Bad news for everyone who deleted PT from the PS4 and figured they could always redownload it. According to Kotaku, the demo has been completely wiped from the PSN servers, meaning that even if you had it before you’ll never be able to get it again. This goes against the standard scenario on the PSN, where users could always, although not anymore, redownload a game they had purchased or put on their system.
This update comes after the announcement that Silent Hills, which PT turned out to be a teaser for, was cancelled.
Bottom line: If you have PT on your PS4, don’t ever delete it if you have the slightest thought that you’ll want to replay it.
