How to Pack-a-Punch on Citadelle des Morts - Call of Duty: Black Ops 6 Guide - IGN

Jun 05, 2025

Pack-a-Punching your weapon is an essential step in the Citadelle des Morts Easter Egg, as it provides the necessary weapon upgrades needed to take on the challenging encounters you'll face during later rounds. This guide explains everything you need to know about pack-a-punching your weapon on Citadelle des Morts in BO6 Zombies.

To Pack-a-Punch in Citadelle des Morts, you'll first want to open either the eastern or western gates in the Town Hall. It doesn't matter which, as you'll eventually need to unlock all paths to complete the Wonder Weapons and Citadelle des Morts Easter Egg.

Once you reach the Courtyard, open the door west of the Entrance Hall and follow the path around the castle wall until you reach the cannon. Now is a good time to start training some Zombies, as you'll need some space to perform the next task.

When you've created space between you and any trailing Zombies, begin cranking the cannon until the rotation bar is filled. Much like the Water Valve on Liberty Falls, you may need to stop cranking to lure away any Zombies temporarily, but just be quick, as the cannon's rotation will retreat.

Once the cannon is rotated, interact with it to blast open the castle's main door.

Now, follow the waypoint markers through the Entrance Hall, Dining Hall, and Dungeon until you reach the Dubliette Room. Here, you'll find a large blue shipping container near the center of the room.

On the door of the shipping container, you'll find three locks--break the locks by shooting them off. Upon breaking the locks, a Doppelghast will come crashing out of the container and charge toward you.

The Doppelghast is a powerful mini-boss, and we highly recommend keeping on the move, especially as the boss charges you. Using the pillars throughout the room can also be helpful to slow down the creature and create angles to shoot without the worry of taking damage.

Upon killing the Doppelghast, stand back and wait for it to explode. Pick up the Blood Aetherium Crystal that it drops on the ground, and then insert the crystal into the red portal inside the container to activate the Pack-a-Punch machine, which will now appear inside the container.
