At Gamescom 2014, P.T. was unleashed on the PlayStation Store and billed as a mystery horror game, seemingly developed by a studio that didn't even really exist. Millions of PS4 users flocked to the P.T. demo, and it quickly became a horror game phenomenon. P.T. has had a profound impact on the horror game genre since its debut, and while it had a tragic fate, its still one of the top horror games released on the PS4.

P.T. stands for "Playable Teaser," as the game serves as a teaser for Hideo Kojima's canceled Silent Hills projectP.T. uses a first-person perspective and has players moving through a creepy hallway. The hallway seems to loop forever, but as players keep passing through it, they will notice strange happenings. This includes ghost jump scares, a radio broadcast that hints at a terrible fate for the player character's family, and a ringing telephone.

Figuring out P.T.'s puzzles is quite the challenge, but eventually, players were greeted with a message announcing Silent Hills and the reveal that Norman Reedus was going to play the main character. This generated significant excitement among the horror gaming community, so it's a shame that the finished product never saw the light of day.

The relationship between Kojima and Konami became strained, and eventually Silent Hills was canceled. From there, Konami removed P.T. from the PlayStation Store, so now a PS4 with the game downloaded is worth a significant sum of cash. It's also been confirmed that P.T. is not compatible with PS5 systems, so those P.T. PS4 systems may be worth even more in the years to come.

Even though Kojima was unable to realize his vision for Silent HillsP.T. itself has been hugely influential in the horror genre. P.T. directly inspired Bloober Team's Layers of Fear, which put that studio on the map as one to watch for horror enthusiasts, and it also very clearly inspired Capcom's Resident Evil 7 (and by extension, Resident Evil 8).

P.T.'s removal from the PlayStation Store makes it especially difficult for some PS4 gamers to play the game if they want to try it, so some may have to settle for fan remakes. P.T. has been created in Media Molecule's Dreams, and there have been a number of other P.T. fan remakes out there. It's not quite the same as playing the original, but it's going to be the best some horror fans can do if they want to play P.T. this Halloween season.

P.T. was available for PS4.
