Step 1-3
The Monolith & Cypher Wheels
Kill Boom Schreiers next to the Monolith at Doctor's Quarters Exterior to remove the vines covering it.
Obtain 3 Cypher Wheel parts:
- Dormitory, on a table
- Doctor's Quarters, in the side room
- Dig Site, on a table in front of Pack-a-Punch
Place the Cypher Wheels on the Monolith.
Step 4-5
Symbol Papers & the Monolith Code
Find 3 pieces of paper with symbols on them:
- Excavation Room, on a table under some papers (shoot the papers off the table)
- Dig Site, on the crafting table
- Comm Room, on a table
Use a translation cheat sheet to convert each Kanji symbol into a different symbol, then input those 3 symbols into the Monolith — they go on the top 3 middle lines.
Note
You'll need to build or obtain the Wunderwaffe DG-2 for the next step — see below.
Build
Wunderwaffe DG-2
Obtain 3 Vacuum Tubes and 1 Weapon Barrel, in any order.
Weapon Barrel + Vacuum Tube (Comm Room):
- Pick up the Weapon Barrel from a shelf in the Fishing Hut.
- Place the Weapon Barrel in the Radio Tower outside the Comm Room.
- End the current round. At the start of the next round, lightning strikes the Radio Tower and starts a defense — defend the Radio Tower.
- After defending it, pick up a Vacuum Tube from the radio in the Comm Room.
- Pick up the Weapon Barrel from the Radio Tower.
Vacuum Tube (Storage Hut):
- Pick up the Electrical Fuse from the table in the Comm Room.
- Activate the Trap in the Storage Hut.
- Once the trap stops, a fuse box next to it opens — insert the Electrical Fuse into it.
- Activate the trap and get kills with it to charge the Vacuum Tube. A quote plays when it's done.
Vacuum Tube (Excavation Room):
- Get a Zaballa to use her attack 5 times on the Tesla Coil in the Excavation Room.
- Pick up the Vacuum Tube on the table near the Tesla Coil.
Build the Wunderwaffe DG-2 on the build table in the Storage Hut.
Tip
You can check how many Vacuum Tubes and Weapon Barrels you currently have on the build table in the Storage Hut.
Step 7
First Lockdown: Blue Mist Zombies
After successfully entering the code on the Monolith, interact with a stone in the water near the Monolith.
This starts a timed lockdown — kill zombies surrounded by blue mist using the Wunderwaffe DG-2.
Note
These zombies are stronger and faster than normal. The number of blue mist zombies you need to kill depends on how many players are in the game.
Step 8-13
Demonic Fountain & Mirror Pieces
Use the Flogger in the Flogger Courtyard to fill the empty Demonic Fountain.
Drink from the fountain to enter a "Zombie Blood" state, then look for a red orb to find a piece of mirror.
Go to the War Room and check the map for an X — this leads to a second mirror piece, which should be shot down from a ceiling.
Go to the Dig Site and place both mirror pieces on the central altar to create the relic.
Every player interacts with a blue orb around the central altar.
This spawns a blue orb that moves somewhere on the map. Shoot it to bring it back to the Dig Site.
Tip
You can follow the orb as it leaves to find it more easily.
Final Steps
The Relic & the Echo
Once back at the Dig Site, interact with a stone to trigger another lockdown — kill zombies shrouded in blue mist with the Wunderwaffe DG-2.
This spawns an Echo that must be eliminated. It works similarly to Zaballa, but each phase spawns different enemies:
- Phase 1 — Zombies
- Phase 2 — Boom Schreier
- Phase 3 — Sturmkrieger
Once the Echo is killed, a short cutscene plays, and the relic becomes available to pick up.
