To slay His Vampiric Majesty is to become a true Vampire Hunter-Slayer.
To slay a zombie is to become part of the last human survival group.
A Shotgun can be used for both of these tasks. In fact, a Shotgun can kill just about anything.
Well, except a Dragon, it would only make the dragon mad and more likely to kill you.
I made this shotgun to kill dragons, zombies and vampires.
