Best ISO 45 Warzone 2 loadout: Attachments, class & perks

The ISO 45 SMG arrived in Warzone 2 Season 4 and it had a huge impact on the meta, becoming one of the most popular weapons in the game. While nerfs in the Season 4 Reloaded patch attempted to temper the SMG's power, it remains a top-tier pick in Season 5 with a 9.8% overall pick rate.

Custom-built for aggressive pushes and putting pressure on foes, the ISO 45 is a high-fire-rate submachine gun with a lightweight design.

Despite having plenty of firepower, the ISO 45 needs a meta WZ2 loadout to truly push its strength to the limit.

Luckily, we've got you covered with the best Warzone 2 attachments for the ISO 45 in the current meta so you can dominate your foes with the gun.

For starters, kick off the ISO 45 build with the Demo Fade Tac stock, this will significantly improve your mobility with added aim walking and sprint speed.

Next, make sure to equip the A30 Stout rear grip and 7" EX Raptor V2 barrel, these will drastically enhance your ADS time, hip fire control, and of course, push the gun's firepower to the limit.

Following this, attach the Spiral V3.5 Flash Hider muzzle for a boost of recoil control so you're guaranteed to land your shots on target.

Round off the loadout with the 45-Round Drum to ensure you've always got plenty of ammo and can take out multiple enemies without having to waste time reloading.

Best ISO 45 Warzone 2 class: Equipment & perks

Perks

• Perk 1: Overkill
• Perk 2: Bomb Squad
• Bonus Perk: Fast Hands
• Ultimate Perk: Ghost

Equipment

• Lethal: Grenade
• Tactical: Stun Grenade

As the ISO 45 is built for close to mid-range engagements, Overkill is a must-use perk, as it gives you access to a second primary. You can choose any weapon you'd like, but it's key it can perform at long-range, so we recommend a meta AR like the ISO Hemlock or M4.

Next, run Bomb Squad to give you a huge amount of protection from killstreaks and Fast Hands so you can quickly switch to your AR.

In terms of your Ultimate perk, Ghost is always a solid meta choice as it keeps you off opponents' radars and UAVs.

Finally, finish off the class with a Stun Grenade to throw out before a push and a Grenade for forcing enemies out of cover.
