Shades of Grey is the fourth mission in the main campaign of the game.
"Revenge is a dish best served cold, Underlord, but we’re a bit… lacking in refrigeration. The traitorous coward Marcus has made a deal with the Empire to save his own revolting hide; he defends the final Inhibitor, and, in exchange, the Empire’s dogs leave him to cower behind his dungeon’s walls. Get in there, Underlord, and tear it all down!"
Defeat Underlord Marcus and destroy the final Inhibitor he foolishly guards.
"A job well done, Underlord. Marcus’ shattered spirit will not soon forget the price of his cowardice! Now that the Inhibitors all lay broken, only one final snag prevents us burning the heart of their land."
