Step 01: Wonder Weapon
Crafting the Jotunn Star
After turning on power, grab the admin card and use it to unlock the office before collecting parts.
Parts Required
Jotunn Star
Chain
Lower the crane near the boat and wall jump to grab the chain at the tip of the boat.
Jotunn Star
Chilly Chunks
Found on the bridge near Tyr.
Jotunn Star
Lantern
Place the Chilly Chunks on the table in the Market to spawn the Polar Zursa on the second special round. Kill it to obtain the Lantern.
Assembly
Bring all three Jotunn Star parts to the underground crypt and place them.
When all parts are placed, constellations will appear on the wall. Interact with the same constellations shown on the altar in front of you in order:
Left
Right
Behind
In Front
The weapon is not crafted at the crypt. After the constellation puzzle and the lantern step, follow Astrid through the Market and Town. There are 8-kill holdouts on the way.
Astrid leads you to the lighthouse for two platform holdouts: 8 zombies, then 10 zombies. After Round 50, the platforms time out after 15 minutes and reset.
The Jotunn Star wonder weapon is crafted in the lighthouse.
Step 02: Support Weapon
Crafting the Wunderbarrage
Parts Required
Wunderbarrage
Crowbar
Found on the bottom floor of the lighthouse. Crowbar
Wunderbarrage
Cannon Round
Inside a crate broken by the crowbar.
Wunderbarrage
Transmitter
Load the ammo into the cannon near the robot and hit it with the Jotunn Star to fire it into the robot head at spawn. Interact with the machine to receive the transmitter.
Atomkraft Core
Pincer Claw
After opening the garage with the RXCD, find the hallway with nuke symbol rooms, Room 1 = A, Room 2 = B, etc. Grab the corresponding head canisters, fill up the acid, then dump the acid on the claw.
Atomkraft Core
Uranium (x3)
- Play the Die Glocke scorestreak minigame up to tier 3 (any tier in Directed mode). The uranium drops only if it reaches tier 3
- Fish a glowing fish, it spawns an Irradiated Ravager HVT, kill it. Glowing fish only appear after the wonder weapon quest is done, at specific holes. The chance per round is n(n+1)/2 %, so it is very likely by Round 13-14. The HVT can reset up to 3 times
- Lockpick the cage in the same room as the pincer claw
Atomkraft Core
Uranium Canister
Beat the claw machine mini game, connect 7 with the charge, and leave two unconnected. The real target is a total charge of 63 to 72 on the needle, which is what connecting 7 and leaving 2 achieves. Requires all three uraniums first.
Assembly
Once you have all three parts, plug the transmitter in upstairs of Tyr's Head.
Pay attention to the lights that flash above the main console. There will be two sets of lights. For example, they might blink together once, then just the left one blinks, then a short pause, then another series.
Use both sets of lights as your amplitude and frequency in the broadcast tower.
Code Example
If your left light blinks 3 times then 5 times, and your right light blinks 4 times then 1 time, your code is 3-4, then 5-1.
Grab the remote control for the Wunderbarrage from the desk in the room next to you. Use it to blow debris off the staircase near the crafting table.
Enter the room and interact with the claw machine. You must have all three uraniums before you can interact. Solving it gives you the uranium canister.
Step 03: Upgrade
Charging the Atomkraft Core
Parts Required
Atomkraft Core
Vegvisir Meat
Obtained through main quest progression, drops after the Dravakar vs Tyr fight scene.
Atomkraft Core
Sunstone
Complete the bonfire lockdown and kill the HVT Pincer. Sunstone
Charging
Take the uranium canister to spawn and place it near the generator by Quick Revive.
Start the generator with the switch inside the building and protect it, keep turning the generator back on whenever it turns off.
With the canister fully charged, bring it to the bridge and set it on a barrel. A fight scene between Dravakar and Tyr will play out.
After the fight, the Vegvisir Meat will drop.
Step 04: Main Quest
The Bonfire Preparation
Take the Vegvisir Meat to the church where Vulture's Aid is, and place it on the bonfire.
Light the bonfire with a charged attack from the Jotunn Star.
Use a Disciple Injection to throw zombies into the fire. Throw 5 zombies in (2 in Directed mode) to trigger a lockdown.
Kill the HVT Pincer during the lockdown.
Collect the Sunstone.
Step 05: Sunstone
The Sundial
Bring the Sunstone to the other church with the sundial.
Place the stone and melee it with the Jotunn Star. Runes will spawn around the map and above the church.
Pay attention to the arrows pointing to symbols: they will have lines across them. Find the corresponding symbols 1 through 3 and shoot each with a charged shot from the Jotunn Star.
After the third symbol, an audio cue will play.
Step 06: Final Encounter
Tyr's Head
Head to Tyr's Head and start the final encounter.
