Alpha Omega — Black Ops 4 Zombies Easter Egg Guide

Open the houses and drop into the bunker. Clear the ventilation objective and switch on the power — a Nova-6 Bomber horde spawns while you repair the leaking house vents, so keep zombies off the vent panels. Pack-a-Punch comes online in Beds after the setup. Then interact with Rushmore’s terminal in Operations and wait through the dialogue until he accepts inputs and gives quest prompts. Entering 2265 into Rushmore grants everyone a free 1,000 points — handy toward the 6,750 Galvaknuckles route.

Solo vs co-op: fully solo-capable throughout. Co-op only speeds crowd control and lets players cover separate clocks/pictures — no step changes count or timing in your favour except that a teammate can hold zombies off a timed input.

Buy Galvaknuckles from the Cul-de-sac truck. Find the static (blank-screen) TV and melee a zombie right beside it with the Galvaknuckles — the shock powers the TV, which displays a test card of five letter/time combinations (e.g. D0745) in a fixed spoken order. Write down all five.

• TV site 1 — Beds, right of Pack-a-Punch
• TV site 2 — Beds, left of Pack-a-Punch
• TV site 3 — Lounge

Each broadcast letter maps to a fixed clock — A = Yellow House, B = Green House, C = Prisoner Holding, D = Transfusion, E = Operations, F = APD Interrogation. Visit the matching clock and set its time in the exact broadcast order: hold interact = +15 minutes, melee = +1 hour. When all five register, interact with the one clock you never used — its hands spin and stop on a new time. Convert that to four digits and enter it into Rushmore. The success cue is Rushmore’s line “Nope! Still don’t trust you.” and free Pack-a-Punched weapons: the Ray Gun Mark II (Porter’s X2) in Operations and another dispensed in Prisoner Holding.

Per-match cipher: the five pairs and the unused-clock value are randomised every game — read them live and set in spoken order. There are only six fixed code sets, so hearing the first code identifies the whole set (credit GregFPS) — you don't have to catch all five. If the sequence resets, wait a round, re-listen, and re-enter exactly.

• The six clocks are in Yellow House, Green House, Prisoner Holding, Transfusion, Operations, and APD Interrogation
• One of these six is the unused clock — read whichever you did not set

Ask Rushmore for the next task and search the underground for the unique red Nova-6 Crawler. Walk close enough that it follows you to the barrier right of the RK7 wall-buy in Transfusion. Infinite zombies spawn on the way.

Critical: a single stray bullet kills the crawler and forces you to wait until the next round for a new one. Control ordinary zombies with equipment, cover or pathing — never shoot near it. If it wanders off, back-track and re-bait it, or reset on the next round.

Collect and insert the required component to wake Sergeant A.D.A.M. (the walking robot; learn his escort/command interaction). Then melee the hidden door on the stairs between Green House Backyard and the Diner until Marlton speaks. Escort A.D.A.M. to that door — spooked, Marlton throws out a 115 canister. Pick it up and place it on the shelf left of the Green House Backyard doorway in Transfusion.

• Wake A.D.A.M. (build/insert component) before approaching Marlton
• Melee Marlton’s door until he speaks
• Bring A.D.A.M. to the door → collect the thrown 115 canister
• Place the canister on the Transfusion shelf

Pre-place your two Telepads: one at Power House, one in the Prisoner Holding backyard, and test the route first. Bait a Jolting Jack’s electric blast into the server core housing left of the Telepad location to crack it open. Take the core, teleport, and sprint to Operations to insert it in the server before the timer expires (the window is tight — roughly ten seconds, so the pre-placed teleport route is mandatory).

Recovery: a failed timer immediately respawns another core, so retry as many times as needed. Keep every door between Power House, Prisoner Holding backyard and Operations open before you start.

Put Brain Rot on a controllable weapon. Shoot a zombie beside each green-mist picture — the turned zombie tears it down, revealing a four-digit code. Record all three, then enter them into Rushmore one after another within sixty seconds and interact; if the window lapses, re-enter the full set. A blackout follows: set the six switches to the fixed pattern, then restore main power at Power House and report to Rushmore. All switch lights turn green when correct.

Fixed switch pattern: Diner UP · Beds UP · Lounge DOWN · Generators UP · Storage DOWN · Solitary DOWN.

• Picture 1 — top of the Green House stairs
• Picture 2 — Lounge, left of the bunker exit
• Picture 3 — Beds, across from the KN-47 wall-buy

Find a blue-glowing mannequin and interact to start a ~one-minute lockdown — survival, not kills, is the objective. It shatters and drops a body part; repeat for three parts. Place all three on the broken seated mannequin in APD Interrogation. Then find the elemental orb in a zombie-spawn window and escort it back to the rebuilt mannequin — stay close or it despawns and returns next round. Wait for all dialogue before touching Rushmore.

Optional aid: enter 3279 or 6662 into Rushmore to slow zombies for five minutes, which makes the orb escort far easier.

• Mannequin spawn pool — Green/Yellow backyards, Transfusion yard, Prisoner Holding, Lounge, Diner
• Orb spawn pool — Yellow House Upstairs, Green House Downstairs, or Beds window

Finish all purchases, then every player interacts with the APD Control computer together — this is the point of no return. Kill mannequins around the pyramid to fill the central canister; the APD opens, the Avogadro appears and a nuke detonates. Fill the four backup canisters in the recommended order — Storage, then Lounge, Diner, Beds — killing souls while watching the Avogadro. Each completed room electrifies and seals, so leave the instant the completion quote plays; never leave equipment or a downed player inside.

Push mechanic: back at APD Control, bullet impacts shove the Avogadro away from the shooter. Assign one pusher behind him driving him toward the APD stairs while everyone else holds fire — mixed-angle shooting sends him the wrong way. When positioned, the APD pulls him in; interact with the computer when prompted, then pick up the Elemental Shard for the ending cutscene.

• Central canister — kill mannequins around the APD pyramid
• Backup order — Storage → Lounge → Diner → Beds (exit each on the completion quote)
• Push the Avogadro into the APD → activate the computer → take the Elemental Shard
