The Wonder Weapon, known as the Beamsmasher, is essential to completing the Easter egg.

You can obtain it in two ways: by crafting it or through the Mystery Box. Using the Mystery Box, you have the highest chance (50%) of obtaining it if you use the “Wunderbar” gum. From the box, you’ll either get the Ray Gun or the Beamsmasher.

To craft the Wonder Weapon, you’ll need three parts:

• EMF Pendant
• Multiphasic Resonator
• AMP Ammo

For the first part, the lab needs to be opened. Someone on your team must equip the “Dead Wire” ammo mod. Next, activate the lift that the PaP is on to ascend.

On the way up, the person with Dead Wire must shoot three power boxes.

The first power box is located in a window across from the PaP. Once the first box is shot, turn right to see another power box on the wall. After shooting it, turn right again and shoot the third power box.

You’ll now notice the electricity flowing up through the building’s wiring. Exit the lift through the doorway on the right of the PaP, then go left up the stairs, past the pool table, and down the next staircase. At this point, you’ll see a power box above the generators. Shoot this power box as well.

Next, exit the room on the side where the generator is located. Right next to the blue door, you’ll find the final power box. Shoot this one to complete the sequence.

The next part, the Multiphasic Resonator, can be found at the Sea Tower.

Now, three laptops need to be activated. They are located in the following positions:

• Docks
  • 

• Storage Area
  • 

• Communication Room
  • 

Activate these laptops in any order. Once they are activated, return to the lab. On the table, you’ll find a computer with the black knob. Interact with this to place the Resonator. Then, interact with it again to start using the knobs.

You will now notice three notes with the letters x, y, and z, each featuring different symbols.

This is where your brainpower and mathematical skills come into play. You can attempt to solve the equations on your own or purchase the solution from Peck for 5,000 Essence.

In the room, there are also two whiteboards. On one, you will see the symbols from the notes, while on the other, you will find the three mathematical equations that need to be solved:

To find the values of the corresponding letters, locate the symbol on the whiteboard.

Take the number from the row label (left side of the table) where the corresponding symbol is found. The second number is from the column label (bottom of the table). This will give you the corresponding value for each letter (x, y, z), and you will need to do this for all three.

IMPORTANT: The values change with each round.

In our example, the values were as follows:

• X = 10
• Y = 20
• Z = 22

With these values, you can solve the three equations from the other whiteboard:

1. 2X + 11
   Take double the value of X (20), add 11, and you get 31.
2. (2Z + Y) – 5
   Take double the value of Z (44), add Y (20) for a subtotal of 64, then subtract 5 to get 59.
3. (Y + Z) – X
   Add Y (20) and Z (22) for a subtotal of 42, then subtract X (10) to get 32.

Now you have the required code: 31, 59, & 32. Enter this code into the machine and confirm it. If you entered it correctly, the numbers will light up green, and the screen will display a map with a moving target indicator.

Now, you need to play until Round 9 or until the next wave, if you are already past Round 9. Once that’s done, interact with the machine again, and it will show you a location on the map. Also, pick up the Resonator again, as you will need it for the next step.

Now, take a boat to Castle Rock Island, where you will see a blue orb. Approach it and interact with it to activate an encounter. During this encounter, the orb will hit certain zombies with a beam.

You can identify these zombies by a colored shimmer around them. When you kill them, they will drop a sphere. You need to pick up this sphere and bring it to the large main orb by walking through it.

Do this as many times as the number of players in your team.

Once you’ve brought enough spheres to the main orb, it will fly to a different location. You can now pick up the Resonator again and head to the next island.

You need to complete three spheres in total (Blue, Yellow, and Purple), which are located on the following islands:

• Castle Rock Island (Blue)
• Crab Island (Green)
• Temple Island (Purple)

After completing all three spheres, you will be able to pick up the last part: the AMP Ammo.

Now, head back to the lab and use the workbench to assemble the Wonder Weapon.
