Hmm, looking at the picture of the Kilrathi admiral getting toasted. The Emperor was Thrako's grandfather. The leader of the Kilrathi fleet at Goddard was Thrako's dad. Does this mean that the Emperor was executing his own son?
I think the Black Lance gun is a nod to the plasma-rifle in the game Fallout? It has the same layout.
Does Pliers call the stormfires old technology in one of the weapon-screen voice messages?
What this thread really needs now is someone to do 'tech manual' style line art of the various guns identified.
