內容簡介 What if... Mars invaded Earth in 1987, and then again in 1938? Venus is a lush jungle planet abundant with life, and where dinosaurs still roam? Nuclear rockets ply the space lanes between Earth, Mars, Venus and the asteroids? Psionics and other powers are a reality? The year is 1959? Worlds United is a Mythras campaign setting where the Golden Age of Science Fiction really happened. Gernsback-era gleaming alloy air cars cruise the highways of America, and humans mingle with winged Martians, Venusian lizard men, and the strange Ophidians who are masters of chemistry. Yet, while the vampiric octopoids of the first two Martian invasions have not been seen in a generation, somewhere below Olympus Mons, steadily, they are drawing their plans against us. In Worlds United, your characters are adventurers with extraordinary powers. This is a game for John Carters, Doc Savages, Lensmen of all hues, and the strange, exotic, planetary adventure stories of Clarke Ashton Smith and Jack Vance.
