Warzone’s ISO 45 remains a deadly SMG, so here are all of the meta attachments, Perks, and Equipment you’ll need to build the best ISO 45 loadout within the free-to-play title.

Warzone’s MW3 integration is on the horizon, and while it will bring plenty of new content and weapons to the battle royale, we still expect SMGs such as the ISO 45 to remain strong on the new Urzikstan map.

The ISO 45 is a powerful SMG, enabling players to deal consistently strong damage during close to mid-range combat. However, it’s essential to equip the weapon with the right attachments to get the most out of it.

With that said, here’s the best Warzone ISO 45 loadout, including the attachments, Perks, and Equipment you should use in Season 1 of MW3.

Best Warzone ISO 45 loadout attachments

  • Underbarrel: FSS Sharkfin 90
  • Muzzle: Spiral V3.5 Flash Hider
  • Magazine: 45-Round Drum
  • Ammunition: .45 Auto Hollowpoint
  • Stock: Demo Fade Tac

Kicking off this best Warzone ISO 45 loadout, we’ve gone for the Spiral V3.5 Flash Hider Muzzle in order to improve the weapon’s recoil, allowing you to hit more shots, especially at mid-range.

The FSS Sharkfin 90 Underbarrel will help you improve the ADS speed and aim walking speed to give you a mobility boost, highly needed for SMGs to get the most out of them.

The Demo Fade Tac Stock will help greatly with mobility, improving sprint speed, stability, and sprint-to-fire speeds. This is vital at close range, as landing the first shot can be the difference between life and death.

Lastly, the 45 Round Drum with .45 Auto Hollowpoint Ammunition is an essential combination for Warzone, as you’ll need to keep the pressure on with as many bullets as possible before reloading.

Best Warzone ISO 45 loadout Perks and Equipment

  • Base Perk 1: Overkill
  • Base Perk 2: Double Time
  • Bonus Perk: Fast Hands
  • Ultimate Perk: Ghost
  • Tactical Equipment: Frag Grenade
  • Lethal Equipment: Flash Grenade

As for Perks, we feel Overkill is essential with the ISO 45, as you’ll need a long-range secondary to deal with engagements outside of the ISO 45’s capabilities. Double Time is a great pick for any Warzone SMG, as it keeps you light on your feet.

Fast Hands will ensure you can reload fast to stay in the fight and switch your weapon quickly to react in situations where you may need to pull out your secondary. Lastly, Ghost is great for keeping your location hidden, allowing you to move more freely.

Equipment is also an important part of your loadout, and we’ve gone with the Frag Grenade and Flash Grenade, as these are great tools for putting pressure on enemies and initiating a push.
