You’re grinding through Liberty Falls, the neon glow of the comic shop flickering in the corner of your eye, and all you can think about is that one missing piece of the puzzle. It’s the Citadelle des Morts stamp. If you’ve been anywhere near the Black Ops 6 Zombies community lately, you know exactly what I’m talking about. It isn’t just a collectible. For a lot of players, it’s a massive headache that stands between them and the "Master Collector" calling card or that sweet sense of 100% completion.
Let’s get one thing straight. This isn't your standard "pick up a shiny object" quest. It's tied to the Skerries and the broader lore of the Dark Aether. Honestly, most people stumble onto it by accident or spend four hours watching YouTube guides only to realize they missed one tiny interaction in the church.
What the Citadelle des Morts Stamp Actually Is
Basically, it's a social and progression mechanic built into the Liberty Falls map. Think of it as a souvenir from the "Citadel of the Dead." In the context of the game's lore, the Citadelle is a reference to the haunting French fortress, and the stamp is part of the "Mr. Peaks" set of collectibles.
You find it at the Olly’s Comics location, but it isn't just sitting on a shelf waiting for you. You have to earn the right to buy it. It’s a literal physical stamp that appears in your inventory, but its value is purely for the "Skerry" set collection. If you're trying to unlock the "Master Collector" trophy, this is one of the non-negotiables.
The stamp itself costs 500 Essence. Cheap? Yeah. But the path to getting it is where people get tripped up. You need to have interacted with the crafting bench and handled the specific requirements of the "Aetherella" questline or at least progressed the map to the point where the shop's special inventory triggers.
It's weird. Some rounds it seems to be there immediately; other times, you’re round 25 and still looking at a blank counter.
Why Everyone is Hunting for It Right Now
Completionism is a hell of a drug. But there's more to it. The Citadelle des Morts stamp is a gateway. In Black Ops 6, Treyarch leaned heavily into these "Easter Egg Lite" mechanics. They aren't the main quest—they won't end the game or trigger a massive boss fight—but they provide the depth that veteran players crave.

Here is the thing: the stamp is part of a larger set of five items. You need the Bowling Ball, the Aetherella Figure, the Comic Book, and the Trophy. Without that stamp, the set is incomplete. You don't get the XP boost. You don't get the calling card. You basically just have a bunch of junk in your backpack.
I've seen players ignore the main objective entirely just to loop back to the comic shop. It’s funny because, in the middle of a zombie apocalypse, we’re all worried about getting a stamp on a piece of paper. But that’s the charm of Zombies, isn't it? The absurdity of the tasks.
The Lore Connection
If you care about the story—and if you’re hunting stamps, you probably do—the Citadelle des Morts isn't just a random name. It's a nod to the classic European horror vibes Treyarch has been cultivating since the World at War days. The Citadelle represents the old world being consumed by the new Aetherial threat. By collecting the stamp, you’re essentially "logging" a location that has been tainted.
Kevin Drew and the design team at Treyarch have been vocal about making the environment "speak" to the player. The stamp is a piece of environmental storytelling. It tells you that even in a small town like Liberty Falls, the reach of the Dark Aether is global. It’s connected to places far beyond the borders of West Virginia.
How to Get the Citadelle des Morts Stamp Without Losing Your Mind
Don't overcomplicate this. Seriously.
First, you need to get to Olly’s Comics. It's on the main strip. If you’re facing the church, it’s to your left, past the motel. Once you’re inside, head to the back counter.

- Power is Priority. You aren't getting anything if the town is dark. Flip the switches. Get the vents cleared.
- The Essence Requirement. Keep 500 Essence in your pocket. Don’t spend it all on a lucky spin at the Mystery Box.
- The Interaction. Look for the small display case next to the register. If the stamp is available, you’ll see a prompt.
- Check Your Inventory. It sounds stupid, but check if you already have it. Sometimes the pickup animation is subtle, and players spend ten rounds trying to find something they already shoved in their pockets.
If it’s not appearing, it’s usually because you haven't triggered the "Skerry" dialogue. Walk around the shop. Interact with the Aetherella statue. Sometimes the game needs a little nudge to realize you’re actually doing the side quest.
Common Misconceptions and Bugs
Let's talk about the "glitch" everyone keeps posting about on Reddit.
Sometimes, the Citadelle des Morts stamp simply doesn't spawn. You’re at the counter, you have the money, the power is on, and... nothing. In most cases, this isn't a bug. It’s a round-based trigger. I’ve found that it consistently shows up after Round 10. If you’re rushing the shop on Round 2, you’re going to be disappointed.
Another thing? You can't get it if someone else in your squad already picked it up and didn't tell you. In public matches, this is a nightmare. The items in the comic shop are often "first come, first served" for that specific instance of the item. If you’re playing with randoms, sprint to the shop as soon as the doors are open.
There’s also a theory floating around that you need to be playing as a specific character like Weaver or Maya to get certain items. That’s nonsense. Any operator can pick up the stamp. Don't let the forums confuse you with "secret character requirements" that don't exist.
The Payoff: Is it Worth the Effort?
Honestly? If you’re just playing for high rounds, no. A stamp won’t help you kill a Mangler faster. It won’t give your Mustang and Sally more ammo.

But for the "Master Collector" grind, it’s essential. That calling card is one of the rarest in the early lifecycle of Black Ops 6. It shows you know the maps inside out. It shows you didn't just sit in a corner with a Sentinal Turret; you actually explored.
Plus, there is a small Essence bonus when you complete the full set in a single match. It’s not enough to buy a Perk-a-Cola, but it’s a nice little "good job" from the developers.
Strategies for Efficiency
If you want to get this done fast, run a solo match.
- Use the Melee Macchiato perk early to save on ammo and build Essence quickly.
- Open the route to the comic shop by Round 4.
- Check the counter every round after that.
Doing this in solo removes the variable of teammates "stealing" your loot or escalating the round count before you’re ready. It's a clean, surgical way to tick that box on your achievement list.
Real Talk: The State of Zombies Collectibles
We have to acknowledge that some players hate this stuff. They think Zombies should be about shooting, not "shopping" for stamps. And I get that. But the Citadelle des Morts stamp represents a shift in how Call of Duty handles its secrets. It’s moving away from the "impossible to solve without a guide" puzzles of Revelations and toward a more "treasure hunt" style of gameplay.
It’s accessible. It’s tangible. And frankly, it makes the world feel a bit more alive—even if everything in it is technically dead.
Actionable Steps for Your Next Run
To ensure you actually walk away with the stamp and the associated rewards, follow this specific sequence during your next Liberty Falls session:
- Verify Your Collection: Before starting, check your "Challenges" tab under Zombies to see exactly which items in the Liberty Falls set you are missing. There is no point in hunting the stamp if you actually need the Bowling Ball.
- Priority Pathing: Aim to enter Olly's Comics before Round 12. The zombie density inside the shop becomes a nightmare in later rounds because of the tight corners and lack of exit points.
- The Set Synergy: If you find the stamp, immediately look for the Aetherella figure in the same building. They are often grouped in the same "logical" area of the map’s code.
- Save the Game State: If you are playing on a platform that allows "Save and Quit" in solo (like the new BO6 feature), use it once you have the stamp. This ensures that even if your internet cuts out, the collection is logged to your account profile.
Completing the collection isn't just about the digital reward; it's about mastering the map layout. Once you've done it, you'll never look at the comic shop the same way again. It transforms from a death trap into a milestone. Go get that stamp and finish the set.
