Koop Stellaris: Grand Archive - DLC - SteamStellaris: Grand Archive - DLC - Steam

What does it take to contain a galaxy?

In the Grand Archive Story Pack, uncover and showcase the rarest treasures across the cosmos—both living and inanimate. Amass an unparalleled collection of xeno-geological artifacts, relics of forgotten civilizations, and untamed space fauna in your Grand Archive, a groundbreaking new megastructure.

Will you become the galaxy’s greatest curator or sell your finds for untold riches?

Harness advanced gravity snare technology to safely capture and study space fauna. Clone these creatures to create fleets of formidable fauna customized through genetic mutations. But tread carefully—two new deadly species, the asteroid-dwelling Cutholoids, and the sinister Voidworms, now roam the galaxy.

Explore, collect, and showcase. The galaxy is now your personal treasure trove.
