Mastering the ISO Hemlock: The Ultimate Loadout Guide for Warzone 3

ISO Hemlock in Warzone 3

The ISO Hemlock, a fan-favorite assault rifle from Call of Duty: Warzone 2, has made its return in Warzone 3. While it may no longer be considered a top-tier meta weapon, especially with the introduction of powerful new guns like the RAM-7, the ISO Hemlock can still hold its own in the hands of a skilled operator.

In this comprehensive guide, we‘ll break down everything you need to know to create the best possible loadout for your ISO Hemlock. We‘ll cover the ideal attachments, perks, equipment, and strategies to help you maximize the gun‘s potential and secure victories across all modes of Warzone 3.

Understanding the ISO Hemlock‘s Strengths and Weaknesses

Before diving into the perfect loadout, it‘s crucial to understand the ISO Hemlock‘s unique characteristics. Let‘s take a closer look at its key stats:

Stat Base w/ Recommended Attachments
Damage 35-25 38-28
Rate of Fire 525 RPM 525 RPM
Range 35 meters 40 meters
Recoil Control 70% 90%
Mobility 82% 76%
ADS Speed 275 ms 300 ms

As evident from the table, the ISO Hemlock excels in damage output and recoil control, especially when equipped with the right attachments. Its range and rate of fire, however, leave something to be desired when compared to current meta weapons like the RAM-7 or M13B.

According to weapon statistics provided by TrueGameData, the ISO Hemlock posts a respectable time-to-kill (TTK) of around 650ms within its optimal range. This puts it slightly ahead of other assault rifles like the Lachmann-556 and M16, but behind top performers such as the RAM-7 and BAS-B.

The ISO Hemlock‘s strengths lie in its precision and consistency at medium to long ranges. Its low recoil allows for easy tracking of moving targets, while its high damage per shot ensures quick eliminations with well-placed headshots.

However, the gun‘s slower rate of fire and average mobility can be a hindrance in close-quarters engagements. Skilled players using meta SMGs like the Fennec or fast-firing assault rifles will likely outgun the ISO Hemlock in these situations.

Building the Best ISO Hemlock Loadout

With a clear understanding of the gun‘s pros and cons, let‘s construct the optimal ISO Hemlock loadout for Warzone 3. This build focuses on enhancing the gun‘s range, bullet velocity, and accuracy to maximize its long-distance potential.


  • Muzzle: Harbinger D20 – This suppressor significantly reduces the Hemlock‘s recoil, making it easier to land consecutive shots on target.
  • Barrel: Fielder-T50 Barrel – With improved damage range and bullet velocity, this barrel transforms the ISO Hemlock into a deadly marksman rifle.
  • Optic: Corio Eagleseye 2.5x – The Corio Eagleseye provides a clean, unobstructed view of the battlefield, perfect for picking off distant enemies. It also helps mitigate visual recoil.
  • Magazine: 45 Round Mag – The larger magazine ensures you have enough ammo to take down multiple opponents without reloading, though it comes at a slight cost to mobility.
  • Underbarrel: Bruen Heavy Support Grip – This underbarrel attachment further stabilizes the ISO Hemlock, granting even greater recoil control and precision.

Best ISO Hemlock Attachments

Gotta hand it to Raven Software though–the gunsmith system introduced in Modern Warfare (2019) and expanded upon in Warzone really lets you tailor weapons to your playstyle. The interplay between attachments, their benefits, and drawbacks adds a layer of depth to customization that keeps things interesting between matches as you test different combinations.


While perks ultimately come down to personal preference and playstyle, here are some top picks that synergize well with the ISO Hemlock:

  • Double Time – Doubles your Tac Sprint duration and increases crouch move speed by 30%, perfect for aggressive flanking maneuvers.
  • Fast Hands – Speeds up weapons swaps and reloads, crucial for quickly switching to your secondary weapon in close quarters.
  • High Alert – Gives you a visual warning when enemies outside your FOV aim at you, a must-have for situational awareness.

Other viable perk options include:

  • Ghost – Conceals you from enemy UAVs and Heartbeat Sensors while moving, great for stealthy play.
  • Cold-Blooded – Renders you undetectable by AI targeting systems and thermal optics, ideal for countering killstreaks.
  • Quick Fix – Grants instant health regeneration on kill, handy for chaining eliminations in hectic firefights.


