Sins of a Solar Empire

Artifacts are technology improvements that cannot be researched. They are found randomly on planets via the "Explore Planet" planetary improvement.

  • Unlike discovered planetary resources such as "Skilled Miners" which only affect objects within the current gravity well, the player that owns the planet that an artifact is resident on receives the benefit automatically for every vessel or unit in their entire empire. If another player conquers that planet, the original player who found the artifact loses the benefit; however, the conquering player only gains the benefit when they invest in Explore Planet themselves, despite "knowing" the artifact is present.
  • When an artifact is discovered, every player in the game gets an alert (same as when a super-weapon is built/fired) and the planet is specially marked on the Galaxy Map. All players can see which explored planets have discovered artifacts on them, but the exact type of artifact is unknown to all but the player who currently controls it.
  • The Advent can explore planets more efficiently with Divination in the Harmony Tree.
