In March 2019, Valve surprised the VR industry with the tease of ‘Index’, its first self-made VR headset. Index would go on to launch later in May 2019 and be seen as the enthusiasts’ choice in PC VR headsets for many years to come. Unbeknownst to the world, by the time Index was released, the company had already been working on aspects of what would become its second VR headset, Steam Frame.
