Retro game digital distributor Good Old Games just nabbed the venerated Unreal series for its game library. They've entered an agreement with Epic Games to sell four games from the first-person shooter franchise.

As of today, Unreal Gold and Unreal Tournament Game of the Year Edition are now available for download for $9.99 each. As with all games available on GOG, both titles been tweaked to work with Vista and XP so you won't face that strange dilemma of having too good of a computer to run a game.

Unreal II The Awakening Special Edition and Unreal Tournament 2004 Editor's Choice Edition will also be added to the GOG library in the near future. Like the other two Unreal games, they'll also carry a $9.99 price tag.
