Unfortunately, the final production of the game this PT previewed was not carried through to term. Kojima had a long-standing set of issues with the production company KONAMI which ultimately lead to the two splitting ways

Silent Hills was cancelled in April of 2015, while it was suggested that Kojima left Konami in October of that same year. Konami announced they'd leave the AAA game business in September of 2015, but revealed Metal Gear Survive, their first post-Kojima Metal Gear in August of 2016. Meanwhile Kojima posts large amounts of well-curated pieces of media on Twitter and there's a new horror game in place of the last.

This one's called Death Stranding, and it contains Denmark's National Treasure Mad Mikkelsen as one of its key in-game storyline actors. This won't be Silent Hills, but it'll certainly be terrifying. Those not fully terrified will at least likely be deeply disturbed.

Death Stranding also has Norman Reedus as an actor, just as it was in Silent Hills. In the trailer above there's also an appearance of Guillermo del Toro in the digital flesh. It's been suggested by Kojima that the game will be released some time before the year 2019 with Kojima Productions as developers and Sony Interactive Entertainment as publisher.
