The humble Renetti has always been a decent secondary weapon, but it’s become a meta pick in Warzone Season 3. Let me show you how to build it and unlock the parts.
The best Renetti build in Warzone Season 3
The Renetti boasts a blindingly fast TTK (time-to-kill) and is so strong up close that it’s borderline unfair. Most of this power comes from the new JAK Conversion kit, which turns the burst-fire Renetti into a full-auto monster. Here’s the build:
Best Renetti attachments
You’re in for a shock if you’ve not seen this weapon in action yet. The 50 50-round drum gives us enough ammo to engage multiple targets. The Flash Hider and Rear Grip make the Renetti’s recoil a little easier to control, and the Optic is a personal preference.The JAK Conversion Kit converts the Renetti to fully automatic fire, making it powerful enough to compete with top-tier SMGs. This combination is so potent I won’t be surprised if it gets nerfed soon, so enjoy it while you can!
How to get the JAK Ferocity Carbine Kit in MW3 Warzone
If you’re a PlayStation user, you’re in luck, as you can get the JAK Ferocity Carbine Kit in an exclusive pack on the PlayStation Store.
You candownload the “Combat Pack 2 (Decomposition)” directly from the PlayStation Store(pictured above). Note that this is different from the in-game Call of Duty store.If you’re not a PlayStation user, you can unlock the Kit by leveling the Renetti up to Level 21. Once you’ve done that, you must get 30 kills with the Renetti equipped with fiveattachments. I’ve been leveling my Season 3 guns on the Emergency 24/7 Playlist in MW3. The map is small but less chaotic than Dust or Shipment and has more predictable spawns.If you don’t have Modern Warfare 3, I recommend trying your luck in Resurgence on Rebirth Island, as you can respawn in that mode.If you’re visiting Rebirth Island, verify tovisit the Biometric Scannersscattered across the map. These Scanners give you Keycards to trade at Buy Stations for unique rewards.
