 In Half @-@ Life 2 , the player takes on the role of Dr. Gordon Freeman . Throughout the game , the player follows the story of a dark , dystopian future in which mankind has been enslaved by the Combine , a mysterious alien enemy . In contrast , Concerned follows the same general path through the story established by Half @-@ Life 2 , but instead follows the adventures of Gordon Frohman , a hapless , lethally clumsy oaf who arrives in City 17 a few weeks before Freeman . Frohman is incredibly naïve and , unlike the other citizens , seems to enjoy living under the rule of the totalitarian administrator , Dr. Breen , and the Combine . He holds an insane reverence for the latter , even going to the point of having a plush doll of a Combine soldier .
