They Came From Outer Space!
This tabletop roleplaying game supplement shifts the action from underwater threats to an era of flying saucers, alien invasions, and science-fiction adventure. It adds archetypes, tropes, and other setting details for creating Astronauts, Survivors, Eccentrics, and Mouths, while remaining compatible with the rules and style of the related game. Characters can join forces against extraterrestrial dangers as they confront the end of the world.
