Since I started writing about virtual reality, Half-Life 2 has been at the very top of my list of games I wanted to experience in VR. Half-Life 2 Virtual Reality with the Oculus Rift and Razer Hydra Clear HL2VR instructions on how to use the mod show the proper way to calibrate - once you learn how to do it, you’re golden. Oculus Rift rendering for Half-Life 2 now uses Valve’s built-in implementation (the -vr launch option), and the Razer Hydra works out of the box, properly configured with no need for extra software. Both of the aforementioned roadblocks to usage have been eliminated. The latest version, HL2VR 1.2, now available to download here, is significantly easier to configure, and brings a number of other improvements. Additionally, Razer Hydra support required some extra software which could also be a configuration nightmare. Previous versions of the mod relied on the Vireio Oculus Rift drivers which could be difficult to configure. The HL2VR mod, made by Nathan Andrews and WormSlayer, has actually been around for some time now. The latest version of HL2VR adds new features and is easier than ever to use. HL2VR is a mod for Half-Life 2 which adds Razer Hydra support and a bunch of other tweaks, it turns Half-Life 2 into one of the best virtual reality experiences available today.
