The updated Zombies game mode in Call of Duty: Black Ops 6 has been received well by veterans and newcomers alike. Zombies is historically known for its convoluted Easter Eggs and secrets. Going from small secrets in World at War‘s Der Riese to elaborate series-spanning celebratory questlines like Black Ops 3‘s Revelations, the Easter Eggs are a big part of the mode’s identity, and Zombies fans expected no less in the newest maps in Black Ops 6: Liberty Falls and Terminus.
