Play Half-Life 2 in virtual reality with your Razer OSVR headset thanks to Steam

Here’s an excuse to play Half-Life 2 again.

Gaming hardware and peripheral maker Razer announced today that several SteamVR games, including popular hits like Half-Life 2 and Team Fortress 2, are now available to play in virtual reality via OSVR, an open VR software and hardware platform. Users can play OSVR games with the Hacker Development Kit, a headset that costs $300 (which is cheaper than the preorder price for the $600 Oculus Rift and the $800 price of the HTC Vive, which is backed by Valve). Tech adviser Digi-Capital predicts that the virtual and augmented reality markets could grow to $120 billion in revenue by 2020, and having classic games like these available in VR can attract skeptical consumers.
