[Source] Eradicators, partially developed by the Imperial Science Bureau under the codename Special Project 62991A, were exotic satellite based weapons developed during the years of the Cold War. They were a hybrid weapon that mixed elements of biological and mechanical technology. This was because they consisted an organic battery in a metallic shell. These orbital weapons were thus able to be grown rather than manufactured so long as there was space for them to be bred. A single Eradicator if placed around a planet was able to devastate an entire city. To control them, a set of codes were needed to activate the Eradicators though if left inactive for a long period of time - they were able to randomly target locations on the world they orbited.
