Call of Duty: Modern Warfare 3’sfinal season is live, adding a bunch of Halloween-themed cosmetics and equipment to both Multiplayer and Warzone. Sledgehammer has added some highly experimental AMP kits as a sendoff for this game. There are only three conversion kits this season, but they are some of the game’s most creative attachments.

This week, Season 6 kicks off with the JAK Salvo, a conversion kit for the KATT AMR that transforms it into a bolt-action rocket launcher. Let’s go over how this conversion kit works, how to unlock it, and showcase all 21 challenges available in the first set of weekly challenges.

Week 1 Challenge Reward

This week’s AMP reward is theJAK Salvo Kit for the KATT-AMR, available upon completing any five of this week’s challenges. The JAK Salvo Kit converts the KATT-AMR into abolt-action rocket launcher.It works identically to the RPG-7 but has a three-round magazine and slower projectile velocity. It’s solid for damaging killstreaks and equipment, but any player with EOD Padding will shrug off this weapon.

The JAK Salvo Kit locks your barrel, muzzle, magazine, and ammunition attachment slots.
