How to use the JAK Purifier attachment in MW3 and Warzone

Season one of Modern Warfare 3 has brought a new battle pass—but this time, Sledgehammer have thrown in a top-of-the-list item, the JAK Purifier AMP flamethrower.

Burn your enemies to a crisp with the popular under-barrel attachment which has been seen in Call of Duty titles previously but made its MW3 debut with the season one battle pass. How do you unlock it, and what weapons can the JAK Purifier AMP flamethrower be used with?

What is the JAK Purifier attachment in MW3?

The JAK Purifier attachment is an underbarrel flamethrower that can be equipped on certain guns in MW3 and Warzone. It deals fire damage to enemies, burns them with damage over time, and can be used in addition to the weapon’s primary fire functionality.

How to unlock the JAK Purifier in MW3 and Warzone

The JAK Purifier AMP under-barrel MW3 flamethrower attachment can be unlocked via the season one Battle Pass, specifically by completing sector A14. It is possible to skip other sectors of the Battle Pass and jump straight to A14 if you want to unlock the MW3 flamethrower straight away.

To skip sectors of the Battle Pass:

1. Head to the Battle Pass tab at the top of the main menu
2. Click the “Auto” button at the bottom of your screen.
3. Then, select the “Off” option and return to the Battle Pass to select A14 as your active segment.

This way, any early season XP gains will go straight toward unlocking the MW3 flamethrower. Once you hit level five in the sector, it will be completed and you’ll get your hands on the JAK Purifier AMP.

JAK Purifier weapons in MW3

The JAK Purifier AMP flamethrower is only available as an attachment with a certain selection of weapons including, assault rifles, battle rifles, and shotguns. Those hoping they can slap the flamethrower on their sidearms or melee weapons, you’re out of luck—but that sounds like a cool idea anyway.

The list of weapons that can use the JAK Purifier AMP flamethrower includes:

The flamethrower may be made compatible with future weapons in MW3’s life cycle as more are eventually released, so check back in to see whether you’ll be able to light your enemies on fire with your favorite gun.
