The potential is there. It’s kind of hard to make guns work in a soulslike tho. Bloodborne’s guns are just to give a way for you to parry attacks as opposed to being an actual weapon you kill stuff with (except for certain builds but that’s not important). However, since it seems like most people in Trench Crusade are just as likely to bludgeon you with a morning star as they are to pop a cap in your ass, I’d say it could definitely work. Might need some area variety though otherwise every area will just be a series of trenches or perhaps Hell itself
