Ok guys, that's it, the official demo is now available. 3 files can be downloaded:
The demo itself, that allows you to play a full map called Valley. About 725 mb.
The demo dedicated server software, to create dedicated servers online. About 125 mb.
A special patch created by AMD/ATI to improve performances for ATI gpu owners ( like me lol ) : about 40 mb.
I'm actually downloading all this, i'll tell you
