Call of Duty: Modern Warfare 3 – How To Unlock Every Multiplayer Weapon Camo

Unlock this year’s Interstellar mastery camo by completing these Modern Warfare 3 Multiplayer camo challenges.

In terms of sheer volume, this is the largest Season 1 content drop any Call of Duty game has seen in recent memory. To help you prioritize which items to unlock first, this guide will explain every new item introduced to core Multiplayer and how to unlock it, ranging from new weapons to this season’s unique Aftermarket Parts.


Season 1 Weapons

Modern Warfare 3 HRM-9 SMG

Modern Warfare 3’s first season has five new weapons to earn, two of which will be added in a mid-season patch: The RAM-7, XRX Stalker, and Stormender are earnable through the Season 1 Battle Pass. Once the season ends, these weapons will become obtainable through an in-game challenge. The HRM-9 and TAQ Evolvere will become available later in the season.

Battle Pass (A7)

Weapon Inspiration

IWI Tavor

The RAM-7 can be obtained from Sector A7 of the Season 1 Battle Pass. It’s identical to its MW2019 version, featuring exceptional handling stats for its archetype and a respectable damage profile. Visual recoil on the RAM-7 is quite aggressive, however, so building this weapon for accuracy is highly recommended.

XRX Stalker

Modern Warfare 3 XRX Stalker Sniper

Battle Pass (A4)

Weapon Inspiration

Remingston MSR

The XRX Stalker is found in Sector A4 of the Season 1 Battle Pass. It is a reimagined version of the original Modern Warfare 3’s Remington MSR, a sniper rifle that was renowned for its high base damage and quick rechambering speed. It’s statistically comparable to MW2’s MJX Imperium, otherwise known as the Intervention.

This weapon has an excellent damage profile that allows for one-taps from the lower torso and up. It also has a fairly quick rechambering speed of 1.6 seconds and ADS time of 610ms, modifiable through attachments.

Stormender

Battle Pass (A12)

Weapon Inspiration

Unknown

The Stormender is a new launcher weapon that’s available from Sector A12 in the Season 1 Battle pass. This weapon has a battery-powered magazine that fires lock-on EMP rounds, instantly destroying smaller electronics while disabling larger devices. It does no damage to players.

A single shot from the Stormender can destroy player equipment, UAVs, Counter-UAVs, Sentry Guns, and even Cruise Missiles. And since this weapon doesn’t fire kinetic projectiles, it never has to reload since its ammo is generated passively. It’s the ultimate counter to low-requirement killstreaks and player equipment.

HRM-9

The HRM-9 is MW3’s take on the Beretta PMX SMG. This weapon will become available after the mid-season patch releases on January 17.

The TAQ Evolvere is a new LMG coming to MW3 after the mid-season patch releases on January 17. It appears to be inspired by the FN Evolys.

Perks And Killstreaks

Modern Warfare 3 Season 1 Killstreak Collage

Season 1 has added one new vest and two killstreaks for players to use in Multiplayer. All three of these items are obtained from the Armory Challenges system, unlocked at Level 25. You will need to track the items through the Armory Challenges UI and complete daily challenges to unlock these new items.

Assassin’s Vest

Modern Warfare 3 Assassin's Vest

Properties

Immune to UAV and enemy radar effects (including while stationary).


Kills don’t display skulls.

Loadout Slots

Equipment: x1 Tactical, x1 Lethal, no Field Upgrade

Perks: x1 Gloves, x1 Boots, x1 Gear

Source

Armory Challenges (3 Daily Challenges)

The Assasin’s Vest is acquired through the Armory Challenges system. You must complete three daily challenge objectives to unlock this item. This vest trades your Field Upgrade slot for a buffed version of the Ghost perk.

This version of Ghost does not reveal your location while stationary, making this vest perfect for all stealth builds. It also hides death skulls from enemies you kill to further your stealth effectiveness. Pair this vest with a suppressed weapon to remain completely hidden from enemy radar.

EMP

Modern Warfare 3 EMP Killstreak

Properties

Destroys all enemy killstreaks and equipment.


Enemies have no HUD for 30 seconds.

Kill Requirement

13 Kills or 1,625 Score

Source

Armory Challenges (8 Daily Challenges)

The EMP killstreak can be unlocked through the Armory Challenges system, requiring eight daily challenge completions. This killstreak works identically to how it behaved in the original MW2 and MW3. When activated, an EMP will cover the map and destroy all enemy electronics, including any active killstreaks.

After the EMP is used, the enemy team will lose all HUD elements for a short period. This includes team identifiers, making it incredibly difficult to discern friend from foe.

Swarm

Modern Warfare 3 SWARM Killstreak

Properties

Creates dozens of Mosquito Drones that linger for 45 seconds, targeting any enemies outside.


