The first installment of the Post Script episodic modification for Half-Life 2 is now available. Word is: "Post Script is an episodic narrative mod for Valve Software's Half-Life 2: Episode 2. Explore the remains of a town destroyed by its own tragedy in a collection of short, interactive vignettes. Solve environmental puzzles and uncover the mystery of how, somewhere along the line, the whole world fell out of existence completely." There's a teaser trailer from the mod on the YouTube.
