Concerned
From Combine OverWiki, the English Half-Life Wikia
Concerned is a webcomic set in the Half-Life 2 universe, written by author Christopher C. Livingston. It follows a hapless and clumsy character named Gordon Frohman on his travels through the areas featured in the game, and begins a few weeks before the start of Half-Life 2's storyline. The title comes from one of the first Breencasts seen in Half-Life 2, wherein Dr. Breen references a letter from a "concerned citizen," which the comic takes to be Frohman himself.
