Currently only nine lonely games can be found searching for VR support on Steam but for a service that started out with just one game and its mod, Half-Life, the possibilities seem endless. Some of the games you can enjoy with VR support right now are the Valve Complete Pack that includes Half-Life 2 and Portal 2 among many, many others. The comically frustrating Surgeon Simulator 2013 and Strike Suit Zero among others.
Valve, the creators of Steam has been working on its own virtual reality hardware just like Oculus VR's Rift headset. In November Valve revealed that it will demo its first set of hardware in early 2014 as well as to unveil plans to integrate virtual reality games and media into Steam.
Unfortunately the common gamer won't be able to enjoy the immersion of the Oculus Rift until it launches next year. Oculus VR says that the headset will launch later in 2014 for PCs with possible Android support to follow at around $300.
