"The Grand Archive preserves and exhibits the most valuable artifacts we have collected throughout the galaxy..."
The galaxy is vast and filled with artifacts! Grand Archive adds 151 specimens to the base game, but we have revisited all of the content ever created for Stellaris to add more. The overall total is over 240 unique specimens! Collect them all and display the prize pieces in your own Grand Archive.
“…Reserved within is also a dedicated Vivarium for live Space Fauna containment and observation.”
Contained within your Grand Archive, the Vivarium is a controlled environment where wild space fauna can be cared for and studied. Space fauna in captivity will grow faster and breed more easily than in the wild. These creatures can then be dissected for research, resources, or their genetic material. With the development of the Controlled Mutations technology, Space Fauna can be customized to form a fleet which will grow and become stronger over time.
The void is full of life.
Two new forms of Space Fauna are coming in the Grand Archive Story Pack. Cutholoids are ambush predators that lurk within asteroid belts, waiting for prey.

“With the mysteries of the galaxy at our doorstep, there is everything left to learn.”
The Grand Archive Story Pack comes with two Civics, two Origins, and two new Tradition trees, each focusing on either different aspects of coexistence with Alien Fauna or the hunt for the hidden mysteries and treasures of the universe.
