From publisher blurb:
Beyond the black holes lies the Slipstream, a pocket universe of shattered worlds, desperate aliens, and savage monsters. Ruling over the shattered isles is the diabolical Queen Anathraxa, who some say is close to finding a way to escape this interstellar prison.
Strap on your rocket pack, charge your ray gun, and prepare to blast off into the the most wild and exotic Savage Setting yet — the Slipstream!
Slipstream is a pulp science fiction Plot Point™ setting for the award-winning Savage Worlds Roleplaying Game™ in the style of Flash Gordon, Buck Rogers, and the rocketeering heroes of space opera.
