Obviously this would have to be balanced out with the long awaited snowball launcher. :p
and a watercannon :)
Maybe at last a chance for implementing racial effects on racial weapons?
Burning Brazer becomes a flamethrower, electric bowgun a stungun, and create a waving autolauncher to be a watercannon :)
Not quite sure what a living rifle would do, spit venom maybe?
