If you've already got a HTC Vive, you might be in two minds about forking out for the complete Cosmos Elite bundle. If you've got base stations and controllers already, why drop dollars on more? But HTC has you covered. In the coming weeks, it will be launching a headset-only version of the Cosmos Elite and the external tracking faceplate as standalone products. And as is the case for the complete Cosmos Elite package, both purchases will come with a redemption code for Half-Life: Alyx.
