Has any other demo had the impact of Hideo Kojima's genre-redefining PT? That stunning playable teaser for the scrapped Silent Hills may be a decade old now (sorry, yes, that made me feel ancient, too), but its legacy is still undoubtedly shaping the games we play today. One of the latest to pay homage, Supernormal, says it's the spiritual successor to Allison Road rather than PT itself, another unreleased game that was heavily influenced by Kojima's aborted horror project. But doing the one thing Silent Hills and Allison Road couldn't, Supernormal has actually made it into our hands – and while it doesn't leave the same impact as its inspirations, it certainly has a few moments worthy of them… as long as you're prepared to get through its underwhelming first half to see them.
