From publisher blurb:
Space is dark. Space is cold. Space is deadly. This isn't a universe of clean cut heroes saving the day or plucky rebels fighting an evil empire. This is a universe of corrupt mega-corporations, uncaring governments, and living for the moment because it could be your last. This is Stark Space.
Stark Space is a humancentric, dystopian supplement. It has an implied setting of a rough and corrupt universe. Stark Space contains three new classes designed for gritty space adventure: The Brains, The Face, and The Muscle. It also contains three new "races".
Max-Gene's: Humans who have been genetically altered to be superior physical specimens at the cost of their minds.
Simulants: Bio-mechanical androids who are so close to being human that there's doubt that aren't.
Psi's: Humans who developed extraordinary mental powers.
Also included are optional combat rules, equipment, and antagonists.
