Best loadout to complete Citadelle des Morts main quest in Black Ops 6 Zombies

After the launch of the new Black Ops 6 Zombies map, Citadelle des Morts, players may wonder which weapons are best suited to complete the main quest. The ideal combination is the PU-21 LMG and the GS45 Akimbo, as these weapons are highly effective for tackling the challenging and time-consuming Easter egg.

While you can only start with one weapon, the GS45 is easily available as a Wall Buy for just 500 Essence right at spawn.

This article will detail the optimal loadouts for both weapons and explain how they can help you complete the Easter egg. Additionally, it will provide tips to simplify your journey through this difficult quest.

Best PU-21 LMG loadout to use in Black Ops 6 Zombies Citadelle des Morts

To maximize the PU-21 LMG's performance, customize it with the following attachments for increased power, speed, and versatility — essential for handling hordes of zombies:

Recommended build:

Optic: Volzhskiy Reflex
Muzzle: Suppressor
Barrel: CHF Barrel
Magazine: Fast Mag I
Rear Grip: Commando Grip
Stock: Light Stock
Laser: Steady Aim Laser
Fire Mod: 5.45x39mm FMJ

The Suppressor increases the chance of extra salvage drops. The CHF Barrel improves the headshot multiplier, allowing headshots to deal significantly more damage. The Fast Mag I ensures faster reload speeds, which is vital in the fast-paced Zombies mode, without compromising much magazine capacity.

For better handling, the Commando Grip enhances aim-down-sight speed and sprint-to-fire speed.

Mobility is improved by the Light Stock, which boosts hip-fire movement speed, overall movement speed, and strafing speed, allowing you to change position quickly.

The Steady Aim Laser tightens hip-fire spread, which becomes essential when your Pack-a-Punched magazine size doubles to 90 rounds, ensuring effective close-range control.

Additionally, the 5.45x39mm FMJ fire mod increases penetration damage, making it highly effective against armored zombies that appear in later rounds.

Lastly, the Volzhskiy Reflex provides a clean sightline for precise aiming, helping you land critical shots consistently.

Recommended build:

Barrel: Reinforced Barrel
Magazine: Extended Mag II
Rear Grip: Ergonomic Grip
Stock: Akimbo GS45
Fire Mod: Rapid Fire

The Akimbo GS45 stock is the key attachment, allowing you to dual-wield the weapon for significantly increased firepower. This setup enhances fire rate, magazine capacity, and range, making it well-suited for the challenges of this map.

The true potential of the GS45 is unlocked through Pack-a-Punch, which transforms its shots into explosive rounds with devastating power. This upgrade ensures the weapon remains effective even in later rounds, making it a reliable choice for high-intensity encounters.

Both weapons complement each other perfectly, especially if you're focusing on the main Easter Egg solo. Defeating the final boss becomes much more manageable with this combination. The boss's primary attacks are only dangerous at close range, so maintaining distance is key to staying safe.

This is where the PU-21 LMG shines. Use it to continuously damage the boss from a distance. When hordes of zombies attack you, switch to the GS45 Akimbo to quickly eliminate multiple enemies at once. This strategy ensures you can handle both the boss and the zombie waves effectively, making the final encounter much more manageable.

GobbleGum Selection for Black Ops 6 Zombies Citadelle des Morts main quest Easter Egg

Here is the GobbleGum selection for tackling the main Easter Egg:

Perkaholic: Grants all Perks immediately.
Wall Power: Lets you buy a Pack-a-Punch Level 1 weapon from a Wall Buy.
Hidden Power: Upgrades your current weapon to Legendary rarity.
Idle Eyes: Temporarily distracts zombies.
Free Fire: Provides unlimited ammo for a short time.

Best strategy

Start with Perkaholic to unlock all Perks at the beginning of the game. Next, use Wall Power to purchase the GS45 handgun from Wall Buy, ensuring it comes pre-upgraded to Pack-a-Punch Level 1. Finally, activate Hidden Power while equipped with the PU-21 LMG to upgrade it to Legendary rarity.

Once your setup is complete, proceed cautiously through the Easter Egg steps. To manage the difficulty of later rounds, try to keep one zombie alive at the end of a round. This allows you to complete Easter Egg objectives without advancing to tougher waves quickly.

Aim to spawn the final boss as quickly as possible, as zombies become increasingly powerful in higher rounds, making it harder to manage them solo.

And while encountering the final boss, The Guardian, don't utilize the Idle Eyes and Free Fire GobbleGums immediately. The battle will happen in three phases and it is recommended you use these two in the final phase.
