Yet to be released on PC, a Halo 3 listing has turned up in Steam’s registry files – along with PC ports of Halo 2 and Halo Combat Evolved. While not a surefire sign these will make their way over to Valve’s service in the near future, registry leaks have been reasonable for outing many titles in the past – Alan Wake being a prime example.

Over the past year, Microsoft has brought over a few games to Steam, including Fable III and Age of Empires III. A belated release of the Halo titles might strike us as odd – especially with the way the company is pushing its Xbox Live storefront on Windows 8 – but certainly not out of character.

First spotted by NeoGAF, other notable listings exposed in the registry leak include Duke Nukem 3D: Atomic Edition, Fez, Dyad, Quantum Conundrum 2, The King of Fighters 2002 Unlimited Match, and Shadow Warrior Complete. Before Valve removed the entries, community hubs for Halo were accessible via Steam as well.

Judging from previous Steam leaks, we could be waiting awhile for these titles even if they do appear eventually, but it’s a glimmer of hope especially for those that have been waiting for more Halo on PC.
