How To Beat The Z-Rex Boss In Black Ops 6 Zombies?5 min read

The Z-Rex Boss in Black Ops 6 Zombies isn’t just a glorified dinosaur. It’s a juggernaut-sized problem that demands precise coordination, elite weapons, and smart use of your perks and upgrades. If you want to beat the Z-Rex Boss, here’s everything you need to know.

Before the Fight

You don’t just walk into the Z-Rex fight. You plan for it. Before you step into the Shattered Veil boss arena, you need to bring a solid loadout. Start with a Tier 3 Pack-a-Punched Ray Gun Mark 2-W. This fully automatic variant has wraithfire ammo and high damage output. For crowd control, dual-wielded GS45s or a Wunderwaffe DG-2 work great.

Equip a melee weapon too, ideally the Power Drill. Triple pack it and get ready to put it to work with an Aether Shroud trick you’ll use later. Get Juggernog, Quick Revive, Speed Cola, Stamin-Up, and Double Tap. Throw in Deadshot Daiquiri and PhD Flopper too. These perks will keep you mobile, deadly, and alive.

Loadout Breakdown

Z-Rex Phase One

The Z-Rex stomps the arena, spews gas, and tries to eat you. Avoid the gas pools and hide behind rocks. Watch its ribs. It swallows Toxic Zombies that sit inside its chest. Shoot them for massive critical hits. If it hasn’t eaten anything, aim for the glowing eyes.

At around 75% health, it jumps out. Clear zombies. Conserve ammo. Horde them and use headshots to rack up essence. Spend essence wisely at the Ammo Resupply crates.

Z-Rex Phase Two

Now things heat up. The Z-Rex will leap across the arena and attempt to crush you. You must stay mobile. Slide, sprint, and avoid green puddles. If you get stuck, use Aether Shroud to phase out and recover.

Again, shoot ribs or eyes. Use your melee sparingly unless you’re attempting the instakill strategy. When its health hits 50%, it exits again. Clear the arena of undead and stock up.

Phase Three

The third round turns aggressive. The Z-Rex charges more often and spawns more gas. Use the rocks to your advantage. Never run straight. Keep paths clear using your secondary.

This is where the Chopper Gunner can help if things feel overwhelming. Otherwise, rely on Ray Gun Mark 2-W and solid positioning. You want to avoid getting pinned. Wait for it to drop to 25%.

Final Phase

This is its rage phase. It will not stop. It bites, lunges, and tries to knock you out cold. Use Aether Shroud to dodge death. Save the Chopper Gunner for this moment. Fire directly into the glowing eyes. Keep pressure until it drops.

If you get downed, don’t rush to revive. Deal damage while crawling. Use that time to knock a few more hits into the boss. Then pop the revive.

Instakill Trick Using Aether Shroud

Now for the busted strategy. The Z-Rex Boss can be instakilled using a specific combo. Use Aether Shroud with the Void Sheath augment. You need:

• Triple Pack Power Drill (or any melee)
• Aether Shroud
• Void Sheath Augment
• Melee Makiato Perk with Espresso Major Augment
• Power Keg GobbleGum (for recharge)

Wait for the Z-Rex to puke. Stand beneath him. It will launch you into the air. The moment you go up, trigger Aether Shroud. While in mid-air, melee. The combination of Void Sheath and a charged melee hits like a truck.

You must time this perfectly. Too early or too late, and you miss the launch. If successful, you can clear a phase in seconds. Repeat the process as many times as needed.

Tips To Beat Boss Quickly

• Throw C4 at the monitor before the fight to spawn a Full Power pickup later.
• Use Power Keg when Aether Shroud runs out.
• Save Chopper Gunner for phase four.
• LT53 Kasmir grenades can delay zombies.
• Don’t waste time during transition phases. Build essence.

Final Thoughts

Beating the Z-Rex Boss isn’t about luck. It’s about understanding how the mechanics work. Use the Ray Gun Mark 2-W for traditional damage or go for the risky but effective instakill method using Aether Shroud. Once you learn the timing, the Z-Rex Boss becomes one of the easiest final bosses in Black Ops 6 Zombies.
