How to Beat the Z-Rex Boss in Black Ops 6 Zombies Shattered

[katharineee]

If you've made it to the Z-Rex in Black Ops 6 Zombies, congratulations—you're at the climax of Shattered Veil’s Easter egg. But don’t celebrate just yet. This undead, skeletal T-Rex boss doesn’t go down easily. With four deadly phases, hordes of zombies, and one-shot kill attacks, the Z-Rex is the ultimate test for even the most experienced squads.

Prepare the Perfect Loadout
Before entering the arena, assembling the best loadout possible is absolutely critical. The Ray Gun Mark 2-W is your primary go-to here. This variant’s wraithfire ammo and full-auto mode are essential for keeping pressure on the boss while managing zombie spawns. For your secondary weapon, you can’t go wrong with dual-wielded Sally & Forth or the Wunderwaffe DG-2 for crowd control.

Your Field Upgrade should be Aether Shroud, paired with the Extra Charge augment. It allows you to slip into invisibility twice before recharging, giving you time to heal or reposition. For solo players, the Burst Dash augment adds extra escape options, while Group Shroud helps keep squads alive.

As for Scorestreaks, bring a Chopper Gunner. It can be bought at Crafting Tables for 2,500 Salvage or earned by defeating Elder Disciples. Supporting gear like Stims and Cymbal Monkeys help, though Z-Rex will ignore the latter.

To top off your kit, visit the Der Wunderfizz machine after Round 25 to grab key Perk-a-Colas like Jugger-Nog, Speed Cola, Double Tap, and Stamin-Up.

Looking to fast-track your loadout? Stock up on premium Call of Duty: Black Ops 6 Items like Scorestreaks, Perks, and crafting materials to give yourself a solid edge before the fight even begins.

Z-Rex Boss Fight Strategy
The fight has four phases:

Phase 1 – Bite & Charge: The Z-Rex will bite and lunge toward players. Focus fire on the glowing weak spot on its chest.

Phase 2 – Undead Swarm: Zombies spawn nonstop. Use Aether Shroud and AoE weapons to manage the chaos.

Phase 3 – Devour Attack: The Z-Rex tries to eat players. Keep moving and time your evasive skills.

Phase 4 – Rampage: The arena goes dark, and Z-Rex becomes enraged. Use your Chopper Gunner and GobbleGums to finish the job.

With the right gear and strategy, you’ll send the undead dino back to extinction.
