Try not to panic, but the terrifying facts are all too clear-- from the oceans' depths to the stars overhead, our planet is under siege from every possible direction! Relentless robots stalk the globe, seeding destruction in every step; hapless citizens transmogrify into unwilling agents of Martian militarism; humans and Venusians go brain-to-brain over priceless stolen thoughts; and the planet's climate itself is fatally compromised by a dangerous reduction in atmospheric carbon dioxide! This second volume of Showcase Presents: Strange Adventures brings to vivid life the futures that never were--and those that may yet be!

Contains material originally published in 1956-1958 in single magazine form as Strange Adventures #74-93.
