Firebase Z is currently live in Call of Duty: Black Ops Cold War and players can freely explore the map. Similar to the easter egg present in Die Maschine, Treyarch has included another Easter egg in the Firebase Z map as well. However, the Easter egg is yet to be revealed as Treyarch is scheduled to release the same within a few hours.

UPDATE: The #FirebaseZ main Easter Egg quest will now be enabled at 10AM PT / 1PM ET / 6PM GMT Friday, Feb. 5th.Rest up and hydrate before the hunt begins!

This delay is because Treyarch wants to ensure that "everyone can start the hunt on equal footing." Although the Firebase Z map is currently live in Call of Duty: Black Ops Cold War, players will be able to hunt for the easter egg from 10 a.m. Pacific Time on February 5th.

The following is a rundown of everything that players should know before heading into Firebase Z to uncover the hidden Easter egg.

Firebase Z Easter egg in Call of Duty: Black Ops Cold War

It took players a little more than three hours to uncover the hidden Easter egg in Die Maschine after it was released. Given that the latest update containing the Firebase Z map was released at an unusual time, making it difficult for everyone to track the hidden Easter egg.

That has led to Treyarch delaying the Easter egg's reveal by a few hours to ensure maximum community participation. However, judging by the treasure present on Die Maschine, players should expect the Firebase Z iteration to be similar to its predecessor.

It is tough to determine what the Easter egg might be referencing. Call of Duty: Black Ops Cold War's first Easter egg proposed that the developers keep up with trending social media references. Nevertheless, the developers can also choose to go a different route.
