A Halo mod for the critically acclaimed Sins of a Solar Empire, that aims to capture the fast paced intensity of the Halo series.
The massive Forerunner installations known as "Shield Worlds" fulfill the same general function as a human fallout shelter- but on a grand scale. With so many aspects of the civilization to account for and hold, each world encountered by the UNSC expeditionary forces has varied wildly in design and suggests specialized purposes. However, a common design element is an internal sun as a power source and housing a veritable armada of artificial intelligence forces.
Though no Forerunner has been seen in light of the revelation of the Didact's and Librarian's existence, the United Nations admiralty have been forced to conclude that the species is very much alive.
And possibly a grave new threat.
