Build any ship you can imagine out of blocks, then fly it through a galaxy that gets more dangerous toward its center. Mine, trade, fight pirates or start wars, alone or with friends. Ships break apart exactly where you shoot them, which never stops being satisfying.

Design a fleet module by module, mine asteroids in real-time physics, and watch your greed light up the sky: the more you extract, the louder your heat signature, until the aliens come looking. A slow, careful space sandbox for players who like building things that work.
