“All the resource for VR game development later in the cycle, during Alyx’s development, all of those resources got moved onto Alyx,” Coomer explained. “So at the moment, no, there aren’t three other titles in development. But, as for what’s coming, we don’t really have something new or newsworthy for you to say: ‘Once Alyx is out the door here’s what you should expect to have happen.'”

Also like, what exactly is coming next for VR? Also what’s coming next for Half-Life? We really– we’ve been working on this for four years and we’re really excited because the reception before the game is out seems to be really quite positive, so far.”
