The Red Scare is in full effect. The words “atomic” and “bomb” are on everyone’s lips. This could be the 1950s we all know, except everything is cranked up: the paranoia, the pop culture, the fear of global destruction. Everyone is a little more protective over their homeland, fearful of the neighbors, and when word spreads of the Soviets consorting with aquatic monsters, it doesn’t take long for the rumors to gain traction.

They Came from Beneath the Sea! is a tabletop roleplaying game in which the players, as humans, live in a world under increasing attack. The attackers? Aliens from beneath the sea, obviously!

Adventures can range from the one-shot defense of small coastal town, to the lengthier liberation of a cruise ship invested with gill-kin, all the way to a campaign in which characters seize an alien submarine and ride it all the way down to the sea bed to take the fight to the invaders.

In this game, the protagonists are strong-jawed war veterans, cunning and resourceful explorers, utterly insane scientists, and blue-collar heroes, just looking to defend their patches of land. Each appears as in the B-movie classics of the era, providing a wealth of inspiration for the kinds of characters you’ll play in this game.
