It seems that Steam has added a category in their search that allows you to easily see what games are available in the platform that have support for the Oculus Rift 3D VR HMD and even though the category is called VR Support it essentially means Oculus Rift support for now. And while we may see other games supporting different VR platforms as they become available in the future, at the moment Steam has listed 14 titles in the VR Support category though the number of games is actually a bit different. You can see the list if you open the search on Steam and go to the advanced search where you have the option to select category and at the bottom of the category list you will see the new VR Support category.
We mentioned 14 titles available under the VR Support category, but the number is actually a bit different as the list includes Team Fortress 2 two times and it is also included in the Valve Complete pack where other Valve games with Oculus Rift support are only available. The game Strike Suit Zero is also available as a standalone in the list as well as in the form of a pack Strike Suit Zero Mega Bundle that includes some extra features. There is also the game Estranged: Act I that is not yet available, but should come out next month that is listed in the VR Support category.
