Valve is no stranger to new technology, especially the Oculus Rift VR headset. The studio previously supported the headset with Team Fortress 2, and now it's doing the same with Half-Life 2. However, HL2 support is "more raw" than TF2's support, according to Valve's Joe Ludwig, who led development on bringing TF2 to the Oculus Rift.
This port is a bit more raw than TF2 was when it shipped, so we would appreciate hearing about any bugs you find. Just like in TF2 this mode is experimental, so we really want to hear what you think.
Anyone with an Oculus Rift headset can opt-in to the appropriate beta on Half-Life 2 to try it out. Report any bugs you encounter so Valve can make the VR version of HL2 is the best it possibly can be. If you'd rather wait for any bugs to be corrected, Ludwig said a final version should be released for "everybody in a few weeks."
The beta also adds support for SteamPipe, which is the new content distribution system for Steam. Valve is experimenting with adding Oculus Rift support to other titles, like Portal and Left 4 Dead, but those are farther out due to making sure the UI and reticules translate properly. Also to make sure no one gets motion sickness while gaming, because that wouldn't be great to happen.
However, leave it to a modder to add Oculus Rift support to the likes of Skyrim and Minecraft. Both videos showing the games off are rather long, but definitely worth checking out to see just how each world looks in virtual reality.
