Juggernog is one of the most iconic perks in Call of Duty: Zombies. Once you drink it, it will give you some extra health. It is one of the most important perks available to you, especially in Black Ops Cold War due to all of the chaos. In the new Zombies Firebase Z map, there is a small Easter egg that you can complete to get the Juggernog perk for free. All you have to do is follow a few simple steps.
The first step is to activate all three of the aether reactors in order to turn on the power. Once you have done this, make you way back to your spawn area and go into the room which contains the Pack-A-Punch machine. When you are facing the Pack-A-Punch machine, look to your right and you will see some stairs. Once you go up the stairs, turn left and walk past the zombies entrance. You will notice a small hallway that is blocked off. Then, face the blocked-off hallway and aim down sight at the bunny which is placed at the end of the hallway.
Keep looking at the bunny and it will eventually float up into the air. It will proceed to fly towards you and teleport you to a new area. You will then see a pink glowing bunny which you will need to run towards and shoot. You will have to repeat the process two more times. Afterwards, you will be able to claim your reward from the glowing loot crate that will appear.
Boost your health for free with the Zombies Juggernog perk
It is a fun little Easter egg to get yourself some free loot. However, it is important to note that you can only complete this once. Therefore, if you lose your free Juggernog at any time in your Zombies match, you will have to purchase it to get it back. You can also try your luck at getting a powerful weapon by visiting the various mystery boxes around the map.
