They Came From Beneath the Sea!

A tabletop roleplaying game inspired by 1950s science-fiction films, in which human heroes defend coastal communities and other locations from aliens rising from beneath the sea. Characters include war veterans, explorers, scientists, and blue-collar survivors. Scenarios range from one-shot defenses and missions aboard infested cruise ships to campaigns that take the fight into alien submarines and down to the seabed. Multiple alien factions, including enslavers, invaders, destroyers, primordials, and spies, create varied threats and conflicting objectives.
