PT, a playable teaser by Kojima Productions for the canceled Silent Hills, cannot be played on PlayStation 5.
While PT has not been available for download on PlayStation 4 since April 2015, existing downloads of the demo on PlayStation 4 cannot be transferred to PlayStation 5 or played.
However, PT was playable on PlayStation 5 at a time. Both Polygon and GamesRadar report that they played PT on PlayStation 5 in late October. But in the days that followed, PT on PlayStation 5 changed to “Playable on PS4”, which means it could no longer be played on next-generation hardware.
When it was playable, PT ran on PlayStation 5 in the same way as PlayStation 4, without noticeable problems.
According to a Sony Interactive Entertainment spokesman, the change in backward compatibility of PT on PlayStation 5 “was a publisher decision.” Konami is the publisher of PT.
