Infinite Space III: Sea of Stars

Infinite Space III: Sea of Stars re-defines the space-roguelike genre started by its ancestor, Strange Adventures in Infinite Space, by expanding the randomly-generated region of space into the third dimension and introducing a living world where alien empires follow their own agendas that sometimes coincide with the player's, and sometimes oppose it. But at its core it is still the short-form, infinitely replayable "instant space opera" that the previous Infinite Space games made popular. Your mission is to explore the sector of space and collect artifacts, lifeforms and other valuables while putting together a flotilla of ships to fight increasingly dangerous alien adversaries.

Sea of Stars is currently available on Steam Early Access. While the basic game is fully functional, more content and some bells and whistles, such as mod support, are still in development.
