From publisher blurb:
What is Dark Matter?
Dark Matter is a full science fiction conversion for 5th Edition that unlocks a universe of adventure for your table, without leaving your favorite fantasy staples behind. The core book is is over 250 pages and will grow and improve as we add the finishing touches.
Everything in Dark Matter, from character options to space combat, is easy to learn, generic enough to use with any sci-fi setting, and made to work with 5th Edition. We take great pride in making sure that everything we write is fun and balanced for everyone who plays.
Dark Matter is for any player or GM who wants a little more sci-fi at their table. Though it's a full campaign setting, Dark Matter is designed with flexibility as a top priority: the rules and options in Dark Matter can seamlessly be applied to any 5E campaign from the definitely-not-Star-Wars settings the to all-inclusive fantasy games. You need Dark Matter if you want to throw a blaster, laser sword, or starship into your next game, even if it's only for one session.
