If you haven't already downloaded it, you should probably hurry up because Konami is about to pull P.T. (Playable Teaser) from the PlayStation Network on Wednesday, April 29.

A notice that went up on the P.T. website gives a short, to the point notice of this removal.
The distribution period of "P.T. (Playable Teaser)" on PlayStation®Store will expire on Wednesday, April 29, 2015.

For those still unaware, P.T. was revealed at Gamescom 2014. At the time, nobody had any idea that it was a teaser for the then upcoming Silent Hills from Hideo Kojima and Guillermo Del Toro. It even featured Norman Reedus as the potential main protagonist.

A reason for the game's removal from PSN was not yet given by Konami. However, if I were to take a wild guess, I might say that this could have something to do with it. And the hopes of Silent Hills existing at all become dimmer by the day.
