Everybody's Gone to the Rapture had a Steam database listing for a long time now but everyone simply assumed this was a leftover from before the Chinese Room partnered with Sony and made their game a PS4 exclusive.

Since then there were rumors of Everybody's Gone to the Rapture and a few other games being ported over to the PC, and while the fact that the game now has a store-front banner image in the Steam database isn't definitive proof I think we can safely assume that the PS4 exclusive "walking simulator" will be making its way to the PC sometime soon.

The banner image addition was discovered by BernardoOne from Neogaf who noticed that the dormant Everybody's Gone to the Rapture Steam app started receiving updates after months of inactivity. Soon after the news broke out the app was set to hidden status and its name obscured, though you can still see the previous name on the Steamdb listing.

During the same batch of Steam helpdesk leaks that first showed Everybody's Gone to the Rapture might be coming to the PC you could also see listings for Final Fantasy X & X-2 which at that point sounded a bit far-fetched but given how many Final Fantasy games are currently on their way to the PC I have a feeling that the leak was more than just fabrication.

As of right now however there is no official confirmation so despite all of this being extremely likely I'd still suggest you take it with a grain of salt. Once more information comes in I'll make sure to update you.
