Ceres

"Ceres" is a single-player Science Fiction Role Playing game with a good plot set in a ravaged solar system where Earth has been destroyed. The solar system has been changed due to the malfunctioning of the Gate, a device built to connect Earth to other stars. Now, human factions are at war, monstrous machines and alien creatures roam, and real dangers and myths intertwine in this cold, dangerous world. However, be aware that the game is very buggy.
