After a search of the Steam database, NeoGAF users found the entry for Halo 3. Though this doesn’t confirm that it is coming out on the PC, it does leave up with the possibility that Microsoft will bring the game to PC users. To add to the speculation, Valve has since removed the entries to prevent further searches, but the damage was done.
While Steam leaks are generally correct, the amount of time it takes to bring the database entry to market can vary wildly. Either way, are you looking forward to playing the game on the PC? Let us know in the comments below.
