The Annihilator, a high-caliber revolver from the multiplayer mode of Black Ops 3, can also be unlocked for Zombies in The Giant map. It occupies your special weapon slot and is an essentially one-shot hand cannon. You are going to have fun blasting zombies with this secret weapon.
The Annihilator requires you to complete the Paradoxical Prologue, also known as the revised Fly Trap easter egg. The process involves getting an upgraded weapon from the Pack-a-Punch Machine, using it to activate a console, and then finding three hidden items around The Giant.
How to get the Annihilator in The Giant
Your first step in finding the Annihilator in BO3 Zombies in The Giant will be to turn on the Power Switch to power the Pack-a-Punch and the teleporters. The switch is in the courtyard attached to a large generator.
Now you need to activate (link) the three teleporters to unlock the Pack-a-Punch machine. PAP your weapon, preferably a sniper, since you will be shooting items from afar.
After getting the upgraded weapon, head to the left of the starting area towards the red-bricked wall, opposite the animal testing lab entrance. Aim through the grill and shoot the control panel in the distance. This will trigger an audio log of Maxis and you will see some green orbs flying away from the panel.
Now comes the part where you must find three carefully hidden items around the map to unlock the Annihilator. You just need to shoot the items to get them. Do note that you can find them in any specific order.
Item #1 Location (Monkey)
The first item is a cymbal monkey that you can find inside the furnace under Teleporter A. The furnace will be unlit and very dark, so you might not be able to see the monkey clearly.
What you need to do is aim your weapon toward the right corner of the furnace and fire. You will hear a confirmation dialogue from Maxis when you get the first item for the Annihilator.
Item #2 Location (Teddy Bear)
The second item is a teddy bear that is located close to the area where you turned on the power in The Giant. Head over there and look left of the power switch. The teddy bear will be on top of the fire escape of the building outside the map. You will have to aim over the fence to get the item.
Item #3 Location (Teddy Bear)
The last hidden item to unlock the Annihilator in BO3 Zombies is also a teddy bear. Head to Teleporter B and check the large cylindrical vat as shown in the image above. The teddy bear is submerged in water, so you will have to jump to be able to shoot it.
After shooting the last item, you will hear some more dialogue from Maxis. The Annihilator can now be collected from the furnace within the hanger.
How to recharge the Annihilator in BO3 Zombies
The Annihilator has only 18 rounds. Once you use up all of the ammo, you need to put the weapon away so that it can recharge. To recharge the Annihilator, you only have to kill zombies using your primary and secondary weapons. Once the weapon is ready, press both of your controller bumpers to equip it again.
There is also a glitch that sometimes occurs when the player is downed and has the Annihilator in his inventory; the player loses a gun and all their points start being deducted a thousand or two at a time. This is because the game’s anti-cheat falsely calculates the player as having too many weapons.
