Spectral Shield
Collect the parts for the Spectral Shield:
- Afterlife Essence:
- Michigan Avenue
- Library
- Times Square
- Door:
- Citadel Tunnels
- Citadel Tunnels
- China Alley
- Key: drops from Brutus the first time he is killed
Build the Spectral Shield at any of the Build Tables around the map.
Step 1
Activate Pack-A-Punch
Use the Shield Blast on the Power Box on the Roof to spawn in Pack-A-Punch.
Build
Hell's Retriever
Feed 3 Dogs around the map by killing zombies near them, one by one:
- New Industries
- Cellblock 2nd Floor
- Eagle Plaza
After all 3 Dogs are fed, take the Fast Travel to Warden's House from the Showers (either direction). Halfway through the Fast Travel, you can grab the Hell's Retriever.
Note
You need both the Hell's Retriever and the Spectral Shield to obtain the Spoon.
Build
The Spoon
In the Warden's Office, stand at the Fireplace and look at the 3 pillars in the room through your Shield to reveal 3 numbers. Note these down in order from closest to furthest.
Shield Blast the Number Pad in the Citadel Tunnels, then input those 3 numbers in that order.
Shock the Voltmeter at the Docks to raise a fishing net with a crane. Throw your Hell's Retriever at the net to drop the Spoon from it.
Pick up the Spoon on a box on the Docks.
Note
You need the Spoon for the next step.
Step 2-3
Warden's House Wall & Brutus
Using the Spoon, melee the wall upstairs in the Warden's House.
Get Brutus to do a slam attack next to the wall you just scratched. This opens the wall.
Tip
Brutus will naturally slam after round 20, or you can force it: throw a Monkey Bomb at the wall and lure Brutus near it so he slams the Monkey Bomb.
Step 4-5
Warden's Ritual Room & Kronorium
In the newly opened Warden's Ritual Room, hit the lever next to the chair, then grab the Red Stone on a table in the room.
Place this Red Stone on the map in Richtofen's Laboratory.
Interact with the Kronorium on the ground in Richtofen's Lab to spawn in a bird.
Step 6
Hunting the Bird (x3)
Find the bird by looking through your Spectral Shield: while looking through it, you can hear and see the bird.
Once found, Shield Blast it. The bird respawns and switches spots each round. Repeat this 2 more times (3 total).
Tip
At the start of each round, go to the top of Gondola and look down toward the Docks through your shield. You'll see the bird spawn in and quickly dart to its location along the Gondola's path. This can help narrow down where it went.
Note
There are 39 possible spawn locations for the bird. Tap a number below to see that spot.

Step 7
The 4th Bird (Special)
After Shield Blasting the bird 3 times, the 4th time works differently:
- You won't be able to see or hear the bird through the shield like before.
- Instead, you'll see an occasional shimmer and hear a man crying when looking directly at where the bird is.
Locate where the sound is coming from. Its possible locations are limited during this step and can't go much past the Citadel Tunnels.
Enter 872 into the Citadel Tunnel Number Pad to spawn a Zombie Blood.
Use the Zombie Blood, then go back to where the sound was. Quickly look through your shield at the bird, then. While still holding your shield . throw your Hell's Retriever at the Kronorium it's sitting on.
This drops the Kronorium on the ground. Pick it up.
Tip
It's recommended to use the Temporal Gift elixir to make the Zombie Blood last longer.
Warning
Do NOT Shield Blast the bird this time. That will fail the step. In Co-Op, make sure no other player is near you or the bird, or the step could glitch and fail.
Step 8
The 5 Challenges
Place the Kronorium on the Warden's body in the Warden's Ritual Room. It will flip to a page. Using the Spectral Shield, you'll see 3 numbers to input into the Citadel Tunnel Number Pad.
This starts 1 of 5 challenges in random order. To find which one, look at the lighthouse by the Warden's House: it will shine toward the challenge area. At that area, you'll see the red lighthouse light shining into a portal.
Shield Blast the portal to start the challenge.
After each challenge, a Red Stone drops. Pick it up and place it in the map in Richtofen's Lab (can be done any time).
