The community has found a new reference to Episode Three & Alyx Vance in the comments of a Python script for the Source Filmmaker. Also, there's a line of code that refers to a Source Engine 2. Here are the code snippets: Line 49: _CONTENT = Nonedef content():'''returns a Path instance representing the %VCONTENT% path - path construction this way is super easy:somePropPath = content() / 'ep3/models/characters/alyx/maya/alyx_model.ma''''... Line 76: _TOOLS = Nonedef tools( engine='Source 2' ):... Here's the Pastebin of the entire file for your convenience. If you have SFM, you can find the source for yourself at: ".../SourceFilmmaker/game/sdktools/python/global/lib/site-packages/filesystem/valve.py" What's the point of reporting this? Well, it seems obvious that, after 5 years of complete silence or "hang in there's", Valve's getting comfortable talking about Half-Life again. It all started when a Valve employee was found wearing a Half-Life 3 shirt at a local game developer meetup. In my personal opinion, the leak was intentional and meant for the fans, but I'm loco like that. Since then, some of Valve's head figures have begun to be more open about the subject in recent interviews. For example, Gabe Newell went on the 7DCD Podcast and openly discussed how 'Richochet 2' has a giant story arch, and it has been in development for years. Also, Jeep Barnett, with GamesTM, talked a little bit about how the Half-Life universe is so deep that "there's a lot of elements that tie together in unusual ways." And more directly, Valve has planted hints in a Dota 2 blog post. A picture of a lambda, and the HTML alt tag for the image reads "Lambda Lambda Lambda". Is this proof that Valve is finalizing the design for Episode Three? What do you think? Thanks to walropodes from Facepunch for finding the new Ep3 reference!
