Welcome back, zombie slayers! If you're diving into Call of Duty: Black Ops 6 Zombies in Season 3, you already know we're in the middle of one of the best updates yet. From killer new weapons to a thrilling new map—Shattered Veil—there's a ton of new content to explore, especially for high-round grinders and boss hunters.
In today’s article, we’re breaking down the top 5 best weapons to use in BO6 Zombies Season 3, especially for taking on those tough main quests and the Z-Rex boss fight. This isn’t an official tier list—but if it was, we’re confident this would be pretty damn close.
Let’s jump right into it!
1 – GS45 Dual Pistols (Explosive Power Reborn)
These fan-favorite explosive pistols are back on top in Season 3, and if you're playing Shattered Veil, they’re available right from the spawn room. Unlike previous DLC maps like Citadel and Tomb, this time there’s no explosive immunity for bosses—and there's a PhD machine on the map. That means you can finally go all in with explosive damage without the splashback ruining your day.
Great for: High-round farming, main quests, and boss fights
Easily deals 8,000+ damage to Z-Rex’s critical zones
Works perfectly with the Ray Gun Mark II for a deadly loadout combo
Doesn’t require precise aim—splash damage handles the rest
Loadout Tip: Equip Speed Cola and PhD early, and you’ll breeze through waves.
2 – AAX Assault Rifle (Underrated Meta)
The AAX is easily one of the most underrated ARs in BO6 right now. It has quickly become a fan favorite with strong recoil control, high damage, and solid performance against both regular zombies and elite enemies.
Whether you're doing Easter eggs or just trying to hit round 50, this gun shreds through everything. Bonus: It’s surprisingly effective against Z-Rex when paired with the Ray Gun Mark II.
Great for: Mid-to-high round runs and elite enemy takedowns
Drum mag = consistent DPS | 10-round mag = high burst damage
Versatile: Good recoil control even without heavy attachments
Slightly weaker than GS45s, but way more flexible
3 – Nail Gun (The Surprise Meta Weapon)
This new addition in Season 3 came out of nowhere and quickly bumped the Siren 9mm off our list. It starts off slow, but once you Pack-a-Punch and add Double Tap, the Nail Gun becomes an absolute monster.
Before PaP: Only 15 nails per mag – tough early-game
After PaP: 100-round mag with surprising DPS and smooth handling
Feels like a better Siren 9mm: More ammo, similar mobility
Great synergy with the Ray Gun Mk II in boss fights
Pro Tip: Use this to quickly clear out tight hallways and chip away at elite enemies while staying fast on your feet.
4 – Kilo Assault Rifle (Smooth, Fast, Reliable)
Another Season 3 DLC weapon that delivers in BO6 Zombies is the Kilo AR. While it doesn’t have a unique Pack-a-Punch effect, its fire rate and recoil control make it a dream to use—especially on mouse and keyboard.
High RPM with easy recoil = effortless zombie mowing
Perfect for casual players and solo runs
Weak vs Z-Rex – better for general survival and objectives
Dominates in rounds 1–30 and decent into late-game with Double Tap
Loadout Tip: Swap in a larger extended mag for more sustained pressure.
5 – AMR Mod 4 Sniper Rifle (Boss-Melting Monster)
The AMR Mod 4 is a high-powered sniper that deals insane single-shot damage, especially against bosses like the Z-Rex. While it's not ideal for horde control, if you're going into a boss arena, this is one of the most powerful bullet weapons available.
Up to 8,000 damage per critical shot
Downside: Low mag size + finger fatigue from spamming
Best used as a secondary to the Ray Gun Mk II
Great for players who can keep steady under pressure
If you're looking for the easiest setup, the GS45s with PhD and the Ray Gun Mark II are like flipping the game into “easy mode.” For those who prefer precision and variety, the AAX and Nail Gun give you flexible tools for any type of run—high rounds, boss fights, or casual quests.
And don’t sleep on the Kilo or AMR—they shine in the right situations.
