The first two pictures of the Laser weapon set show the alien invasion beginning:

In order to fight off the alien threat, the army is developing a laser shotgun for its troops.
Where I need your help is I need an idea for what the picture is going to be. The current ones are meant to resemble something seen in a 1950's alien invasion comic book.
I can't think of what would work for the army making the laser shotgun though, so if anyone has any ideas please post them here.
Also if anyone has a more creative name than Laser Shotgun, I would greatly appreciate it. (avoid the use of the word Plasma, keep it from sounding generic, but don't make it ambiguous. IE: I don't want people complaining that they don't know what a "Larudesia" or a "LSG-14Y" are.)
[edit]
Ok so I am scrapping the original images. I will make new ones later. Any suggestions for how to do those would be helpful. Maybe post some comic book pictures for me to base them off of or such.
