How To Get Alistair’s Annihilator – Dead of the Night Alistair’s Annihilator Guide Before you get Alistair’s Annihilator, you need to ensure you’ve already unlocked the Chaos Theory of the Alistair’s Folly wonder weapon. Done that? Then let’s get cracking. Call of Duty: Black Ops 4 Zombies – Dead of the Night Alistair’s Annihilator • TL;DR Games • Fair UseFirst, you need to head through the Cemetery and up to the Mausoleum. There are eight lamps around the front of the Mausoleum; four at the top and four at the bottom of each set of stairs. Some will already be lit yellow, but one of them will be glowing with an orange tint. Shoot the orange one with the Chaos Theory. It will go out, and another one will light up orange. Continue shooting all the orange lamps until a bat comes flying out of one of them. Shoot the bat with the Chaos Theory, and it will drop the Bat Chaos Material. Next, you need to kill four Vampires with the charged shot from the Chaos Theory. Capture four Vampires in the Tornado effect then when they die, they’ll drop Bile. Pick up four piles of Bile then look for the glowing red tomb in the Cemetery. Interact with it to spawn a Crimson Nosferatu. Kill the Crimson Nosferatu, and it will drop the Nosferatu Chaos Material. For the final piece of the Alistair’s Annihilator upgrade, head to the Forest. There are multiple mounds of dirt with glowing mushrooms on top. As zombies get close to these mounds, shoot them with a charged shot from Chaos Theory, and they will gain a green cloud around them. This will cause them to start digging up the mounds of dirt. For the first few mounds they won’t find anything, but eventually, the zombies will dig up the final part you need for Alistair’s Annihilator. With all three parts, head to the Greenhouse Laboratory and place the Bat Chaos Material in the machine, then the Nosferatu Chaos Material in and collect both Prima Materia that it produces. With all of that, you can use the other crafting bench in the Greenhouse Laboratory to create Alistair’s Annihilator.
