If you're looking for an excuse to take another trek through City 17 and points beyond, and you've got an Oculus Rift developer kit handy, you can now opt in to a beta build of Half-Life 2 with support for the VR peripheral. It's as simple as adding "-vr" (without quotes) to the Set Launch Options line in the game properties, and making sure you've opted into the beta for SteamPipe.
"This port is a bit more raw than TF2 was when it shipped, so we would appreciate hearing about any bugs you find," Valve's Oculus port master, Joe Ludwig, wrote on the Oculus Dev forums . "Just like in TF2 this mode is experimental, so we really want to hear what you think."
Ludwig also cautioned about a couple of known issues, such as the overall HUD not always being bright enough to be easily readable, and UI elements appearing mis-positioned when zooming in. Gordon Freeman will be joining the likes of Minecraft Steve and pilots in CCP's dogfighting prototype in Rift space.
