How to unlock the JAK Limb Ripper in MW3 and Warzone

Call of Duty has taken a page out of Gears of War with its latest Aftermarket Part in Modern Warfare 3 and Warzone.

The JAK Limb Ripper Aftermarket Part is something that would make Marcus Fenix very excited because it can turn several guns into a Lancer from the classic third-person shooter franchise.

That’s right, it’s an underbarrel chainsaw that players can use to saw through enemies for quick and easy melee kills—or, even better, to chop down hordes of undead in MW3 Zombies mode.

Here’s how to get the new JAK Limb Ripper Aftermarket Part in MW3.
