The Shattered Veil boss fight in Call of Duty: Black Ops 6 is considered by many players to be one of the hardest encounters in the entire game—especially its chaotic final phase. But what if we told you there’s a trick so broken that you can instantly shred every phase of the boss without even firing a single bullet?

In this guide, we’ll walk you through how to perform the instakill strategy step by step, including all the necessary setup, augments, perks, and timing tips. If done correctly, this method can make one of the toughest fights in Black Ops 6 Zombies an absolute joke.

The Core Strategy: Epha Shroud + Melee Combo

The secret to this method lies in a field upgrade called Epha Shroud. While it might not look powerful on paper, with the right augments and setup, it becomes a one-button boss destroyer.

Combined with a triple Pack-a-Punched melee weapon, this method allows you to deal absurd damage every time the boss enters a vulnerable phase. Let’s break it down.

Step-by-Step Setup Guide

Before you trigger the boss on round 23, there are a few key things you need to do:

1. Equip the Epha Shroud Field Upgrade

This is the heart of the strategy. Epha Shroud with the right augment deals massive damage to the boss, but we’ll go over that augment in detail later.

Pro Tip: Make sure you have two charges by equipping the Extra Charge minor augment.

2. Prepare a Triple Pack-a-Punched Melee Weapon

Yes, really.

You’ll need to choose a melee weapon and upgrade it fully. We highly recommend the Power Drill due to its speed and high damage output.

Any melee weapon can work, but it must be triple Pack-a-Punched for the damage scaling to kick in.

3. Grab GobbleGums (Optional but Recommended)

To make this method smoother, use these GobbleGums:

Raindrops – Spawns all power-ups, including Full Power

Arsenal Accelerator – Recharges your field upgrade faster

Power Keg – Instantly spawns a Full Power drop

Place a C4 in the monitor window by the Full Power location to make it easier to grab during the fight.

4. Use These Perks and Augments

Essential Perks:

Melee Makiato – Boosts your melee performance

Espresso (Major Augment) – Speeds up melee attack rate

Stick and Move – Useful for zombie control

Juggernog, Quick Revive, Stamin-Up, PhD Flopper – for survivability

How the Instakill Trick Works

Once the boss enters a puking phase, stand directly beneath him and let him launch you into the air. When you're airborne and aligned with his body:

Activate Epha Shroud mid-air

Spam the melee attack button

If done correctly, the boss's health bar melts instantly.

Repeat this for each phase of the fight. As long as your field upgrade is charged and you're positioned correctly, you'll bypass the entire challenge.

Bonus: This trick also lets you mount the boss’s body, an Easter egg few players know about!

The Key Augment: Void Sheath

This is what makes the whole thing so busted. Equip Void Sheath as your Epha Shroud augment.

Why?

It amplifies melee damage when activated

Works insanely well with tier 3 Pack-a-Punched melee weapons

Triggers absurd boss damage on the Z-Rex (the boss) when combined with good positioning

Pro Tips for Execution

Always keep one Epha Shroud charge ready for each phase

Use Power Keg between phases to recharge if needed

Time your LT53 Kazmir grenades properly (preferably when the boss jumps down for a new phase)

You don’t need to shoot a single bullet—your melee and field upgrade will do all the work

This strategy turns the Shattered Veil boss fight from a high-stakes survival test into an instakill speedrun. While the timing and positioning can be a bit tricky, with practice you'll have the easiest boss fight in Black Ops 6 Zombies history.
