Heroic Land-Dwellers!
A collection of playable human characters for a roleplaying game of science fiction, drama, and farce. The characters defend Earth from aquatic monsters that seek to invade, destroy, or enslave humanity using lasers, hypnotic gas, and other strange threats. Sixteen characters include biographies, statistics, Quips, and artwork, allowing them to serve as protagonists, supporting characters, or villains. Fiction by Larry Blamire establishes the action-packed, nonsensical tone of classic science-fiction B-movies.
