What do you mean by this? As far as I can see there is no actual VR port of Portal. You can play it through something like VorpX, which gets you 3D display through a headset, but that can hardly be called "VR'd to hell and back".
Yeah, maybe “to hell and back” was strong, but it was used as the setting for “The Lab”, one of Valve’s first VR demos, and there’s a mod called “Portal Stories VR” which is one of the most developed and popular VR mods currently.
