The good folks over at NeoGAF have found some interesting new titles in the Steam database. While some of them are known to have a PC port in the works, others need a second glance to sink in. Halo: CE, Halo 2, and Halo 3 have been spotted in the database. What is even more surprising than Halo 3 coming to the PC? King of Fighters XIII of course.

Some of the titles, like Fez, are known to have a PC port in the works. Seeing them coming to Steam isn't a big surprise. But seeing Halo 3 of all things listed is. I thought I'd never see the day when Halo 3 would make its way to PC. And I might not either. Until there's confirmation, I would take this with a grain of salt. This could be a hacker trying to troll us. That said, Steam's registry is pretty trustworthy. We'll be sure to let you know if these listings are false or true when we learn more.