To start (or restart) the next challenge, get a new set of numbers from the Kronorium and enter them into the Citadel Tunnel Number Pad again.
Michigan Avenue Challenge:
- Kill a zombie in the Cafeteria. A ghost appears, visible through the Spectral Shield. Shield Blast it.
- Defend the ghost as it makes its way into the portal in Michigan Avenue, leaving a Red Stone on the ground.
Showers Challenge:
- A ghost will be in the corner playing a Banjo. Take the Banjo and stand in the circle that randomly moves around the Showers.
- Get kills inside the circle to charge the Banjo. Once the carrier starts taking damage, give it back to the ghost so he can retune it.
- Repeat this until, when you give it back, he disappears and leaves a Red Stone on the ground.
Power House Challenge:
- In Building 64, interact with a sparking generator to start Simon Says with the generators.
- Complete 5 rounds of Simon Says. After round 5, 3 generators will light up. Remember the symbols on the small drawings attached to those 3 generators.
- Pick up the Punch Card from a shelf in the middle of the room.
- In Model Industries, place the Punch Card into the computer. The monitors light up. Interact with the 3 that have the corresponding symbols from your Simon Says result.
- Each monitor gives you a new symbol. Remember all 3.
- In the Power House, you'll see a ghost walking by the Power Switches (which have symbols on them). Shield Blast the ghost the first time it reaches for each of your 3 corresponding levers, 3 times total.
- The 3rd switch makes the ghost disappear, dropping a Red Stone.
Docks Challenge:
- In the Sally Port, there's a Telegraph that needs Morse Code input. You can guess, or visit 3 separate buoy locations and look through your Spectral Shield to see the flashing Morse code:
- Buoy 1: to the left of the top Gondola location, in the water
- Buoy 2: at the end/prison side of the catwalk to the right, in the water
- Buoy 3: in spawn, through an upstairs window, in the water
- Hold the interact button (~3 seconds) for a long signal, tap for a short signal.
- Once entered correctly, your character will say a quote and the Telegraph can no longer be interacted with.
- Kill a zombie in the long hallway in the Infirmary: a ghost appears, visible through the Spectral Shield. Shield Blast it.
- Interact with the ghost to make it follow a player, then kill zombies near it to charge it and keep it walking.
- Take it on the Gondola down to the Docks, into the portal, to make it disappear and drop a Red Stone.
New Industries Challenge:
- Kill a zombie in the Library. A ghost appears, visible through the Spectral Shield. Shield Blast it.
- The ghost becomes visible without the shield. Use the Shield's key to suck the life out of it. It turns more red as you make progress.
- Body-block the ghost to slow its walking. Only one player at a time can use their key on it.
- After a while, the ghost becomes invisible again and needs another Shield Blast.
- Once red enough, the ghost raises its arms and walks faster. You can no longer use the key on it.
- When it gets close to New Industries, use the trap there to kill it as it walks through. Done correctly, it disappears and drops a Red Stone.
Step 9
The Summoning Key
After completing all 5 challenges and placing all 5 Red Stones into the map in Richtofen's Lab, place the Summoning Key on the Warden's body in the Warden's Ritual Room.
Result
This starts a cutscene and you'll be locked in a cell.
Step 10
Escape
After the bird frees you, pick up your weapons from the sack near the stairs.
Make your way back to Richtofen's Lab. After the Warden is taken away by the mobsters, grab the final Red Stone dropped where he was and place it into the map. This opens a hidden wall.
Final Steps
Boss Fight
Enter the boss fight by going up the newly opened stairs downstairs in Richtofen's Lab.
During the fight, the arena will eventually turn red and start damaging you. Find the safe spot that won't damage you, then break 3 orbs inside it.
After breaking the 3 orbs, Shield Blast the top of the Machine in the middle.
Repeat this 2 more times (3 total).
After the 3rd time, whoever is playing Richtofen needs to get into the chair on the machine (if no one is Richtofen, a bot will do it).
Richtofen gets a cutscene and ends up at the bottom of the lab. Make your way back up the stairs into the arena to end the boss fight.
