What Are the JAK Cataclysm Unlock Requirements in MW3?

The JAK Cataclysm is unlockable through the weekly challenges system in MW3. If you have ever unlocked an Aftermarket Part through this system, you already know how to unlock the JAK Cataclysm. All you have to do is complete five challenges in week two across multiplayer, Warzone, or Zombies, and the Aftermarket Part is yours.

Week two features eight challenges for each game mode, making for a total of 24 challenges. You simply have to complete five of those 24 challenges. They can be split up in any way you want, so you can complete two in multiplayer, two in Warzone, and the final challenge in Zombies, for example. Or, you can complete all five in multiplayer, it’s up to you. Once your five week two challenges are finished, the JAK Cataclysm is yours.
