What Are Stamps in Black Ops 6 Zombies?

In the Citadelle des Morts map, Stamps are key items that trigger the Sword Easter Egg. They’re dropped by a special enemy that spawns periodically and cannot be taken out with headshots. The Stamps themselves resemble rubber stamps, which likely explains the name.

How Do You Get Stamps?

  1. Progress to round 10 in Citadelle des Morts.
  2. Look for a Knight Zombie (an enemy wearing a helmet).
  3. Kill the Knight Zombie to get a Stamp as a reward.

To obtain a Stamp, you must kill a Knight Zombie. These enemies are easily recognizable by the unique knight's helmet they wear. The first Knight Zombie spawns after round ten, with more appearing in subsequent rounds. While Knight Zombies drop Stamps upon death, their heads are protected, so you’ll need to target their bodies to take them down.

What Should You Do with Stamps?

To use a Stamp, place it on any of the four Knight Statues in the Dining Hall. This will activate the statue, giving you its Bastard Sword. You can then upgrade this basic sword to unlock one of the Elemental Swords in Black Ops 6 Zombies.

Stamps are not exclusive and can be used in any order. However, it's recommended to start with the Caliburn (Fire Sword), as it is slightly easier to unlock than the others.

The Dining Hall is located in the northern part of the map and features a symmetrical layout with four Knight statues positioned in each corner.

Can You Use Excess Stamps on Anything Else?

Stamps are solely used to complete the Sword Easter Egg. Even after unlocking all four Wonder Weapon Swords, Stamps continue to spawn but currently appear to have no additional purpose. While some players speculate they might be tied to other Easter Eggs in Citadelle des Morts, no alternative uses have been discovered beyond activating the Knight Statues and obtaining Bastard Swords.
