Ex-Valve Writer Reveals What Might Have Been Half-Life 2: Episode 3's Story (eurogamer.net)
New submitter stikves shares a report from Eurogamer: Ex-Valve writer Marc Laidlaw, who worked on Half-Life, Half-Life 2 and its episodic expansions, has published a summary of the series' next chapter on his blog. Titled, "Epistle 3," it details Gordon Freeman's next adventure. Except, likely for copyright issues, the whole story has been genderswapped. So Laidlaw's tale speaks of Gertrude Fremont, Alex instead of Alyx, Elly instead of Eli, and so on. Naturally, Laidlaw's blog is currently down due to traffic, although you can read a backup of the page on Archive.org, or on Pastebin, where the names have been corrected.
No, it's a story with audience participation via game elements. A story which ended on a cliffhanger in act 2. People who bought act 2 basically on spec (of the forthcomingness of the final act) have cause to feel insulted by the failure to deliver on the part of the storyteller, as they have the additional investment from the participation in the previous acts.
