In Call of Duty: Black Ops 6, each Zombies map includes a main quest that consists of various steps and complex tasks. However, there are also several shorter Easter eggs that you can complete, which can be quite beneficial and may even aid you in the main Easter egg quest.
One of these Easter eggs is the Chess Knight, which can be found in Citadelle des Morts. To start, you’ll need to find the knight chess piece, which spawns in different locations. Once you have it, you can activate this unique Easter egg. If done correctly, a knight chess companion will join you and help fight off zombies, offering substantial support during battles.
Finding the Chess Knight Piece
First Location
The first potential spot for the Chess Knight piece is in the bar’s basement, close to the spawn area.
Look for a cabinet filled with various bottles and cans. You should see the white knight chess piece wedged between them.
Second Location
If the chess piece isn’t in the basement, check the area just before entering the castle. Go to the room with the Elemental Pop machine.
On the left side of this room, opposite the machine, you’ll find a table next to a server where the white knight chess piece may be located.
Third Location
If you still haven’t found the chess knight piece, head inside the castle and climb the stairs to the upper level with the dragon statue.
Take the path on the right, and right after passing through a door, you will see a table with the knight chess piece on it.
There may be additional locations for the Chess Knight piece to spawn, but currently, we only know of these three.
Completing the Chess Knight Easter Egg
With the Chess Knight piece in your possession, you can start the Easter egg. Make your way to the west side of the castle, specifically to the room housing the Stamin-Up machine.
In the center of this room, you’ll find a table with a chessboard. With the chess piece, interact with the board to activate a purple circle.
Your task is to defeat several zombies while standing inside the circle.
After successfully completing this, the Chess Knight piece will appear as your companion and will assist you in taking down zombies for a significant duration.
