As you step into the Knights room at Citadelle des Morts, a mysterious sound from a machine may have caught your attention. This machine emits a secret message that holds the key to a nearby locked door. Here’s how to solve the Morse code puzzle in Black Ops 6 Zombies.
BO6 Zombies Morse code solution
To uncover BO6 Zombies’ Morse code secret, complete the following steps in order:
- Play as the Operator Maya
- Wait until Round 12
- Interact with the machine in the Knights’ room
- Listen to a short dialogue scene between Franco and Maya
- Interact with the door after the conversation
- Defeat the Laurent mini-boss
- Pick up the Key
- Walk further into the room and use the Key on the large door
- Watch an exclusive Maya Easter Egg cutscene
- Claim rewards
Since the Morse code secret ties into an exclusive Maya cutscene, it’s essential to equip her before the match. You can find the machine with the Morse code message in the Knights room at F0 coordinates, the same area as the elemental Bastard swords.
Go to the left of the Deadshot Daquiri Perk machine to locate the device. However, you’ll need to wait until Round 12 for the Maya Easter Egg to trigger. Use this time to gather resources like Perk Colas and a Pack-a-Punch machine upgrade. You’ll definitely need these enhancements later on, as the mini-boss fight can be challenging without it.
Once you’ve reached this round, press the Interact button (same as Reload) near the machine. Maya will trick Franco into unlocking the door. You can now interact with the door to open it. The mini-boss fight with Laurent commences right after, forcing you to take down a Doppelghast. Vermin will be going at you, too, but I suggest keeping your focus on the boss. The Vermin will keep spawning no matter what, so try to ignore them if you can.
Eliminate Laurent to pick up the Key for the locked door ahead. Open the door, and you’ll unlock a secret cutscene. It ties up some loose ends from the Terminus Main Quest and rewards you with a few gifts. In particular, it always offers a Legendary rarity weapon and a random piece of equipment. Thus, if you want a powerful gun for free, set aside some time during Round 12 to claim it.
