I have another weapon idea, a heavy shotgun like the one used in that one really slow ass tank (I think it was called the t95 "something" turtle), since the scatter gun is kind of lacking in power
the flamethrower should have a slight spread since fire expands in the air... which gave me the idea of a jet flamethrower that has limited range but melts through basically everything and the closer you are the more damage it deals
The flamethrower weapon will have some improvements in the next update. I don't think a second one will be necessary, it sounds too close to the laser.
