After Dark
Jude Stroud ($4.41, 23 page PDF)

After Dark is a new reality show, looking to cash in on the popularity of 'real' hauntings. You're hoping to cash in too, as contestants in the very first episode. Details are sketchy; you know you're being taken to spend two nights in a haunted location somewhere in Maine, there will be some sort of challenges to complete there, and there will be no production crew - the show is to be filmed entirely on body-mounted cameras.The waiver you signed made one more thing clear; there will be no phones, no internet, and in an emergency, help may take hours to reach you. If something goes wrong, you're on your own. Good thing ghosts aren't real... right?

The Crimson King: This scenario takes place in the early 1980s. The characters have been invited to an exclusive nightclub that features early goth music with industrial and punk influences. Illicit drugs and overt sexuality are ubiquitous with the underground nightclubs of the time, and by all accounts The Court of the Crimson King is no exception.

A group of friends have rented a small vacation house with the intent of spending a week fishing, drinking, and maybe smoking a little weed.

Unfortunately, everything takes a downward turn on the fourth day when the kids begin complaining of nausea and cramps. The counselors decide to give the kids something to settle their stomachs and send them to bed early, convinced that everything will be better in the morning. They couldn’t be more wrong.

Jackknife: This scenario takes place in the 1970s on some highway in the Southwestern United States. Making the long haul across the New Mexico desert with a load of lumber, Jackknife Samson decides to pick up some desperate-looking hitchhikers, but he gets more trouble than he bargained for when they find themselves being hunted by a cult of psychotic snake worshipers for hell. [

Note: Jackknife is a light sequel to Highway of Blood, and may contain spoilers. So if Keepers intend to run Highway of Blood for their players, they may want to hold off on this scenario, or fold it into the story at the end.]

Friday Night Double Feature!

Hell Block Five: Irongate Penitentiary in Aylesbury, Massachusetts houses some of the most infamous criminals in the United States, and Cell Block Five contains the worst of the worst.

First Night: In the Fall of 1980, a group of college girls decide to spend the night in the mansion that was recently purchased by their sorority. Unfortunately, their slumber party turns into a nightmarish fight for survival when they use a witch board and accidentally summon a terrifying entity from another dimension. Unless they can figure out how to send it back, none of them may live to see the dawn.

Note that since this involves the members of a college sorority, all of the player characters are female.
