A really really big gun
designed to put down and stop raging mobs
of people rather quickly. Generally used by policemen
behind Lexan shields
with bulletproof vest
Riot guns generally try to get across the following impression:
Hello. I am a riot gun. I have a long, long serial number and unit name involving references to long dead cats and powerful sounding 'B movie' monsters. An example of this is "Unit XR31337-A5-QDIE-WHISKASREVENGE-LOKORTHEDEATHMONSTER-561290532324-Z". I am here on the sole mission of taking you and destroying you as quickly as possible. I apologize for any bodily harm or inconvenience in your schedule this might cause. NOW MOVE OUT OF THE WAY! Have a nice day. Please pull up to the first window.
Also, riot guns are noted for their ability to shoot almost anything shootable.
