After beginning as a distribution of games made by its owner, Valve Software, the Steam download service has blossomed into a full-fledged content delivery system for a variety of publishers. The past year has seen such high-profile companies as Sega, Atari, Capcom, Codemasters, 2K Games, id Software, Eidos Interactive, and Rockstar Games distribute games from past and present catalogs on the service, which claims over 15 million subscribers.

　　Today, another celebrated developer announced it would be hawking its wares via Steam. Starting today, five installments in Epic Games' popular Unreal series--Unreal Gold, Unreal 2: The Awakening, Unreal Tournament: Game of the Year Edition, Unreal Tournament 2004: Editor's Choice Edition, and Unreal Tournament 3--will all be available on the service. The games can be bought separately for prices ranging from $8.95 to $44.95, or together via the single Unreal Deal Pack for $59.95.

　　From now until March 24, all Epic Games' offerings are temporarily 10 percent off on Steam. Unfortunately, the North Carolina-based studio's award-winning shooter Gears of War, which was released on PC last year, is not currently available on the download service.
