Mass Effect Krogan Profile, Part Two

IGN continues their coverage of the Krogan in Mass Effect, once again with BioWare's Drew Karpyshyn providing us with some of the dying race's tragic history.
Roughly 2000 years ago the Krogan were a primitive tribal species trapped on a world suffering through a nuclear winter of their own making. They were liberated from this state by the Salarians, who "culturally uplifted" the Krogan by giving them advanced technology and relocating them to a planet not cursed with lethal levels of radiation, toxins or deadly predators.
