I'd like to say before I write this, I might get a step or two wrong, so if I do please let me know!


Step 1: You need to go to the fishing hut and as soon as you enter, turn right and pick up the weapon barrel from the shelf.

Step 2: Outside of the comm room, in the water, you should see a little device that you can place the weapon barrel into.

Step 3: Swap the round, and the device will now become a soul box, fill the said soul box until the yellow lightning goes away, and pick the weapon barrel up from the device.

Step 4: Walk into the comm room and take the door on the left, as soon as you enter turn right and you should see something with a charged vacuum tube it in, grab the vacuum tube and go into the next room. Enter that room and on the desk their should be an electrical fuse, grab the fuse.

Step 5: Go into the storage hut and you will see a trap which you need to activate, activate the trap and after a few seconds it will turn off, meaning you have to fix it. Go to the trap, and hold the interact button. This will put that fuse you picked up earlier into the trap. Activate the trap once again and get around 20 kills with the trap. You can tell once you're finished when the fuse on the Wunderwaffe build table starts to spark.

Step 6: As you survive and progress through the rounds, you will eventually start to see zombies with a purple mist around them. These zombies drop purple electric puddles every now and then. You want these electric puddles to touch the electric beam until the fuse on the table next to it is charged.


Once it is fully charged you can pick up the charged tube off the table and craft the Wunderwaffe in the storage hut!
