Step 01. Power & Pack-a-Punch

Powering the Map

Follow the on-screen guides to locate the two parts needed for the organ:

Machina Astralis
The Luminarium

Insert both parts into the organ, then protect it as it powers on and activates Pack-a-Punch.

Step 02. O.S.C.A.R

Three Traps

Kill O.S.C.A.R using three different traps around the map. Complete all three in any order. After the third trap, O.S.C.A.R will drop the wonder weapon.

Telescope

Find a valve spitting steam and shoot five in a row to power on the telescope. Align the telescope with the sun: a laser will project onto the screen. Kill O.S.C.A.R in the trap.

Tesla Coil

Shoot the hood of Ol' Tessie with a packed weapon. A car battery will shoot out of the hood. Shoot a blinking lamppost somewhere on the map to collect the wires. Shoot a drone from off of O.S.C.A.R and collect the damaged drone. Take the parts to the trap in the Luminarium. Starting the trap with O.S.C.A.R nearby triggers a lockdown to drain his power.

Rocketship

Using Cryo Freeze, shoot the purple aether crystals around the map. Once you have three, kill Klaus with the rocket engine near Speed Cola.

Step 03. 3-Digit Code

Planet Cipher

Follow O.S.C.A.R as he patrols the map. He will begin playing audio logs. When he reaches Execution Twenty, Thurston will begin saying planet names.

Listen closely and translate the planet names into numbers using the key below, then insert the three-digit code into the box in the PAP room.

An elevator will drop down containing a Cryo Key.

Mercury

Venus

Earth

Mars

Jupiter

Saturn

Uranus

Neptune

second

third

Step 04. The Brain

Thurston's Brain

Take the Cryo Key to the cryogenic chamber in the bar area.

Grab a saw from a case in the museum and use it to saw the brain out of Thurston.

Take the brain to the container near Juggernog and swap the brains, triggering a lockdown.

After the lockdown, take the new brain downstairs by the library and place it.

Step 05. Book Step

The Library Busts

Once the brain is placed, pay attention to Thurston's reading list that flashes on the screen. The book names will be found in the library.

There are three busts in the library. Count how many books are near each bust. You can turn each head up to two times, matching the number of books closest to it.

Right of entrance

turn(s)

The Musica Universalis

The Black Veil

The Moon Directive

Across from entrance

turn(s)

Ash and Bone

Echoes of Andromeda

The Unknowable Void

Lower level corner

turn(s)

Pyramids of Cydonia

Silence at Singularity

Witchlight Codex

Once all three are turned correctly, a door will open up the ladder. Climb the ladder and grab the Neptune planet.

Step 06. Portal

Stabilizing the Portal

Go to the telescope in the PAP room and find the coordinates for Mars. Insert those numbers into the device above the brain to open it.

Place the Neptune planet on the missing planet slot.

Find the three papers around the map showing where to place the three movable planets:

Mars
Neptune
Saturn

Move the planets to their correct spots, then interact with the brain to trigger another lockdown. An O.S.C.A.R will spawn. Destroy the drones as the portal stabilizes.

Step 07. Mars

The Scarab Beetle

Place the brain in the main contraption and interact with it to trigger a noise.

Look outside the map and shoot four towers from farthest to closest to attract a scarab beetle. Then hit the middle tower above the portal.

When able, jump to collect the beetle and place it in the device at the back corner of Mars.

Take the wonder weapon and shoot the metal prongs coming out of the pillars.

Return to the organ, interact with it, and memorize the order of symbols that appear.

Note

The symbols on the pillars in Mars are always in the same fixed positions The organ sequence changes each game, and one slot will display as static. Check all five to find it. Tap the symbols below in the order they appear on the organ to build your sequence.

Static

Your sequence

Interact with the same symbols on the pillars in Mars in the same order they appeared on the organ.

Interact with the brain to start the boss fight.

Step 08. Boss Fight

Four Phases

Soul Boxes

Fill up the soul box, then interact with the brain to shoot the boss in the sky. DO THIS A TOTAL OF THREE TIMES.

Crit Phase

Spam her with the wonder weapon until crit spots open up, then spam those with your secondary.

III

Crit Phase

Repeat. Wonder weapon to open crit spots, secondary weapon to damage them.

Final Phase

Same pattern. Keep pressure on her with the wonder weapon and secondary until the fight ends.

Side Easter Egg

Echoes of the Damned

Note

You must be playing as Nikolai Belinski to complete this side quest.

Travel to the lower part of Abyssal Rim and throw a Molotov Cocktail on the ground near the Ammo Cache. This creates fiery footprints forming a trail. Throw additional Molotov Cocktails and follow the footprints until they reach an inaccessible cave.

Interact with the toy near the cave to trigger a cutscene.

After the cutscene, you'll be teleported into the cave. Travel through it until you find an altar. Interacting with the altar spawns Ravagers . kill all of them until another cutscene plays.

You'll be returned to the map. Loot drops on the ground including a Molotov Cocktail and a Legendary Echo 12. Completing the side quest also rewards the "Echoes of the Damned" Dark Ops Calling Card.

Side Easter Egg

The Five Skulls

Requirement

Get a Pack-a-Punched Weapon before starting.

