Humanity's vast empire is lost. With the last communication outside the Apollo Sector far beyond human memory, we've been forced to build anew, using only the dregs of the civilization left behind. Now it's your turn to make your mark and help to rebuild our understanding of where we are and where we came from.

With over 270 BILLION star systems to explore and an emphasis on strong Sci Fi, Ascent encourages Exploration, Colonization, Starbase construction, Research and technology, Asteroid mining, Farming, Trading, and - of course - Combat.
