Warzone: ISO SMG Loadout, Attachments, And Setup For Your Class

+ 2

In Season 5, Warzone was introduced to the ISO SMG.


An interesting weapon that didn't quite live up to the hype, but for some, it holds a special place in their heart.

Here are the best attachments and setup for the ISO in Warzone.

Primary Weapon

The ISO SMG handles similarly to the MP5. You'll want to try and stick to similar attachments as the MP5 because of this.

The attachments you'll want to use are:

  • FSS Nightshade (Barrel)
  • ISO Collapsible (Stock)
  • 50 Round Drums (Ammunition)
  • Merc Foregrip (Underbarrel)
  • Tac Laser (Laser)

One benefit you'll get from the ISO over the MP5 is the 50 round mags. Although the difference is only 5 bullets, this can make a huge difference in those clutch situations.

It'll be interesting to see whether the ISO is accepted into the meta.

Secondary Weapon

The Kar98k is considered one of the best long-range weapons right now due to the buff it recently received.

The attachments you'll want to use are:

  • Monolithic Suppressor (Muzzle)
  • Singuard Custom 27.6"
  • FTAC Sport Comb (Stock)
  • Tac Laser (Laser)
  • Variable Zoom Scope (Optic)

This setup allows you to take on enemies at long-range with high damage. However, due to the Kar's snappy sights, you can also dominate at medium range.

You can also use other weapons with the ISO, such as the Bruen, M4A1 and AN-94. As long as you have a long-range option you've got a pretty solid class.



If you're playing Warzone you'll want to bring C4. This allows you to not only clear buildings with ease, but also take out multiple vehicles during the match.

If you're planning on getting aggressive with this class, a Frag Grenade would also be a good choice, as you can easily clear rooms and small areas.



You'll want to equip the Heartbeat Sensor with this class. This allows you to clear large areas at once without the need to search every room.

This can also give you a great advantage when paired with flash grenades. You can ensure the flash will hit the player in the next room by calling out the location of the enemy to your team. 


The perks you'll want to equip are:

  • Cold Blooded (Perk 1)
  • Overkill (Perk 2)
  • Tracker (Perk 3)

These perks allow you to clear buildings easily, without being caught out by campers. Unfortunately, you'll need Overkill with this class as you need two primary weapons.

If you choose this class, we recommend you also make another class with Ghost as the second perk, so you can move around the map without worrying about UAVs.
