From publisher blurb:
This version of Cthulhu Eternal is specially designed to support Lovecraftian games set in star-faring future eras, anywhere in the known (or unknown) cosmos. It particularly aims to support gritty types of horror/sci-fi crossovers which hint at terrifying alien vistas, baffling mysteries of unexplained lost races, and dark and corrupt human motives to bend the universe to humanity's profit. If you have ever had the urge to run a claustrophobic bug hunt on an infested deep space trawler -- and give it the tagline "In Space, No One Can Hear You Say Iä!" -- then this game is for you.
The Cthulhu Eternal Future SRD aims to support a broad spectrum of different types of Lovecraftian game set in humanity's horror-filled future. Heavy on mystery, isolation, paranoia, conspiracy, fear of the unknown, helplessness, and subversion ... themes which run deeply through the earliest tales of Cosmic horror. These rules take the traditions of classic Lovecraftian horror and propel them into the inky vastness of infinity. Do you dare to find out what is lurking on the dark side?
