Like all Treyarch games, Black Ops Cold War's Zombies Mode is packed full of hidden Easter eggs. Most of them have likely been found at this point, but there are still a few that have us confused.
Those players who have been spending time with Black Ops Cold War's Zombies mode will likely have witnessed more than a few Easter eggs for themselves.
After all, the standard wave-survival mode that pits players against hordes of undead is only the beginning. Black Ops Cold War Zombies also contains a hidden story, and dozens of Easter eggs to uncover.
But even after weeks of searching, there are some Easter eggs that still remain unsolved. These hidden clues might point towards an undiscovered part of the game or something coming in the future.
Whether there's another Die Maschine Easter egg song to find or a new hidden area, here are the unsolved mysteries of Cold War Zombies.
Black Ops Cold War Zombies Undiscovered Easter Eggs
The Elder Gods
Those who pay attention to the Die Maschine backgrounds at later rounds may have noticed some giant figures walking around outside the confines of the map. These giants don't interact with the players, even when glitching outside of the area, but we do know a little about them.
In the game files, these creatures are referred to as The Summoners. These boss creatures are also made up of dozens of undead bodies, fused together like the Panzermorder from CoD WWII.
A series of in-game intel refers to the creatures as Elder Gods, and graffiti on a Crash Site wing does indicate that the wrath of Czernobog 'The Black God' is coming. Whether these gods will eventually be a part of the Cold War Zombies story is yet unknown.
When entering the Dark Aether, players quickly discovered a few ghosts lurking about inside the void. And no, we're not referring to the Spectral Reflections, which you can bring in through Anomalies.
As well as these figures, players are finding that there are 20 ghostly monkeys lurking around the game's map. None of the creatures do much more than sit there at the moment, but there has to be a reason that they're present.
Players believe that these ghost animals could be related to the iconic Zombies Monkey Bomb item. As of yet, we're yet to discover exactly how to trigger the Easter egg, if indeed there's something worth seeing at all.
Some Zombies fans even speculate that these monkeys may have wandered through a portal connected with the upcoming Cold War Zombies map, set in Vietnam.
Hidden Rewards Station
In Black Ops Cold War Zombies, players can access Rewards Stations once completing trials for bonus weapons and more. However, one Reward Station, or something that resembles one, is actually hiding outside of the playable area.
As you can see, there's a hidden Reward Station hiding in the Weapons Lab, behind a zombie barricade. What's more, players believe that shooting this station actually causes the fuse to spark.
But the biggest mystery of this strange area is that there appears to be a gate contraption above the door. It almost looks like the entire doorway can be lifted out of the way, should players manage to trigger it.
Gold 4 Banana
If they head to the second level of Nacht Der Untoten, players will find a dead soldier in one corner. Next to him, the wall graffiti appears to translate to 'Gold 4 Banana.'
Looking in the game's files, a soldier's picture can be found that looks rather similar to the deceased individual. What's more, he comes with some backstory.
The dead soldier's name is Pyotr, and it appears that there's a way to trigger various radio recordings left behind by the man through a radio. It appears that Pyotr got himself lost in the Dark Aether after being separated from his team.
It could also be that this Easter egg relates to the Cold War Zombies ghost monkeys due to the reference to a banana. However, we're yet to find the trigger event to begin this Easter egg, if there is one.
Even Black Ops Cold War's Nuketown contains a new Easter egg to discover. As a developer, Treyarch certainly spends some time making sure there's replay value for fans.
But right now, the game's community would probably prefer to have a version of Cold War that's not so buggy.
