Unreal Gold and Unreal Tournament: Game of the Year Edition mark the first additions, both priced at $9.99. Unreal II: The Awakening and Unreal Tournament 2004: Editor's Choice Edition are slated to hit "in the coming weeks."

"GOG.com provides an affordable way to buy our back catalogue of games and get up and running with minimal effort," noted Epic VP Jay Wilbur.

"We know that a lot of gamers have been waiting for new deals," added GOG managing director Adam Oldakowski. "We're sure that the Unreal games will satisfy their lust for alien blood and intense multiplayer action... DRM-free, of course."
