🏰 DER EISENDRACHE — MY BROTHER’S KEEPER
1. ⚡ Turn on the power
Work your way into the castle and turn on the power. You’ll also want to activate Pack-a-Punch by teleporting its pieces from the three PaP locations.
Eventually you’ll need the Wrath of the Ancients, upgraded bows, Ragnarok DG-4, and a strong Pack-a-Punched weapon.
2. 🐉 Feed the THREE dragons
There are three stone dragon heads:
🐲 Courtyard — near the church entrance
🐲 Mission Control
🐲 Undercroft/Pyramid room
Kill zombies individually near each dragon.
The dragon eats the zombie after it dies. Wait until it finishes eating before killing the next one.
After enough zombies, the dragon crumbles.
Complete all three.
Go to the tomb near the Undercroft and collect:
🏹 WRATH OF THE ANCIENTS
3. 🏹 Upgrade your bows
There are four possible upgrades:
⚡ Storm/Lightning Bow
🐺 Wolf Bow
🔥 Fire Bow
🌑 Void Bow
Important for Solo
If you’re playing Solo on a Ranked game, you generally only need one upgraded bow for the main quest.
In co-op Ranked, you’ll need an upgraded bow for each player in the game.
⚡ LIGHTNING BOW — KREEMA’AHM LA AHMAHM
This is usually considered the easiest.
Shoot the weather vane near Death Ray with the Wrath of the Ancients.
Pick up the broken arrow.
Now shoot the three bonfires outside the map:
🔥 One beyond the courtyard/clock tower
🔥 One beyond the rocket area
🔥 One near the spawn/Double Tap side
Next, go into the Undercroft.
Wall-run across the symbols without touching the ground until you’ve activated the required symbols.
Now charge the three urns by killing zombies near them.
Once an urn is charged, use a charged bow shot beside it, then shoot its corresponding outside bonfire.
After all three bonfires are completed, return to the weather vane.
Interact with the electrical effect.
Take the reforged arrow to the Lightning chest in the Undercroft.
Place it in.
Kill zombies nearby until it’s charged.
Interact again:
⚡ STORM BOW
🐺 WOLF BOW — KREEAHOLO LU KREEMAHO
Find the four paintings around the castle.
Interact with them in the correct chronological order to tell the story of the Wolf King.
If correct, you’ll hear confirmation.
A symbol appears near the Undercroft.
Interact with it and collect the arrow.
Go to the rocket test area.
Shoot the flag/banner above the cliff.
A wolf skull drops.
Pick it up.
Return to the Undercroft and follow the spectral wolf.
It will stop at several locations.
Kill zombies near the wolf to dig up bones.
Repeat until you’ve collected everything.
Eventually the wolf leads you back underground.
Wall-run and shoot the glowing symbol.
A platform appears.
Stand on it and interact with the skeleton.
Take the reforged arrow.
Place it into the Wolf chest and charge it with zombie souls.
Collect:
🐺 WOLF BOW
🌑 VOID BOW — KREEGAKALEET LU GOSATA’AHM
Go toward the Double Tap/GobbleGum area and shoot the appropriate ceiling symbol with the Wrath of the Ancients.
Pick up the broken arrow.
Melee-kill a zombie over the purple ritual tile.
The urn begins the ritual.
You’ll need to collect six skulls hidden around the map.
Return them to the ritual room.
You’ll then need to kill Crawlers/zombies and collect the required symbols/words for the puzzle.
The demonic voice gives you clues.
Use those clues to determine the correct sequence of symbols.
Shoot the symbols in the proper order.
Once completed, obtain the reforged arrow and take it underground.
Charge it with zombie souls.
You’ll receive:
🌑 VOID BOW
🔥 FIRE BOW — KREEAHO’AHM NAL AHMAHM
This one is usually the trickiest.
Shoot the wall near the clock tower to start the quest and collect the arrow.
Wait for a rocket test.
When the test finishes and the doors reopen, quickly shoot the glowing object outside the rocket area.
Now use the Wunderspheres.
While flying through the air, shoot the three glowing ritual circles on the ground.
Once activated, stand inside each circle and kill zombies until it’s charged.
Next, shoot the corresponding fireplaces around the castle using shots originating from the charged circles.
Complete the fireplace puzzle.
Return to the Death Ray area and interact with the glowing fireball.
Take the reforged arrow underground.
Charge it with zombie souls.
Collect:
🔥 FIRE BOW
4. 🔫 Upgrade the Wrath/Bow and prepare
Make sure everyone who needs an upgraded bow has one.
You should also start obtaining the parts for:
⚡ RAGNAROK DG-4
The three pieces come from completing different map events, including the Panzer Soldat, Death Ray interactions, and the rocket-area sequence.
Build the Ragnarok at a workbench.
5. 🔵 Activate the Pyramid
Go into the Undercroft.
Stand on each of the four pressure plates surrounding the pyramid until they activate.
This turns on the low-gravity effect.
You’ll need this area for several later steps.
