He gives Divayth Fyr some company
But more on topic, I know the dwemer were able to make their robots fire guns. You have to fight them in the Tribunal expansion, and their ammo is classified as darts. Not to mention those robots hurt a lot
I haven't played Tribunal for a while, so I'm not sure if they use a built-in crossbow device or explosives to propel the darts.
Of course, the Dwemer also had Satchel Packs, and they seemed to fit the bill of something like gunpowder but weaker than dynamite.
