From 2006 to 2007, Arkane Studios was hard at work developing an official third-party Half-Life expansion for Valve. Set in Half-Life 2’s Ravenholm, the player followed Adrian Shephard (Opposing Force) and Father Grigori (Half-Life 2) as they travelled across the iconic zombie-infested town battling new and old threats alike.
 
Unfortunately, despite Arkane’s enthusiasm for the project, it was cancelled by Valve in 2007 for unknown reasons. Since then, a build of the game has simply sat dormant at the company for over a decade, unfinished, but very playable.
 
On May 26th, 2020, the crowdfunded video game documentary channel Noclip was able to produce a long-form documentary on Arkane, including over 15 minutes of exclusive access to this Ravenholm title, showcasing various levels, scripted sequences, and new gameplay elements. Outside of the documentary, Danny O'Dwyer, who was responsible for the documentary, has described his full experience with the build, and indicated that a wide array of content is quite playable.
 
As of August 7th, Arkane employee Sébastien Mitton’s (imperfectly) translated statement on the matter is this:
 
“Now we are part of Bethesda, this was our project before we signed with Bethestda. Everyone wants it to be released, a demo to be made, that we give that to the community. I see that everyday. For now we don't know. If the demand is so high, something may happen, but yeah, we made it, I brought us a lot of things, of course we want something to happen, but it's on the old source engine, so a lot of things have to happen.”
 
This petition is meant to communicate to Valve, Bethesda, and any other parties who are potentially holding the release back that the demand, indeed, is very high. Half-Life fans, modders, and archivists alike would be delighted to have a build of the game to play, study, and perhaps breathe new life into. Even a cut-down or scrubbed edition of the game as it stands right now would be better than nothing!
