Call of Duty: Black Ops 6 Zombies comes with many weapons, but choosing the right weapon can mean the difference between WIN and Loss.
Season 3 Reloaded has brought numerous changes, making some weapons more viable for boss fights.
This detailed guide breaks down the best guns to use for each boss in the game, including insights into loadouts, Double Tap augments, and in-game strategies for maximum efficiency.
1. Best Weapons for the Terminus Boss Fight
The Maelstrom Shotgun: The Undisputed Goat
Many players might instinctively select the ASG shotgun for Terminus, but the Season 3 Reloaded update changed the weapon meta entirely. Now, the Maelstrom Shotgun reigns supreme. When paired with Double Tap augments, Death Perception, and the Napalm Burst ammo mod, the Maelstrom is a force to be reckoned with.
Recommended Loadout
- Attachments in Gunsmith: Ensure maxed fire rate and reload speed.
- Augments: Double Tap and Death Perception.
- Ammo Mod: Napalm Burst.
Tactics
- Focus on the first phase by firing rapidly into Patient 13’s weak points (mouth and tentacles).
- Keep Frenzy Guard equipped for defensive moments.
- In the final phases, you’ll want to continuously pump damage, leveraging the fire rate boost from Napalm Burst.
Honorable Mentions
- DM10 Marksman Rifle: Pack-a-punched with Double Tap, the DM10 becomes a semi-auto beast, dealing 15,000 non-critical damage rapidly. While less versatile for zombies, this weapon excels against Terminus’ critical spots.
- D13 Sector: Achieving an absurd 63,000 non-crit damage, the pizza-launching D13 Sector shines as a boss killer. Skip adding mods like Explosive Discs or Ricochet Discs, as these reduce overall damage. Pair this weapon with Double Tap for unmatched firepower.
2. Liberty Falls Survival Boss Fight

Different from traditional boss battles, Liberty Falls challenges players to survive waves of enemies, elites, and specials.
The best weapon here?
The D13 Sector—its one-shot capability makes light work of Manglers, zombies, and elite Abominations.
Recommended Loadout
- Attachments: Minimal, run without additional bullet mods to maintain high damage.
- Ammo Mod: Napalm Burst.
- Augments: Double Tap to double your non-critical damage and improve fire rate.
Tactics
- As waves intensify, prioritize taking out elite specials like Manglers and Abominations first.
- Leverage Vulture Raid to replenish ammo from drops.
- Keep your distance during hectic later phases, letting the D13 effortlessly clear enemies.
3. Citadel Day Mall Boss Fight

The Citadel boss fight is one of the trickiest in Black Ops 6 Zombies. With Patient 13 growing aggressive across multiple phases, a solid loadout is crucial. While the D13 Sector is still reliable, other guns such as the Maelstrom Shotgun, Ray Gun, and AMR mod 4 Sniper are standout performers.
Best Guns
- Maelstrom Shotgun: Quick fire rate and devastating damage make this an MVP for each armor-breaking phase.
- Ray Gun: Doubled fire rate (with Double Tap) leads to 6,000 critical damage per shot. This classic weapon handles aggressive enemies with ease.
- AMR mod 4 Sniper: Sporting 12k critical damage, this sniper is ideal for players with great accuracy. Thanks to Double Tap augments focusing on non-crit damage, even missed critical shots inflict substantial damage.
Tactics
- During Phase 1, target exposed armor pieces. Use Ether Shroud field upgrades strategically during moments of overwhelming enemy numbers.
- Between phases, clear zombies to recharge your field upgrades.
- In the final phase, ensure your weapon has enough ammo and use Gobble Gums (if desired) to secure survival.
Loadout Suggestions:
- Maelstrom Shotgun: Napalm Burst ammo mod paired with Double Tap augments for added speed.
- Ray Gun: Equip Double Tap’s fire-rate enhancements; optimal when handling both armor pieces and standard zombies.
- AMR mod 4: A high-risk, high-reward choice—critical accuracy will ensure quick armor breaks and phase skips.
4. The Tomb Boss Fight
The Tomb boss presents two distinctive phases: destroying sentinel artifacts and battling elites. Previously, the ASG shotgun dominated this fight, but the Maelstrom Shotgun now edges it out as the ultimate weapon.
Maelstrom Shotgun Dominance
This shotgun matches the ASG’s damage but boasts a faster fire rate thanks to recent patches. It’s ideal for the Sentinel artifact destruction phase and elite zombie takedowns.
Recommended Loadout
- Ammo Mod: Napalm Burst.
- Augments: Double Tap for enhanced fire rate.
- Attachments in Gunsmith: Focus on reload speed for faster transitions between waves.
Tactics
- Use Frenzy Guard for consistent damage throughout phases.
- When facing elites like Amalgams, rely on the Maelstrom’s rapid fire to prevent wipe attacks.
5. Shattered Veil Boss Fight
This map introduces one of the most challenging boss fights in the game, with the Z-rex being the ultimate test of skill. The AMR mod 4 Sniper rifle emerges as the strongest weapon for this boss fight, completing phases with blinding speed.
Why the AMR mod 4?
With 24,000 critical damage and 10,000 non-critical hits, this sniper outpaces every other weapon for both boss damage and zombie clearing. Its synergy with Double Tap augments ensures consistent high damage.
Recommended Loadout
- Attachments in Gunsmith: Max out fire rate and rotating optics for readability.
- Ammo Mod: Napalm Burst.
- Augments: Double your non-critical damage and boost the fire rate using Double Tap.
Tactics
- In early phases, bait toxic zombie attacks to coax Z-rex toward crit zones. Combine Ether Shroud with spamming shots for uninterrupted damage.
- Maintain ammo by leveraging Vulture Raid and zombie drops.
- The final phase challenges players with extreme Z-rex aggression. Keep your distance and use LT53 Casemirs liberally to distract zombies.
Conclusion
I repeat, in Black Ops 6 Zombies, the right weapon choice can drastically affect your experience, especially in major boss fights.
With the variety of weapons and essential loadouts mentioned above, players are equipped to handle anything the game throws at them.
Whether it’s the high damage and efficiency of the D13 Sector or the Maelstrom Shotgun’s rapid fire rate, each weapon has its own unique advantages.
Pair these weapons with the appropriate augments and perks, and you’ll find yourself dominating every boss fight with ease.
