HTC is launching a Vive virtual reality headset bundle that includes a free copy of the upcoming Vive game Fallout 4 VR. Starting today, people who buy a Vive will also get a redemption code for the VR adaptation of Bethesda Softworks’ 2015 title. The game is set for release on December 12th. For people who already own a Vive and buy Fallout 4 VR separately, HTC is offering three free months of its subscription gaming service Viveport, which normally costs $6.99 a month.

HTC dropped the Vive’s price to $599 this summer, and throwing in Fallout 4 VR makes it a little more attractive. Since this is effectively a preorder, it’s worth weighing all the usual risks of buying a game before you know how well it works. Fallout games in particular tend to be somewhat buggy, especially at launch, and VR games are a new enough phenomenon that it’s hard to predict how well Fallout 4 will translate onto the Vive.

That said, this is one of the biggest games to hit any VR headset. And unlike a lot of VR games from big franchises, it’s a complete adaptation of Fallout 4, not a short spinoff. Fallout 4 VR is at least temporarily exclusive to the Vive, so it’s not a stretch to imagine this being the tipping point that convinces some people to buy one.
