I thought the Quake series all supporting Linux?

Well Wolfenstein Enemy Territory had a Linux version, I'm not too sure about Quake Wars. As of now there's only a Quake Wars Server file for Linux, not the client to play the game.

*EDIT*

Looked it up and yeah they are making a Linux version, but the release date hasn't been announced yet, there's also going to be a Mac OSX version as well.

However, the Windows version got the priority first like always...so even if it is supported on other OSes you still have to wait longer.

I should've known microsoft better.
