In an interview with The Verge, Valve programmer David Speyrer has talked about whether Half-Life: Alyx, a feature-length VR prequel to Half-Life 2, signals a full return to the series and if fans can expect more games to follow. To this, Speyrer says: “Yes. It’s probably no surprise that many people at Valve have been wanting to get back to the Half-Life universe for a long time, and this experience has only reinforced that.”
He explains that in the process of creating the VR game the devs have had to “explore new ways to tell stories with these characters and this world, and we’ve discovered a lot of new gameplay experiences that go beyond what we’ve been able to do before.” Further to this, he adds, they’ll naturally “have to wait and see how people react to Half-Life: Alyx once it’s out, but we’d love to continue pushing forward.”
