Games for GNU/Linux
Ballistic Overkill [Steam], the indie online FPS has been updated once again and it now features lots of voice commands and much more.
The Inner World - The Last Wind Monk, a beautiful hand-drawn adventure & puzzle game will come to Linux
The Inner World - The Last Wind Monk [Official Site] is a follow-up to the previous adventure game The Inner World, but you don't need to play the first one to enjoy it. Like the previous game, it will support Linux. I've had that confirmed by the publisher Headup Games directly over email.
You might not remember Eco [Official Site], the in-development 'global survival game' where everything you do affects the environment. They have released a juicy new update with improved performance and some new features.
