From publisher blurb:
EARTHJUMPERS is a pamphlet micro-setting designed to be used with the Troika! RPG. In it, you play as a brave Earthjumper, humanity’s last chance at rebuilding Earth, after the devastating cataclysm that shattered it. Visit innumerable alternate versions of Earth, all of them with their own problems, in a race against time to complete your mission and return to your own earth. Will you fight the terrible Jawari, sabotage their unfathomable plans, and gather all the crystallized alternomium to heal your version of Earth? Or will you simply disappear with a loud “pop”, nobody even remembering you existed in the first place?
Within this pamphlet you'll find:
A brief setting description
A new Background for Troika!: the brave but doomed Earthjumper
A table of reasons why your Earthjumper squad would be sent to a parallel Earth
10 possible alternate Earths
The terrible Jawari. Did anyone say space llamas?
Possible mission complications