  • Lethal: Semtex – A versatile grenade that sticks to surfaces and enemies, dealing high damage over a concentrated area. Cook it before throwing for maximum impact.
  • Tactical: Smoke Grenade – Smoke grenades provide excellent concealment for reviving teammates or relocating under fire. Consider running Restock to replenish your supply.

Secondary Weapon

Pair your ISO Hemlock with a close-range weapon to shore up its weaknesses:

  • WSP Swarm – This hard-hitting SMG boasts a competitive TTK and hip-fire accuracy, perfect for clearing out buildings and tight spaces.
  • Lockwood 300 – A pump-action shotgun that can eliminate enemies in a single well-placed shot, the Lockwood excels in extreme close quarters.
  • Akimbo Renetti – Dual-wielding these high-powered pistols allows for a lightning-fast TTK within their effective range, ideal as a backup weapon.

Warzone 3 Meta Weapons

Of course, the "best" loadout is always a matter of personal feel and skill. But looking at pick rates and overall usage data, it‘s clear that meta weapons like the RAM-7 and M13B remain the go-to choices for sweatier solos and squads in Warzone.

While non-meta weapons like the ISO Hemlock can certainly hold their own, you might find yourself at a disadvantage in certain situations. It all comes down to your individual playstyle and risk tolerance. If you enjoy the challenge of using off-meta guns, more power to you!

Tips for Mastering the ISO Hemlock

To make the most of your ISO Hemlock loadout, you‘ll need to adapt your playstyle and decision-making on the battlefield. Here are some advanced tips and tricks to help you dominate with this precision-focused assault rifle:

  1. Tap fire at long range – Remember, precision is key with the ISO Hemlock. Instead of holding down the trigger at longer distances, try firing in short, controlled bursts to maintain accuracy and conserve ammo.

  2. Prioritize high-traffic areas – Exploit the ISO Hemlock‘s range advantage by positioning yourself near open sightlines and high-traffic zones. Stay near cover and be ready to punish any enemies that venture into your killzone.

  3. Play the angles – The ISO Hemlock excels at holding tight angles and catching enemies off-guard as they round corners. Anticipate common routes and chokepoints, then set up ambushes to secure quick eliminations.

  4. Use smokes for more than just revives – Smoke grenades can be powerful tools for blocking sightlines, concealing rotations, or baiting enemies into unfavorable positions. Get creative with your smoke placements to confuse and misdirect opponents.

  5. Bait and switch – If you find yourself outgunned in a direct confrontation, try baiting enemies into chasing you around cover, then quickly swapping to your secondary weapon to finish them off. The element of surprise can make all the difference.

  6. Be flexible – The beauty of Warzone 3 lies in its diverse weapon sandbox and endless tactical possibilities. Don‘t be afraid to experiment with different loadouts, attachments, and playstyles to find what works best for you. There‘s no one-size-fits-all solution!

The Future of the ISO Hemlock

Looking ahead, the long-term viability of the ISO Hemlock in Warzone 3 largely depends on factors such as weapon balancing, new gun introductions, and shifts in the overall meta.

Warzone 3 Weapon Balancing

Based on past trends, we can expect Raven Software to release regular updates that tweak the performance of individual weapons and attachments. These changes, whether buffs or nerfs, can dramatically impact a gun‘s popularity and usage rates.

For the ISO Hemlock, which already faces stiff competition from current meta weapons like the RAM-7 and BAS-B, any further nerfs to its damage range or recoil could severely limit its effectiveness. Conversely, buffs to its rate of fire, handling, or mobility would make it a much more attractive choice.

It‘s also worth considering the introduction of new weapons through upcoming seasons or content drops. As we saw with the RAM-7 in Season 1, a single gun has the potential to completely shake up the meta and redefine what constitutes a "top-tier" loadout.

Ultimately, the key to success in Warzone 3 lies not in chasing the meta but in finding a playstyle and loadout that best suit your skills and preferences. Whether you‘re a die-hard ISO Hemlock main or a meta-slaving RAM-7 sweat, what matters most is your ability to adapt, communicate, and outplay your opponents.
