To unlock the DIE Cyro-Emitter Wonder Wonder, you need to head to the penthouse at the top of the Nacht Der Untoten building.
Looking over the edge of the building near the green tarpaulin at the top, there is a box just to the left. Shoot this box and pick up the flask dropped in the pond area below. After collecting the flasks, look for a nearby tree covered with fungus.
You need to lure megaton zombies into this area and blow up fungus-covered trees with their radioactive attacks. Then interact with the fungus and place the flask underneath.When the flask is full, pick it up and head to the facility’s Medical Bay.Upon arriving at Medical Bay, not far from the particle accelerator door is a small chain-covered box.
Use the flask to operate the box and have the flask remove the chain. When you open the box, you will receive a DIECryo-Emitter.
To unlock the DIE Nova 5 Wonder Weapon, go to the Mezzanine Room on the top floor of the Nacht Der Untoten Building. When you reach the top, you’ll find a small golden canister sitting at a table in a small room on the edge of the building.If you cannot reach the canister on foot, use the suction power of DIE Wonder Weapon to pull the canister toward you. Now that you have a canister, head to the facility’s weapons lab and insert it into the white machine just to the right of the large blueprint hanging on the wall.After inserting the canister, kill the Plaguehound that appears near the machine. With the canister infected, pick up the canister and head to the crash site.There is a small box near the crashed plane-interacts with it and then melee attacks it. You can now receive the DIE Nova 5 from the box.
Once you have DIE Shockwave, return to the Dark Aether Portal on the ground floor of the Particle Accelerator Room, just below the Pack-A-Punch machine.
Once in Dark Ether, you need to collect a total of 3 Energy Crystals. These crystals are located at the following locations and can be collected in any order.
- Crash site:
- The energy crystal is on the ground near the entrance to the tunnel, not far from the park machine.
- Nacht Der Untoten:
- This energy crystal is located on the roof of Nacht Der Untoten, just above the stamina up machine.
- The final energy crystal is near the mystery box, not far from the road leading to the facility tunnel.
It is important to note that only one crystal can be collected at a time. This means that you need to trip the crystal three times separately.
After picking up each crystal, return to the particle accelerator room and shoot the crystal into the box on the first floor of the room. Repeat this step for the third crystal and you will receive a DIE Electrovolt variant of Wonder Weapon.
To get the Thermofasic Wonder Weapon, head to the pond and enter from the Dark Ether Portal.
When you reach Dark Ether, go to the crash site. At the crash site, there is a small box under the floating plane.
Based on the time limit, you should complete the following steps as soon as possible.
First, melee attack a small box to receive a fuse. With the fuse in hand, go to the on-site weapons lab and place the fuse in the plasma cutter opposite the park machine.
Return to the normal world and return to the pond. Look for old trucks here. Operate the green box sitting on the truck bed to find the DIE heat phase weapon.
