Know the Layout Before You Play

Citadelle des Morts is complex and multi-tiered. It features underground crypts, surface-level courtyards, armory halls, prison cells, and the iconic bell tower that can serve as both a sniping perch and last-stand zone. Familiarizing yourself with the layout is essential.

Before jumping into a serious solo run, take time in casual games to explore:

Power switch locations

Perk spawn points

Wall-buy weapon positions

Fast escape routes

Portal and trap mechanisms

Power On Early

The Power Switch is located in the Inner Courtyard, guarded by multiple zombie spawn points. Turning on the power early grants access to perk machines, the Pack-a-Punch machine, and trap systems that are crucial for survival.

Activate power by Round 5 to ensure you can get set up before the tougher zombie types start spawning. Once power is on, prioritize unlocking key areas such as the Upper Ramparts and the Crypts, which offer ideal training and camping spots.

Early Round Strategy (Rounds 1–10)

Stick to the starting pistol and aim for headshots for maximum points.

Purchase the Luger P12 or the pump-action shotgun off the wall early for better efficiency.

Train zombies in the Fountain Square and keep a tight circle. Always leave one crawler to give yourself time to explore and activate systems.

Use this phase to accumulate points, unlock areas, and prepare your class.

Mid Game Strategy (Rounds 11–25)

At this stage, enemy variants like Screechers and Blazing Undead begin appearing. Speed and damage output become critical.

Perks to Prioritize:

Juggernaut: Found near the prison block.

Speed Cola: In the Armory Hall.

Dying Wish: At the Bell Tower entrance.

Deadshot Dealer: In the Crypt Basement.

Weapons to Use:

D1.3 Sector with Ricochet Blades (excellent for closed spaces).

RPK-LMG for crowd control.

M1911 upgraded through Pack-a-Punch becomes a solid secondary for quick bursts.

Set up camp at the Upper Ramparts with the trap and quick escape path to the lower bridge for backup. This zone provides space to train zombies while having fallback safety.

Pack-a-Punch Access

To access the Pack-a-Punch:

1. Activate three soul urns across the map.

2. Clear the mini-boss guardian in the Catacombs.

3. Link teleporters between the Bell Tower and Inner Courtyard.

Always PaP your weapons by Round 15. Begin with your primary and rotate based on ammo availability.

Boss Waves and How to Handle Them

Starting at Round 15, the Guardian appears every five rounds. This boss can phase through walls and negate traps. Use stun grenades, LMGs, and the D1.3 Blades to chip him down while using teleporters to reposition.

Never try to out-run the Guardian in tight spaces. Always have a charge of Dying Wish ready.

High Round Strategy (Rounds 26 and Beyond)

Here, ammo conservation, perk management, and consistent training become essential.

Use the Bell Tower circle method: create a loop from the tower down into the Hall of Echoes and back up.

Alternate between two PaP weapons to ensure you always have ammo.

Use traps for guaranteed kills every few rounds.

Zombies will begin sprinting non-stop; precision movement is necessary.

Re-buying perks after going down can be difficult, so keep extra cash on hand (10,000 points minimum).

Special Tips:

Use Monkey Bombs or the new Decoy Lanterns to reset tight situations.

Don’t camp after Round 30 — mobility is your best friend.

Learn the quick-rebuild routes between the Armory and Crypt levels.

Always leave a crawler at the end of intense rounds to reset, rearm, or PaP.

Final Loadout Recommendation:

Primary: RPK or D1.3 Sector (with PaP mods)

Secondary: PaP M1911 or explosive launcher for boss wave clearing

Equipment: Monkey Bombs or Decoy Lanterns, Thermite

Perks: Juggernaut, Speed Cola, Dying Wish, Elemental Pop

Field Upgrade: Ring of Fire or Frost Blast depending on your training style

Conclusion

Citadelle des Morts is a brutal test of patience, reflexes, and map knowledge. Going solo here is as rewarding as it is challenging. Stick to the fundamentals — power early, train smart, upgrade often, and stay mobile. With the right strategy, this fortress of death becomes a playground of survival mastery.

Mastering Citadelle in solo runs will not only help you reach high rounds, but also refine your mechanics, map awareness, and instincts — all of which are transferable to other Zombies experiences in Black Ops 6.
