A scene from my story. Ah like BEEEG weapons!
Of couse, this really isnt THAT big, being infantry-based. But in case you could/couldnt tell, that weapon is a rotating-barrel energy-based infantry killer designed to pierce armor at a medium to long range with a positively DISGUSTING rate of fire. How fast, you wonder? You ever seen the US military design where they mount a vulcan cannon on an A-10 warthog or a turret-mounted version on the back of Hummers? Think of a rate of fire greater than that.
Ive got plans for this. It'l be colored eventually, for sure.
