For one.... Kojima productions doesn't do the Silent Hill series. And for another, if you check all the games Kojima has made. Only one series runs up to a fourth installment, Metal Gear. So the only possible game would have to be MGS5. And too the code amply states that as well. Most people don't think to look up the code when viewing a website. Check your facts before you go off on a handle saying it's this game or that game.
