Has this subject been discussed yet?
The thought occurred that Farmer Joe might have a bolt action 22 calibre rifle, so rather than fleeing he might be (albeit harmlessly) pinging shots off at the aliens...
Or the aliens crashland in an urban gangland ghetto, and find themselves faced with a small group of civilian gangsters armed to the teeth with small arms, pistols, rifles, etc.
What are the chances of this happening in-game?
