Paradox Junction — Black Ops 7 Zombies Easter Egg Guide

Read this first — it governs the whole quest. The map has two Nuketown timelines: Destroyed (where you start) and Past (pre-nuke). It flips automatically at every dog round, the first around round 5 or 6; otherwise use the portal, which costs points and needs a round flip to recharge if it says regenerating. Some steps refuse to run on dog rounds, and every step below names the timeline it needs — match it or nothing happens.

(Destroyed) Open toward the back of the yellow house and take the truck keys from the zombie stabbed with a golf club. While you are there, grab the SO3 vial from the desk upstairs and fill it with acid at the greenhouse kitchen sink — interact with the sink, then the acid pool.

(Past) Use the keys on the truck to roll it aside and open Trinity Avenue. Then destroy the space-time knots around Pack-a-Punch: shoot a knot, kill the tethered zombies that drop from the sky, and the knot reappears elsewhere. Three or four cycles and Pack-a-Punch lands.

Grab while you are in the Past: the sealant from the upstairs shelves in the yellow house, and the swing seat from the swing set behind it.

Perks you will need later: Wisp Tea and Death Perception. Machine locations are randomised between the two timelines, so buy them wherever you find them, with WunderFizz as the fallback.

Quick win: The Nuketown clock pays loot at any round: shoot its hands (the clock is knocked down near spawn) until it reads 1:15, then when you next change timeline collect the drop at the clock — a Mystery Perk can, salvage, an Aether Tool and a Pack-a-Punch crystal are all reported, and it scales with the round. While you are in the Yellow House backyard for the keys, the mini-golf course is right there in the Clean timeline: shoot or melee a ball into the white-flag hole in one and it drops Bonus Points, Insta-Kill and Max Armor (a second sink a round or two later pays another Bonus Points). No explosives — they launch the ball out of the court.

Quick win: Intel on the doorstep: Helpful Information on the Yellow House kitchen table (Clean), Live Air on the brick-oven slab in the Yellow House backyard (Clean), The Search Begins on the broken bunk bed upstairs in the Destroyed Yellow House, Run Aground in the upstairs cabinet of the Destroyed Green House, Dead Air on its deck railing, Paper Hearts on the living-room table by its stairs.

Cursed only — The Rocket relic's dog-petting and the Summoning Key's collar and ball can all be done before round 20/40 — only the final pet and the gravestone step are gated.

Four parts in any order, then build in Destroyed at the van in the middle of the map. Melee the workbench first — there is no prompt at all until you do — then interact to craft, and remember to take the weapon off the bench.

Worth doing anyway: fill every soul-cyst you find, not just the ringing one. They drop loot, and at high rounds tier-3 Pack-a-Punch crystals.

Quick win: While you are pouring acid: melt all twelve mannequins (three per vial, refill at the sink) — the last one you melt leaves a free Random Perk power-up where it stood when you return to the future, and the other spots pay about 1,200 essence between them. Mannequins: Green House kitchen, behind the backyard fence, the back deck and the garage; Cul-de-Sac north-east corner left of the Yellow House and before the truck to Trinity Avenue; Yellow House by the stairs, backyard by the swings and behind the house left of the garage; Trinity Avenue by the right-hand garage door, near the M8A1 wall-buy and far right of Pack-a-Punch.

• Barrel — in Destroyed, one yellow soul-cyst emits a ringing tone. Kill zombies beside it until it bursts
• Mannequin part — in Destroyed, find the one ringing mannequin (they stand in the greenhouse, yellow house, spawn and Trinity Avenue) and memorise which. In the Past, interact with that same mannequin to pour the acid on its head — a twins quote confirms a correct guess, and you get three tries. Return to Destroyed and the part lies where it stood
• Wall part — in Destroyed, find the ringing black-goo wall mark (top of the greenhouse stairs on the right, the yellow-house garage, or the corridor entering Trinity Avenue). In the Past, throw an explosive at that exact spot; back in Destroyed the opened wall holds the part
• Sealant — the upstairs shelf in the yellow house in the Past, bottom shelf by the window

Spend a full round in Destroyed, and at the next round start a tortured zombie spawns held inside a small fire tornado — behind the yellow house, behind the greenhouse, or on Trinity Avenue near Pack-a-Punch. It stays put until you approach.

