Modern Warfare 3 Season 2: The JAK Limb Ripper Guide and Weekly Challenges for 2026
Unlock the brutal JAK Limb Ripper underbarrel chainsaw attachment in Call of Duty: Modern Warfare 3's latest season, a devastating close-quarters tool that transforms your rifle into a melee powerhouse. Earn this hilariously satisfying reward by completing just five of this week's varied multiplayer, Zombies, and Warzone challenges.
The second season of Call of Duty: Modern Warfare 3 for 2026 has dropped another wild piece of gear for players to chase, and it's a real beaut. This week, the prize is the JAK Limb Ripper, an underbarrel attachment that's less of a tactical tool and more of a statement piece—a statement that says, "I like my eliminations up close and personal, with a side of motor oil." This little beauty turns your standard-issue rifle into a portable lumberjack's nightmare, complete with a whirring chainsaw blade ready to make confetti out of any opponent foolish enough to get within hugging distance. While it won't be winning any long-range sniper duels, it's a hilariously satisfying reward for those willing to complete just five of this week's varied challenges across Multiplayer, Zombies, and Warzone. Think of it as the game's way of saying, "Here, have some fun for a change."

Now, let's talk about this week's star, the JAK Limb Ripper. This isn't your average underbarrel grenade launcher; it's a personality transplant for your gun. Once installed on most rifles, your standard melee attack gets a serious upgrade. Instead of a polite gun-butt to the face, you deliver a revved chainsaw straight to the torso, which, as you might imagine, is a one-hit ticket back to the lobby for your target. Just remember, this thing has the lunge distance of a sleepy sloth, so you gotta be right up in their business for it to work.
But wait, there's more! By pressing the underbarrel key (left on the D-pad for console warriors, 'B' for the PC master race), you can actually wield the chainsaw like a proper maniac. Holding down fire will spin up the blade and let you carve through enemies. In core Multiplayer, it takes a couple of swipes, making it slower than the instant-kill melee jab. However, in the zombie-infested chaos of MWZ, especially if you've given your weapon the ol' Pack-A-Punch treatment, this mode turns into a veritable lawnmower of undead destruction. It's a DPS monster waiting to happen.
Alright, let's break down how to earn this beauty. You only need five challenges total, so mix and match from the playlists you enjoy most.

A quick pro-tip for all you cache hunters: those green boxes hum a little tune when you're close. Seriously, turn up your audio and listen for it—it's like a treasure hunt with a soundtrack. And if you're really struggling to find enough, the chaotic, respawn-friendly Plunder mode is basically a loot cache paradise. Just saying.
