Space is lovely, dark and deep, but it has secrets it wants to keep. Rich systems defended by fierce creatures, hostile pockets of resistance to your civilization, and the sleeping giants of the universe – the Fallen Empires who may yet be stirred from their centuries long indolence. In Stellaris: Leviathans, the galaxy will be filled anew with adventure and challenge as your new and naïve space-faring empire comes face-to-face and ship-to-ship with a host of dangers and rewards. https://www.youtube.com/watch?v=REijXUSQrQc

• Guardians: Stationary societies that have built defenses throughout a system to protect something of great value. Do you dare seize their treasure?
• Enclaves: Independent outposts of traders or mercenaries who are willing to make a deal. Exchange resources or hire a small fleet to supplement your own.
• War In Heaven: Where will your fledgling empire lie if two ancient Fallen Empires decide to renew old grievances in a War in Heaven? Will you err on the side of caution and take a side with the stronger power, or will you strike at both whilst they are occupied with their own titanic struggle?