Players can counter this perk with Hijacked IFF Strobe (Cold-Blooded)

Kill Requirement

15 Kills or 1,875 Score

Source

Armory Challenges (8 Daily Challenges)

Black Ops 2’s Swarm killstreak has returned in Modern Warfare 3, obtained from the Armory Challenges system after completing eight daily challenges. While the Swarm has the highest kill requirement out of any killstreak, it also has the highest kill potential out of any MW3 killstreak.

Shortly after calling in the Swarm, hundreds of Mosquito Drones will fill the skies and begin to target enemy players. Any players caught outside and without the Hijacked IFF Strobe will be repeatedly targeted by Mosquito Drones. The swarm lasts for roughly 45 seconds before the drones self-destruct. Excluding Cold-Blooded, the only way to counter the Swarm is with the EMP killstreak.

Aftermarket Parts

Modern Warfare 3 Season 1 Aftermarket Parts Collage

Nine Aftermarket Parts are available during Modern Warfare 3’s first season, most of which are obtainable through the Weekly Challenge system. Completing five challenges within a given weekly set will unlock that week’s listed attachment. These challenges are available until the end of the season, at which point all Aftermarket Parts you missed will be obtainable through an in-game challenge.

JAK Purifier

Modern Warfare 3 JAK Purifier Flamethrower Attachment

Category

Underbarrel

Effect

Adds an underbarrel flamethrower.

Source

Battle Pass (A14)

Compatible With

MW3 Assault Rifles & Battle Rifles

The JAK Purifier is an underbarrel flamethrower that’s earned through the Season 1 Battle Pass in Sector A14. This weapon deals fairly low damage per hit and can reach out to eight meters. It has an ammo capacity of 300 and cannot be reloaded.

It’s not a particularly strong attachment in Multiplayer, but the flamethrower is a great utility weapon in Zombies. MWZ targets hit by the flamethrower will be temporarily staggered, and each tick of the flamethrower can trigger elemental ammo properties from the installed weapon or the Elemental Pop perk.

JAK Ettin Double Barrel Kit

Category

Barrel

Effect

Installs a second barrel onto the AMR9, doubling its effective fire rate.

Source

Weekly Challenge

Compatible With

AMR9

The JAK Attin Double Barrel Kit allows the AMR9 to fire twice as many bullets per trigger pull by installing a second barrel. This comes at the cost of accuracy. You can earn this weapon through a Season 1 Weekly Challenge.

JAK Thunder LMG Kit

Category

Conversion Kit

Effect

Turns the Sidewinder into an LMG.


This weapon gains fire rate as you hold down the trigger.

Source

Weekly Challenge

Compatible With

Sidewinder

If you can’t stand the Sidewinder in core Multiplayer, the JAK Thunder Kit converts this weapon into an LMG with a higher potential RPM. The weapon gains a drum mag and a modified receiver, increasing the weapon’s fire rate the longer you hold down the trigger. You can earn this conversion kit through the Weekly Challenge system during Season 1.

JAK BRB

Category

Muzzle

Effect

Substantially reduces recoil.


Your weapon now creates a longer-lasting ping on enemy radar.

Source

Weekly Challenge

Compatible With

Most Primary Weapons

This attachment provides a substantial reduction to your weapon’s gun kick, horizontal recoil, and vertical recoil stats. As a consequence, this attachment causes your minimap icon to persist much longer for enemy players, making this attachment ill-suited for stealth builds. You can earn this muzzle from a Weekly Challenge during Season 1.

JAK Bullseye

Category

Optic

Effect

Adds a low-profile reflex optic.

Source

Weekly Challenge

Compatible With

Most Weapons

The JAK Bullseye adds a red-dot sight that has an incredibly thin frame, making this a great optic for most weapons. This optic will become available through a Season 1 Weekly Challenge.

JAK Glassless Optic

Category

Optic

Effect

Adds a glassless reflex optic.

Source

Weekly Challenge

Compatible With

Most Weapons

Similar to the JAK Bullseye, the JAK Glassless Optic is a close-range optic that uses a glassless design to create an extremely clear optic. You can earn this optic from a Weekly Challenge during Season 1.

The Holger 556 now fires in four-round bursts. Greatly increases accuracy.

Weekly Challenge

Compatible With

JAK Headhunter Carbine Conversion

Modern Warfare 3 Rival-9 Headhunter Carbine Kit

Category

Conversion Kit

Effect

The Rival-9 now fires in three-round bursts. Greatly increases range and recoil control.

Source

Weekly Challenge (Week 1)

Compatible With

Rival-9

Available from the first Weekly Challenge in Season 1, the JAK Headhunter Carbine Conversion turns the Rival-9 SMG into a three-round burst rifle. Equipping this conversion kit increases the Rival-9’s damage to 33 per shot, decreases the fire rate to 215 bursts per minute, and dramatically increases the weapon’s effective range.
