The best Warzone ISO loadout

Our best setup for the latest Modern Warfare and Warzone SMG

Best Warzone ISO loadout

Looking for the best ISO loadout in Warzone? This SMG appears to behave quite similarly to the Fennec: its rate of fire is very high, but its damage and accuracy make it hard to land all of those shots. However, it’s a much more tempered version of the Fennec, with a slightly lower rate of fire and much better handling stats. The changes made in Warzone mid-season update targeted the attachments for SMGs, making weapons like the underutilised ISO worth using.

So, what does our best Warzone ISO loadout do to improve upon the base weapon? The ISO is weak when it comes to all of the key characteristics that make a good Warzone weapon. It’s magazine size is small and it appears to have a lot of damage drop-off over long range. Our list of attachments fixes a lot of the problems in these key areas, creating a significantly improved ISO all round.

Of course as a Warzone SMG you still want it to handle well and be mobile, so we’ve made sure to balance the various requirements in the build below.

Best Warzone ISO loadout

The best Warzone ISO loadout is:

  • FSS Nightshade
  • FTAC Vagrant
  • ISO Tac-Form
  • 50 Round Drums
  • Merc Foregrip

Like the Fennec, the ISO can also be equipped with an integral suppressor, which effectively saves you one attachment slot. The FSS Nightshade assists recoil control, extends your range, suppresses the weapon, and ups your bullet velocity.

We’ve also gone for the FTAC Vagrant which slightly increases your aim down sight speed with a minor penalty to aiming stability. Next, we’ve taken the ISO Tac-Form and Merc Foregrip to add as much recoil control as possible, and finally we’ve extended the magazine size to the maximum of 50 rounds using the 50 Round Drums. If you want a little more aim down sight speed then we suggest swapping the ISO Tac-Form out for the FTAC Elite ISO Grip.

As for the rest of the build, we suggest pairing the ISO with our best Warzone Krig 6 loadout so you have a weapon that’s capable of handling mid to long range. That means you’ll have to save your second perk for Overkill. Your first perk should be EOD so you can tank a lot more explosive damage, while your third perk should be Amped so you can switch between the ISO and Krig 6 much faster.

We’re getting tired of recommending it, but you really can’t go wrong with the combination of C4 and Heartbeat Sensor to round out this build. If you’re running this as your extremely close-quarters weapon then we suggest trying out our best Warzone MP5 setup, or even the MP7 – the ISO just can’t match these two for clearing out rooms.
