Unlike in Liberty Falls, the Pack-a-Punch machine is not physically available when you start a match in the new Black Ops 6 Zombies map Citadelle des Morts.
You need to do a couple of steps before being able to access the machine, which is different from the process in Terminus. Luckily for you, we have prepared a guide explaining everything you need to know.
How to unlock the Pack-a-Punch in Citadelle des Morts
Once you start a match, the first thing you need to do is to head to the castle entrance. There are two ways to reach it, both to the sides of the fountain statue from the first area.
The one to the right goes through the village, with the Speed Cola machine close to the gates that lead to the castle's courtyard.
On the other hand, the left side has a mud path and you will find the Deadshot Daikiri machine before reaching the courtyard.
Once you reach the castle's Courtyard, you will see that the main door is locked and can't be opened by spending essence points.
The next thing you have to do is go to the top of the stone rampart that is directly in front of the main entrance, where the cannon is located. Simply follow the path to the left or right from outside of the main door. You will have to spend your points on one door to access the rampart.
Once you reach it, you will have to interact with the cannon's wheel to rotate it 180 degrees until the lion's mouth points to the castle's entrance.
After you start interacting with the cannon's wheel, you have to rotate it in one go. If you let it go before it's fully rotated, it will return to its original position.
Once the cannon is in position, interact with the back of it to shoot the entrance.
Now that the entrance door has been destroyed, you can access the castle and continue making your way to the Pack-a-Punch room.
You can follow the path to the right or left of the main staircase in the entrance hall. Open the doors and you will eventually reach the dining hall, with the knight statues on the ground floor and the Vulture Aid perk machine on the second floor.
Take the passage on the right side of the ground floor to descend to the dungeon area. Then go to the end of the room, open the door, and follow the path until you reach the Dubliette Room.
Here you will find a large turquoise crate that is locked with three locks. Simply shoot at them with any gun you have to break them and open the crate.
When the crate opens, a Doppelghast, the map's new enemy, will spawn and you have to defeat it. The creature does damage when it's close to you and moves quickly, so simply keep your distance while you're shooting at it.
After defeating it, the Doppelghast will drop a red Blood Aetherium Crystal. Pick it up and interact with the portal inside the crate you just opened.
The portal will disappear and the Pack-a-Punch machine will come out of it, ready to upgrade your weapons if you have the required essence.
