VRFocus - Given that the Oculus Rift virtual reality (VR) head-mounted display (HMD) is yet to see a consumer launch it’s not often that VR enthusiasts see the launch of a full videogame with dedicated support for the device. But later this month indie developer Proton Studios will launch such a title in Time Rifters, a co-op shooter on PC that takes a unique approach to multiplayer gameplay. This week the developer has given the title an official launch date and price.
