Let's be real for a second. If you’re hunting for the Armed to the Teeth BO6 achievement, you’ve probably already spent a frustrating amount of time staring at a weapon wheel that just won’t cooperate. It sounds simple on paper. Just have three different weapon classes equipped at once. But in the heat of a Black Ops 6 Zombies match, when the Manglers are charging and you're low on Essence, it’s surprisingly easy to mess this up.
Most people think this is just a lucky break. It isn't.
Winning this trophy—or achievement, depending on your platform—requires a specific sequence of events that the game doesn't exactly hold your hand through. You can't just pick up three random guns and call it a day. There is a mechanical logic to how the game tracks "classes," and if you don't respect that logic, you'll finish Round 30 with nothing to show for it but a sore thumb.
What Armed to the Teeth BO6 Actually Asks of You
The core requirement is straightforward: have three different weapon classes equipped at the same time.
In the world of Black Ops 6, weapon classes are categories like Assault Rifles, SMGs, Shotguns, LMGs, Sniper Rifles, and Pistols. However, the game starts you with only two weapon slots. You're basically a walking holster until you find a way to carry that third piece of hardware. This is where the Melee category often trips people up. Does a knife count? Technically, no, not for the slot requirement. You need a third primary/secondary firearm slot.
To even begin this process, you need the Mule Kick Perk-a-Cola. Without it, the achievement is impossible. Mule Kick is the legendary "third gun" perk that has been a staple of Treyarch Zombies for years. In BO6, it functions largely the same, but the economy of the game makes getting it a bit of a mid-game goal rather than something you grab on Round 2.
The Mule Kick Factor
You can find the Mule Kick machine on both launch maps, Liberty Falls and Terminus. On Liberty Falls, it’s tucked away near the bowling alley area, whereas on Terminus, you’ll find it deeper in the facility.
Once you drink that green soda, your HUD changes. You now have a third slot. But here is the kicker: you can't just buy three versions of the same gun. If you have three Assault Rifles, you aren't "Armed to the Teeth." You're just a guy who really likes 5.56 ammo.

The game checks for variety. You want a diverse portfolio. Think of it like a lethal investment strategy.
Why Your Loadout Matters
Most players start with a dedicated loadout weapon. Usually, this is an Assault Rifle or an SMG like the C9. That’s Slot 1.
For Slot 2, you might hit the Mystery Box or buy a wall-buy. A Shotgun is usually the play here because the Marine SP is absolutely devastating in close quarters during the early rounds.
Slot 3 is where it gets interesting. Once you have Mule Kick, you need that third distinct class. A Pistol or a Sniper Rifle works, but if you want to be efficient, grabbing a Wonder Weapon like the Beamsmasher (on Terminus) or the Jet Gun (on Liberty Falls) often counts as its own unique category.
A Step-by-Step Path to Success
- Start with an Assault Rifle. Use something reliable like the AMES 85. It’s versatile. It gets you through the early rounds without burning through all your salvage.
- Save your Essence. Don't spend everything on Pack-a-Punch right away. You need 2,500 for the Perk.
- Locate Mule Kick. Head to the machine. Drink up.
- Diversify. If you have an AR, go find an SMG or a Shotgun. Buy it off the wall.
- The Third Wheel. Hit the Mystery Box. You are looking for an LMG, a Sniper, or a Pistol.
Honestly? The easiest way to do this is to keep your starting AR, buy the Marine SP Shotgun off the wall, and then grab a GS45 Pistol. Three classes. One achievement. Done.
Common Mistakes That Kill the Run
I've seen people get frustrated because they think they have three classes, but they actually have a "blueprint" version of a gun they already own. That doesn't work.
Also, be careful with the Wonder Weapons. While they are powerful, some players have reported that the achievement didn't "pop" until they had three standard ballistic weapon classes. To be safe, I always recommend sticking to the basic categories: AR, SMG, and Shotgun. It’s the cleanest way to ensure the game’s tracking system registers the completion.

