Nuketown Zombies BO3 Custom: Secrets

The space teddies

Three teddy bears wearing astronaut helmets are hidden around Nuketown Zombies, According to the guide and the scripts of the mod-friendly version, each sits on one of several possible spots drawn at random, and shooting all three raises the perk limit by one for the whole game. Players have reported one on top of the clock tower and one behind a house; one player wrote that they must be shot with the Ray Gun, which no other source confirms.

The songs

The musical Easter eggs of Black Ops II are back. A guide of the mod-friendly version lists three of them:

The teddy bear sitting behind the broken window of the yellow bus, Nuketown Zombies BO3 Custom, Call of Duty Black Ops III Zombies

Samantha’s Lullaby

Three interactions: the teddy bear in the yellow bus, a second one in the backyard of the green house, and the third upstairs in the yellow house.

The mannequin heads

Shooting the heads off every mannequin plays a song; in the mod-friendly version it also gives a perk slot.

The clock door

In that guide, when the clock hand points to one and the population sign shows exactly 15, open the 3000 door of the yellow house backyard and take its power-up.

The clock door

In the backyard of the yellow house, a door sold for 3000 points hides a power-up. According to the scripts of the mod-friendly version, the hand of the Doomsday Clock moves each time the population sign at the end of the street passes 33, 66 or 99 zombies killed, and the power-up behind the door changes with it, in a cycle of Nuke, Double Points, Insta-Kill, Fire Sale and Max Ammo.

The population sign

The “Welcome to Nuketown” sign at the end of the street counts the zombies killed, on two digits.

Round 25

At round 25, Richtofen takes control of the zombies on the Moon: their eyes turn from yellow to blue and he replaces Samantha as the announcer. During the rounds before, his transmissions play on the television of the green house.

Marlton’s shelter

In the backyard of the green house stands the fallout shelter where Marlton Johnson, the TranZit survivor, hid during the blast of Black Ops II. A guide of the mod-friendly version shows that knifing its door plays one of his lines. No source says it works on the Legacy build, and on the Legacy page a player asked in 2025 to “hear Marlton back in the Bunker again”.

Out of bounds

Beyond the fences, players have spotted wall weapons such as a Type 25, a Mystery Box spot to the right of the yellow house, a bunker, and a PhD Flopper and a Der Wunderfizz machine. None of them can be reached in a normal game.
