Modern Warfare 3's Week 3 Challenge: Unlocking the JAK Maglift Kit for the Haymaker
xxx
The digital battlefield of 2026 hums with renewed purpose as Call of Duty: Modern Warfare 3 unveils its third set of Weekly Challenges for Season 2. The prize? The much-whispered-about JAK Maglift Kit for the Haymaker shotgun, a piece of aftermarket tech that promises to rewrite close-quarters engagements. Just like that, the grind feels fresh again. Players need only complete any five challenges from this eclectic weekly menu—spanning Multiplayer, the haunting corridors of MWZ, and the sprawling danger of Warzone—to claim their reward. The kit will wait patiently all season long, but for those who hear the siren call of rapid-fire carnage, the time to act is now.
The Week 3 Prize: JAK Maglift Kit
Completing five challenges this week grants access to the JAK Maglift Kit for the Haymaker. This isn't just a new coat of paint; it's a mechanical heart transplant. The kit installs a hefty 60-round drum magazine and a new receiver that effectively doubles the weapon's fire rate. The real party piece, though, is the binary trigger. It's a chatty little mechanism, firing a shell both when you press and when you release the trigger, mirroring the behavior of the COR-45's conversion kit. Talk about a lead-spewing conversation!
However, this newfound speed comes with a solemn pact. The JAK Maglift Kit downscales the Haymaker's ammunition to .410 gauge, slashing its damage output by a whopping 42%. Its minimum damage range also takes an 18% hit, meaning your shots will lose their bite much quicker over distance. It's a classic high-risk, high-reward setup. The silver lining? The barrel and muzzle slots remain free, offering a chance to bandage these wounds with the right attachments.
Multiplayer Mayhem
The core multiplayer arena offers a smorgasbord of challenges that'll have you switching up your playstyle on the fly. Here’s the breakdown:
| Challenge | XP Reward |
|---|---|
| Get 30 kills with a Haymaker using no attachments. | 1,000 XP |
| Get 2 kills in one magazine 10 times with a recommended LMG. | 5,000 XP |
| Get 20 hipfire kills with recommended pistols. | 5,000 XP |
| Get 2 kills in one magazine 20 times with a recommended marksman rifle. | 5,000 XP |
| Get 10 point blank kills with recommended shotguns. | 7,500 XP |
| Get 7 longshot kills with recommended shotguns. | 7,500 XP |
| Get 5 triple kills with recommended shotguns. | 10,000 XP |
A few pro-tips for the grind:
-
"Barebones" means exactly that—a naked gun with zero attachments. So, for that first challenge, just grab a stock Haymaker and go to town.
-
Look for the little flame icon next to weapon names in your create-a-class menu; that's your "recommended" tag.
-
For the "kills in one mag" tasks, slap on the biggest magazine you can find. Give yourself some breathing room, you know?
-
A shotgun kill within five meters counts as point-blank. Get up close and personal.
-
If you're chasing multi-kills, the chaotic, close-quarters maps like Rust, Shipment, Meat, and Stash House are your best friends.
Zombies (MWZ) Nightmare
The undead hordes of Urzikstan present a different kind of test, one of endurance and precision against the shambling masses.
| Challenge | XP Reward |
|---|---|
| Get 250 critical kills with recommended shotguns. | 2,500 XP |
| Get 150 kills with a recommended shotgun at legendary (orange) rarity. | 5,000 XP |
| Get 100 critical mercenary kills with a recommended marksman rifle. | 5,000 XP |
| Get 300 kills in full-auto fire with a recommended weapon. | 5,000 XP |
| Get 10 kills without being hit 20 times with a recommended shotgun. | 7,500 XP |
| Get 50 mercenary kills with a recommended pistol. | 7,500 XP |
| Get 25 Hellhound kills with the Haymaker. | 10,000 XP |
Surviving the tips:
-
For the shotgun challenges, the Lockwood 680 is a community favorite. Pack-A-Punch it with Slug Ammo for a serious damage boost. It's a game-changer.
-
Remember, most MW2-era battle rifles have a full-auto toggle if you need it for that 300-kill challenge.
-
Those fiery Hellhounds love the High Threat zone. If you're hunting them, that's where you'll want to be.
-
The "10 kills without being hit" challenge requires patience and positioning. Let the zombies come to you in a choke point.
Warzone's Grand Stage
In the vast, player-infested lands of Warzone, challenges shift from pure aggression to tactical map control and survival.
| Challenge | XP Reward |
|---|---|
| Open 50 loot caches. | 2,500 XP |
| In Urzikstan, get 10 operator kills in the northwest region (Resort, Power, Seaport, Cargo). | 5,000 XP |
| In Urzikstan, get 10 operator kills in the southern region (City, Suburbs, Manor). | 5,000 XP |
| Complete 15 contracts in Warzone. | 5,000 XP |
| In Urzikstan, get 10 operator kills in the eastern region (Military Base or Farms). | 7,500 XP |
| In Urzikstan, get 10 operator kills in the central region (Old Town, Low Town). | 7,500 XP |
| In Warzone, place in the top ten 5 times. | 10,000 XP |
Battle Royale strategies:
-
The regional kill challenges are a great excuse to drop hot and learn the intricacies of each named location. It’s about owning your turf.
-
Contracts are your best friend for the "complete 15" task. They give cash, loot, and objective—killing three birds with one stone.
-
For the top-ten placements, sometimes the best weapon is discretion. Play the circle, rotate early, and let other teams thin each other out. It’s a valid strategy, no shame in it!
As the season progresses, this weekly offering stands as a testament to Modern Warfare 3's evolving ecosystem. The JAK Maglift Kit waits, a symbol of transformed potential, for those willing to master its violent rhythm across every mode the game has to offer. The challenges are set. The reward is tangible. The rest, as they say, is up to you.
