Stellaris: Ancient Relics Story Pack is a new story pack for Paradox Development Studio’s iconic sci-fi grand strategy game, Stellaris. Uncover the ruins of long-dead civilizations in Relic Worlds to piece together the story of their rise and eventual downfall. Mine their derelict cities and ships to unearth the truth, discover powerful relics and harness them for your own empire’s ambitions.

Stellaris: Ancient Relics Story Pack includes:

• THOSE WHO CAME BEFORE – Encounter two new Precursors, or ancient and extinct civilizations, each with their own anomalies. Players can investigate these to understand who they were and, more importantly, what one can learn from their demise.
• RELIC WORLDS – Once teeming with life, these Relic worlds now lie dead, covered with desolate ruins and dormant mysteries. Players can create archeological sites to explore these remains and bring to light powerful relics and artifacts.
• MATTER OF ARTIFACTS – Learning from history is much more than parables and antiques, it can often be the key to understanding one’s own place in the galaxy. Utilizing archaeological research, discover Minor Artifacts, a new resource type which can help empower one’s empire.
• DIG IN – Hit the dirt on a variety of enigmatic and alien worlds with more archeology sites available for your empire to study… or plunder.

Stellaris is available on Windows PC, Mac, Linux (all via Steam and GOG), PS4, and Xbox One for $39.99.
