HTC own Virtual Reality headset is under development in co-production by both HTC and Valve Corporation which have now revealed a Portal tech demo using the HTC Vive VR headset. The demo is showcased using the Source Engine 2.
Half-Life and Portal writer Erik Wolpaw has detailed how his team has been using Generative AI for research and development at Valve.

Valve has responded to New York Attorney General Letitia James' lawsuit against the firm, stating it does not believe that lootboxes in its Counter-Strike 2, Dota 2, and Team Fortress 2 games unlawfully encourage minors to gamble, adding it was "disappointed" to see the action go ahead despite efforts to "educate" the NYAG about virtual items since "early 2023."
