In preparation for the Oculus Rift, one clever fella has claimed to have modded Half-Life 2 to support gun and head tracking.
Nathan Andrews, the creator, gives us details on the demo video shown below:
“This video shows a handful of scenes of me using the head and weapon tracking using two hillcrest trackers (the same ones that John Carmack used for the Doom 3 BFG demos of the early oculus rift prototype).”
“This video was made using my modified HMZ-T1 but others have played it on DIY rifts with the vireio stereo/warp drivers.”
If you are expecting a delivery of the Rift, you can download the mod in question from here.
