Valve still "figuring out" Episode Three
Sounds as though Half-Life 2: Episode Three won't be rattling its way across Steam for a while yet.
"We don't know entirely what's happening in the next episode, but we're gonna figure it out," said David Speyrer, Episode Two project lead. "There are always things we want to do that we can't because of the constraints of either the story or the arc we've laid out for the gameplay - or just time."
The third and final section of the Half-Life 2 series currently has no release date.