Find 5 skulls around the map and shoot each one to light the eye sockets, then interact to pick them up:

In the courtyard between Crash Site and The Luminarium
In one of the displays in Museum Infinitum
In a zombie spawn hole next to the Ammo Cache in Stargazer's Courtyard
In a display case in Machina Astralis, on the left side when coming from Stargazer's Courtyard
In a corner behind the brick wall in The Veilwalk, on the right side when coming from Archive of Orbis

Once all five are collected, place them on the cabinet with the large mirror in Machina Astralis.

All the skulls' eye sockets will shine and activate a Simon Says mini-game: shoot the skulls in the correct order.

If done correctly, all the skulls will float and merge into a Random Perk Power-Up.

Side Easter Egg

"Bongo" The Friendly Ravager

When defeating O.S.C.A.R., it will drop a toy robot called "Shiny Trinket", which replaces your Tactical when picked up.

Find a white dot on the minimap, located outside the playable area, usually where zombies spawn.

Travel to that location and find a green-eyed Ravager. Throw the Shiny Trinket at it. The Ravager will eat it and hide away.

Repeat the process two more times.

On the third time, the Ravager will jump into the map as "Bongo" and play with cymbals before attacking enemies for a few rounds.

Side Easter Egg

Gramophones Challenges

Reward

Free Mystery Perks. Three gramophones can be found around the map. Each needs a corresponding vinyl record. While the record plays, complete the listed challenge.

Archive of Orbis (near Stamin-Up): the record is inside a wooden box on the middle floor of Machina Astralis. While the song plays, kill 5 zombies with equipment. Once the music stops, Equipment and a Mystery Perk can drop.

The Luminarium (near the Mr. Peeks headphone): the record is at the top of a bookshelf, next to one of the grandfather clocks. While the song plays, kill 15 zombies with Field Upgrades. Once the music stops, Essence and a Mystery Perk can drop.

Museum Infinitum (near Speed Cola): the record is on the capital of the wooden pillar above a zombie window. While the song plays, kill 5 zombies with melee weapons. Once the music stops, Salvage and a Mystery Perk can drop.

Side Easter Egg

The Twins

Reward

A free Cryo Freeze Ammo Mod on first encounter, plus loot every round the Twins reappear.

During a special round, travel to Museum Infinitum and interact with the left-most display cabinet beneath the painting of a mansion/castle.

During the next rounds, weird noises will play from one of the displays in the museum. One per round, four times in total. Interact with each display.

If done correctly, the ghost twins will appear somewhere around the map in one of three states . dancing (plays music), drawing with chalk on the ground, or standing holding hands. They can appear at:

Crash Site: behind Ol' Tessie
The Luminarium: inside the Stellar Dissector, or in a corner outside on the Abyssal Rim side
Abyssal Rim: next to Wisp Tea
Observatory Dome: in a corner near the X9 Maverick wall-buy
The Veilwalk: next to the door leading to Observatory Dome
Machina Astralis: on the upper floor, or in a corner near the door leading to Scholar's Way
Museum Infinitum: in a corner near the door leading to Scholar's Way

Once you find them, the Twins will disappear, leaving loot behind. Including Salvage, Equipment, and a free Cryo Freeze Ammo Mod the first time. They reappear every subsequent round with additional loot.

Side Easter Egg

Time Dilation

Rapidly melee 5 grandfather clocks found around the map:

One in The Luminarium, next to the bookshelves
One in Museum Infinitum, near Speed Cola
Two in Machina Astralis: one on the bottom floor, one on the middle floor
One in Archive of Orbis, next to Stamin-Up

If done correctly, all enemies will move slowly for 60 seconds. This can be repeated once per round.

Side Easter Egg

Wisp Orbs

Reward

A free Ray Gun.

There are 9 lanterns against walls around the map:

Two in Crash Site
Three in the courtyard in front of The Luminarium
Two in the back of The Luminarium
Two in Scholar's Way

Find the lantern shining with a white wisp and aim at it to obtain the wisp. It will orbit around you. Your melee button throws the wisp before it comes back to you. Thrown at zombies, it usually kills 1–2 zombies. Killing zombies with the wisp gives no Essence.

To upgrade the wisp, place it inside all 9 lanterns by throwing it and getting it back by aiming at the lantern.

Once the wisp is in the last lantern, pass the round. If done correctly, the wisp turns yellow/orange and becomes available from any lantern. You can collect up to 5 wisps at a time, each upgraded wisp killing about 5 zombies.

Starting at Round 16, a rocket from Ashes of the Damned floats in front of Saturn. Hit it by throwing an upgraded wisp. If done correctly, the wisp comes back and drops a Ray Gun.

Aiming at the rocket long enough plays "Once In A Blown Up Moon" by Brian Tuey. The same music that plays after the Zarya Cosmodrome Ritual in Ashes of the Damned, based on the launch countdown track from Black Ops III's Der Eisendrache.

Side Easter Egg

DG-2 Turret Upgrade

Near the Wisp Tea machine, locate an asteroid nearby. Throw a grenade at the asteroid so its explosion knocks the asteroid closer to you.

Sprint and wall jump to the left side of the asteroid. If done correctly, you'll float into space and travel back to Crash Site. As you travel, the DG-2 Turret will spawn. Interact with it as you pass to grab it. A new mix of "Pareidolia" by Brian Tuey plays during the trip.

Once back at Crash Site, install the turret onto Ol' Tessie. It can be used freely and is effective against O.S.C.A.R.

Side Easter Egg
