If you haven't heard of P.T. it's a short "playable teaser" of what should have been Hideo Kojima's next game after Metal Gear Solid 5 - Silent Hills, the next game in the Silent Hill series. It was PS4 exclusive, and eventually was pulled from PSN altogether once the game was cancelled, but users continue to try to recreate P.T. on PC.
The latest version was made by user RadiusGordello in the newest Unreal Engine, and is notable for being fully playable in VR. Thankfully we don't have a VR set to test this...
You can check out and download "Unreal PT" right here. It is fully playable with or without VR, although it doesn't save at any point, and does have the occasional crash. It certainly re-creates the tasks you'll need to perform well (something most PT remakes don't bother with) and gets the atmosphere perfect. Literally the only thing that isn't quite accurate to the original demo is the behaviour of the ghost, Lisa. Nevertheless, it's well worth a go.
Other remakes of P.T. on PC include "PuniTy", as seen here, and another Unreal remake that may have not been released. There's even a remake in Far Cry 5 Arcade which is pretty neat.
One thing we won't get, though, is Silent Hills, despite the demo being the best horror game ever. Sigh.
