Each Zombies map inCall of Duty: Black Ops 6features a main quest that you can complete, usually involving multiple steps and more complicated tasks. However, this isn’t the only activity available, as there are many other shorter and rewarding Easter eggs you can complete, which can even help you progress in the main Easter egg quest.

The Chess Knight is one of the many Easter eggs you can find in Citadelle des Morts. To begin, you need to locate the knight chess piece, which can spawn in different locations. Once you find it, you can initiate this unique Easter egg. If completed correctly, it will summon a companion knight chess to assist you in killing zombies, making it a valuable ally during your fight.
