Best ISO Warzone loadout
Let’s jump right into this guide with an explanation of the very best ISO Warzone loadout we’ve found so far:
Barrel: FSS Nightshade Underbarrel: Merc Foregrip Ammunition: 50 Round Mags Laser: Tac Laser Perk: Sleight of Hand Rear Grip: No change Stock: No changes Optic: No changes Muzzle: No changes
Here you can see what the ISO looks like with this loadout equipped:
The focus of this loadout is to leverage the main selling points of the ISO. This is pretty tricky, because as things currently stand, the gun is a little bit worse than the major SMGs in almost every way. But there are two interesting points about the ISO which we’re taking advantage of in this loadout: the integrated suppressor (the FSS Nightshade), and the extremely fast reload speed. The Nightshade barrel is actually very good on the ISO, increasing the gun’s effective range by almost 50%, and quite significantly tightening up the recoil, as you can see from the below comparison:
But the other great thing about the Nightshade is that it acts as both barrel and suppressor, freeing up an attachment slot for us to pick up the Sleight of Hand perk. With SoH, the ISO’s reload speed drops to a scant 0.78 seconds, making it the fastest reload time of any primary weapon in Warzone. I’ve surprised and beaten more than a few enemies in Warzone with this extraordinary reload speed. Then we’ve added the Merc Foregrip, our favourite underbarrel for SMGs thanks to its surprising handling benefits and further recoil control; and then the Tac Laser, to compensate for the loss in ADS speed brought on by the Nightshade and Merc Foregrip. And finally, the magazine. 20 rounds is simply not good enough in Warzone, so we’ll absolutely need either the 30 Round Mags or the 50 Round Drums. Before the latest patch, the 50 Round Mags was far too slowing to use, but now it’s perfectly tolerable - and the higher your mag size in Warzone, the better. And there you have it: a powerful SMG with a decent magazine capacity, very controllable spray pattern, and unbelievably quick reload time. Take it for a spin in a Warzone match and see how you fare. Hopefully now you’ve a solid grasp of the ISO and how to make it as powerful as it can be with the right loadout in Warzone.
