Kill zombies and fill all four cannisters with souls until the lockdown lifts. This will initiate a lockdown and summon loads of zombies into the area. Depending on your team size, you need to press all the buttons in unison - then have one player quickly press the remaining button or buttons. Once you have a Chrysalaxe Wonder Weapon (or two for your team), travel to the Fuel Processing room and use the buttons on the four fuel tanks. Step #2: Getting The Catalyzed Crystal Shards Get melee kills after interacting with the pool to place all parts - after charging the machine with enough zombie souls, you’ll be able to claim the Wonder Weapon. Take the three parts to the Particle Accelerator Room and find the large tank of purple water behind the large cylinder. When it hits the crystal, this part will spawn. To get this part, you need to lure an Abomination boss monster near a dark crystal, then bait it into firings its laser beam attack.
