Warsat
Warsats are military satellites that were built during the Golden Age. Thousands were launched into orbits above planets across the Solar System. Together with hardened surface installations, the Warsats formed a vast communications and defense network throughout which the Warminds distributed themselves. During the Collapse, as humanity's defeat became certain, Rasputin ordered the surviving Warminds to isolate themselves and enter long-term dormancy, leaving the Warsats empty and idle for centuries. When the Cosmodrome array on Earth was reactivated by the Guardians, Rasputin regained access to the Warsat network and its weapon systems.
Derelict Warsats periodically fall from orbit on Earth, the Moon, and Mars. The location where one impacts becomes the site of a Public Event. Guardians must defend the Warsat from enemies while it is scanned and transmatted by a Ghost to the City, where it can be carefully studied by the Cryptarchs.
Engineers of the City have been reverse-engineering Warsat technology, such as the self defense mechanisms used in the exotic Titan gauntlets ACD/0 Feedback Fence.
