Perks & Their Order

It is also important to know the order in which you need to buy the perks. This is critical as whenever you go down, you lose some perks, and you need to ensure you don't lose the important perks such as JuggerNog, Quick Revive, and Stamin-Up first. These three perks should be your absolute priority.

You might also end up with a random perk from doing the side world events and objectives. If that happens, then do not worry. When you buy the perks, the random perk is always at the end. You can still buy the rest in the order you wish. When you warp, you will notice that the random perk will go at the end of the perks list.

Keep completing the objectives and side-missions to gather points and buy these perks.

Pack-A-Punch

As you progress through the rounds and objectives, make sure you constantly upgrade your pack-a-punch level of the weapon. Unlike the regular round-based survival maps, the pack-a-punch machines are randomly placed around maps in each region. You can bring up your map to find the location of the pack-a-punch machine.

Each tier upgrade costs as follows:

  • Tier 1: 5,000
  • Tier 2: 15,000
  • Tier 3: 30,000

This means you need a total of 50,000 points to fully pack-a-punch your PPSh-14.

Continue to do the objectives as stated and warp to Round 3.

Ammo Mods

The most important ammo mod in this easter egg is the Brain Rot ammo mod. There are multiple reasons for that. The first is that it allows you to turn elite zombies that can help you fight against the other zombies. You can only turn special zombies if you've upgraded your Brain Rot to tier IV. So, make sure you do that.

Another reason is when you are down in the facility during the launch key step of this easter egg. You are going to face 50+ Mimics. You are going to have a tough time dealing with these Mimics without a Brain Rot ammo mod. The Mimics are weak to Brain Rot.

Finally, during the boss fight, the zombies can be turned. There are going to be hordes of zombies and elite zombies during the boss fight. It would be advantageous to have a couple fighting by your side as you take down the Legion. The Legion boss is an upscaled version of the Tempest elite zombies. Tempest zombies are weak to Brain Rot as well. Assuming the same, the Legion final boss should also be weak to Brain Rot resulting in extra damage from your shots.

Keeping in mind all of the above points, we believe that Brain Rot is an absolute necessity for this easter egg. You can always run a shotgun as a secondary and equip a Hauer 77 with Shatter Blast ammo mod to take down elites such as Krasny Soldat and Manglers easily during the final boss fight.

Easter Egg Steps

Step 1: Maxis Radio

You can continue to do the objectives and side world events even on Round 3 to fully upgrade your weapon and buy all the perks if you haven't already by this point. However, Round 3 is where the easter egg steps begin.

Before you do anything else, we highly recommend you turn on your subtitles as they will make your life easier.

These subtitles will come in handy when we are doing the Maxis radio step. This step is exactly like the unknown signal radio easter egg, but instead of a song cassette at the end, you get a device called Beacon Listening Device.

The radios do not spawn before Round 3. These spawn on Round 3 and above in all the regions and have fixed spawn locations. If you have already done the unknown radio signals easter egg before, you will be familiar with this step. If you are unsure how the unknown radio signal easter egg steps work, follow along.

There is one base radio with three amplifiers that are placed in close proximity to the base radio. You first turn on the base radio which will play an alarm spawning and attracting several zombies towards you. The alarm will read "[FEEDBACK FEEDBACK FEEDBACK]" as subtitles.

Once it turns off, you can hear some static voice with a number in the subtitles indicating its audio. This is why it is best to have subtitles turned on. Otherwise, you will have to focus and listen to the audio itself.

Now, you need to find the three amplifiers. You can find them by hearing a static sound as you get closer to them. They are always near the base radio. You need to interact with them and set them to the same number as the base radio.

There is also a high chance for one of the amplifiers to play the alarm sound and spawn zombies. If that happens, clear them and then set the amplifier signal.

After completing all three, head back to the original base radio and interact for some points and the Beacon Listening Device.

You do not need to worry about finding all the radio and amplifier locations as we've done that for you. Below you'll find the locations in each region.
