"P.T. is a free playable teaser available for download for PS4 owners, however, in order to beat it you have to get past one exceptionally trying ‘puzzle’ at the end and this method is the only one I have found to work 100% of the time for me (beaten it 3 times). I have a walkthrough of the full game here so you can skip to whatever part you are stuck on. If this helped then be sure to like and subscribe! Enjoy"
