|The following is based on the cancelled game Renegade 2 and has not been confirmed by canon sources.|
The Scavengers were a a major faction that was to appear in Renegade 2.
Born from the ashes of the fallen Soviet Union, they are a scavenger culture, living off of ore they excavate and whatever leftover Soviet tech they can find. They form the basis from which the Brotherhood of Nod emerges.
Their mission, goal or leader are not known, but naming Kane here is likely more right than wrong. However, it is known that most of their technology was Soviet based, often with makeshift repair and a junked look to it.
