From the introduction:
Hello, wonderful Game Master.
Now, about the short game you’re going to run. It’s called Crossing Borders and it is a remake of the Fastaval scenario Naboerne by Johannes Daa. The setup is simple. Eight players play the roles of four couples who are neighbors in a small community, and who - during the course of the game - will go from despising their neighbors to murdering them in the best splatter tradition.
It’s a comedy, and is meant to be fast and lighthearted, so don’t worry about stuff like deep immersion, bleed, and 360 illusion. This is supposed to be fun and give your players a shared (and hopefully entertaining) experience.
