No One Lives Forever, had revealed in his blog that Half-Life 3 is not being developed at Valve. The statements were later removed.
Lowrie, who did work on Defense of the Ancients 2, stated that Valve was basically too busy with Steam and other titles such as DOTA2 to work on a new Half-Life game. He also discussed the fact that Valve was still sticking with the "turn and follow" method of NPC interaction with players, rather than the popular motion capture method.
The actor later removed his comments, apologizing, "(It) just seemed to cause a whole bunch of confusion and when I tried to minimize the confusion I misspoke and caused a whole bunch more confusion... Sorry that I gave the impression that I know what’s going on. I really wasn’t trying to and I really don’t know."
Half-Life 2: Episode Two was released back in 2007. Gamers are still waiting for Episode Three after the brutal cliffhanger in the second episode.
