https://steamcommunity.com/games/546560/announcements/detail/1711869822747139586 Valve Index Availability and Half-Life: Alyx Preview Locations On Monday March 9th, the Valve Index VR system will be made available again for purchase after having been out of stock for some time Spoiler Recent demand for the Index system has been high, so we do expect that available stock on hand will sell out quickly. We will continue to take orders after those units have been sold, so purchases beyond this initial quantity will be fulfilled in the order in which they are received, as supplies increase over the coming months. The exact time that the Valve Index will be made available on Monday is 10:00 AM Pacific (5:00 PM UTC). If you already own a Valve Index, or have ordered one, the bonus Half-Life: Alyx preview locations have just been released and are now accessible to you via Steam VR Home. Starting now, you can download and visit two locations from the game, before the game comes out on March 23rd. One is an outdoor space taken from City 17 in the shadow of the under-construction Citadel. The other is Russell's laboratory, where he helps Alyx make plans to take on the Combine. The rendering technology available in SteamVR's native environments is different than that in Half-Life: Alyx, and the interactivity is significantly lower than what the game itself provides. So while these scenes do not have quite as much fidelity as they will in the actual game, we think they are a faithful enough translation to provide a fun VR preview of the game's setting. If you don't own a Valve Index but would like to check these environments out in VR before March 23rd, you can ask an Index owner to host a SteamVR Home session for you.