6. 🕰️ TELEPORT BACK IN TIME
Now we’re entering the main quest.
Shoot the four glowing wisps around the castle using an upgraded bow.
Possible wisp locations include objects such as:
📻 Radios
🕰️ Clock
🚗 Car tire
📦 Boxes/equipment
☎️ Telephone/globe-like objects around the castle
Only one is active at a time.
When you shoot the correct one, you’ll hear an audio cue.
⚠️ Don’t shoot random objects.
Hitting the wrong target can fail the sequence for that round.
After hitting all four wisps, go to the teleporter.
The teleporter should glow purple.
Everyone enters.
7. ⏳ Grab the items in the past
You’ll be transported back in time.
Watch what happens in the room.
While you’re there, collect:
🔵 The blue fuse
🧪 The canister
Also pay attention to the code Dr. Groph enters into the safe.
You’ll need that code.
You’ll automatically return to the present.
8. ⚡ Death Ray + Safe
Take the fuse to the Death Ray.
Insert it into the machine.
Switch the Death Ray control from:
DESTROY → PROTECT
Activate the Death Ray.
Now interact with the nearby computer terminals.
Enter the symbols/code you saw while traveling through time.
The safe opens.
Take the items from inside:
Two Tesla coils
9. ⚡ Install the Tesla coils
Place the two coils into the large Death Ray towers.
Switch the Death Ray back to:
DESTROY
Activate it.
This powers the next part of the quest.
10. 💻 SIMON SAYS
Now you’ll have to complete two Simon Says computer puzzles.
One is at:
🏰 Death Ray
The other is at:
🚀 Rocket Test Site
The computers show symbols in a sequence.
Memorize them and enter them back correctly.
Complete both.
11. 🚀 DEMPSEY’S ROCKET
Once the computers are completed, activate the Death Ray.
Look into the sky.
A rocket containing Ultimis Dempsey crashes into the courtyard.
Go to the crash site.
Pick up the:
🔑 GOLDEN ROD
12. 👻 Keeper ritual
Return underground.
Insert the Golden Rod into the slot near the tomb.
A Keeper appears.
Follow him.
He’ll stop at ritual circles around the map.
At each location, the circle displays an elemental color.
You need to kill zombies inside the circle using the corresponding upgraded bow.
For example:
🔵 Lightning → Storm Bow
🔴 Fire → Fire Bow
🟣 Void → Void Bow
🟢 Wolf → Wolf Bow
Continue following the Keeper and filling his circles.
13. 🪨 Keeper reaches the Pyramid
Eventually the Keeper returns underground.
After you’ve supplied enough souls, he’ll complete his ritual.
A stone tablet appears.
Pick it up.
14. ⏳ TIME TRAVEL AGAIN
You’ll need another successful wisp sequence.
Shoot the four wisps.
Enter the purple teleporter again.
Back in the past, interact with the required object/tablet location and finish the interaction.
Return to the present.
15. 👻 Finish the Keeper ritual
Bring the tablet back and place it into its required location.
Finish the remaining Keeper soul collection.
Once everything is complete, the pyramid opens the path toward the boss encounter.
⚠️ BEFORE ENTERING THE BOSS FIGHT
Don’t rush in.
Get:
🏹 Upgraded bow(s)
🔫 Pack-a-Punched weapon
⚡ Ragnarok DG-4
🛡️ Shield
❤️ Juggernog
⚡ Speed Cola/Double Tap if desired
And grab fresh ammo if possible.
Once you enter, you’re committed.
👹 FINAL BOSS — THE KEEPER
You’ll be transported into the boss arena.
The giant Keeper attacks while:
💀 Skeletons swarm you
🤖 Panzers spawn
⚡ Energy attacks fill the arena
Keep moving.
Eventually the Keeper moves into the center and becomes vulnerable.
⚡ THIS IS WHERE RAGNAROK MATTERS.
Place the Ragnarok DG-4 underneath the Keeper.
This traps/stuns him.
His chest opens.
SHOOT THE GLOWING CHEST.
Unload your strongest weapons into him.
After the damage phase ends, survive until you can repeat.
You’ll need several damage phases.
💀 PANZER PHASES
Between Keeper damage phases, Panzers enter the arena.
Prioritize them.
The upgraded bows are excellent here, especially the Storm Bow for controlling enemies.
Keep surviving until Ragnarok recharges.
Then:
Keeper center → Ragnarok underneath → Chest opens → DAMAGE
Repeat.
Eventually…
💥 KEEPER DEFEATED.
16. 🔑 Take the Summoning Key
After returning from the boss arena, collect the Summoning Key.
Take it to the computer near the clock tower/Death Ray area and insert it.
The final sequence begins.
🌕💥 THE ENDING
The characters use the Summoning Key.
The Moon is destroyed.
And Primis Richtofen finally confronts Ultimis Dempsey.
Dempsey says goodbye before Richtofen ends his Ultimis counterpart’s life, allowing his soul to enter the Summoning Key.
