Microsoft has no plans to release the 'Halo 3' game on Steam, despite the fact that stubs for Microsoft's popular game series were discovered during a scrape of the Steam database.

Microsoft told Eurogamer that "Halo 3" won't be coming to the PC via Valve's digital distribution portal.

The scrape also found entries for "Fez," which is being prepared for release on other platforms after an Xbox 360 debut in 2012, as well as PlayStation 3 title "Dyad", which is headed for the computer in March.
