Best ISO 45 Warzone loadout: Class setup, attachments & perks

Warzone’s short-range meta is wide open in Season 5, but the ISO 45 outshines every other option. In order to maximize the new SMG’s potential, we’ve put together the best ISO 45 loadout in Warzone.

Season 5 weapon balance changes did a lot and a little at the same time. Nerfs to the Cronen Squall opened the door for new contenders for the game’s long-range meta. And buffs to five SMGs blew Warzone 2’s short-range meta wide open.

However, after a full week of adjusting to Season 5’s changes, the same few tried and true weapons were right back at the top of popularity rankings. The Cronen Squall, ISO 45, and Lachmann Sub all comfortably held onto their spots as top meta weapons.

With the ISO 45 still standing out as a top-tier meta option, here is everything you need to know about the fast-fitting lightweight SMG.

Best ISO 45 Warzone loadout

attachments

• Muzzle: Spiral V3.5 Flash Hider (-0.77, +0.28)
• Laser: VLK LZR 7MW (-0.40, -39.48)
• Stock: SK-3 Cheetah (-2.84, -1.70)
• Rear Grip: EXP Shear (+0.73, -0.24)
• Magazine: 45 Round Drum

The ISO 45 is a throwback to the ISO SMG from MW 2019. Infinity Ward confirmed the new SMG performs very closely to its original version, stating “its high-caliber rounds make it a heavy hitter compared to its fast-firing counterparts.”

With that in mind, our loadout focuses on finding the perfect balance between mobility and recoil control. With these attachments, dominating short to mid-range engagements should be easy.

Best ISO 45 Warzone class: Perks & equipment

• Base Perk 1: Double Time
• Base Perk 2: Overkill
• Bonus Perk: Resupply
• Ultimate Perk: High Alert
• Lethal: Throwing knife
• Tactical Equipment: Smoke grenade

Double Time makes it easier to traverse freely, improving the duration of your tactical sprint. Within nine meters the ISO 45 shreds through enemies, but anything further and you may be in trouble. We recommend using Overkill to pair the SMG with a meta long-range weapon such as the TAQ V or Cronen Squall.

Resupply will come in handy over the duration of a long Warzone 2 match, as you start with an additional Lethal and equipment recharges over 30 seconds. Finally, High Alert may save your life on one or two occasions, as vision pulses alert you when an enemy spots you.

To round off the setup, we recommend using throwing knives to finish off downed enemies or take down multiple enemies at once without wasting ammo. And finally, smoke grenades are great for fleeing a gunfight or rotating in the final few circles.

How to unlock the ISO 45 in Warzone 2

There are no challenges required to unlock the ISO 45. The only way to procure this high fire rate SMG is to unlock it via the Modern Warfare 2 and Warzone 2 Season 4 Battle Pass.

If you’re wanting to plot out your path accordingly to acquire the weapon quicker, the ISO Hemlock can be found in Sector D19 and is a free unlock for all players.

Best ISO 45 alternatives in Warzone 2

The biggest pitfall of the ISO 45 is its range. According to sym.gg, ISO 45 has the best time to kill among SMGS within nine meters. Anything past that range and other short-range meta options emerge as better choices. We recommend using the VEL 46 as an alternative because it offers more consistency.
