>I read that you could access some leaked files for the official hl2 vr and get it running
It was keyboard and mouse only and didn't support any headset other than the DK2. You could supposedly get it running on other headsets at one point, but I think it got patched out.
If you're seriously desperate for VR HL2 though, you can try playing it through the GMod VR mod.
