Several hidden Steam listings have been uncovered and published, thanks to SteamDB, including current PS4 exclusive Everybody's Gone to the Rapture and (sigh) Half-Life 3.

The site says the package names – previously only identifiable by reference numbers – were revealed accidentally when Valve "implemented functionality to automate some frequently asked Steam support questions such as permanently hiding a game from your Steam account."

"Due to the way Steam works, we are now also able to guess some app names that were previously unknown based on what packages they are in," says the information repository.

Some of the games, like the Steam port of Final Fantasy VI, have been announced, but not released, while others haven't even been announced yet.

SteamDB was also quick to note that third-party developers can add their own listings to the site, and some of the entries could be outdated and no longer in development – citing Halo 3 as one example that had been found similarly in the past.

A list of potential titles follows, and is to be taken with a grain of salt.
