Blitz, Weapon & Armor locations
On the first floor in front of the spawn location you can find an MP-40 which you can buy for 1000 Jolts.
Also on the first floor you can find an STG44 which is purchasable for 1500 Jolts, and the only Geistchild machine where you can buy armor which will consistently increase in price, starting at 500 Jolts and finally capping out at 10.000 Jolts
On the second floor you can find the Combat Shotgun which is purchasable for just 1000 Jolts, the Random Blitz machine which gives you a random Blitz for 2000 Jolts, you cannot reject to get the Blitz as you could with Der Wunderfizz machine in Treyarch zombies.
You can also find the Mystery Box on the second floor after unlocking it.
How to unlock the Mystery Box
Unlocking the Mystery Box in Gröesten Haus can be done within a couple of seconds.
The first and only step is to shoot a total of 10 lanterns scattered in and outside the house.
After shooting a lantern you will hear a crow and see some purple particle inside the lantern
In the video to the left, you can see the locations of all 10 lanterns
How to unlock the Pack a Punch Mystery Box
The Pack a Punch Mystery Box is exactly what it sounds like, every weapon you get from it will be Pack a Punched.
Unlocking the PaP Mystery Box is quite easy and doable within 10 rounds.
First of all, you’ll need to unlock the normal Mystery Box. After that, you will need to get a Jack in a Box (Monkeybomb) from the Mystery Box. Throw the Jack in a Box on the support beam in front of the Mystery Box room as shown in the video above.
After that you will need 10.000 Jolts, just stand in front of the Piano near the Mystery Box room and press the action key, this will subtract 10.000 Jolts and convert the normal Mystery Box into the PaP Mystery Box.
