Vive Cosmos Elite includes a pre-installed External Tracking Faceplate, 2 SteamVR base stations, and two Vive controllers. The External Tracking Faceplate can be used with base station versions 1.0 or 2.0 as well as the original Vive or Vive Pro controllers and is easily swapped with the original inside-out tracking faceplate that ships with Vive Cosmos.
