But that's just it: the supposed gun is designed in such a way as to have no functionality. Unless it's actually a hair dryer. But at least being alien would explain why the design is pretty odd for a hair dryer.It looks like its does because of the gun designer and manufacturer ingame having a interest in old 'Banu' ( alien, well not human ) weapon design that has a more artistic flair on top of mere functionality.
e: Also, I'm not sure the Banu even have hair.
