Gordon Freeman
While "Half-Life 2" follows protagonist Gordon Freeman in a dystopian future, "Concerned" follows a similar path through the eyes of "Gordon Frohman", a dangerously clumsy character who arrives in the setting of the game a few weeks before Freeman does. The webcomic's dark humor is derived from its contrasts with the game and through references to the game's shortcomings. On several occasions in the comic, Frohman becomes the cause of various disastrous circumstances that Freeman will later encounter.
