Silent Hills (P.T)

Silent Hills (P.T ) (acronym for “playable teaser”) is a first-person psychological horror video game developed by Kojima Productions, under the pseudonym “7780s Studio”, and published by Konami. The game was directed and designed by Hideo Kojima, in collaboration with film director Guillermo Del Toro.
Released for the PlayStation 4 on 12 August 2014 as a free download on the PlayStation Network, P.T. served primarily as an interactive teaser for the game Silent Hills, a cancelled installment in the Silent Hill series. After the cancellation, Konami removed P.T. from the PlayStation Store and eliminated re-installing the game, a decision that later spawned criticism and fan efforts to allow P.T. to be re-downloaded.[1]
P.T. received critical acclaim for its direction, visuals, story complexity, and its supernatural horror tension build, but was both criticized and acclaimed for the puzzles and solutions.
