Paradox Entertainment’s space-faring 4X strategy games Stellaris is soon going to receive a new expansion pack. Entitled “Leviathans Story Pack” it will feature massive Guardians reflecting civilizations long gone, Enclaves of fallen empires, and finally the War in Heaven, caused by two of ancient civilizations reigniting their old conflict.

Much like the Reapers of Mass Effect fame, the Guardians will hold unique technologies and be incredibly hard to defeat, quite literally serving as Leviathans for Stellaris.

The expansion pack will become available on Steam on 20 October 2016
