It's Christmas time for Linux games, Humble Bundle has launched Humble Indie Bundle 7. This version includes many cross platform and DRM free games. These titles includes 6 games and 1 movie for your pleasure, as the official website says:
The Binding of Isaac (and its DLC, Wrath of the Lamb), Closure, Shank 2, Snapshot, and Indie Game: The Movie! And if you pay over the average, you’ll also get Dungeon Defenders (and its DLC) and Legend of Grimrock! To top it all off, you also get a handful of awesome soundtracks in lossless (FLAC) and MP3 formats!
Epic Games hasn't allowed the release of Unreal Tournament 3 for Linux, but the first game using Unreal Engine 3 has been released for Linux. Ryan Gordon, who ported Unreal Engine 3 years ago was never allowed to release a client for Linux. The release by Humble Bundle is significant as the game Dungeon Defenders was developed using the Unreal Engine 3.
