As the game’s time period was 1930s or so I came up with the idea of a Vampire Hunter Super Weapon ... which was to reload shotgun shells with a short stack of dimes (1930s dimes were silver
Turned out to be a very effective weapon (in the game anyway) for blasting any number of monster types as silver kills vampires, werewolves and shotgun slugs (silver or otherwise) kill pretty much everything
But don’t try this at home. Happy Halloween
