Though they're in completely different mediums, it's not ludicrous to compare PT, Konami's seminal horror game, to the long-demanded Snyder Cut of Justice League. The latter, of course, is a hugely revised and expanded version of the 2017 movie, with such support (including from some of its stars) that Warner Bros. eventually caved to demand and put it out in all its four-hour glory and excess. PT likewise has a cult fanbase with a desire to resurrect lost material, though whether that will ever succeed is still up in the air.
PT is short for "playable teaser," and the release was supposed to be a promo for a future Silent Hill game, Silent Hills, directed by Metal Gear Solid creator Hideo Kojima and filmmaker Guillermo del Toro, with Norman Reedus (who would later star in Kojima's Death Stranding) as the protagonist. The demo appeared as a free PS4 title in August 2014, but differed radically from both future plans and most Silent Hill games by featuring a first-person perspective, an unnamed protagonist, and above all a small, claustrophobic setting. Players would loop continuously through a dimly-lit house, gradually altering their surroundings.
The game's cult status stems from a variety of factors, including how it managed to be one of the most terrifying horror games ever made despite its limited scope. Although a radio broadcast talks about a father murdering his family, PT's creators otherwise kept exposition to a minimum, leaving players to interpret disturbing sights and sounds. In some cases these events are uncomfortably realistic, such as a wailing baby locked inside a hanging refrigerator leaking blood (for parents, that might almost be too much to handle.) The absence of exposition or even an obvious goal meanwhile led to an explosion of fan theories about the story, as well as how to solve puzzles, especially its obscure final riddle. The difficulty of solving anything is usually the game's main criticism, but if nothing else this guaranteed people would be talking.
Vanished Like a Ghost in the Night
Silent Hills was cancelled in April 2015, presumably because of Kojima's impending departure. That made PT rare enough, but the game was pulled from the PlayStation Store within a matter of days, turning any PS4 with the software still installed into a lucrative asset. People would sometimes go to extraordinary efforts to keep the game accessible, even directly transferring it to their PS5 despite no official support from Konami, which in fact killed off any backwards compatibility.
It's the union of mythology and scarcity that makes the return of both PT and Silent Hills highly demanded, to the point indie developers are creating PT clones and mods. There are even rumors of Silent Hills being back on track, complete with Kojima, which if true would certainly mirror the Snyder Cut in forcing a reluctant IP holder to give a director his due. An announcement has yet to happen, however, so nothing is certain.
