What is the JAK Purifier attachment in MW3?

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.
