The playable teaser (PT) for the upcoming Silent Hill game has been completely removed from the PlayStation store, and it can no longer be downloaded, even from your library. Konami announced last April that P.T. would be removed from the PlayStation store, and that the upcoming Silent Hills game was canceled. The game was no longer listed on the PlayStation store late last April, but users could still download it if it was already in their library. This is no longer the case.
People are already auctioning off PlayStation 4s with PT installed on eBay for greatly increased prices
Most people speculate that the upcoming Silent Hill game was canceled because of Hideo Kojima's departure from the company. While Konami claims Hideo Kojima quit, some people speculate that he was fired, including voice actor for the upcoming Metal Gear Solid game Donna Burke (who later recanted her statements).
Hideo Kojima still remains involved in the upcoming game, Metal Gear Solid V: Phantom Pain
