From publisher blurb:
Shadow of the Eclipse is an occult-themed, yet light-hearted superhero adventure, inspired by the classic gothic, occult and horror themed heroes and villains from comic books. As a mysterious celestial event plunges the world into darkness, the PCs must follow a series of cryptic clues that lead them deep into the desert, where they must face an ancient evil and prevent it from escaping its prison and plunging the world into darkness.
Not only is Shadow of the Eclips an exciting new adventure that shows off how S.M.A.S.H. can be used to capture the feel of occult-themed comic book stories, but also includes a handful of brand new power moves, upgrades and special rules to expand out the hero archetypes, AND some pregenerated characters so that the game can be readily used for one shots and as an introduction to S.M.A.S.H..
Shadow of the Eclips is a fantastic new setting-agnostic adventure for S.M.A.S.H., but could be used as a generic adventure for any superhero RPG with a little work.
