antenna.
Compression Plate (Gear)
Immediately regen health after a Primary, Secondary, or Throwing Knife/Star kill. Objective captures also trigger health regen.
NEW OPERATORS
Mysterious new figures join Kortac and Specgru in Season 4. Which side are you on?
Void
A Jane Doe, nicknamed Void, has a mysterious mutation that alters her memory. Further study is needed. She remains under close surveillance.
Hammer
Manoel was the youngest of three siblings by a large margin. Growing up, he was often called the “accident,” though his father would assure him that yes, he may have been an accident, but he was a happy one.
When Manoel was twelve-years-old, and his siblings long gone from the home, his father gifted him a puppy – a Brazilian Mastiff, to name and care for.
Manoel named the puppy Hammer, and they did everything together. Wanting to be with Hammer for as long as possible, Manoel trained him as a working dog, and enrolled in the military with Hammer by his side. First, he was part of the Guard Battalion utilizing Hammer as a guard dog, and later, moved his way into the Brazil Special Operations where Hammer’s hunting and tracking skills became invaluable in chasing down targets.
One day, on a tracking mission, Hammer was killed in action by the SpecGru organization. Manoel took Hammer's name as his own callsign, and vowed revenge. He joined KorTac to do it and promised to never work with another K-9 unit, and to avenge his dog.

Last season, we made several adjustments to Perks to distribute usage in the Boots category more evenly. Despite these changes, the pick rate of Covert Sneakers remains far ahead of other Boots.
In today’s update, our Design and Audio teams have decreased the volume of all footstep types (walk, sprint, and tac-sprint) to encourage more diverse usage in the Boots category of Perks.
