The best ISO 9mm loadout in Warzone season one

Modern Warfare 3’s launch rejuvenated Warzone once more, and it also brought some Modern Warfare 2 guns back to life, like this one in our best ISO 9mm loadout in Warzone.

The third and final ISO weapon platform gun added into MW2 was the ISO 9mm. Fans of the ISO 45 or even the ISO Hemlock will be immediately familiar with this gun, which is a more mobile variant of those guns with much less range.

“Operators seeking a rapid-fire SMG to spray down enemies should look no further than the ISO 9mm,” Activision said of one of season six’s new guns. “Sweep the battlefield clean with the high fire rate, maneuverability, and exceptional steadiness of this 9mm SMG.”

These are the best attachments to use in the best loadout for the ISO 9mm in MW3 Warzone.

Best ISO 9mm loadout in Warzone

One of the many close-range options in Warzone, the ISO 9mm has a lightning-quick fire rate that shreds in close quarters, and a giant 50-round magazine that will keep you firing until the enemy squad is headed to the Gulag.

Best ISO 9mm attachments in Warzone

• Muzzle: Bruen Cubic Comp
• Laser: VLKR LZR 7MW
• Optic: Mk. 3 Reflector
• Ammunition: 9mm High Grain Rounds
• Magazine: 50 Round Drum

To me, the ISO 9mm feels a bit like a faster but weaker version of the ISO 45, which was one of the more dominant guns in Warzone for a while this year. For some players, that may be preferable because its strengths are its mobility and fire rate.

I’ve found the most success with the ISO 9mm at extremely close range, as it falters at gunfights at medium range or beyond, even against other SMGs in the game. And don’t even think about trying to deal with an AR at range.

But in close-quarters scenarios, like inside buildings on Urzikstan or on one of Warzone’s Resurgence maps, the ISO 9mm is a welcome addition. Its fire rate makes it especially adept at shredding enemy armor up close.

This set of attachments I use above helps rein in its recoil control, accuracy, and handling, meaning you’ll be able to swiftly outmaneuver enemies who push you up close. It also gets a buff to its damage and range, meaning this loadout is just better than anything you begin with.

Best ISO 9mm perks and equipment in Warzone

• Perk Package
  • Perk 1: Double Time
  • Perk 2: Tac Mask
  • Perk 3: Tempered
  • Perk 4: High Alert
• Secondary weapon: DG-56 or Pulemyot 762
• Lethal: Frag Grenade
• Tactical: Smoke Grenade

I like to throw the ISO 9mm into a loadout with a long-range gun like an LMG or AR and swap to the ISO 9mm when it’s time to haul ass across the map. Double Time and Tac Mask help keep me moving against all odds.

The age-old Warzone question of Smoke vs. Flash and Frag vs. throwing knife rings true to this day. Flash grenades are incredibly powerful, but smokes are almost a get-out-of-gulag-free card. And when it comes to lethals, your preference will ring true: Do you want to blow your enemies up or finish them off after downing them without using any additional ammo?

I prefer to blow them up. But the choice is yours, gamer.
