Junction Point worked on some "Half-Life stuff" at some point
In the book "Gamers at Work: Stories Behind the Games People Play" which was released in 2012, Junction Point's Warren Spector states that at one point before Disney bought the firm, it was "working on some Half-Life stuff.
Spector has said before that he worked with Valve on something, but he never said that it was Half-Life-related.
The studio was formed in 2005, and according to Superannuation by 2007 the studio was no longer working with Valve on anything - probably because of the Disney purchase in July 2007.
Considering Half-Life 2 was released in 2004 for PC, looking at the various format release dates, it's possible Junction Point worked on the console versions in some capacity, as the Xbox version was released in 2005 and the Xbox 360 and PS3 versions hit during 2007. But you never know.
Going back to Super's sleuthing, a resume belonging to an early Junction Point artist states he worked on "Half Life 2 doing texture creation on levels and character in Photoshop and Maya."
Lot of Half-Life related stuff has been in the news lately. But, so, yeah. The more you know etc.
