Call of Duty: Black Ops 4

This is the main Easter Egg for Alpha Omega. It will take around 90 to 120 minutes depending on teammates, map familiarity and a bit of luck, though in my opinion, this is the easiest one of Black Ops 4 so far! Keep in mind that this must be done on Normal difficulty or above.

Recommended Weapons: Any of the Ray Guns, Hellion Salvo with PHD Slider, MOG-12. Start with Strife w/ Stiletto Knife or MOG if you have them. Wraith Fire is most useful equipment but replace them with the Monkey Bombs if you get it from the box. Any Specialist will do, though level 3 Ragnaroks can revive people with full perks and the Path of Sorrow can help with a step, but are by no means required..

Recommended Perks: Stamin-Up, Bandolier Bandit, Dying Wish, Mule Kick. I also like Quick Revive and Winter’s Wail.

Recommended Elixirs: Anywhere But Here, Temporal Gift, Stock Option, Aftertaste (if solo)/Nowhere But There (if co-op). The non-classic elixirs can be helpful if you have good ones but are not required. For example Wall to Wall Clearance will make all wallbuys 10 points for you for a short period of time, saving you thousands on the Galvaknuckles.

Step 1: Activate Pack-a-Punch, then on the next round interact with Rushmore (the computer) in Operations. You'll need to save points for the Galvaknuckles so in the meantime grab all of the parts. While they’re not required for the Easter Egg, you may also want to start work on one of the Ray Guns, my favourite is the II-V.

Step 2: Once you have Galvaknuckles, find a TV with static in the Bunker, it can be in the Lounge, Beds or Diner. If you have a pen and paper, it might be useful here! Kill a nearby zombie with the Galvaknuckles to activate it. The TV will start reading 5 lots of letters followed by numbers, for example E0945, write these down. The letters correlate to certain houses and the numbers are times that you must change the clocks inside to. The buildings are:
 

• A - Yellow House (clock is by door leading to the top of the stairs)
• B - Green House (clock is by the upstairs back door)
• C - Prisoner Holding (clock is by the side door leading to Operations)
• D - Transfusion Facility (clock is to the left of the operating table)
• E - Operations (clock is to the right of the door leading to the crafting table)
• F - APD Interrogation (clock is on the left hand wall near the stairs)

If you hold interact on the clock it will go forward in 15 minute intervals, if you melee it will move forward an hour. You must do these in the order given. Once you've set all 5, interact with the clock you didn’t have to set and it will change time. Enter this time into Rushmore, then interact with him again.

Note that as you set each clock, something will become available. For Prisoner Holding, every player will be able to pick up a free Pack-a-Punched weapon from a locker by the back door. For Operations, one player will be able to pick up a regular Ray Gun Mk II from a lockbox. The other houses will unlock traps, required for Entrapment Entrepreneur (15G).

Step 3: Somewhere on the map, usually in the bunker, will be a red Nova 6 crawler. You must find him and make him follow you to the Transfusion Facility, to the blocked off stairs next to the back door. When you're done, interact with Rushmore.

Step 4: For this step you must activate Sergeant ADAM. To do so, you must find four codes around the map. The first is on a table near Rushmore and is always 7626. The second is on a table somewhere in APD Interrogations. The third is in APD Control. On the computer to the right of the door to solitary is a stack of papers, melee it to reveal the code. For the final code, retrieve a key from a box on the wall in Solitary. Head to the Yellow House, next to the upstairs back door is a desk you can interact with to find the final code. Enter these in that order on Rushmore's keypad.

Once you have unlocked ADAM, head to Storage and activate him. Now head to the stairs between the Green House and Bunker with ADAM in tow, midway up is a door. Once ADAM is near, some dialogue will occur and you'll be given a canister. Place this canister in the Transfusion Facility, next to the door leading to the Green House. Interact with Rushmore again.

Step 5: For this step, you'll need a Jumping Jack. To the left of the Teleporter Pad in the Power House is a panel, your goal is to get the Jumping Jack to shoot it with a ranged attack. If you lure the Jack to around the red car and quickly run to the panel, it should fire the bolt, which will open the panel. Now you’ll need teleporter pads, see Chug! Chug! Chug! Chug! (15G) for part locations. Place one on the pad next to the panel and place the other either next to the Brew Perk or in the Prisoner Holding backyard. You’ll need to interact with the panel, head through the teleporter, then run to Operations and interact with a similar panel to the right of the stairs in a certain time limit. If you fail, you can try again until you get it. If you have the Path of Sorrows specialist, you can take advantage of this to travel faster.

Step 6: For this step you'll need a gun with the Brain Rot repack effect. There will be three paintings with green mist coming out of them. One will be at the top of the Green House stairs, one will be in the Lounge next to the stairs leading out of the Bunker and one will be in Beds to the left of the teleporter pad. You must turn a zombie with Brain Rot near each of the paintings to reveal a code. Once you have all three, enter them all into Rushmore.

Step 7: The power will go off in the map, you must adjust 6 switches in the Bunker before you can switch it back on. They are in the following places and must be switched in the following direction:
 

• Diner - Next to the Restrooms (Up)
• Beds - Between the Diner and Generator tunnels (Up)
• Lounge - To the right of the Beds tunnel, next to a green couch (Down)
• Generators - To the left of the right hand tunnel leading to Beds (Up)
• Storage - To the left of the barrels next to the Bunker exit/Control tunnel. (Down)
• Solitary - Right next to the M1927 wallbuy (Down)

Once all of the lights on the switches are green, you can pull the original power switch to restore power, interact with Rushmore again.

Step 8: Somewhere on the map will be a mannequin spewing blue mist. All players must head to that area and interact with it to start a lockdown. Once this is over, pick up the mannequin part left over. This must be done twice more with different mannequins. Once you have three parts, head to the broken mannequin in APD Interrogation and interact with it to fix it. Now there will be an orb somewhere on the map, make sure to check behind barriers. Once you find it, follow it and defend it around the map until it enters the mannequin. You are now ready to start the boss fight.

Boss Fight:
Once you are all prepared, head down to the back room of APD Control and have everyone interact with the computer. Lots of mannequins will spawn, kill them near the near left pyramid pod to charge it. When it's done, the boss, the Avogadro will spawn. After some dialogue and events, it'll start moving. You cannot damage the boss. What you must do is move around the bunker and fill up four pods similar to the first one. First head to Storage. Once the pod stops accepting souls, grab the powerups and quickly leave the area. Once an area's pod is finished, the area will become electrified and therefore inaccessible. Next head to Lounge, then when that's finished Diner, then finally Beds. Head back to the Pyramid through Solitary, you will now be able to shoot/melee the Avogadro to push it back. You must keep shooting it, directing it to the pyramid door it originally emerged from. Once it's close enough, it'll be sucked in and you're done! All that's left is to pick up the Elemental Shard that will eventually appear.