Another thing: Don't bleed out. In BO6, if you go down and lose your perks, you lose that third weapon slot. If you lose the slot, you lose the weapon. If you lose the weapon, you aren't armed to the teeth anymore. You're just armed to the gums. If you get revived and rebuy Mule Kick, you have to find a new third weapon. It doesn't just magically reappear in your hands.
The Terminus Strategy vs. Liberty Falls
Liberty Falls is generally "easier" for this because the map is tighter and the wall-buys are more obvious. You can stay in the starting area, rack up points, and move to the church and the bowling alley quickly.
Terminus is a bit more of a journey. You have to turn on the power, navigate the sea, and deal with more verticality. However, Terminus gives you more opportunities for high-tier loot early on if you're doing the side eggs.
If you're just going for the achievement and nothing else, go to Liberty Falls. It's faster. It's less stressful. You can probably get this done by Round 10 if you're efficient with your point spending.
Is it Worth Using the Mystery Box?
The Box is a gamble. Sometimes it gives you a Ray Gun on the first spin; usually, it gives you a green-tier pistol that makes you want to uninstall.
For Armed to the Teeth BO6, the Mystery Box is actually your friend because it’s the fastest way to see a variety of classes. If you have an AR and a Shotgun, literally anything the box spits out that isn't one of those two will finish the requirement for you.
Just remember that in BO6 Zombies, the rarity of the gun (Green, Blue, Purple, Gold) doesn't matter for this specific achievement. You just need the class variety. A gray-tier Pistol is worth just as much as a Legendary Sniper for the sake of this trophy.

Handling the Inventory Shuffle
Managing three weapons can be a bit of a headache. In the heat of a high-round swarm, cycling through your guns to find the right one is a skill in itself.
- Keybinds/Buttons: Get used to double-tapping your switch weapon button.
- Ammo Economy: The beauty of having three different classes is that they use different ammo pools. If your AR is dry, your Shotgun probably isn't.
- Mule Kick Tier Upgrades: If you've been playing enough to have some Augments unlocked, make sure you look at your Mule Kick upgrades. Some tiers allow you to recover your third weapon more easily or give you more ammo drops.
The Specific "Armed to the Teeth" Logic
Keep in mind that the game checks for "active" status. You must have all three weapons physically on your person. If you swap one out for a gadget or a temporary pickup (though those are rare in this context), it might flicker.
Once you have the third weapon in your hands, the achievement usually pops within 2-3 seconds. If it doesn't, try firing a shot from each gun. Sometimes the game needs a "ping" to realize you're actually holding the hardware.
Practical Steps to Take Now
To wrap this up and get you that notification on your screen, here is exactly what you should do in your next match:
- Load into Liberty Falls with any Assault Rifle you're comfortable with.
- Farm Essence until you have about 5,000. This covers doors and your first perk.
- Buy the Marine SP off the wall (it’s usually near the starting area or the first few doors).
- Beeline for the Mule Kick machine. It’s near the bowling alley. Drink it.
- Grab a third gun. The easiest is the SWAT 5.56 or a Pistol.
- Hold all three. Don't drop them, don't die, and wait for the "Achievement Unlocked" banner to slide across your screen.
If you follow that specific order, you'll bypass the confusion most players feel. It’s not about surviving to Round 50; it’s about a specific shopping list of gear. Once you have it, you can go back to focusing on the main Easter Egg or just seeing how long you can last against the horde.
Good luck out there. It's a grind, but seeing that 100% completion mark is always worth the effort.
Next Steps for Your Zombies Career:
- Check your Augments: Ensure you are researching Mule Kick tiers to make the third weapon slot less of a liability.
- Verify Wall-Buy Locations: Memorize where the LMG and Sniper wall-buys are on Terminus so you aren't relying on the Mystery Box's RNG.
- Master the Swap: Practice weapon switching under pressure; the third gun slot can actually get you killed if you fumble the buttons during a reload.