Do it at the end of a round. When you approach it follows you, and purple-eyed zombies spawn that chain fire into it and drain its life — kill those off it as you go.

Lead it to the Blundergat van and kill it with the Blundergat right in front of the bench so its soul is drawn in. Repeat on two later rounds; missing a round is fine, a fresh tornado appears each time.

The third one is different: it transforms into a shock mimic as you approach, with far more health. Pack-a-Punch the Blundergat before you attempt it.

Finish: in the Past, melee the bench flap open and insert the Blundergat. Return to Destroyed, melee the bench, and collect the Sundergat.

Quick win: Collecting the Sundergat from the truck also banks the Sundergat artifact; Head Cannon sits on the truck bonnet right of Pack-a-Punch in the Clean timeline and Makin' It Right on the car bonnet opposite Pack-a-Punch in the Destroyed one.

(Destroyed) From around round 8, with all doors open in both timelines, find the ARC-XD remote — right of Pack-a-Punch behind the crates, on the broken shelf in the yellow-house garage, or in the greenhouse back-garden soil bed. Interact to become the RC car.

The route: up the box ramp, along, left, then up the second ramp facing the boxes. Build momentum and jump early to clear them, through the crack, then drive to the garage door and detonate. Fail it and you find another remote next round.

Inside the opened garage a stone zombie fades away — pick up the head and then the chalk piece on the floor.

(Destroyed) Interact with the swing to fit the seat, then again to place the chalk.

Confirmation cue: a white flash and a vision of the twins on the swings. Every later interaction with the girls requires this step first.

Quick win: The stone corpse in the opened garage also hands you the Sidewalk Chalk artifact. Now start the chalk chain: interact twice with the drawing on the yellow shed in the Destroyed Yellow House backyard (Before Times), the drawing on the white fence in the Clean Green House garden (Storm Coming), then the Trinity Avenue street drawing in Destroyed (Trickery) and finally the one behind the Welcome to Nuketown sign in Clean (Aftermath) — each only appears after the one before.

Do this as soon as the twins appear — it gates the jacks game later and it is pure waiting, so start the clock on it early.

(Destroyed) Wait around the greenhouse backyard watching the back-left arch with the flower bed. Toward the end of a round the piano teacher shuffles in through the fences. Do not kill her. If she does not appear, spend the whole next round there.

Turn her with Brain Rot or a psych grenade and she runs to the piano inside the greenhouse and stands at it.

Now move fast: while she stands there you have limited time to reach the portal and teleport to the Past. In the Past she has opened the piano, plays briefly and leaves.

Confirmation cue: blue note symbols spawn around Destroyed.

(Destroyed) In the yellow-house garage, crouch and interact with the red box on the shelf — it only opens after the twins step — for the irradiated seeds.

(Past) Plant them in the dirt pile left of Pack-a-Punch. A glowing plant appears and acts as a soul box: kill zombies with the Blundergat beside it — the base version is fine here, and it takes plenty of kills. White flash and a Max Ammo confirm it.

(Destroyed) The tree is now huge. Hit it with three tomahawks for three strange firewood logs — the quote is “that’s plenty of wood”. Craft more tomahawks at the bench as needed.

(Past) Place the firewood in the yellow-house fireplace and Molotov it. A completion quote plays, and back in Destroyed the wood has burned away.

Goggles (Destroyed): shoot the goggles on top of the telephone pole left of Pack-a-Punch — aim the very top — and they fall out of bounds. Activate Wisp Tea and the wisp carries them back through the fence for you to collect.

Headset (Destroyed): you need Death Perception to even see it. It spawns on the greenhouse upstairs shelf, in the trash bins by the wall-buy fence, or behind the yellow house in the mannequin’s hand near the golf-bag body.

(Past) Open the toy box at the Trinity Avenue entrance — interact once to open, again to load — and place both items. That unlocks the third children’s game.

Quick win: Both pick-ups are intel artifacts (Goggles, Headset) — nothing extra to do.

(Destroyed) Stand on the chalk X in Trinity Avenue near Pack-a-Punch until it glows blue and stays lit, then get to the Past.

At the X the twins draw a hopscotch grid. Interact with the white orb over square 1 to start a third-person mini-game: jump square by square 1 to 12 and back to 1, dodging the moving black smoke square.

The rhythm that works: hop the black square as it passes, then follow it home — it wraps from your start straight back to 11.

