Aliens landing in their flying saucers. Giant bugs and swamp monsters created/awoken by radiation stalk around. Robots break free from their creator's control making a giant mess of things. Fedoras (actual fedoras, not trilbys) everywhere! Yes, it's the 1950s, a time of advancement in science and industry. The atomic age. The age of really bad movies that you can now RP in thanks to This Defiant Earth, a new RPG that's up on Kickstarter.
