Heavy Bowgun
From the guide book
A sniper who keeps their distance and fires many kinds of ammo
Bowguns are ranged weapons that fire ammo from a distance. Light Bowguns are mobile and reload fast as a group, while Heavy Bowguns have more firepower but less mobility and slower reloads. Learn the strengths and weaknesses of each. Apart from the variable zoom scope, a bowgun can only take one of its own removable add-on parts at a time.
Heavy Bowgun: slow with the weapon drawn, but high Attack. A mobile cannon that goes for big damage from long range. Can guard with a shield.
