Civilians

Civilians are the human beings on 1947 planet Earth. They have very primitive technology compared to the aliens and their Mothership. They use, ugh, inorganic mechanical technology. Eww.

They are also easy to shock and confuse since except for a very small handful, they have not seen such advanced technology as the aliens' before. Just seening a saucer renders them dumbfounded for a time. As such they are fairly easy to adbuct using the saucer's ray.

However, what they lack in tech, they make up for in numbers and aggression. After a time, they will snap out of their shock and run for help from their authorities. As Civilians report saucer sightings, its threat level increases until the human Military is triggered into action.

Uses

Human beings are the best source of genetic material used by the Mothership to create specialty alien clones.
They may also provide some biological material (aka - meat) used for energy and other cloning purposes. However, human beings are considered a lesser source for that when compared to other animals that can be collected from the planet Earth.

Regular Civilians

Stop and stare in confusion for a time before running away.
If they are able to make it to a report station, the Saucer's threat level will increase and a higher percentage will go into the Paranoid NPC state.

Horny Young Adult Civilians

often found in vehicles or secluded areas to practice their premature mating rituals. They will have a much smaller field of view than other regular civilians, focused pretty heavily on themselves, and so are easy to sneak up close to for abduction.

Cultist Civilians

often grouped together in their own wilderness compounds. They will not run from a saucer, assuming it is there to fulfill one of their prophecies.
They also will not become Paranoid. If they are not captured initially, they will simply await their turn, eager to be taken up.

Paranoid Civilians

These folks will start running much sooner and faster than regular NPCs.
If they are able to make it to a report station, the Saucer's threat level increases at a lower incremental rate, but they'll make up for it if reporting in greater numbers.

Civlians with cameras.

It's the 1950's so not every person has a phone with a built-in camera on them but there is a definite percentage.
They will take the same amount of time to snap out of their confusion, and then take their time to snap a picture.
If they are able to make it to a report station, they will increase your threat level in much greater increments than Regular NPCs.
