PuniTy is a free recreation of PT
PT and Silent Hills sure have left a legendary legacy, a game everyone wanted but will ultimately never get. If you were one of the unfortunate folk that could not download PT before it was removed from the Playstation store, you can always check out the free unity based recreation PuniTy. You can download the game and read all about its development process here.
PuniTy obviously doesn’t contain any of the puzzles or all of the content from the original PT, but visually it’s a startlingly accurate recreation.
