In June 2016 Valve announced 'Destinations', a Steam workshop
not easy to find anymore, that allowed the end user to enter real and fictitious scenarios through the magic of virtual reality. The idea was intriguing, but the media was not completely sold and judged Valve's proposal as both "
the best and the worst of VR". From all this, however, came a singular discovery: those who reverse-engineered its code discovered in it the HLVR acronym, which initiated a wide debate about the potential appearance of a Half Life VR (HLVR) version specifically developed for VR headsets.
Lending further credence to this hypothesis was Gabe Newell's
announcement in February 2017 that Valve was preparing three big titles for virtual reality- two of them based on Source 2, and one of them based on Unity. More such signs appeared in the summer of 2018, and everything was pointing towards this project being indeed real, that it would likely be based on Source 2, and that it would offer a full-fledged blockbuster title that this generation of VR has been desperately seeking.
