Citadelle des Morts

Citadelle des Morts is Black Ops 6’s medieval turn: a castle above a fortified village in the Principality of Avalon, a fictional microstate on France’s Mediterranean coast, built over a leper-colony abbey and ruled in the 1300s by the renegade knight Guy de Saint-Michel — whose enforcers’ line became the French Syndicate that holds it now. A week after Terminus, Weaver, Grey, Carver and Maya arrive to rescue the demonologist Gabriel Krafft, with a newly repentant Ravenov drinking in the tavern below.

Into the castle

The village funnels up from Town Square through the tavern or the hilltop path to the ramparts — where the way into the sealed castle is not a door but the bronze Lion Cannon, rotated 180 degrees and fired at the entrance. Inside: the Entrance Hall’s dragon bust, the two-storey Dining Hall with its four knight statues, and the dungeons running down to the Oubliette.

Power

There is no power switch — like Liberty Falls, everything works as its area opens. The map’s rune-circle Point of Power traps are the exception, waking only after Pack-a-Punch is active.

Pack-a-Punch

In the Oubliette, the lowest cell of the dungeon, a crated machine sits behind three locks. Break them and the map’s first Doppelghast bursts out; kill it, take the Blood Aetherium Crystal it drops, and feed the crystal to the rift in the crate. The machine stays put — this map’s wandering is done by the swords.

The Bastard Swords

Four melee wonder weapons, one per knight of Avalon’s legend: Caliburn (dragon, fire), Durendal (stag, lightning), Balmung (raven, shadow) and Solais (lion, light). Great-helmed zombies drop the stamp that wakes a Dining Hall statue and grants its blade; each sword then has its own elemental ritual — carrying Aether fire between braziers, lightning rods on the ramparts, a cellar puzzle, a lion’s door — to reach its upgraded form. Four matching Incantation scrolls round out the arsenal, and the quest wants everything.

Special enemies

The Doppelghast debuts here — a two-skulled sprinter whose needle bursts blur the screen with hallucinations — alongside Terminus’s Amalgam, armored zombies and Vermin swarms. Notably absent: Manglers, for once.

The main quest

With all four upgraded swords and Incantations in hand, the quest works through Krafft’s cell door, torn pages, an alchemical wall-code and a salute to each knight statue in coded order, then carries a Mystic Orb through four elemental trials to the Secret Study. The Town Square statue is the final door: a stone Guardian golem that drags the squad to a lava arena, shedding weak points through immunity phases as the floor shrinks. Fully soloable; the prize is the Obscurus Altilium, the amulet Krafft says must never reach Richtofen.

Story

The victory costs the mission its point: zombies reach Krafft’s cell as the Guardian falls, and the dying demonologist sends the crew on to a nearby excavation site — The Tomb — with two warnings: the Sentinel Artifact corrupts whoever wields it, and Richtofen is his adopted son, whom he begs Weaver not to kill. Vulture Aid’s return after a twelve-year absence, the perk’s machine standing in the Dining Hall, is the map’s quieter piece of history.
