Where Is The Pack-A-Punch Machine?
The pack-a-punch machine is located underground, in the bunker, within the location called 'beds'.
The main aim is to turn the four lights on that are sat next to the machine itself. When all four are green, you will have activated the machine. However, this is easier said than done and will need some work.
Step 1: Turn On The Power
As is tradition in Black Ops 4 zombies, you will need to activate the power before using the pack-a-punch machine.
From the spawn point down Center Street, you need to make your way across the Cul-de-sac (Nuketown map) towards the building that sits next to the 'B' flag in Domination; this is called the 'Power House'.
Once inside there will be a lever that needs to be activated to turn on the power. You will notice the entire map become much brighter and colourful.
Step 2: Ventilation Lockdown
Next you will need to do a ventilation lockdown in the bunker, located in the 'Generators' space.
In the generators room, you will need to activate a computer terminal, this will initate the lockdown. Make sure you are stocked up before doing this as you will not be able to leave the room until it is finished.
This lockdown will last for about a minute and at the end you will be rewarded with a max ammo for your efforts.
Step 3: Repair The Ventilation Units
Next, you need to repair four ventilation units that are spread across the map; there are six locations that they can be in.
To fix the ventilation system, you simply need to hold the square button (or the corresponding action button for your platform) until the needle on the gauge goes from red to green. You should be able to shoot zombies while doing it.
The map is not massive, so it shouldn't take too long to find them. However, if you want to speed up the process you need to look for the green nova gas.
Here are all of the possible vent locations:
Operations building - The first building to the right of the spawn, in the back left room of this building attached to the wall.
APD Interrogation - The first blue building to the left of the spawn, outside the back of the building attached to the wall.
Prisoner Holding - Enter through the site entrance, go right towards the light blue building, in the left room with the cell door it is attached to the inner wall near the back door.
Transfusion Facility - Enter through the site entrance, go left towards the light brown building and out the back door, where it is attached to the wall outside.
Yellow House - The right building within the cul-de-sac, make your way through the downstairs and turn left, the vent will be facing you when you enter the garage.
Green House - The left building within the cul-de-sac, make your way through the downstairs and straight out of the back door, the vent will be attached to the wall next to the staircase.
When you've finished this step, you will hear an audio quote saying "Ventilation system operational, Nova 6 gas leak contained. Primary systems now online"
Now you will be able to go ahead and pack-a-punch your weapon including the elemntal ray guns.
