A double feature is no more than a couple of movies exhibited in sequence for the price of one, but the term remains connected to the exploitation movie phenomenon of the 1970s, which took place mainly in the old “grindhouse” theatres. In this case, the name double feature is used because there are two one-shots included. Also because the adventures are primarily meant for the Wretchploitation game. They are both horror adventures easily used without any preparation if you mean to run them in Wretchploitation or any other contemporary horror game. With some adaptation, you can run them in Wretched Époque or other games set in past.
The first scenario, The Old House, is a loose collection of ideas and random tables for supernatural encounters in a haunted place. The second adventure, A Sweet Serenade, is a more structured scenario about a group of characters (that may be vampires, humans or half-breeds, depending on the Game Master’s and players’ preferences) who find themselves waking at dawn, in a strange place, after a night of partying. They may have broken the annual truce among vampire clans by murdering a woman and now must find out what really happened the night before. Both of these small scenarios can be used as one-shots or included in a horror campaign without spending much time preparing.
