Perhaps hoping to follow in the footsteps of the now-finished (and completely excellent) webcomic Concerned, The Adventures Of Hercule Cubbage is a new work of Half-Life 2 fan-fiction that tells the story of a different hero of the human resistance.
That different hero is the son of Odessa Cubbage, the man with Half-Life 2's most magnificent moustache. The framing of the comics could be a little better - you can lose track of what's happening from time to time - but that's something that'll no doubt improve with time. I've found it also helps if you read the dialogue aloud in a chirpy British accent.
There are currently two "chapters" of the comic available, which you can check out below.
