 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.
