There's a pen and paper RPG that I play called Arcanis that has introduced firearms to the usual sword and sorcery mix. It's just basic flintlock rifles and pistols but they truly are a fire and forget weapon dealing a large amount of damage then they are a club and treated as an unbalanced weapon. The game designers were going for each PC to carry several flintlocks fire, drop it then fire the next and so on till there is no more pre-loaded weapons. I could see something like this working for Project Eternity.
