Hideo Kojima and Guillermo del Toro's Silent Hills caught the internet by storm with its PS4-exclusive P.T. demo. Unfortunately, Silent Hills was ultimately scrapped and P.T. was removed from the PlayStation Store. If you didn't have the demo on your PS4 at the time, you were out of luck and lost your chance to play. Until now.

Reddit user Qimsar posted their v0.9 build of a PC remake in the Silent Hills subreddit. It's pretty accurate to the original demo. Qimsar wrote that they're using "almost 100% of the original assets" to capture the same creepy aesthetic of the original P.T. Gameplay of their build reveals the same repeating hallway, unsettling sound effects, and surprising jump scares. Even that baby is back.
