From publisher blurb:
Just what IS Betelgeuse? Well, it is a sum of its parts. Part sci-fi, part fantasy, part western, part world war, part post apocalypse, part survival horror, part comedy, part vengeance, and part habanero juice rubbed in your eye. There you have it! Hope you enjoy, because there’s plenty of things for everyone.
This 202 page extravaganza is a Campaign Setting made for the Pits & Perils rpg, and even has enough narrative and fluff to make it great for a read or you could just as easily convert it as you see fit.
