“Space is a pitch black room—stick your hand out and you might never get it back. Of course, you also might touch god. It’s a gamble either way. To not try, however, is to wither and die—only those bold and foolish enough to take a chance will change their lives.”

Captain J.V. Gorham, Far Spinward Colonies, Pioneer, Weyland Corp.

All the wonder and danger of the stars is yours—if you can just wipe the grime off your face and dig the dirt out from under your fingernails first. Airless moons circle swirling gas giants, eager to be transformed into tomorrow’s paradise. Dark ancient mysteries wait to be unearthed beneath a millennium of debris. Searing solar flares boil your flesh and blacken your bones as you harness their power to light a hundred worlds. Long lost mysteries lie entombed in the frozen hearts of icy comets. Unstable tectonic plates shift to drown iridium mines in scalding lava. Even the truth of humanity’s origins awaits you out there, orbiting some dying star. And out there amongst it all is something truly horrifying—something that nature never intended.

Something alien.
