Having trouble activating the Pack-a-Punch in Black Ops 7's Paradox Junction? Here is a step-by-step guide on how to do it fast.

While you can get the Blundergat via the Mystery Box, this guide will cover how to build the weapon as part of the Easter Egg Quest. The pieces for the Wonder Weapon can also be acquired in any order, so feel free to jumble some of the steps.

All Blundergat Part Locations in Paradox Junction

How to Get The Barrel Part

To get the Barrel, you will need to feed zombie souls to a specific Loot Cyst. Loot Cysts can be found all around the map in the future nuked version of the map and look like glowing green growths. However, to identify which cyst has the Barrel, check each one and listen out for a chiming sound.

Once you have identified the correct Cyst, feed it souls by luring enemies nearby and killing them. After enough souls have been fed to the Cyst, it will explode and drop the Blundergat Barrel.

How to Get The Hammer Part

To get the Hammer, first grab the SO3 vial item from the second floor of the yellow house in the nuked future version of Nuketown. Next, head to the green house and then to the kitchen. Interact with the kitchen sink to turn the taps on and begin a chemical reaction. Interact with the sink again to fill the vial with acid.

After this, while still in the future, run around to the different mannequins. Your goal here is to listen out for the same chime you heard from the Cyst that held the barrel. These mannequins can be found in the following locations (check the map above for more precise locations):

  • Inside and behind the green and yellow house (one is also on the deck of the green house)
  • Around the middle of the map at Cul-De-Sac
  • Dotted around Trinity Ave (Pack-a-Punch location)

Once you identify the correct mannequin, head to the past version of Nuketown, either automatically following a Special Round or by using the Temporal Conduits. Here, interact with the mannequin that made the chiming sound to apply the acid. If you make a mistake, don't worry, you can apply the acid to up to three mannequins.

Afterward, head back to the future via the Temporal Conduit and check the mannequin you have melted. If you have melted the correct one, you will find the Hammer part for the Blundergat. If they do not drop the part, it means you melted the wrong one, so interact with the sink again, and repeat the process.

Where to Find the Sealant Part

For the next step, while still in the past version of Nuketown, go to the yellow house and up to the bedroom on the second floor. On a bookshelf, you can find Sealant, which is the third part of the Blundergat.

How to Find The Stock Part

To get the Stock, first head to the future and locate one of several different black growths. These can be found growing on several different walls in the following locations:

  • In the garage of the yellow house (house on the east side)
  • At the top of the staircase of the green house (house on the west side)
  • At Trinity Ave. to the left of the VS Recon wallbuy

Listen to each wall until you hear an audio cue, which will sound like shimmering. Then, take note of which wall you heard the sound effect at. From here, head to the past version of Nuketown and go to the exact spot where you heard the sound. Use an explosive on the wall to blow a hole in it. Finally, return to the future to the same location to get The Stock.

How to Build the Blundergat on Paradox Junction

Now that you have all the parts for the Blundergat, it's time to build it. Head to the truck in the middle of the map and open it using Essence. Here, melee the Workbench to reveal the mold for the Blundergat, which you can interact with to craft. Be careful, however, as you will be locked into a crafting animation, so make sure no zombies are around you beforehand.

After following all these steps, you will be granted the Blundergat Wonder Weapon. Afterward, you can Pack-a-Punch the gun and even go ahead and begin upgrading it to the Sundergat.
