The Scorched Earth is a intel document in Resistance: Retribution.
Transcript[]
From what I can tell, the German government collapsed long before the Chimera arrived -- probably under the humanitarian burden caused by countless refugees from the great Exodus. Military papers are scattered everywhere. Orders given to evacuate the cities. Refugee camps being built all along the Rhine. More troubling than anything is a series of "scorched earth" orders given from Luxembourg: they ordered everything destroyed from Bonn to Luxembourg, as if they thought that would stop the Chimera. I guess I can't blame them. During those early, dark days, no one knew what the Chimera were, or how to stop them.
