I've never actually played Half-Life, but I've read articles about it, and I have seen no evidence that there are any female characters in the game. Having female characters is usually Requirement #1 for a lemon 'fic; I've also noticed that there seems to be a weird synchronicity between how strong a character the woman is and how depraved the lemon is. For example, Lara Croft? International adventurer, definite personality, well-defined character traits? Nothin' but rapefics.
Lemon writers do not tend to be the most... stable of people. Present company deliberately included.
