HTC today announced that a VR experience based on HBO’s hit TV series Game of Thrones is set to launch exclusively on Viveport Infinity starting tomorrow, supporting Vive and Rift.

The experience, called Beyond the Wall, is said to transport users to the northern border of The Seven Kingdoms to fight and defend ‘The Wall’, the megalithic structure separating the South from the untamed North—a place that plays host to the mysterious rise of an army of undead wights under the behest of the ‘White Walkers’. There, players will be able to test their sword-fighting skills against an undead polar bear and hoard of wights.

Beyond the Wall made its initial debut at select AT&T stores as a ‘4D’ brand engagement activation to promote the season finale of Game of Thrones; this represents the first time users will be able to jump into the experience at home.

Beyond the Wall was created by HBO and Framestore, the Oscar-winning studio known for their work not only in film and TV, but also immersive experiences such as the Game of Throne-themed VR activation Ascend the Wall, and the recent Magic Leap GOT experience The Dead Must Die.

Since Beyond the Wall is exclusive to Viveport Infinity, HTC’s Netflix-style game subscription service, you’ll of course need to be a member to play.

Viveport Infinity is typically available for free for a two-week trial, costing $13 per month afterwards (or $100 annually), which gives you unlimited access to a 500+ VR games and apps. Take note: throughout the month of June, both new and existing Infinity members who own an Oculus Rift or Valve Index will be able to redeem two free months of the service.

There’s just one more catch. Beyond the Wall is launching first in English in the US, Brazil, Mexico, Argentina, the UK, and Canada. You can probably thank the patchwork of licensing issues that official IP releases necessarily face when they head across borders.
