This weird little item seems to pop up in your inventory for no reason at all. Okay, don't worry: we've got you covered!

How to Get Stamps

Stamps aren't just lying about for you to pick up—they're actually rewards for defeating a particular enemy: Knight Zombies.

Here's how to obtain one:

1. Survive Until Round 10: These Knight Zombies don't come until you have proved your worth by surviving to Round 10.
2. Find the Knight Zombie: Look for zombies sporting shiny helmets. That is it.
3. Target the Body: Forget trying to get headshots—their helmets are unbreakable. Concentrate your fire on their bodies and they will fall.
4. Acquire the Stamp: After you take down the Knight Zombie, collect the Stamp it drops.

Knight Zombies will continue to spawn in later rounds so if you miss out on the first opportunity, don't worry you will get more chances.

What Do You Do With Stamps?

Now that you’ve got a Stamp, it’s time to use it. Head to the Dining Hall, which is located in the northern part of the map. This room features four Knight Statues, one in each corner.

How to Use Stamps:

1. Go up to a Knight Statue and interact with it to place your Stamp.
2. This will get the statue to activate and reward you with a Bastard Sword, the basic version of the Wonder Weapon Swords.

Upgrading to Elemental Swords

The Bastard Sword is cool and all, but the real prize is getting it to one of the Elemental Swords. Here are your options:

• Caliburn (Fire Sword): This is the fan favorite and easiest to unlock. Use it for burning everything to ashes.
• Durendal (Ice Sword): Slows enemies and freezes them on critical hits.
• Joyeuse (Lightning Sword): Electrocutes enemies, ideal for chain damage.
• Excalibur (Light Sword): A holy weapon that deals massive damage to bosses.

Each sword has its unique upgrade process, so choose wisely and plan accordingly.

Can You Use Extra Stamps for Something Else?

Unfortunately, no. Stamps are only used to activate the Knight Statues. Even after unlocking all four Elemental Swords, Knight Zombies will still drop Stamps, but they have no further purpose.

There are some theories among players that excess Stamps might connect to other hidden Easter Eggs in Citadelle des Morts, but so far, there is no solid evidence. For now, treat those excess Stamps as souvenirs-or just ignore them.

Sword Easter Egg

• Start with Caliburn: Upgrade is not rocket science here so a perfect choice to start with
• Save your ammo for the Knight Zombies. Knight zombies are relatively tough as other zombies and would take longer to eliminate if not sufficient power
• Co-op Tip: Each player must find and protect his assigned Knight Statue, it makes progress go a little faster.
• Search all of the Dining Hall: The balanced design makes it very easy to overlook a statue, so check everything carefully.

Conclusion

The Stamp system in Black Ops 6 Zombies may seem a little confusing at first, but after you understand how it functions, it is a satisfying means of unlocking the game's badass Elemental Swords. Expect to find Knight Zombies; stock up on ammo and look forward to carving your way through the hordes of undead with some truly cool weapons.

Who knows—if those extra Stamps actually have a certain "secret" use in future updates. Until then, happy slaying!
