You can download Everest VR right now for $15. As with most VR titles, though, you'll need a reasonably modern Windows PC to handle the Oculus Rift experience. The developers recommend at least a 4th-generation quad Core i5 processor, 8GB of RAM and a GeForce GTX 960 to make the most of it. That won't be too much trouble if you already have a Rift, but it's something to consider if your PC is on the edge of being VR-ready.
