Guide: How to Obtain the Gorgofex Wonder Weapon in Reckoning (Black Ops 6 Zombies)

1. Power Up and Unlock Pack-a-Punch

Your adventure begins by restoring power on the Reckoning map—this action unlocks access to Pack-a-Punch and opens up the path to pursuing the Wonder Weapon.

2. Solve the Periodic Table Cipher

Head to the T1 Mutant Research Lab, near the Deadshot Daiquiri perk machine. Look for a monitor displaying static—the static will resolve into a random word. Jot down its first letter.
Next, move to the T1 Mutant Research Test Area, where another static monitor awaits next to the cryo tube. Retrieve the first letter of that word too.

Match your two letters on the nearby Periodic Table to identify an element and note its atomic number. Use that number—padded to three digits if necessary (e.g., “085”)—as your code.

3. Access the Bioweapons Lab and Harvest the Cyst

With your code, go upstairs in the Test Area to find a keypad. Enter your code to unlock the T1 Bioweapons Lab. Inside you'll find a sealed incubator with a cyst. Defeat nearby zombies and vermin until the cyst absorbs enough energy—about six kills—and you’ll know it's ready when you see a golden orb and hear a cue. Interact to collect it.

4. Charge the Cyst with Mushrooms

Carry the cyst to the T1 Quantum Computing Core. Parachute down into the mushroom-filled room, and the cyst will automatically start absorbing energy from three glowing mushrooms. Be aware—you're vulnerable while charging it.

5. Initiate the Power Surge and Spawn UberKlaus

Head to the Dark Entity Containment area. Locate a terminal labeled “Initiate Power Surge” (in green text), interact with it, and then quickly move to the next one—this must be repeated four times consecutively, or you’ll have to start the sequence anew.

Once successful, the mech-suited mini-boss UberKlaus appears. Instead of killing him outright:

• Shoot the purple glowing armor on his shoulders to expose his vulnerable core.

• Lure him onto an electrified area to stun him.

• Be cautious: in phase two, he sheds the mech and attacks directly while Klaus drones circle you. Defeat him to unlock the Gorgofex 

6. Claim the Gorgofex

A purple orb spawns—grab it, and you'll acquire the Gorgofex Wonder Weapon. Note: the base version cannot be Pack-a-Punched unless obtained from the Mystery Box or with Wonderbar gobblegum, which might yield other weapons instead 

Alternate Method: Via Mystery Box or Wonderbar Gobblegum

If luck is on your side, you can bypass the Easter egg entirely—both the Mystery Box and the Wonderbar gobblegum can award you the Gorgofex early. However, this is unreliable, and the Wonderbar gum does not guarantee the Gorgofex—it could yield the Ray Gun Mark II instead 

Summary Table

Pro Tips

• Communicate with your team—some steps, especially the keycard or power-up, are easier with cooperative play.

• Load out wisely: Pack-a-Punch weapons and perks like Jugger-Nog, Quick Revive, and Double Tap help immensely, especially during UberKlaus and at the mushroom charging stage

• If using the alternate box method, you may only get one base Gorgofex per game—others will need to get it through the Easter egg method
