Beat Saber is available for the Meta Quest 1, 2, 3, and Pro, the PS VR and PS VR2, and PC headsets via Steam.
People who own Beat Saber on the Meta Quest 1 will be able to still play it.
So the copy of Beat Saber and its DLC a Meta Quest 1 player owns will also work on the Meta Quest 2, 3, Pro, or Rift devices.
Beat Games and Oculus VR announced that Beat Saber will not be supported on the Meta Quest 1 starting on November 2, 2024, with no new updates, customer support, and other elements being cut or phased out at that point.
