I don't think anyone has made a flamethrower in this game before I just started this a few hours ago as a proof of concept, no model yet, just Jbeam that shoots up to 10 (not enough yet) fire nodes while you hold a key. Unfortunately the heat can't transfer between vehicles so it's purely visual. But I could modify the strength at which the nodes are shot and disable the fire, and that would be a machine gun, pretty cool. Still, I want to be the first to make a flamethrower, and guns have been made before, so I'll stick to this.
