List of Contents

You must first progress through the main quest until you reach the Pack-a-Punch machine. After activating it, the next steps become available.
The next step requires you to find a hidden code involving Periodic Table elements. Head towards the T1 Mutant Research Lab / T1 Mutant Research Test Area to begin.
| 1 | Head to T1 Mutant Research Lab |
|---|---|
![]() Head to the T1 Mutant Research Lab, where you’ll find the Bioweapons Lab upstairs, locked with a code. |
|
| 2 | Check the Two Monitors |
![]() There are two static monitors on the floor. One is near the Deadshot Daiquiri and the other is in the room with the PhD Flopper. Take the first letter of the words that will appear on both monitors and combine them to form a Periodic Table element. If only one monitor is showing a word, that means the element is only one letter. In the image above, one monitor displays Yobbish, giving the letter Y. The other monitor is off, meaning Y is the only letter in the code. |
|
| 3 | Find the Element's Atomic Number |
![]() With your element, find its atomic number. You can use the periodic table in the room with the PhD Flopper to get the code. Y is element Yttrium, with atomic number 39. Note: If your two letters match more than one element (for example, R.E. could be elements Re or Er), try both codes and one of them will work. |
|
| 4 | Enter the Code to the Bioweapons Lab |
![]() The element’s atomic number will be the code for the Bioweapons Lab door. If it has fewer than three digits, add leading zeroes (for example, 007 for atomic number 7). With Yttrium, the code is 039. |

Inside the lab, lead three Vermin to get absorbed by the Cyst in the petri dish. Do not kill the vermin, or they will not be harvested correctly.
After leading enough vermin, lead three Zombies to be absorbed in the same manner. Once done, grab the Cyst for the next step.

Drop down to the T1 Quantum Computing Core floor to charge the Cyst by the large white flowers. You will see the amount of charge left to absorb on the left side of the screen.

With the Cyst fully charged, head towards the T2 Dark Entity Containment floor and activate the four monitors that display Initiate Power Surge. After activating all four in quick succession, Uber Klaus will spawn.
Do not kill Uber Klaus just yet. You must lead it to the electrical floor near the Forsaken correctly to trigger the actual boss fight required to obtain the Wonder Weapon.
| 1 | Destroy Uber Klaus' Shoulder Pads |
|---|---|
![]() Destroy the two electric shoulder pads that Uber Klaus is wearing. |
|
| 2 | Lead Uber Klaus to the Electric Floor |
![]() With Uber Klaus' shield disabled, bait him to step on the charged electric floor by the Forsaken robot. |

Uber Klaus transforms into the Forsaken for a tough boss fight. The boss has two phases: the first in its original armored form, and the second in its core form.
Stay mobile throughout the fight to avoid its huge damage. In the first phase, aim for the weak spots on its shoulder pads, and in the second phase, target the core on its torso.

The defeated boss will leave behind a blue orb. Interact with it to turn the orb orange, and it leaves behind the Gorgofex after it explodes.

The Gorgofex functions similarly to a Ray Gun, and you can charge shots for huge burst damage. Its blasts create an AoE effect that deals damage to zombies near the impact point.
