The virtual reality app subscription service Viveport Infinity is now available for Valve’s Index VR headset, HTC announced, bringing all-you-can-watch and -play content to the most deluxe consumer VR platform yet available. Starting today and running through September, Index users will receive two months of free service, regardless of whether they’re already Viveport Infinity members.

For $12 per month — $9 monthly if prepaid annually — Viveport Infinity users get access to hundreds of VR apps and games that can be used across multiple PC VR headsets, including HTC’s own Vive, Oculus Rift, and Windows Mixed Reality headsets. The company says it’s now offering “much more top-rated VR games and apps” to users, thanks to greater developer engagement.

While some have called Viveport Infinity the Netflix of VR, HTC is marketing the service as an opportunity for new VR users to “discover their favorite VR games, apps and videos,” potentially making purchases of content sampled in the library. Infinity adds new apps and games each month to keep its catalog interesting, while also offering Viveport Video content, frequent coupons, and free app giveaways to members.

Valve Index users can take advantage of the free two-month promo deal through this link by downloading the Viveport desktop app and plugging the Index into the PC for verification. New users will begin a two-month trial of Viveport Infinity, while existing users will get two months of free service added to their accounts.
