One such side easter egg is the Demented Echos zombies easter egg specific to the Outbreak mode in Black Ops Cold War zombies. This easter egg also has a unique calling card associated with it, for bragging rights, as completing this side easter egg is no easy feat.
To complete this easter egg, you must find a total of ten demented echo zombies while playing the Outbreak game mode. These fiery hot (literally) zombies spawn randomly in each region in a set number of locations. But, only one spawns at each difficulty level. This means if you find one during difficulty level 1, you can only find the next one on difficulty level 2 in whatever your next region is. These zombies resemble the same fire zombie that was added as a jumpscare in Die Maschine when you successfully complete the floating zombies easter egg.
When you find these zombies, you must keep your distance and approach them slowly, as they will suddenly lunge towards you. If they manage to reach you, they explode, setting you on fire and spawning many regular and elite zombies. You must kill them before they reach you.
Upon successfully killing the demented echo zombie, you will get a “hush” medal. You must get ten “hush” medals to get the “Restful Spirit” calling card as a reward.
This guide shows you all the demented echo zombie locations that we’ve managed to find so far in each region. There could very well be more than what we’ve stated below. Feel free to comment below if you find new locations!
