Call of Duty Season 4 Reloaded has introduced the new Kowakujo map to Black Ops 7 Zombies, complete with a hidden Easter egg song titled "Evencry." This track, composed by Kevin Sherwood and featuring vocalists Cole Rolland and Malukah, can be unlocked by locating and interacting with three hidden pairs of headphones scattered across the map.
Locating the Headphones
The headphones are identifiable by their blue color and fuzzy bunny-like ears, reminiscent of the "Mister Peeks" character. They can be found and interacted with in any order during a match.
One headset is situated in the Stables, near the Death Perception perk machine and the Mystery Box spawn. It can be found to the right of stacked boxes in a corner.
A second headset is located in the Onsen Baths, a room to the right of the Elemental Pop perk machine. Although it may not appear visually, interacting with the area near cubbies with towels and sandals should trigger the music cue to confirm its activation.
The third headset is in the Kitchens, the same area that houses the Double Tap perk machine. It is located inside a large wooden bowl on a lower shelf.
Upon interacting with all three hidden headphones, the Easter egg song "Evencry" will play. This process can only be completed once per match.