Fail cooldown is 60 seconds, regardless of the round, so a botched attempt does not cost you a full round.

Finish: a gold music box appears. Escort it with Sundergat kills only — no other weapon fills it — all the way to the fireplace in the yellow house, the long way round through the garden and back kitchen. Max Ammo on arrival.

Quick win: The gold music box you escort is the Music Box artifact once it reaches the fireplace.

(Destroyed) Find the red ball phasing in and out of reality — in the Trinity Avenue rafters, on the yellow-house roof, or on the stacked ammo crates in the backyard. If it is not there, flip the round. A PhD Flopper slide-explosion knocks it down nicely.

Shoot the ball along the ground all the way to the X behind the greenhouse until the X glows, then leave it and teleport to the Past.

The twins draw a four-square grid with a floating blue ball. Melee it so it bounces into a different square each time — never twice into the same square. Solo, you run to the opposite square yourself, about fifteen seconds; in co-op a partner returns it and it runs about thirty. Shrouds and decoys make it trivial.

Finish: a gold symbols item — Sundergat-escort it to the toy box in Trinity Avenue. Max Ammo and a white flash.

Needs the piano teacher done first — if the notes are not interactable at all, your tree soul-box is unfinished.

(Destroyed) Eight blue notes sit at fixed spawns: behind the bunker at the greenhouse, behind the yellow-house fence, the spawn-area fence, the side of the yellow bus, and several around Trinity Avenue including the wooden panel by the phone box and behind the rock near the tree. Each blinks between one and eight times.

Count all eight first, then interact in blink order 1 to 8. Get it wrong and you wait for the next round.

(Past) At the greenhouse piano, eight glowing notes are marked on the wall. The tune is the same every game — A (high), F, G, E, F, E, C, E. Wrong notes reset after roughly thirty to sixty seconds.

(Destroyed) Find the floating sideways zombies around the map edges and kill three; their souls fly to Trinity Avenue. Go to the Past, the souls sink, and the twins draw jacks.

The game: the ball bounces and each bounce flings a wave of one-hit-kill zombies into the air — kill every airborne zombie before the ball lands. Line them up for collaterals; in co-op split the lanes. Several waves, 60-second retry on failure.

Finish: Sundergat-escort the gold item through the greenhouse garage, round the back, through the kitchen and onto the piano.

(Destroyed) From the top of the bus by the Blundergat van, shoot the big clock above the greenhouse: white hand to 12 first, then the red hand to 12.

The bit everyone misses: start the teleport to the Past and, during the teleport animation, shoot the red hand once more — nudging it to 12:05. It has to happen mid-teleport.

Confirmation cue: you arrive in the Past to music, with the twins at the greenhouse piano. Follow their orb through piano, toy box, fireplace, swing set, listening at each stop. At the swings it becomes a yellow orb — the boss vote.

Prep: triple Pack-a-Punch, max rarity, purple or better armour and 15,000+ points spare. Bring Kazimirs and monkeys for the defences.

Each cycle runs the same shape: break three black-goo blobs, hold three 60-second concentration-field defences, then get a damage window on the spinning heart — shoot the glowing cracks top and bottom. Max armour and Max Ammo drop after each third of its health.

Navigating the defences: the blue orb flying onward shows which site is next. Failing a defence only restarts that defence, not the cycle.

Cycle 1: the blobs carry soul cysts needing eight to ten kills each beside them. The boss throws missiles and fire tornadoes — keep moving, and you can damage it from anywhere in the arena.

Cycle 2: blobs are fed by a yellow sky-vortex dropping tethered zombies, just like the Pack-a-Punch knots — kill the tethered zombies to break each blob. Meteors mark the floor with orange circles, and hellhounds join the defences.

Cycle 3: a tortured zombie spawns centre-arena. Escort it to each blob — killing its purple-eyed drainers on the way — and once it tethers itself, shoot the tortured zombie to break the blob. Three times, then the defences again, then the final damage phase with the heart spinning fastest. Dump everything: Idle Eyes in co-op, Aether Shroud otherwise, Kazimirs during the defences.

Needs confirming: the blob-to-location mapping. MrDalekJD names fireplace at Trinity Avenue, toy box at the greenhouse and piano at the yellow house — but the main quest escorts deliver to the opposite pairings, so cross-check in game.
