>>6018516There are a few pieces of attachment parts that plug into Gundam Astaroth's backpack. They are aesthetically similar to the tiny rod that holds the demolition knife.
There are two tiny clips that I would imagine are for the panzerfausts. Unfortunately I don't have any sturmfaust/panzerfausts, would have to wait until the kotobukiya MSG parts or find some gundam weapon packs that came with them.
These clips also can be plugged onto four holes on the side of the pile bunker. The Gunpla stock photo also used this pile bunker as a weapon storage that plugs onto the backpack rod. Giving this to Astaroth Origin gives it somewhat an Alt Eisen feel to it.
