From September, Viveport will be supported on Oculus Rift, doubling the potential audience for all Viveport-published titles.
President of Viveport, Rikard Steiber said ‘“By adding support for Oculus Rift, we’re doubling the potential user base for Viveport developers. Viveport continues to offer the most opportunities for developers to monetize their VR content. From Viveport and Viveport Subscription, to availability on Amazon and in Viveport Arcade, we’re going to continue to expand and reach the largest global audience possible on developers’ behalf.”
