You will need to create the Wunderbuss in order to open the Pack-a-Punch.
Once you have the Wunderbuss, blow open the following electrical panels:
● In the Underbelly next to some metal bars.
● In the Destroyed Building next to the Waffe 28 wallbuy;
When the panels are exposed, shoot them using the Wunderbuss.
Once that is complete, the Pack-a-Punch machine will appear in the elevator shaft, in the Destroyed Building area.
Note: Make sure to
equip Sticky Grenades or Satchel Charges in your loadout.

*Wunderbuss Guide:
- You need to collect the wunderbattery for the Wunderbuss.
The
wunderbattery appears in one of three locations:
● In the Cabaret next to the M1928 wallbuy;
● In the Museum next to the Armor station;
● In the Museum next to the Faustblitz Machine.
- Next, you will need to input the correct frequency on the radio located in Main Street.
To know the right frequency you will need to check the code on top of the radio itself and
you must now head over to the Church.
At the church, use the code printed on the radio and the location of the map marker to get the frequency from the chart, to the left of the map.
Once you have the right frequency head back to the Main street and input it on the radio.
- Head to the Plaza area and once there find a locked box then shoot the lock and melee the flare box to launch a flare.
- Now some normal zombies will tranform into sizzler/gekocht zombies. Kill a sizzler zombie with a melee weapon to collect the
Geistbolt piece for the Wunderbuss.
- Head the basement and place the Wunderbuss battery in the door across from the Type 100 wallbuy. Once placed, go behind the generator where you placed it in and pick it back up. You are now trapped in the room. Place the wunderbattery and the Geistbolt on the weapon crafting station. Pick up the Wunderbuss and shoot the generator you placed the battery in and after it is filled up with enough energy it will re-open permanently.
