Call of Duty: Warzone's new Pacific-themed Caldera map launched on December 8, and while there doesn't seem to be any Easter eggs activated yet, there are plenty of places on the island to keep an eye on as seasons progress.

Much like Modern Warfare's Warzone Easter egg quest with the large military bunkers, Caldera has a secret bunker of its own. This door is also styled exactly like the original bunkers on Verdansk, and it appears to be the only bunker on the map that matches the styling of Verdansk. At this time, there doesn't seem to be any keycards dropping, which is what led to the original Verdansk bunkers to open.

Additionally, you can also find several circular bunker hatches all around the island. These hatches are likely to open at some point, as they match the hatch design of the bunker Captain Butcher teased in a previous Season 1 story trailer for Caldera. The cinematic showed Butcher's plane crash-landed on the island coast, where he discovered a hatch on the beach. He opened the hatch and headed inside the Nazi bunker, saying "the world would never be ready for what I found."
